Ukwethulwa kwento eluhlaza yepulasitiki ebonakalayo
Igama elithi "Biodegradable Plastics" libhekisela ohlotsheni lwamapulasitiki angahlangabezana nezidingo zokusebenzisa futhi alondoloze izakhiwo zawo ngesikhathi sokuphila kwaso eshalofini, kepha angadilizwa ezintweni ezinobungane bemvelo ngemuva kokusebenzisa ngaphansi kwezimo zemvelo zemvelo. Ngokwandisa ukukhetha kwezinto zokwenziwa kanye nenqubo yokukhiqiza, ipulasitiki ebonakalayo ingahle ibonwe ngezingcezwana futhi ekugcineni ibolile ngokuphelele ngaphansi kwesenzo sokukhanya, imvula kanye nezinyanga ezincane.
Izinzuzo zepulasitiki e-biodegradable
Ngesikhathi sesenzo se- "Ban Ban" Global "futhi sibhekene nesimo sokuqonda okuthuthukisiwe kwemvelo, ipulasitiki engathandeki ibonwa njengendawo ebambele yopulasitiki yendabuko. Ipulasitiki engathandeki ye-biodergradable iboshelwa kalula yimvelo yemvelo kunendabuko ye-polymer plastistics, futhi isebenza kakhulu, iyancipha futhi iphephile. Noma ngabe ipulasitiki engathandeki ingena endaweni yemvelo ngengozi, ngeke ibangele ukulimala okuningi futhi ingasiza ngokungaqondile ukuqoqa imfucuza ye-organic ngenkathi inciphisa umthelela wokungcola kwe-organic ekuvuseleleni imfucuza.
Ipulasitiki egcwele i-biodegramable inezinzuzo zayo ekusebenzeni, ukukwenza, ukulimazeka nokuphepha. Ngokuya ngokusebenza, ipulasitiki engathandeki ingafinyelela noma idlule ukusebenza kwamapulasitiki wendabuko emikhakheni ethile. Ngenkathi ngokwemibandela yokusebenziseka, ipulasitiki egcwele i-biodegramable inesicelo esifanayo nezindawo zokuhlanzeka kumapulasitiki wendabuko afanayo. Ngokwezinhlanhla, ipulasitiki egcwele i-biodeGradable ingadilizwa ngokushesha endaweni yemvelo (ama-microorganisms athile, izinga lokushisa kanye nomswakama) ngemuva kokusebenzisa futhi kube yimfucumfucu enobungozi noma i-angewona anobuthi emvelweni. Mayelana nokuphepha, izinto ezikhiqizwayo noma ezishiywe ezinqubweni zepulasitiki ze-biodegradable azinangozi emvelweni futhi azithinti ukusinda kwabantu nezinye izidalwa. Isithiyo esikhulu ekuthatheni indawo amapulasithi endabuko iqiniso lokuthi ipulasitiki engathandeki ibiza kakhulu ukukhiqiza kunabalingani babo abajwayelekile noma abasebenza kabusha. Ngenxa yalokhu, ipulasitiki egcwele i-biodegramadable inezinzuzo eziningi zokufaka izicelo ezifana nokupakishwa, ifilimu yezolimo, lapho isikhathi sokusebenzisa sinzima, ukululama nokuhlukanisa kunzima, izidingo zokusebenza ziphakeme.
Izikhwama zokupakisha ezingathandeki
Kulezi zinsuku, ukukhiqizwa kwePla kanye ne-Pbat kuvuthiwe ngokwengeziwe, futhi inani labo lokukhiqiza lisendaweni ephambili lepulasitiki, futhi njengoba izindleko ziwela emkhakheni wezokwelapha ophakeme kuya emakethe enkulu kanye nefilimu yezolimo ngokuzayo. Lepulasitiki engathandeki ye-biodegramable ingahle ibe ngenye indlela yendabuko yendabuko.
Izikhwama zepulasitiki ezithi ziyi-biodegradable zazisasebenza futhi zikwazi ukuthwala izitolo iminyaka emithathu ngemuva kokuvezwa imvelo yemvelo, kufundwe isifundo.
Ucwaningo okokuqala luhlolwe izikhwama ezikhohlisayo, izinhlobo ezimbili zesikhwama se-biodegradable kanye nezikhwama ezijwayelekile zokuthwala ngemuva kokuchayeka isikhathi eside olwandle, umoya nomhlaba. Azikho izikhwama ezibolile ngokuphelele kuzo zonke izindawo.
Isikhwama esikhokhwayo sibonakala sengathi siba ngcono kunesikhwama esibizwa ngokuthi yi-biodegradable bag. Isampula esikhwameni esikhohlakele sanyamalala ngokuphelele ngemuva kwezinyanga ezintathu endaweni yasolwandle kodwa abacwaningi bathi umsebenzi owengeziwe uyadingeka ukuthola ukuthi yimiphi imiphumela yokuphulwa kanye nokubheka noma yimiphi imiphumela yezemvelo.
Ngokusho kocwaningo, i-Asia kanye ne-Oceania Akhawunti yamaphesenti angama-25 wesidingo somhlaba wonke samapulasitiki angathandeki, anamathani angama-360,000 adliwe emhlabeni jikelele. I-China ibeka amaphesenti ayi-12 okufunwa komhlaba wonke kwamapulasitiki angenakubonwa. Njengamanje, ukusetshenziswa kwe-biodegradable plastics kusembalwa kakhulu, isabelo semakethe sisephansi kakhulu, ikakhulukazi amanani entengo e-biodegradable plastics aphezulu, ngakho-ke ukusebenza okuphelele akukuhle njenge-plastistics ejwayelekile. Kodwa-ke, kuzothatha isabelo esiningi emakethe njengoba abantu bayakwazi ukubaluleka kokusebenzisa izikhwama ze-biodegradable ukusindisa umhlaba. Ngokuzayo, ngocwaningo olwengeziwe lobuchwepheshe bePlastics ye-Biodegradable Plastics, izindleko zizophinde zincishiswe, futhi imakethe yayo yesicelo kulindeleke ukuthi yandise.
Ngakho-ke, izikhwama ze-biodegradable ziyindlela yokuqala yamakhasimende. Iphakethe eliphakeme ligxile ekukhuleni lolu hlobo lwezikhwama iminyaka futhi njalo ukuthola imibono emihle kusuka kubantu abaningi.
