29 May 2024 --- Tea bags manufactured using plastic alternatives might not biodegrade and could harm terrestrial species, according to a new study. The study’s authors highlight the need for accurate disposal information to be displayed on product packaging, differentiating between industrial and home compostability. The research looked at commonly available tea bags from three different compositions of polylactic acid (PLA), which is derived from sources such as cornstarch or sugar cane. The tea bags were buried in soil for seven months and a range of techniques were then used to assess if they had deteriorated.
