Iplastiki ye-Biodegradable ibhekiselele kwizinto ezinokuthi zithotywe zibe zizinto ezinobunzima obuphantsi be-molecular yi-microorganisms ngokwazo okanye i-secretions ye-microorganisms phantsi kweemeko ezithile. Ulawulo lokutya kunye neziyobisi lwase-US lumisela ukuba, ngaphandle kweeplastiki ezinokonakala kunye neeplastiki ezincinci ezingonakaliswa ngamanzi ezinokuthi zisetyenziswe ekupakisheni ukutya, ezinye ezinje ngeeplastiki ezithatha ifoto okanye iiplastiki ezilula kunye ne-biodegradable ziyasilela ukuhlangabezana nemimiselo njengezinto zokupakisha ukutya.
