-Recycling biopolymers with PET plastics contaminates the waste stream. Compost bioplastics in a warm environment with sufficient airflow.
+Gelatine-based bioplastics can be recasted by melting them in a pot with some water (but plastics with additives and fillers might not be reusable). Should not be recycled as part of PET-plastics waste: this causes contamination of the waste stream. Compost bioplastics in a warm environment with sufficient airflow.
