Bioplastics are not a single kind of polymer but rather a family of materials that can vary considerably from one another. There are three groups in the bioplastics family, each with its own individual characteristics:
- Biobased or partially biobased non-biodegradable plastics such as biobased PE, PP, or PET (so-called drop-ins) and biobased technical performance polymers such as PTT or TPC-ET
- Plastics that are both biobased and biodegradable, such as PLA and PHA or PBS
- Plastics that are based on fossil resources and are biodegradable, such as PBAT.
It is important to note, that the property of biodegradation does not depend on the resource basis of a material, but is linked to its chemical structure.
