What You'll Learn
Rishi tea bags are made from polylactic acid (PLA)
Consumers are increasingly aware of what they put into their bodies, and the last thing anyone wants is to worry about plastic leaching into their tea. Many mainstream tea bags contain plastic that can leak harmful plasticizers into your brew. However, Rishi Tea is committed to the health and well-being of its customers and uses plant-based tea bags made from polylactic acid (PLA).
Rishi Tea's PLA tea bags are free from plastics and petroleum. PLA is an inert, DNA-free material produced by breaking down starches found in plant sources like corn and sugarcane. This process eliminates all plant DNA, making the tea bags hypoallergenic and allergen-free. Unlike tea bags made from petroleum-based plastics, PLA will not leak harmful plasticizers into your tea.
Rishi Tea worked with an independent lab in Houston to test its PLA tea bags for safety. The lab used Gas Chromatography Mass Spectrometry (GC-MS) to analyze the chemical composition of PLA in its entirety. The testing method had a detectable limit of 2-3 ppm for the phthalates searched for, and none were detected, indicating that the PLA mesh used in Rishi Tea bags is completely BPA-free and phthalate-free.
Rishi Tea's PLA tea bags are also designed to facilitate biodegradability. The tea bags have a cotton string and printed-paper tag, with no glues, staples, or metals. The material is attached to the PLA mesh using ultrasonic+ high-heat vibrational energy. This makes Rishi Tea bags a safer and more environmentally friendly option for consumers.

PLA is made from corn and sugarcane starch
Rishi Tea is committed to the health and well-being of its customers. Its tea bags are made from a plant-based material called polylactic acid (PLA), which is produced by breaking down starches found in plant sources. PLA is not derived from petroleum and does not leak harmful plasticizers into tea. It is an inert, DNA-free material that is hypoallergenic and allergen-free.
PLA is a biodegradable plastic made from renewable sources such as corn or sugarcane starch, unlike traditional plastics derived from petroleum. It breaks down in composting facilities, reducing long-term waste. PLA production is more sustainable than traditional plastics, using plant-based materials and emitting less carbon. It is made from starch-rich crops like corn, sugarcane, or cassava. These renewable plants provide the glucose needed to produce lactic acid, the building block of PLA.
The process of making PLA from corn or sugarcane starch begins by isolating starch from the crops using a method called wet milling. In this step, kernels or stalks are soaked and ground to separate starch from fibre and protein. The starch then undergoes hydrolysis, a reaction with water and enzymes, to break it down into simple sugars such as glucose. The glucose is then fermented by beneficial microorganisms like Lactobacillus species.
PLA is used in various applications, including biodegradable packaging and shopping bags. It can be blended with other polymers to create a range of products with different properties. For example, it can be combined with starch to create biodegradable food packaging that provides an excellent gas barrier.

PLA is not derived from petroleum
Polylactic acid, or polylactide (PLA), is a thermoplastic polyester with backbone formula (C3H4O2)n or [–C(CH3)HC(=O)O–]n. It is produced by the condensation of lactic acid C(CH3)(OH)HCOOH with the loss of water. PLA is derived from renewable resources, particularly sugar and starch, and not from petroleum. It is a popular material due to its ability to be economically produced from these renewable resources.
Rishi Tea is committed to the health and well-being of its customers and uses plant-based PLA for its tea bags. The company has refuted claims that its silky tea bags contain petroleum-based plastic or nylon. To set the record straight, Rishi Tea worked with an independent lab in Houston to test its PLA tea bag materials. The lab used Gas Chromatography Mass Spectrometry (GC-MS) to analyze the chemical composition of PLA and found that it was completely BPA-free and phthalate-free.
PLA is an inert, DNA-free material produced by breaking down starches found in plant sources. This process removes all plant DNA, making PLA hypoallergenic and allergen-free. It is also biodegradable, with the main cause of its degradation being the attack of polymers by external elements. However, exposing PLA to water for a long period is necessary to initiate the hydrolysis process.
Rishi Tea's organic biodegradable, plant-based sachets are made from PLA and are free from plastics and petroleum. The company sources this material to provide its customers with the safest and most delicious cup of tea.

PLA is biodegradable
Rishi tea bags are made from a plant-based material called polylactic acid (PLA). This material is biodegradable and does not contain plastics or petroleum. The tea bags are attached to a cotton string and printed-paper tag, which are also biodegradable materials.
PLA is a bioplastic that can break down under specific conditions. However, it is important to note that PLA is not biodegradable in all environments. It requires industrial composting conditions or anaerobic digestion for biodegradation to occur. This means that PLA waste often ends up in landfills, where it can contribute to environmental challenges. To address this issue, some companies offer recycling services for PLA waste, and there are also creative solutions for upcycling PLA waste into new products.
The biodegradability of PLA is a complex issue. While it is true that PLA can break down, the process is slow and selective, occurring primarily under controlled conditions. This limits the practical biodegradability of PLA for most users. In addition, while PLA may be a more environmentally friendly alternative to traditional plastics, it is not a perfect solution. It still contributes to landfill waste and has been associated with the issue of microplastics.
Despite the challenges and limitations of PLA biodegradability, some companies are committed to sustainability and transparency in their use of PLA. For example, Rishi Tea prioritizes the health and well-being of its customers by using PLA tea bags that are free from plastics and potential contaminants. The company has also provided laboratory results to support the safety and biodegradability of their tea bags.
In summary, PLA is biodegradable under specific conditions, such as industrial composting and anaerobic digestion. However, the limited accessibility of these specialized setups means that PLA waste often ends up in landfills. To address this issue, recycling and upcycling initiatives offer viable solutions for diverting PLA waste from landfills. While PLA may not be the perfect solution to plastic waste, it is still a more eco-friendly alternative, and some companies are working to address its limitations.

Other tea bags are made from plastic
While Rishi tea bags are free from plastics and petroleum, many other tea bags on the market are made from plastic. These tea bags are usually sealed with plastic or are made from nylon or PET plastic. Even paper tea bags often have plastic fibres in the sealant and an unsettling substance called epichlorohydrin to stop them from bursting.
Plastic tea bags are a concern because they are subjected to high temperatures during the brewing process. This means that the plastic is more likely to melt and leach chemicals into the drink. The type of plastic most often used to seal tea bags is polypropylene, which is marked with a recycle number 5. While this is considered a safer plastic than some others, it is still not recommended that it be heated.
In addition to the health concerns, there are also environmental implications to using plastic tea bags. Plastic tea bags can take hundreds of years to decompose in nature and may fragment into microplastic particles. These microplastics can then be ingested by humans and other animals, with unknown health consequences. Even if tea drinkers dispose of their plastic tea bags in the trash instead of composting them, they are still contributing to the plastic pollution problem.
Some popular brands in the UK, such as PG Tips and Yorkshire, are working on eliminating plastic from their tea bags. In the meantime, consumers concerned about plastic in their tea can switch to loose leaf tea, instant tea, or cloth-based tea bags. They can also contact tea companies directly to inquire about the materials used in their tea bags.
