What is plastic made in China and rice made in Japan?

Plastics in China are usually made from fossil fuels such as petroleum. Plastic is a synthetic material, usually made of polymers and other compounds. In China, most plastic products are made of fossil fuels such as oil and natural gas. These fossil fuels react chemically in the process of processing to produce different polymers, and then they are made into various plastic products through processing, molding and other processes. In Japan, bioplastics made of biomass materials, such as rice, can replace traditional plastics to some extent, reduce environmental pollution and have high environmental protection. However, the production cost of bioplastics is relatively high, and large-scale production needs further technical and economic support.
