Muva nje, intatheli ifunde ku-China Paper Association, ngokusho kwe-China Paper Association yonyaka wohlelo lokubuyekezwa okujwayelekile, le nhlangano isiqedile "ayikho inkomishi yephepha lepulasitiki (okubandakanya nokungabikho kwepulasitiki.izinkomishi zephepha ezingaboli)” okusalungiswa okujwayelekile kweqembu, manje ukuze umphakathi ucele imibono.
Iniizinkomishi zephepha ezivundisiweayikho inkomishi yephepha lepulasitiki? Uyini umehluko phakathi kwayo kanye ne-aizinkomishi zephepha ezenzelwe wena?
Abathengi abaningi bangase bangazi ukuthi izinkomishi zabo zephepha ezilahlwayo ezivamile zibonakala zivumelana kakhulu nemvelo, kodwa zingaphansi kwesigaba esingasebenziseki kabusha ekuhlukaniseni udoti.
“Izinkomishi zephepha zinqunyelwe umkhiqizo wephepha akuzona izici ezingangenwa amanzi, ukuze kuvinjwe ukubhoboza kwamanzi, ifilimu ehlanganiswe ngepulasitiki ye-polyethylene (PE) izokwengezwa ezinkomishini zephepha.” Ngokwebhizinisi lokupakisha lepulasitiki e-Haikou, e-Hainan, inkomishi yesiphuzo esishisayo izombozwa enkomishini, futhi isiphuzo esibandayo sizombozwa ngaphakathi nangaphandle kwenkomishi. Akulula ukuhlukana nephepha ohlelweni lokugaywa kabusha, ngakho-ke lihlukaniswe libe yimfucumfucu engaphenduki.
Kuyaqondakala ukuthi kusukela ngoDisemba 1, "ipulasitiki yokuvinjelwa" yaseHainan ebanzi, ifakwe esifundazweni saseHainan evinjelwe ukukhiqizwa kanye nokusetshenziswa kokuthengisa kohlu lwemikhiqizo yepulasitiki engaboli (iqoqo lokuqala) lemikhiqizo yepulasitiki izovimbela ukukhiqizwa nokuthengisa, ucwaningo lwenkampani kanye nentuthuko ekhiqizwe ngokugcotshwa kwamanzi esikhundleni senkomishi yephepha ye-polyethylene yendabuko ngaphandle kwenkomishi yephepha lepulasitiki, qaphela yonke into.
Ukuthi inkomishi yephepha lepulasitiki ekhiqizwa inkampani ifanelekile yini izinga. Uhlaka lwenkomishi yephepha lepulasitiki (okuhlanganisa nephepha lenkomishi yephepha lepulasitiki) luthi "izinkomishi zephepha lesisekelo kufanele zihlangabezane nezidingo ze-QB / T 4032. Uwoyela omhlophe uzohlangabezana nezidingo ze-GB 1886.215. Uyinki nokunamathela kuzohambisana nezindinganiso ezifanele. Izithasiselo ezisetshenziswa ezinkomishini zephepha, uwoyela omhlophe, uyinki, izinamathiselo ezisekelwe ku-8 ze-GB kufanele zihlangabezane nezidingo ezisekelwe ku-8 ze-GB."9
Ngokwesethulo, inkomishi yephepha evamile elahlwayo ngoba iqukethe i-polyethylene, empeleni ayikwazi ukugaywa kabusha, hhayi uhlobo lokuvikela imvelo izidingo zansuku zonke. Nakuba izinkomishi zephepha ezihlanganiswe nge-PLA zingabola ngokuphelele, izindleko zempahla eluhlaza ziholela emananini aphezulu emikhiqizo eqediwe. Ngokukhuthazwa "kokuvinjelwa kwezikhwama zepulasitiki", azikho izinkomishi zephepha zepulasitiki ezaba khona.
Kuyaqondakala ukuthi "ukuvinjelwa kwepulasitiki" kuqukethe i-polyethylene, i-polypropylene, i-polystyrene, i-polyvinyl chloride, i-polyvinyl chloride-vinyl acetate copolymer, i-polyethylene terephthalate nezinye izinto ze-polymer ezingaboli zemikhiqizo yepulasitiki esetshenziswa kanye.
“Kumkhiqizi wenkomishi yephepha, uma engathola into eshibhile ehlangabezana nezidingo zokusebenza zenkomishi yephepha futhi engeyona enye yezinto eziyisithupha ezingaboli, khona-ke inkomishi yakhe yephepha ingabizwa ngokuthi izinkomishi zephepha zepulasitiki bese ifakwa emakethe.” Ochwepheshe batshele izintatheli.
Ngaphezu kwalokho, kungase kuthulwe ngokuya ngokuthi i-coating is degradable ngeke ibe khona inkomishi yephepha lepulasitiki cishe ihlukaniswe izigaba ezimbili, okungukuthi "inkomishi yephepha yokunamathisela engaboli" kanye "nenkomishi yephepha ebolile". Okwangaphambili, inqobo nje uma izithako zokumboza zingafakiwe ohlwini lwamanje lwezinto ezingaboli, zisengalethwa ngokusemthethweni emakethe.
Njengoba ubuchwepheshe buthuthuka, ithemba liwukuthi izinto zokwakha ezingabizi kakhulu zizotholakala, kusho abantu.
