Is there hope for a dying river in Kenya's growing capital?

NAIROBI, Kenya (AP) — Vultures scavenge for dead animals along a river turned sewer conduit in Kenya’s capital Nairobi. Its waters turn from clear to black as it traverses informal settlements and industrial hubs. The river and its tributaries cross Kibera, known as Africa’s largest slum with close to 200,000 residents, and other informal settlements. It skirts dozens of factories that manufacture textiles, liquor and building materials. Many have been accused by environmentalists of discharging raw sewage and other pollutants like oil, plastic and glass into the water.Experts and locals alike fear the water is harming plants in nearby farms that feed residents. Some community-based organizations help clean up the river and the government is also hoping to ramp up efforts. But families in the rapidly growing downstream suburb of Athi River, some 30 kilometers (19 miles) away, say they can no longer rely on the water for basic needs.ADVERTISEMENT25-year-old Anne Nduta uses the river’s dark waters to wash her babies’ clothes by hand.“When it rains, the Athi River water is usually full of garbage, and when it clears a bit we use it to wash clothes,” said the mother-of-two. “But as the dry season continues, the water becomes darker in color and we have to start buying expensive borehole water.” A 20-liter (5-gallon) jerrican of borehole water sells for 20 shillings ($0.16), and Nduta would need four of them to wash her babies’ clothes every three days.Her problems start upstream, where informal settlements have directed some of their sewer lines straight into the Nairobi River.The new national government, installed after the August election

Why many plastic promises are just greenwashing

At this point, there’s no denying that plastic pollution is ubiquitous. It appears in the remote corners of the Earth, the food chain, and even human bodies. To protect human and environmental health, global plastic pollution must be addressed.

With increasing public concern about climate change, companies might face higher expectations regarding corporate responsibility, especially those known to cause significant environmental impacts. 

In a recent One Earth study, the authors looked into the commitments made by the world’s largest companies between 2015 to 2020 to reduce plastic pollution. Based on the study, about 72 percent of the world’s largest companies have made some form of commitment to reducing plastic pollution, which ranges from one line of text to many pages of commitment. 

Although some companies have made commitments in recent years to reduce their plastic footprint, the work doesn’t end there—it’s necessary to analyze how effective they are at reducing plastic pollution. 

Corporate commitments have a limited impact on global plastic pollution

There’s no penalty for not fulfilling a non-binding commitment, especially when it comes from the company itself. It’s important to validate whether or not companies are doing what they actually promise to do, says Shelie Miller, a professor of sustainable systems at the University of Michigan.

Companies’ commitments frequently involve waste reduction strategies, like increasing recycled or recyclable content in packaging and advancing recycling-related efforts, notably paying less attention to how virgin plastic production can be reduced. For example, Nestlé Waters North America—now known as BlueTriton Brands—made a goal in 2008 to double the recycling rates for PET plastic, the kind of plastic used for water bottles, to 60 percent. However, the National Association for PET Container Resources (NAPCOR) reported in 2018 that the average recycling rate of PET bottles hasn’t changed that much over the past decade.

Based on current trends, efforts to improve waste management may be overshadowed by the production and consumption of virgin plastic. Annual virgin plastic production is estimated to increase to 1.1 billion tonnes in 2050. By that time, the petrochemicals used to produce virgin plastic polymers may very well account for nearly half of the growth in oil demand, surpassing trucks, aviation, and shipping.

“We found limited evidence to suggest that corporate commitments are actually reducing the amount of global plastic pollution,” says Zoie Diana, a PhD candidate in the Division of Marine Science and Conservation at Duke University and author of the recent One Earth study. “Unfortunately, we found reports of companies lightweighting plastic.”

Lightweighting is a practice where companies slightly reduce the volume of plastic in their packaging, like making thinner PET bottles or shorter bottle caps, which you’ve probably already noticed in your local grocery store. While it’s good that companies produce lighter and smaller plastic products, if they reinvest their savings into markets that involve new plastic products, they might only increase the total mass of plastic produced, says Diana.

Companies usually strive to increase their sales, so even if less plastic is used per package, the number of packaging units is likely to increase. For instance, products like shampoo or coffee are often sold in tiny packets or sachets, which use more packaging material compared to larger product sizes. In addition, reducing the weight of plastic packaging doesn’t make the product any less likely to become trash.

Sometimes, consumers are misled by products that aren’t as green as they seem. Bioplastics, produced wholly or in part from renewable biomass sources, are considered the more environmentally friendly alternative to petroleum-based plastics. However, they can still contribute to plastic pollution, global warming, and land use because not all bioplastics are the same and they aren’t always biodegradable.

While some bioplastics like those derived from cornstarch decompose in the soil, others only break down at high temperatures or after being treated in a landfill under very specific conditions. Even biodegradable bioplastics can still end up in landfills and produce methane gas as they decompose. Bioplastics made from crops also use up land that could have been used for growing food. It’s important to remember that bioplastics are still just plastics, even if they are made from a different material.

Boxed water products, often touted as an eco-friendly alternative to bottled water due to the paper-based carton packaging, also appear to be better for the environment than they really are. In reality, the cartons aren’t made entirely from paper because they require plastic film and aluminum to waterproof the paper and seal the content. Moreover, they’re not necessarily easier to recycle. Only 60 percent of households in the country have access to carton recycling, whereas 87 percent of the U.S. population has access to a municipal collection of PET bottles.

Companies must reduce plastic production and overall consumption

Although recycling is an important step aimed at reducing plastic pollution, it’s not that effective. A 2017 Science Advances study reported that only nine percent of the plastic ever created had been recycled. Aside from the 12 percent of plastics that were incinerated, this means that all the plastics that were produced remain in landfills or the natural environment, continuing to pollute the planet. Even if recycling efforts were improved, they might be unlikely to keep pace with the growing rate of plastic consumption.

“We suspect that, at best, the emphasis on recycling found in this study reflects industry efforts to raise global recycling rates and, at worst, reflects industry attempts to shift responsibility toward consumers, greenwashing, and potential pre-emption of legislation aimed at reducing plastic pollution,” says Diana.

A number of companies recently explored creative ways to minimize their plastic use. In 2018, brewing company Carlsberg introduced its Snap Pack to dramatically cut plastic waste. They did away with plastic rings by bonding a six-pack of beer cans together with glue instead. When all of their four-, six-, and eight-pack beers globally have been converted to use this innovation, it would save about 1323 tons of plastic annually, the equivalent of around 60 million plastic bags. Meanwhile, Walmart Canada eliminated plastic wraps of organic banana bunches and single peppers in 2019, preventing almost 94,000 kilograms of plastic waste. 

Commitments like lightweighting and more recycling only divert attention from preventive measures that reduce virgin plastic production. The tap on unnecessary plastic production must be turned off, but only three percent of the top 300 companies on the Fortune Global 500 explicitly targeted virgin or newly produced plastics, says Diana. Unilever has a current pledge to halve the amount of virgin plastic they use in their packaging by 2025.

“Many companies focus on making packaging more recyclable or increasing the recycled content in their products,” says Miller. “While these efforts are an improvement over the status quo, they do not fully eliminate the environmental impacts of plastic.”

[Related: Dozens of companies with ‘net-zero’ goals just got called out for greenwashing.]

According to PepsiCo, 87 percent of its packaging is recyclable, compostable, or biodegradable. The multinational food, snack, and beverage corporation hopes to reach 100 percent by 2025. However, Miller notes that improving the ability of packaging to be recycled doesn’t necessarily ensure that it will actually be recycled in practice. Furthermore, a recyclable plastic that escapes waste streams and ends up in the environment can cause just as much ecological damage as a non-recyclable one, she adds.

The environmental impact of plastic pollution can only be partially addressed through improved packaging and recycling efforts because plastics don’t just cause harm when they are discarded. Starting from their production, they already contribute emissions that occur through natural gas extraction and plastic manufacturing. In the United States alone, fossil fuel extraction and production associated with plastic manufacturing contributed at least 9.5 to 10.5 million metric tons of CO2 equivalents back in 2015. Therefore, reducing plastic production and consumption remains to be a critical part of addressing plastic pollution.

“We tend to focus on visible impacts such as solid waste generation, but there are also upstream environmental impacts that are usually invisible to us,” says Miller. “The best way to reduce the environmental impacts of plastic is to reduce overall consumption. Reducing the amount of stuff that we consume is key to reducing environmental impact, not just making it easier to recycle.”

Student project tracking microplastics found in Bering Strait-area spotted seals

Microplastics pollution has infiltrated regions all around the world, from heavily developed and urbanized areas to remote sites that include the Greenland Sea, the high altitudes in the Alps and the waters and snows of Antarctica.
Now add to that list the bodies of Bering Strait spotted seals.
Microplastics are tiny bits of plastic, generally no bigger than a sesame seed. They are carried on ocean currents, in freshwater bodies and moved around the atmosphere through winds. They are known to be harmful to fish and birds that mistake them for small bits of food.
A University of Alaska Fairbanks graduate student has found them in the stomachs of spotted seals harvested in the Bering Strait region. Of 29 stomachs that Alexandria Sletten examined, all but one held tiny bits of plastic. In all, there were 162 pieces recovered, 161 of which were fiber bits and one that was a clear fragment.
Sletten presented her results at a poster session at this week’s Alaska Marine Science Symposium held in Anchorage.
The stomachs she used for sampling were from seals harvested in 2012 and 2020 by residents of Shishmaref, an Inupiat village on the Chukchi Sea coast, and Gambell, a Siberian Yup’ik village on St. Lawrence Island in the northern Bering Sea. They were made available for her research through the Alaska Department of Fish and Game’s Ice Seal Biological Monitoring project, through which seal hunters donate specimens that are stored and made available to researchers.

Sletten’s sorting revealed no significant difference separating the 2012 seals from those harvested in 2020, which went contrary to her expectation that amounts of microplastics would increase over time. “I’m finding that it’s been there and it’s always been there” over those years, she said. 
Similarly, no pattern separated pups from older seals, also a bit of a surprise. “I did expect to see a bit more difference,” she said.
But the presence of microplastics in the animals’ stomachs in general was no surprise, she said. “It’s unfortunately something very ubiquitous for the Arctic and for the world,” she said.
As is the case elsewhere, scientists in Alaska have been working for years to better understand the presence and spread of microplastics in the environment. Some pioneering work focused on Bering Sea and Aleutian birds, tracking not just the plastic bits in their bodies but even the chemical contaminants called phthalates that spread into body tissues and even eggs from ingested plastics.
However, there has not been a lot of research into microplastics in Alaska marine mammals, something that’s unfortunate in a region where many people depend on hunting marine mammals for food, she said.
Sletten is using this research in her thesis for her master’s degree in marine biology. She intends to do further work, with many more samples, to better parse out life stages of the seals, seasons of harvest and other factors that might correspond to varying levels of microplastics.

Plastic works its way up the food chain to hit fishing cats, study shows

A recent study published in the journal Environmental Pollution found plastics in the scat of fishing cats dwelling in urban areas near Colombo, Sri Lanka.Different sizes of plastics, from micro to macro, were found in some samples, and were believed to have been ingested by the cats via their prey.Potential health effects on the vulnerable small cat species are unknown, but based on knowledge of the impacts of plastic on other species there is cause for concern, say conservationists. During a dietary study on fishing cats living near Colombo, Sri Lanka, researchers made an unexpected finding: Some scat samples collected contained plastics. Varying in size from tiny microplastics to larger debris in the form of macroplastics, these findings are cause for concern for the vulnerable species, say conservationists.
The results were “a bit of a shocker to all of us,” Anya Ratnayaka, a co-founder of the Urban Fishing Cat Conservation Project and lead author of the paper, told Mongabay in a video interview. The team collected 276 cat samples from fishing cats living in and around Colombo’s urban area and found that six contained plastics. “The fact that we even found any is a bit worrying,” she said.
Fishing cats (Prionailurus viverrinus) are a wetland-dependent species and eat a varied diet of fish, birds and small rodents. As they are not known to forage in or eat trash, it’s thought that the species was exposed to plastic via its prey; thus the researchers believe this is likely a case of trophic transfer, in which contaminants travel up the food chain. The results were recently published in the journal Environmental Pollution.

“All three plastic types were found in scats containing rodent remains, while meso-, and macroplastics were found in scats with avian remains, and micro- and macroplastics in scats containing freshwater fish remains,” the authors write.
Bits of single-use plastic bags and pieces of nylon and polyester string were among the debris found in the scat, Ratnayaka said. Fishing cats tend to gut their prey prior to eating, which may explain why only a fraction of the samples contained plastic, she added.
Previously, researchers in Nepal also found plastic and glass in fishing cat scat around Koshi Tappu Wildlife Reserve. “The plastic pollution is going to be much higher [in urban areas],” Ratnayaka said. “But the fact that this is also happening in more wild, natural spaces is kind of alarming.”
Though research on the impacts of plastic ingestion on terrestrial wildlife is limited, the researchers say it could cause digestive blockages or leach harmful chemicals.
The fishing cat’s dietary habits and likely route of exposure add “another dimension to the problem of plastic pollution,” according to Michael Bertram, assistant professor in the Department of Wildlife, Fish, and Environmental Studies at the Swedish University of Agricultural Sciences. “Clearly, ingestion of potentially harmful pollution originating from anthropogenic activities by animals of this species is cause for concern,” Bertram, who was not involved in the research, wrote in an email.

Conservationists are aiming to install traps at river mouths to reduce the flow of plastic into fishing cat habitats. The problem can be particularly severe during the monsoon season, Ratnayaka said. Image courtesy of the Urban Fishing Cat Conservation Project.
The IUCN, the global wildlife conservation authority, considers fishing cats to be vulnerable across their range, which spans South and Southeast Asia. Like other wild cat species, they face a plethora of threats, including habitat loss, persecution, pollution and disease. Given the rapid conversion and destruction of the wetland habitats on which they depend, the species is particularly at risk.
“The new study provides one more lens to analyze threats affecting fishing cats and is very, very concerning,” Tiasa Adhya, a wildlife biologist and co-founder of The Fishing Cat Project, who was not involved in the study, wrote in an email.
In her view, the study’s findings also raise further questions, such as how other threats are combining with indirect plastic consumption to impact the species, and what this exposure might mean for younger cats. “It is worth continuing to study the impact of such pollutants on the long-term survival of populations and any effect these might have on the genetic makeup of populations,” she said.
Following the study, the conservationists are aiming to install plastic traps on river outlets flowing into wetland areas and to investigate plastic levels in the guts of the cat’s prey species, such as fish and waterbirds. “I feel that everyone is concentrating on marine environments, but we also need to try and figure out what’s happening in our terrestrial and freshwater systems as well,” Ratnayaka said.

Minnesota lawmakers rush to introduce bills cracking down on 3M chemicals so cancer victim can testify

Minnesota lawmakers plan to introduce several bills cracking down on certain chemicals, rushing to hold hearings so that a young Woodbury woman who is dying of cancer can testify.
Maplewood-based 3M has made a group of chemicals called per- and polyfluoroalkyl substances (PFAS) since the 1950s, but failed for decades to report to regulators and scientists that they could be toxic to humans, animals and the environment. The company announced in late December that it plans to stop making PFAS and stop using the chemicals in its products by the end of 2025. Other companies still make the chemicals, and will continue to do so. 
Amara Strande, 20, was featured in a December Reformer series about the dangers of the 3M chemicals and how the company sought to conceal it. Strande is a graduate of Oakdale’s Tartan High School, where she was among an alarming number of students and graduates who got cancer. 3M stopped making some of the chemicals in 2000, and Oakdale began filtering its contaminated water in 2006.
Several bills are in the works: One would ban PFAS chemicals in firefighting foam. Another would require manufacturers selling products with PFAS in Minnesota to disclose that to the state. A third would ban all non-essential use of PFAS chemicals.
Passing both chambers of the Legislature and winning a signature from Gov. Tim Walz won’t be easy, given the powerful influence of 3M, which employs 13,500 Minnesotans and has wide-ranging sway among both parties. 3M said in a statement that it continues to support PFAS regulation “based on the best available science and established regulatory processes” but the  regulations should be “crafted carefully to meet regulatory objectives and help maintain the availability of important products that are made with PFAS.”
Avonna Starck, state director of Clean Water Action, said the three bills have been drafted and are waiting on bill numbers, but hearings may be held before they get numbers so Strande can testify.
“Everyone I have talked to in the Legislature who has heard her story is motivated to get it moving,” Starck said.
Sen. Tou Xiong, a Maplewood attorney, went to Tartan High School from 2004 to 2008.
“I know exactly what Amara is talking about,” he said. “Cancer is definitely a thing that was around.”
He remembers when state health officials announced in 2005 that 3M chemicals were detected in five Oakdale city water wells.
“We were like ‘Oh there’s contamination coming from 3M,’” Xiong said. “We didn’t really know anything else… I don’t think the teachers wanted to alarm us either.”
He’s working to draft a bill patterned after a first-of-its-kind Vermont law that allows people exposed to toxic chemicals to sue responsible companies for the cost of monitoring their health.
Vermont lawmakers pushed for the law after a now-shuttered Bennington plastics factory contaminated about 8,000 residents’ drinking water, leading to a $34 million class-action settlement, including a $6 million medical monitoring fund. 
Courts in about 16 states have recognized the right to seek medical monitoring through case law, but Vermont’s law marked the first time a state put that right in statute, leaving no question that victims could seek reimbursement of medical monitoring costs, according to Safer States, a national alliance of environmental health organizations. 
The Vermont law also allows the state to sue manufacturers “who knew or should have known that the material presented a threat of harm to human health or the natural environment” for cleanup costs, according to the Associated Press.
Xiong said he’s been working for years with Woodbury and 3M to address city water wells shutting down in connection with 3M’s $850 million settlement with the state over chemical contamination.
“I think everybody wants to make sure that our communities are safe and that we address the PFAS forcing our community to close our wells,” he said. “I think it’s just finding the right path.”
The chemicals persist in the environment and humans, and can be found in the blood of people across the world. They can be found in wildlife in the Arctic circle and drinking water, rivers and streams. 
Beginning in the 1950s, 3M dumped thousands of gallons of industrial waste containing the chemicals into four landfills east of the Twin Cities, where they migrated into four aquifers used for drinking water and ended up in groundwater.
By 2017, a 100-square-mile underground plume east of St. Paul was contaminated with the chemicals. Today, the plume is about 200 square miles, according to state regulators.
While numerous people in the East Metro have suspected they may have been sickened by the contaminated water, help has been elusive.
Robert Bilott sued DuPont over chemicals polluting West Virginia farmland near its Teflon plant and won a landmark 2004 settlement. 3M manufactured the chemical for DuPont beginning in the 1950s. 
Oakdale residents then recruited Bilott to help with a Minnesota lawsuit against 3M, but Minnesota law doesn’t allow medical monitoring claims to be pursued in class-action suits. So the Minnesota case could not lead to the kind of settlement reached in West Virginia, where thousands of people were monitored, and an independent panel of scientists later linked chemical exposure in drinking water to six diseases, including two types of cancer. 
Bilott said in an email, “Having the ability to seek medical monitoring in response to exposure to toxic substances has been a critically important tool for those exposed to PFAS across the country.”
He filed a class-action lawsuit in 2018 in federal court on behalf of people exposed to the chemicals made by 3M and other companies. He’s not seeking monetary damages but wants the companies to fund a scientific panel to determine how much harm the chemicals are causing. In April, a judge certified the class-action lawsuit to go forward for Ohioans, but the chemical companies appealed the consideration of adding other Americans to the case. 
Ban on all but essential use of PFAS

Rep. Jeff Brand, DFL-St. Peter, is author of a bill banning all “non-essential use” of PFAS chemicals in products. They’re found in car seats, carpeting, cosmetics, ski wax, cookware, food packaging, fabrics and cleaners.
“It’s everywhere and it’s just insane,” Brand said.
Brand said research has shown the chemicals can be found in breast milk. 
“All I’m trying to do with my legislation is turn off the tap,” he said. “The bathtub has been overflowing for a long time.”
What uses would be considered essential? Not many, he said. Certain medical devices and airplanes, for example.
“Wouldn’t it be nice if you had to prove it was safe before it could be included in products?” he said. “In the name of all the Amaras of the world,” he said, referring to Strande, the young woman featured in the 3M Reformer story. 
In 2017, a nearly 15-pound tumor was found in Strande’s liver, and she was diagnosed with a rare cancer called fibrolamellar hepatocellular carcinoma; it strikes one in 5 million Americans ​​between the ages of 15 and 39.
She’s since had more than 20 surgeries to battle tumors. In recent months, tumors grew next to her heart, wrapping around her upper right chest, fracturing her ribs. Surgery is no longer an option, and there is no cure. 
Even though she is in “more profound pain,” she wants to testify in person, if she is physically able, her mother Dana said.
“It’s very important for me to testify because my life has been significantly changed,” Strande said. “I’m really sick of seeing other people also go through similar losses with cancer and disease.”

Are compostable bags as environmentally friendly as we think they are?

Walk into any supermarket or retail store and the chances are you will see a variety of bags and packaging marked as compostable.

For eco-friendly shoppers the world over, this can only be a good thing. After all, we all know that single-use plastics are the scourge of the environment, and to be avoided at all costs.

But are many of the items being branded as compostable actually good for the environment? Or is it the case that many of us are using them incorrectly? Perhaps we assume they are home compostable, when the reality is they are only compostable in larger facilities. And do they really harmlessly break down, or is this another example of greenwashing in action?

According to research conducted by packaging platform Sourceful, only 3% of compostable packaging in the U.K. ends up in a proper composting facility.

Instead, it claimed a lack of composting infrastructure means 54% goes to landfill and the remaining 43% gets incinerated.

Sourceful’s CEO and co-founder, Wing Chan, said the practical reality of compostables “does not reflect the narrative used to market them”.
“We recommend avoiding and looking to switch out where possible in your supply chain,” added Chan.
Dr. Tarun Anumol, from Agilent Technologies, said plastic bags are commonly made from the polymer polyethylene, which depending on the conditions can take up to 1,000 years to fully break down in the soil.
And when they do start to disintegrate, Anumol added they can frequently break down into micro-plastics, which research shows can contaminate the soil, be absorbed into crops or pollute nearby water streams.

Once in the water supply or food chain, they can then be ingested by humans and enter the bloodstream.
In addition, he said microplastics can also attach to other pollutants and even increase the toxicity of other substances in the soil, like chromium and other organic pollutants.
In terms of compostable bags, he said many of them take between 10 and 60 days to degrade in the soil, depending on favorable environment conditions.
He said in some instances, home composting does not necessarily provide the right environmental conditions for decomposition, so the bags may “stick around for a lot longer” but still not as long as traditional plastics.
Anumol said it was important that the right disposal systems are in place to manage compostable bags, but he added this is really a “teething issue” that will be sorted out over the next few years.
But he said it was still vital that soil is regularly tested and analysed for possible contaminants to ensure safe and fertile soil.
Sarah Paiji Yoo, the CEO and co-founder of the eco-friendly cleaning product firm Blueland said ultimately, she believes compostable bags are still better than virgin plastic bags, because they are not made with petroleum-based plastic.
But she added compostable bags need to be industrially composted to truly effectively degrade.
“Compostable bags that are put in the trash can last in a landfill for tens and hundreds of years since objects in landfills,” she added.
The CEO of plant-based fiber packaging manufacturer Footprint, Troy Swope said he believes we are “not quite there yet” with compostable bioplastics.
“When we started Footprint, we considered bioplastics, but ultimately we found the best solution for the planet was a nature-based solution,” Swope told Forbes.
Swope said they use recycled cardboard, paper and other natural substances, like algae to develop a fiber, which in turn, can be used to create biodegradable packaging.
“We want solutions that nature can digest, so that if it got into a river and into your ocean, it would break down will not harm sea life,” he added.
And Graham Rihn, founder and CEO of the waste management platform RoadRunner Recycling, said it was important to draw a distinction between biodegradable bag liners and compostable liners, which he added are designed for a very specific function.
Ultimately, he said if there is compost service available, then “you should absolutely use compostable products, if at all possible”, because it will leave a far smaller footprint on the environment than the alternative.

Why your recycling doesn't always get recycled

A plastic bag, a dirty pizza box, plastic utensils, paper napkins, and a soda can—a single takeout meal can feel like a game of recycling trivia. Which items can be recycled? What kinds of plastic go in the trash? What if the container is greasy? Recycling can be complicated, and the rules outlining how to do it vary from city to city, which might be one reason why only about 32 percent of our trash gets recycled.  Only about six percent of the plastic—everything from plastic bottles to IV drips—produced in the U.S. in 2021 was recycled, according to a Greenpeace report. Some plastic items are designed in ways that make them difficult to recycle or recyclers struggle to find people who want to buy recycled material. That’s an issue for the environment and human health—all that plastic breaks down into microscopic pieces and contaminates everything from the ocean to our bodies.We do best with paper—68 percent of that gets recycled. But experts say there are changes you can make to improve recycling at home, in your community, and with your vote. Which plastics can you recycle? Want to better sort trash from recycling? Don’t be fooled by the triangle made of interlocking arrows imprinted on plastic. Those triangles don’t necessarily mean that an item is recyclable—they simply indicate its “resin code,” one of seven categories that denote the type of plastic it’s made of. Only some of these categories are fit for the recycling bin. (Find more details on each resin here.) “Plastic is extraordinarily finicky,” says Darby Hoover, a recycling expert at the Natural Resources Defense Council. “When you make a plastic package or item, you add dyes, and additives that change its properties to make it as rigid or as flexible as you need it to be. And all those little additives affect its melting point and ability to be recycled.” Plastic resin codes were intended to help recycling facilities, but a 2019 survey of 2,000 Americans showed 68 percent of participants thought the interlocking triangle symbol meant a product could be recycled. These plastic symbols are so often perceived as indicating recyclability that California recently signed a law restricting its use. Experts say you should research which plastics your local recycler accepts, but as a general rule, plastics labeled with a number one or two are most likely to be recycled. Those are the rigid plastics like water bottles and milk jugs, and recycling plants have machines designed to clean, shred, and melt down this type of plastic. Plastic labeled with a five, found in certain types of food and medicine bottles, could potentially be recycled in your community, but its acceptance varies.The other plastics—three, four, six, and seven—are more likely to be dumped in a landfill if tossed in your household recycling bin. These types of items include bubble wrap, shopping bags, and flexible food packaging. “One of the biggest problems is called ‘wish-cycling,’ where we wish something could be recycled so we put it in the recycling bin and cross our fingers,” says Hoover. But it’s a waste of time, she notes. At best it simply finds its way to a landfill. At worst, it jams up recycling machinery and has to be removed by hand, a process that slows down operations. “Those plastic bags wind away around the screens, and you have to physically cut them off. They are the bane of our existence,” says Marti Matsch, the deputy director of Eco-Cycle, a Denver, Colorado-based recycler.Matsch says, on average, Eco-Cycle has to throw away about 10 percent of the recycling it collects in the trash because residents toss in items that can’t be recycled—everything from plastic bags to clothes.(Learn more about the environmental challenges of plastic wrap.) Do you really need to clean your recycling?Another change you can make to increase the odds of your recycling getting recycled is by making sure you keep your bin free of contamination from food, dirt, or chemicals. Paper, for example, is best processed when it’s clean, and any food particles or moisture on other recycled items could mean that paper never gets recycled. That’s why greasy pizza boxes, for example, typically go in the trash instead.(Want to recycle your food scraps? Read our guide to composting.) Cities and towns will often provide residents with guides outlining exactly what they can recycle. In Washington, D.C., for example, you can learn how to dispose of an item by searching the city’s database. The Recycling Partnership, an organization dedicated to improving the recycling system, has a national database that can help you navigate recycling in your local community.Where does your recycling go?Selling recycled material is one way communities offset the cost of collecting, sorting, and processing recycling—and so a crucial part of successful recycling is finding a buyer for recycling material. But demand for that material varies, which is why some communities do not accept all types of recycling.Recycled aluminum is valuable because the metal can be recycled over and over without degrading, unlike plastic, which is often turned into lesser-quality material and used to make new products like carpet or lumber. In Colorado, there’s an active market for plastics labeled with a number five, says Matsch, so Eco-Cycle accepts that resin.But generally, recyclers face more challenges finding buyers for plastic. The same additives and dyes that produce different shapes, textures, and colors of plastic also make it difficult to produce a material worth buying. “With all that variation, it’s very difficult to find buyers to take that material and turn it into something new because they’re looking for a simple recipe, not something so complicated,” says Matsch. For decades, that buyer was primarily China, which imported millions of tons of used U.S. plastic. But in 2017, China increased its standards for the plastic it was willing to purchase and left U.S. recyclers without a buyer. Some of that went to other countries like Indonesia and Mexico or was tossed in a landfill. Increasingly, however, some companies—Target, for example—are committing to use more recycled materials from recycling plants. How to make recycling more effective One solution, say environmental policy experts, are more “bottle bills.” If you live in one of the 10 states where these laws are in effect, you may have noticed soda bottles with anywhere from five to 15 cents printed on the label. This creates a set value for a bottle and incentivizes consumers to bring them to a participating recycling container. A 2020 report on litter found that states with bottle bills have half as much litter as those without them.Drop-off sites are also helpful for collecting plastic bags. Some grocery stores offer plastic bag drop-off sites where bags are more likely to be kept clean and can be taken to speciality recycling centers. “Another thing that’s extremely important is for folks to look at what’s happening policy wise and to support efforts to reduce waste,” says Hoover. Many cities are setting “zero waste” targets that embrace more recycling as one strategy to keep waste out of landfills.  However, some environmental experts say we need to think outside of the blue recycling bin if we really want to stem the flow of plastic pollution entering the environment. “The best thing we can do for taxpayers is make less waste,” says Judith Enck, a former EPA regional administrator and president of the environmental group Beyond Plastics. In recent years, some states have adopted legislation that makes producers responsible for the recyclability of their product. These laws vary in their approach, but they might require a manufacturer to financially contribute to recycling centers or to change the design of their product to be more easily recycled. One new approach to recycling Enck wants to see more are programs that allow for bottles and other packages to be washed and refilled. She cites Coca-Cola’s recent announcement that it will try to refill or reuse a quarter of its glass and plastic bottles by 2030 as an example of changes top plastic polluters like the beverage company should make. Enck also points to smaller scale initiatives, such a start-up that washes and refills bottles in a vending machine. “That is the future,” she says. “That is what we need.”

Turning problem sea algae into a replacement for plastic

ObOBy Jo HarperReportingExcessive outbreaks of seaweed are clogging up waters from the Caribbean to the Baltic. Now the algae is being harvested alongside farmed crops to create ingredients for cosmetics and food products.Mari Granström says it was her passion for scuba diving that opened her eyes to the continuing problem of toxic algae blooms in the Baltic Sea.The outbreaks occur when tiny cyanobacteria, also called blue-green algae, suddenly multiply rapidly, stretching out on top of the water for potentially kilometres.Also called eutrophication, it is a form of marine suffocation, and it is a significant environmental concern in the Baltic Sea. It can occur in 97% of the total area of the sea, according to official figures.The blooms impact on other marine life, by causing oxygen deficiency, reducing water quality, and blocking out light.Getty ImagesThe problem is caused by too many nutrients entering the water, typically nitrogen and phosphorus from artificial fertilisers. These are carried into the sea by the rivers of the surrounding countries – Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia and Sweden.While the use of such fertilisers has reduced in recent years, the Baltic Marine Environment Protection Commission, the intergovernmental organisation that aims to improve water quality in the sea, says “the effect of these measures has not yet been detected”.Some six years ago Ms Granström, a Finnish biochemist, determined to tackle the problem herself. She’d harvest the algae and use it to make ingredients for a host of products. In addition to cosmetics and human food, the algae extracts can be used in detergents, animal feed, packaging, and even as a replacement for plastic.This comes as there is a growing trend for seaweed to be harvested for such purposes, as a replacement to oil-based ingredients.ObO”I saw with my own eyes – or perhaps couldn’t see – how it was affecting the marine ecosystem, and decided to do something,” she says. “There was too much finger pointing and not enough action.”Ms Granström says she worked on the project as “a hobby for a long time”, before in 2019 setting up a company called Origin by Ocean (ObO). She is the chief executive.The business, which has attracted both commercial investment and European Union funds, is now continuing with a pilot production scheme ahead of aiming to be fully operational by 2025-26.ObO collects the algae off the coast of Finland, where it is sucked on to boats and then separated from the water. The firm is also importing invasive sargassum seaweed from the Dominican Republic in the Caribbean.ObOVast blooms of that algae have plagued that region for a number of years. “There are 25 million tonnes of sargassum blooming in the Caribbean every year,” says Ms Granström.”It stops people fishing and harms tourism. We are now buying several tonnes of sargassum from the Dominican Republic, and this volume will increase.”The company further sources unwanted seaweed from Portuguese and Spanish waters.ObO’s pilot processing is done at a facility in northern Sweden. It uses a patented biorefinery technology it calls “Nauvu” to separate the algae into numerous useable materials.These are then sold to food, cosmetics, textiles, packing and agricultural companies.Global TradeMore from the BBC’s series taking an international perspective on trade.To help grow the business ObO is working with one of its investors, Finnish chemicals and industrial group Kiilto. “If this can be successfully scaled up here, then ObO can replicate similar processes around the globe,” says Ville Solja, Kiilto’s chief business development officer.ObO already has plans to set up a refinery in the Dominican Republic.Across in Sweden, a separate business called Nordic Seafarm is showing just how versatile seaweed can be.”We make algae-based gin and beer, both locally produced,” says director Fredrik Gröndahl.Nordic Seafarm, which grows its own seaweed, is a commercial spin-off from Seafarm, a Swedish government-funded project that helps commercialise aquaculture research. “If this market [for seaweed] gets big, and we think it will, we are ready to scale up,” adds Prof Gröndahl, who is also project leader of Seafarm, and head of department for sustainable development, environmental science and engineering at the KTH Royal Institute of Technology in Stockholm.”Just imagine if Ikea asked for algae-based meatballs globally, which could happen.”Fredrik GröndahlProf Gröndahl also hopes that in the future algae will become a key ingredient in animal feed, to replace environmentally-damaging fish meal, which is common in pigs and poultry diets. “Algae is also cheaper than existing ingredients as there is no cost for feeding and irrigation.”Back at ObO, Ms Granström says the aim is for shoppers around the world to “play a part in cleaning up the Baltic Sea” by simply buying a number of consumer products.”We wanted to do something to help at both ends of the process, upstream and downstream, as it were – cleaning the seas, but also monetising a change in consumer behaviour.”
