Biodegradable plastics refer to a kind of plastic that is degraded by natural microorganisms such as bacteria, fungi and algae. The ideal biodegradable plastic is a kind of polymer material with excellent performance, can be completely decomposed by environmental microorganisms after waste, and eventually become an integral part of the carbon cycle in nature by inorganization. Biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyesters, polylactic acid, starch/polyvinyl alcohol and so on.
The main target markets of biodegradable plastics are plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the increasing awareness of environmental protection, people are willing to use new biodegradable materials with a slightly higher price to protect the environment. Enhanced awareness of environmental protection has brought tremendous opportunities for the development of biodegradable new materials industry. Recycled plastics refer to a kind of waste plastics that can be recycled and reused through a certain recycling process.
Waste plastics are mainly plastic film, plastic silk and knitted goods, foam plastics, plastic packaging boxes and containers, daily plastic products, plastic bags and agricultural films. After manual screening and classification, waste plastics are subjected to such processes as crushing, granulation and modification.
All kinds of transparent and opaque plastic particles are transformed, then classified according to the phase, and finally become reusable recycled materials. Biodegradable materials and recycled materials can be classified as environmentally friendly materials. With the increasing awareness of environmental protection, the industry of environmentally friendly materials has brought tremendous opportunities for development.
