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 isho nje ukuthi izinto zingaboliswa amagciwane noma ezinye izinto eziphilayo, futhi "umquba" embonini yepulasitiki uchazwa ngokuthi amandla okubola endaweni ye-aerobic egcinwe endaweni ethile. izinga lokushisa elilawulwayo kanye nezimo zomswakama.I-Compospost ikhono lokubola endaweni yomquba, okwenza izinto ezingabonakali zingabonakali futhi zibole zibe yi-carbon dioxide, amanzi, izinhlanganisela ze-inorganic kanye ne-biomass ngenani elihambisanayo
Ukufakwa "kwezinto ezingaphili" akubandakanyi umkhiqizo wokugcina ekuthathweni njengomquba noma umquba, okuyizinto eziphilayo kuphela. Eqinisweni, izinga le-xxx elidingekayo ukuze ipulasitiki ibizwe ngomquba ngaphansi kwencazelo ye-ASTM ukuthi kufanele inyamalale ngesikhathi esifanayo. ukukala njengokunye umuntu asekwazi ukwenza 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 engumlingo," nakuba leli gama lisetshenziswa kakhulu, ngokusho kukaRamaniNarayan, unjiniyela wamakhemikhali e-East Lansing Michigan State University kanye nomeluleki wesayensi e-Institute for Biodegradable Plastics." Lena okwamanje isetshenziswa kakhulu. kanye namagama asetshenziswe kabi kusichazamazwi sethu.E-Greater Pacific Waste Area, ipulasitiki ebolayo ihlukana ibe izingcezu ezincane ezingangena kalula eketangeni lokudla ngokusetshenziswa.
4.Ukwenziwa kabusha kwezikhwama ezibolayo.
Imfucuza esezitshalweni ngokuvamile ingabuye igaywe kabusha, kodwa kunzima ukuyihlela futhi igaywe kabusha ngemva kokusetshenziswa.Ama-polymer asekelwe ku-Bio angakwazi ukungcolisa ukugaywa kabusha kwamanye ama-polymers avamile.Ngenkathi abakhiqizi bepulasitiki e-aerobic biodegradable bathi izikhwama zabo ziyakwazi ukuphinda zisetshenziswe, amafilimu amaningi epulasitiki abasebenzisa kabusha izinto ngeke bakwamukele ngoba alukho ucwaningo lwesikhathi eside mayelana nokuba nokwenzeka kwemikhiqizo egaywa kabusha equkethe lezi zithako.Ngaphezu kwalokho, i-Institute for Biodegradable Plastics (BPI) ithe ukwakheka kwezithasiselo kumafilimu ane-oxidized kuyahlukahluka kakhulu, okwethula ukuhlukahluka okwengeziwe. ohlelweni lokugaywa kabusha.
