What does the number 7 for recycling mean on products made from corn?
A wide variety of products that do not fall into recycling categories 1-6 have been lumped into recycling category 7, including products made of PLA that are compostable. In recent years, it was found that many plastics in recycling category 7 were made with Polycarbonate plastic and leached Bisphenol A. Bisphenol A has been linked to a number of health hazards. Products made from PLA are 100% free of Bisphenol A.
