Ukuvela kwezindinganiso zomhlaba jikelele ze-GRS zokugaywa kabusha kwezikhwama zepulasitiki ezigaywe kabusha ukuze kutholwe ukwethembeka okuthile.Eminyakeni yamuva, umphumela we-greenhouse womhlaba uyaqhubeka uqina, imboni yepulasitiki kufanele iguqulwe ibe "umnotho wokubuyisela kabusha ipulasitiki", okusho ukuthi imboni yepulasitiki idinga ukuguqula imodeli yentuthuko, futhi kancane kancane ekuthuthukisweni komnotho oyindilinga.
Ngokusho kwedatha yezihloko zezezimali ibonisa ukuthi uma singakwazi ukwamukela ngokugcwele imodeli yomnotho oyindilinga, sikhuthaze umphakathi ukuthi uhambe kakhulu ekuphileni kwansuku zonke ukuze usebenzise izikhwama zepulasitiki ezigaywa kabusha, okungukuthi, udoti izikhwama zepulasitiki ezigaywe kabusha zibe yimikhiqizo emisha;noma izikhwama zepulasitiki ezibolayo, okungukuthi, izikhwama zepulasitiki ezilahlwayo azidingi ukuthi zidlule endaweni yokulahla imfucumfucu noma ekushiseni, zingase ziwohloke ngokuzenzakalelayo zibe amaphakheji epulasitiki kamanyolo wemvelo.I-biodegradable plastic bag material ngokuyinhloko i-PLA, eyenziwe ngesitashi sommbila, i-polymerized by fermentation, imikhiqizo yayo eqediwe ngaphezu kwe-biodegradable, kodwa futhi inamandla aphezulu, ukukhanya okuphezulu, ukumelana nokushisa okuhle, njll, kungahlanganiswa ngqo ekudleni.Uma sonke isibalo sabantu singagqugquzelwa ukuthi sisebenzise izikhwama zepulasitiki ezigaywa kabusha ezihlangabezana nezindinganiso kazwelonke ezifanele zezemvelo, lokhu ngeke nje kunciphise kakhulu ukusetshenziswa kwezikhwama zepulasitiki, kodwa futhi kuzonciphisa ukungcoliswa okumhlophe.Ngokuhamba kwesikhathi, kulindeleke ukuthi kugwenywe u-80% wepulasitiki engena olwandle ngo-2040, kuyilapho kunciphisa ukukhishwa kwegesi ebamba ukushisa yonyaka ngama-25% uma kuqhathaniswa nemodeli yezomnotho elandelanayo yamanje.
Namuhla, ngaphansi kwengcindezi yokukhula kwenani labantu kanye nokuqiniswa komphumela we-greenhouse, izinkampani ezinkulu kufanele zithathe ukudala umnotho oyindilinga, ohambisana nemvelo njengomgomo wazo omkhulu.
