The most common type of environmentally friendly plastics in the market is plastics made by using recycled materials. It can be divided into pre-consumer/post-consumer (PCR), which regenerates daily waste plastics into environmentally friendly materials by recycling materials.

Daily waste plastics are also post-consumer (PCR) plastics. The above chart  shows that the performance of the plastic material itself does not change much after use, and then it is recycled and classified and reprocessed into plastic products by appropriate methods before reuse.

Bio-based plastics are plastics derived from renewable biomass sources, such as vegetable oils, corn starch, pea starch or microbiota. Biodegradable bioplastics can decompose in anaerobic or aerobic environments, depending on how they are made. Bioplastics can be composed of a variety of materials, including: starch, cellulose or other biopolymers. Some common applications of bioplastics are packaging materials, tableware, food packaging and insulation ( Source from Wikipedia).

Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three.

While the words "bioplastic" and "biodegradable plastic" are similar, they are not synonymous. Not all bioplastics (plastics derived partly or entirely from biomass) are biodegradable ( Source from Wikipedia)
