7 Best Sustainable Reusable Coffee Cups

Every year, we throw away over 50 billion single-use coffee cups in the United States alone, most of which are coated in plastic. While single-use coffee cups are convenient, when we’re done with them, many of them go directly to landfills and the ocean, contributing to environmental degradation, contamination, and the spreading of disease. 

One of the most effective ways to reduce this type of waste is to use reusable coffee cups. In fact, you can begin making a positive environmental difference after using a reusable cup as few as 7 times!

This article will help you choose the best sustainable reusable coffee cup to meet your needs. Keep reading to learn how we made our picks, or jump straight to our product recommendations.

Background Information: Cups: Single Use (Disposable) vs. Reusable – An Honest Comparison

How We Picked the Most Sustainable Reusable Coffee Cups

Using any reusable cup is more eco-friendly than throwing out a coffee cup every day. But not all reusable coffee cups are made equal, as some are more eco-friendly than others. Here are the other factors we considered in our research to make sure we picked the very best sustainable reusable coffee cups.

Health & Safety 

Some reusable coffee cups on the market, particularly those made of plastic, contain toxic chemicals that can leach into your drink, with the potential to cause health problems. All of the products we chose are free of toxic chemicals that may be present in some conventional reusable cups, including:

Materials 

We chose products made from lower-impact sustainable materials, including:

  • Plant-based materials, like rice husks
  • Recycled or upcycled materials
  • Biodegradable materials
  • Stainless steel
  • Glass

All of these reusable coffee cup materials have a lower environmental impact than disposable plastic.

Quality

We’ve searched for cups that are durable and well-made. For example, we made sure that these cups are built to last and that none of them burn your hands, or it can keep your coffee warm for a period of time, or it is featured with a spill-free lid so you’d be able to bring your coffee on your next camping or hiking adventure.

Compatibility With Your Favorite Barista

We’ve also checked for cups that have size and quality that are accepted by most major coffee shops, including Starbucks. 

Manufacturer’s Ethical & Sustainable Practices

Finally, we’ve reviewed each manufacturer’s adherence to other sustainable and ethical standards. For example, we reviewed whether the manufacturer ensures fair wages and safe working conditions, and if they engage in other sustainable practices such as relying on renewable energy or using sustainable packaging.

Sustainable Reusable Coffee Cups

Around the world, the majority of single-use coffee cups are not recycled. While some coffee shops are investing in cups designed to be recycled or composted, the most eco-friendly option is to simply use a reusable coffee cup for your daily morning – or afternoon – coffee. Here are our picks for the best sustainable reusable coffee cups.

KeepCup glass reusable coffee cups are made of ultra-durable tempered glass, and feature a cork band for a secure grip, making them one of the best plastic coffee cup alternatives. Glass is an extremely sustainable material, as it can be sourced naturally from sand, lime stones, and soda ash, or be recycled from pre-used glass pieces. Glass is fully recyclable.

The cork band around the middle of this glass reusable coffee cup is built perfectly to help you keep a strong grip on the cup while also protecting your hand from getting burnt by hot coffee.

KeepCups are BPA-free, BPS-free, and phthalates-free.

Downsides: Cleaning the exterior of the cup might be a little tricky. The cork band is fragile when removed from the cup, especially when soaked with water, so it can crack if you’re not careful. To avoid this, hand-wash the cup carefully without taking the cork band off.

Ecoffee reusable bamboo coffee cups are made of natural bamboo fiber, corn starch, and plant-based resin, with a food-grade silicone lid and sleeves. Bamboo is very sustainable because it grows quickly with less water usage and doesn’t need to be uprooted when harvested, allowing it to keep storing carbon even as it’s used.

This cup’s silicone lid is tight and secure, preventing spillage. Reviews also note that the silicone band is excellent for maintaining your grip and protecting your hands from the heat of the coffee. The Ecoffee cup comes in 100 different trendy styles, providing a variety of design options depending on your style, from Van Gogh inspired patterns to solid colors.

Since its launch in 2014, Ecoffee Cup and its customers have prevented 10 million single-use coffee cups from entering landfills and the ocean.

Ecoffee Bamboo cups are BPA-free, BPS-free, and phthalate-free. Although the majority of the components are natural, the cup does include a small amount of melamine as a glue, which is perfectly safe as long as you avoid microwaving the cup. 

Downsides: Since the cup is made mostly of natural materials like bamboo fiber, it doesn’t handle rapid temperature changes well, and may break if you pour boiling water into the cup after storing it into a cold environment. To avoid breakage, check out the proper care instructions on the Ecoffee Cup website. We also noticed that the Ecoffee Cup only keeps your coffee warm for about 40 minutes, which isn’t quite as long as an insulated thermos cup.

Huskup eco-friendly coffee cups are made from non-GMO rice husks (and reusable silicone for the lid and sleeves). Using rice husks as an alternative to plastic not only reduces plastic waste, but also diverts agricultural waste like rice husks from entering landfills and being burned. This helps to reduce carbon emissions and avoids the need for producing new raw materials.

Since the Huskup cups are made from rice husks, they don’t have a plastic or metal taste or odor like some conventional reusable cups. The Huskup cups are also totally microwave safe and biodegradable; in fact, the Huskup cups have been certified to European Composability Standards (EN13432) on the following criteria:

  • Biodegradation – Products will biodegrade completely 6 months after disposal.
  • Disintegration – 90% of the cup will disintegrate after just 12 weeks of disposal.
  • Eco-toxicity – The cup does not cause any environmental harm once disposed of.
  • Heavy metal contents – The cup doesn’t contain dangerous amounts of heavy metals.

Huskup has collaborated with several independent artists to make incredibly fun designs. These coffee cups are available in beautiful patterns like waves and sunflowers, themes like Game of Thrones and Harry Potter, and solid colors. 

Huskup also has several initiatives that directly help the environment. For example, The Huskup Forest initiative aims to plant 10,000 trees, one for every two cups purchased. Huskup’s Common Seas initiative supports the island of Paros in Greece in becoming the first island in the Mediterranean to stop using single-use plastic.

Huskups are BPA-free and dishwasher-safe.

Downside: Since the cup does not have thermal insulation, it can only maintain warm temperatures for around an hour.

Another thing we love about BioGo cups is that they are anti-scald, so you don’t have to worry about getting your hands too hot even without a cup sleeve.

BioGo has incorporated other environmental practices into their company culture and values. For example, the company has vowed to plant a tree for every cup sold. This not only saves 4,000 single-use cups for every BioGo cup produced, but it also directly contributes to reforestation efforts.

BioGo cups are BPA-free and toxin-free. These cups also come in different colors, such as mint, green, pink, gray, yellow, orange, and black.

The cup’s interior is insulated and can keep your coffee or other hot beverage warm for 60 to 90 minutes. We also love that the lid is push-to-open/close and offers a 360-degree drinking angle. It’s also tight and secure, making it 100% leak proof.
