Tea bags are usually made from a blend of paper and plastic, with plastic being used to heat seal the bags during manufacture. However, some companies are committed to producing tea bags that are plastic-free and biodegradable. Good Earth Tea is one such company that claims to produce tea bags that are biodegradable and eco-friendly. So, are Good Earth tea bags plastic-free?

What You'll Learn
Good Earth tea bags are made from PLA, a corn-starch-based material
Good Earth tea bags are designed to break down in industrial and municipal composting facilities, in certain controlled environments. These facilities control humidity and temperature to ensure the bags decompose within the time frame specified by global 'Compostable' labelling standards. If your community offers industrial composting services, you can dispose of used tea bags in your food waste or organics bin.
However, it is important to note that some studies have raised concerns about the potential health risks associated with exposure to PLAs. For example, a July 2024 study published in the Science of the Total Environment Journal examined the impact of PLA bioplastic tea bags on earthworms, finding negative effects on their health, growth, reproduction, and burrowing behaviour.
Good Earth tea bags are also Rainforest Alliance Certified, reflecting the company's dedication to sustainability and environmental issues. The company is always working to make every cup kinder to the planet, and their Sensorial Blends cartons are fully recyclable, with plant-based PLA tea bags and an updated BOPP inner film.
Overall, Good Earth tea bags made from PLA, a corn-starch-based material, offer a more environmentally friendly alternative to traditional plastic tea bags, but further research is needed to understand the potential health and environmental impacts of PLA biodegradation fully.

PLA tea bags may negatively impact earthworms
Good Earth tea bags are made from a corn-starch compound and are biodegradable. They can be put in your food waste bin at home or in your community's industrial composting services. However, a study by the University of Plymouth has shown that PLA-based tea bags, such as those used by Good Earth, did not fully deteriorate and could harm composting worms. The study examined the impacts of the tea bags on Eisenia fetida, a species of earthworm that plays a critical role in soil nutrient turnover. Results showed that exposure to different concentrations of tea bag discs led to up to 15% greater mortality, and some concentrations of PLA negatively impacted earthworm reproduction.
The study highlights the need for accurate disposal information on product packaging. While PLA-based tea bags are biodegradable, they require industrial composting facilities to fully decompose. Without proper disposal, the molecular structure of PLA-based tea bags can remain intact for several months in soil. This raises concerns about the potential for plastics to enter the soil when compost made from incompletely degraded PLA is added to gardens, which could impact garden wildlife and food plants.
The use of biodegradable plastics such as PLA in tea bags is becoming more common due to the plastic waste crisis. However, the study's authors emphasize the need for more evidence on the degradation and possible effects of these materials before their use becomes even more widespread. They also stress the importance of clear labelling to ensure consumers dispose of PLA tea bags correctly, preventing potential negative consequences on the environment.
The findings of this study have important implications for the understanding of the environmental impact of PLA-based tea bags and highlight the need for further research and collaboration between scientists, policymakers, and manufacturers to ensure proper disposal and prevent potential harm to ecosystems, including earthworms.

PLA tea bags are designed to break down in industrial composting facilities
Good Earth tea bags are made from PLA, a biodegradable plastic made from renewable resources like corn starch or sugarcane. While PLA tea bags are compostable, they require specific conditions typically found in industrial composting facilities. These facilities maintain high temperatures and controlled conditions that most home compost bins cannot achieve.
The tea brand recommends disposing of used tea bags in food waste or organics bins if the community offers industrial composting services. This ensures that the tea bags can properly break down into their natural components.
It is important to note that PLA tea bags should not be considered a completely eco-friendly alternative to traditional plastics. They rely on industrial composting and still have the potential for microplastic pollution. Additionally, there is limited infrastructure for industrial composting facilities worldwide, which can result in PLA tea bags ending up in landfills or the natural environment, where they may not degrade efficiently.
While Good Earth tea bags are designed to be biodegradable, the specific conditions required for their breakdown highlight the importance of proper disposal methods and the need for increased access to industrial composting facilities.

Most tea bags contain plastic
Good Earth tea bags are made from a corn-starch-based material called PLA that can decompose in industrial composting. Their Sensorial Blends tea bags are made from plant-based PLA, while their Sweet & Spicy tea bags are made from paper, cotton thread, and wood fibers with no staples or glue. Good Earth tea cartons are fully recyclable.
While PLA was introduced as a safer alternative to standard plastic, some studies have raised concerns about the toxicological implications of its biodegradation. For example, a July 2024 study published in the Science of the Total Environment Journal examined how polylactic acid (PLA) bioplastic tea bags deteriorate in environmental conditions and found that their breakdown negatively impacted earthworms, affecting their health, growth, reproduction, and burrowing behavior. Additionally, PLA has been designed to break down in industrial and municipal composting facilities, with specific controlled environments, and may not break down properly in home composting setups. Therefore, it is important to check with local councils before disposing of PLA tea bags in food waste bins.
