- Biodegradable plastics produce methane gas on decomposition while using for landfill. Methane gas is a potential green house gas.
- Biodegradable plastics and bioplastics do not decompose readily. They need high temperature and may take some time to biodegrade. Also some bioplastics can leave behind toxic residues.
- Bioplastics and biodegradable plastics cannot be recycled easily because there are no dedicated waste streams for collection yet.
- Moreover bioplastics, biodegradable plastics and compostable are some terms which appear similar to general public but they are different categories of plastics. These have different times for degradation.
