If plastic is a renewable resource and is not made of petroleum, the culprit of global warming, it would be great, and this requirement sounds a bit harsh. However, scientists have invented a new environmentally degradable plastic product made of bacteria, which is an improvement of butyrate. Butyrate is a new energy source made from a variety of bacteria through natural biological fermentation.
The special feature of this plastic is that although it is made of bacteria, it is very similar to synthetic polypropylene and can be completely degraded. It is less flexible than traditional plastics made from petroleum, but can be used in packaging, agriculture and biomedical products.

Liquid wood
“Liquid wood” is a promising new bioplastic, also known as “biopolymer”. This material looks, feels, and looks very much like plastic, but it is a bit different from traditional plastics, which are degradable. "Liquid wood" is made of lignin extracted from pulp and is a highly plastic composite material that is strong and non-toxic. The "liquid wood" production process is to first mix the paper mill's by-product lignin with water and then manufacture it under high temperature and high pressure. “Liquid wood” is an excellent alternative to plastics. German researchers have used this material to make a lot of products, including toys, golf tees, and even high-fidelity speakers.
Since this material is made of wood, it can also be recycled like wood, or broken down into small pieces as a filling, or burned directly.
