1. Material Classification
Biobased Biodegradable Plastics: These biodegradable plastics are primarily derived from renewable biomass resources such as starch, sucrose, and cellulose, transformed into polymers through biological processes. For example, PLA (Polyactic Acid) is made from corn starch or sugarcane.
Petroleum-based Biodegradable Plastics: These materials are partially derived from fossil fuels but are specially designed to degrade under specific conditions. Examples include PBS (Polybutylene Succinate) and PBAT (Polybutylene Adipate Terephthalate).
2. Application Classification
Packaging Materials: Used for packaging biodegradable plastics such as shopping bags and food packaging boxes, these materials often have good transparency and printability.
Agricultural Films: Used for agricultural films such as soil coverage films and seeding trays, these materials need to have certain weather resistance and thermal insulation properties.
Disposable Dining Utensils: Used for disposable tableware and plates, these products can degrade relatively quickly under natural conditions after disposal.
3. Degradation Performance Classification
Compostable Biodegradable Plastics:  These plastics can completely degrade under industrial composting conditions, generating carbon dioxide, water, and biomass, suitable for organic recycling. For example, PLA and PBAT can fall into this category under certain conditions.
Non-Compostable Biodegradable Plastics: Although these plastics can degrade under natural conditions, they may not meet the requirements for industrial composting. For example, some modified starch plastics may fall into this category.
4. Other Classifications
Composite Materials: Composite biodegradable plastics combine the advantages of different materials, such as combining biomass plastics with natural fibers to improve the physical properties of the material and reduce environmental impact.
Functionalized Biodegradable Plastics: Functional biodegradable plastics enhance the performance of the material by adding specific additives (such as antimicrobial agents, antioxidants), suitable for more specialized applications.
