1.Isikhwama se-Biodegradation，Izikhwama ze-Biodegradation yizikhwama ezikwazi ukubola amagciwane noma ezinye izinto eziphilayo.Cishe izikhwama zepulasitiki eziyizigidi eziyizinkulungwane ezingu-500 kuya ku-1 trillion zisetshenziswa minyaka yonke. Izikhwama ze-Biodegradation yizikhwama ezikwazi ukubola amagciwane noma ezinye izinto eziphilayo.Cishe izikhwama zepulasitiki eziyizigidi eziyizinkulungwane ezingama-500 kuya ku-1 trillion zisetshenziswa minyaka yonke.
2. Hlukanisa phakathi kwe-"biodegradable" kanye "necompostable"
Ngokwejwayelekile, igama elithi biodegradable linencazelo ehlukile kune-compost.I-Biodegradable imane isho ukuthi izinto zingaboliswa amagciwane noma ezinye izinto eziphilayo, futhi "umquba" embonini yepulasitiki uchazwa ngokuthi amandla okubola endaweni ye-aerobic egcinwe ngaphansi kwezimo ezithile zokushisa ezilawulwayo kanye nomswakama.I-Compospost iyikhono lokubola emkhakheni we-biodecompose endaweni engaboli ne-carbon dioxide engaboli. amanzi, ama-inorganic compounds kanye ne-biomass ngenani elihambisanayo
Ukufakwa "kwezinto ezingaphili" akuhlanganisi umkhiqizo wokugcina ekuthathweni njengomquba noma umquba, okuyizinto eziphilayo kuphela.Eqinisweni, izinga le-xxx elidingekayo ukuze upulasitiki ubizwe ngomquba ngaphansi kwencazelo ye-ASTM ukuthi kufanele unyamalale ngesilinganiso esifanayo nenye into umuntu ayazi kakade ukuze enze umquba ngaphansi kwencazelo yendabuko. Izikhwama zepulasitiki zingenziwa nge-polymer yepulasitiki evamile (okungukuthi, i-polyethylene) noma i-polypropylene futhi ixutshwe nesithasiselo esibangela ukuwohloka kwe-polymer (i-polyethylene) bese ibola ngenxa ye-biodegradable.
3.Impahla yesikhwama esibolayo
eziqinile njengeziqinile futhi ezinokwethenjelwa njengezikhwama zendabuko (ikakhulukazi i-polyethylene).Izikhwama eziningi zenziwe ngephepha, izinto eziphilayo, noma i-polyhexanolactone. "Umphakathi ubona ukuthi i-biodegradable yinto ewumlingo," nakuba leli gama lisetshenziswa kakhulu, ngokusho kukaRamaniNarayan, unjiniyela wamakhemikhali e-East Lansing Michigan State University kanye nomeluleki wesayensi e-Institute for Biodegradable Plastics. "Leli okwamanje igama elisetshenziswa kakhulu futhi elisetshenziswa kabi esichazamazwini sethu.
4.Ukwenziwa kabusha kwezikhwama ezibolayo.
Imfucuza esezitshalweni ngokuvamile ingagaywa kabusha, kodwa kunzima ukuyihlela futhi igaywe kabusha ngemva kokusetshenziswa.Ama-polymers asekelwe ku-Bio angakwazi ukungcolisa ukugaywa kabusha kwamanye ama-polymers avamile.Ngenkathi abakhiqizi bepulasitiki e-aerobic biodegradable bethi izikhwama zabo ziyakwazi ukugaywa kabusha, ama-recyclers amaningi epulasitiki efilimu ngeke azamukele ngoba alukho ucwaningo lwesikhathi eside mayelana nokuba nokwenzeka kwemikhiqizo ye-Plasticable equkethe lezi zinto ezigaywa kabusha ze-Plastic. (BPI) ithe ukwakheka kwezithasiselo kumafilimu ane-oxidized kuyahluka kakhulu, okwethula ukuhlukahluka okwengeziwe kwinqubo yokugaywa kabusha.
