1. Isicelo emkhakheni wokuvikelwa kwemvelo
Ekuphenyweni kwemvelo yamanzi kwatholakala ukuthi imfucuza usuku nosuku, ngokuvamile ihlukaniswe inayiloni, i-polyethylene, i-polyester nokunye.Lezi zimfucumfucu azikwazi ukucekelwa phansi ngokuphelele endaweni yamanzi, futhi njengoba inani liba likhulu futhi likhulu, ukulimala kwabo kuyabonakala.Uma kusetshenziswa izinto zokuwohloka, zingahlehliswa zibe izinhlanganisela zamangqamuzana aphansi ngaphansi kwesenzo se-microbial secretory enzymes, bese kuba yi-carbon dioxide namanzi ngokusebenzisa i-microbial metabolism.
2. Iziqukathi zokudla kanye nezicelo zemboni yokupakisha
Izinto zokupakisha ezibolayo ngokuvamile zingama-polymer awonakaliswa engezwe efilimini ye-laminate noma axutshwe ngokuqondile nezinto eziwuketshezi ukuze enze ifilimu.Ezintweni zokupakisha, ucwaningo olwengeziwe luwukusetshenziswa kwesitashi, i-cellulose, i-chitin nezinye izinto ze-polymer zemvelo ngokwazo noma eziguqulelwe ezitsheni zokudla namafilimu okupakisha.Inkampani yaseBrithani i-PORVAIR ithuthukise izakhiwo zepulasitiki ze-polyurethane corn isitashi sezinto ezikhethekile, isivinini sokuwohloka, isitashi sengezwe inani elingama-50%, eliphefumulayo futhi lingavuthelwa libe yifilimu, lisetshenziswe kabanzi ekufakweni kokudla.
3. Isicelo kwezolimo
Izinto ezibolayo ezibolayo zisetshenziswa kakhulu kwezolimo njengendawo yokumboza izithombo zezolimo kanye neziqukathi zokukhula kwezitshalo.I-mulch yezolimo ithuthukiswe kabanzi futhi yasetshenziswa ekhaya naphesheya.I-biodegradable master batch egxilile equkethe i-N\P\K nezinye izinto zamakhemikhali yalungiswa yi-Beijing Plastics Research Institute isebenzisa i-polyethylene njengento eluhlaza eyisisekelo futhi yengeza i-photocatalyst ngokucekelwa phansi.Isetshenziswe ezindaweni eziningi zokulima futhi yazuza imiphumela emihle.
4. Esicelweni sezokwelapha
Lapho okokusebenza kuqeda umsebenzi wezokwelapha, ngesikhathi esithile kungenziwa i-hydrolyzed noma i-enzymolysis ibe ama-molecule amancane ukuze abambe iqhaza kumjikelezo ojwayelekile we-metabolic, ukuze amuncwa noma akhishwe umzimba womuntu.Izinto ezibolayo ezibolayo zisetshenziswe ekuhlinzweni kwemithambo, ukuhlinzwa kwamathambo, i-matrix yokukhululwa kwezidakamizwa ku-vivo, ama-absorbent sutures neminye imikhakha yezokwelapha.
