Eminyakeni yamuva nje, njengoba ukuqwashisa jikelele kokuvikelwa kwemvelo sekukhulile, udaba lokungcoliswa kwepulasitiki seluvelele ngokwengeziwe. Ukubhekana nale nselelo, izinkampani eziningi nezikhungo zokucwaninga zigxile ekuthuthukiseniIzikhwama zokupakisha ezingathandeki. Lezi zinto zokupakisha ezintsha azikunciphisi umthelela omubi emvelweni kodwa futhi zinikeza indlela entsha yokuxazulula inkinga yokulawulwa kwemfucuza yomhlaba.
Yiziphi izikhwama zokupakisha ezingathandeki?
Izikhwama zokupakisha ezingathandekiziyizinto zokwakha ezingabola ngezinto ezingenabungozi njenge-carbon dioxide, amanzi, kanye ne-biomass ngaphansi kwezimo zemvelo (njengokukhanya kwelanga, izinga lokushisa, umswakama, kanye nama-microorganisms). Uma kuqhathaniswa nezikhwama zepulasitiki zendabuko, inzuzo enkulu yezikhwama ze-biodegradable ngumthelela wazo wezemvelo, ukunciphisa ukungcola okubangelwa ukugcwala komhlaba nokushiswa.
Ukukhula okusheshayo esifungweni semakethe
Njengoba abathengi bafuna imikhiqizo eminingi e-eco-friendly, abathengisi abaningi kanye nezinkampani zokudla sebeqalile ukwamukela izikhwama zokupakisha ezingathandeki. Imikhiqizo eyaziwa emhlabeni jikelele efana ne-IKEA nama-Starbucks asevele ehola indlela yokuqhakambisa lezi zixazululo zokupakisha ezinobungane bemvelo. Ngasikhathi sinye, ohulumeni abahlukahlukene bathumele izinqubomgomo zokukhuthaza amabhizinisi nabathengi ukuthi basebenzise izinto ze-biodegradable. Isibonelo, "isu leplastiki elithi" yepulasitiki "ngokusobala lifuna ukuncishiswa kwamapulasitiki asetshenziswa ngakunye eminyakeni ezayo.
Ukuthuthuka Nezinselelo Zobuchwepheshe
Njengamanje, izinto zokusetshenziswa eziphambili zokukhiqiza izikhwama zokupakisha ezingathandeki zifaka izinto zokwakha isitashi, i-PLA (polylactic acid), ne-PA (polyhydroxyalkates). Kodwa-ke, naphezu kwentuthuko esheshayo yezobuchwepheshe, izikhwama ze-biodegradable zisabhekene nezinselelo ezithile. Okokuqala, izindleko zabo zokukhiqiza ziphakeme kakhulu, zikhawulela ukwamukelwa okukhulu. Okwesibili, eminye imikhiqizo isadinga izimo ezithile zokubola okufanele futhi kungenzeka ingahlali ngokugcwele ezindaweni ezijwayelekile.
Umbono wesikhathi esizayo
Naphezu kwezinselelo zezobuchwepheshe nezobuchwepheshe, ikusasa lezikhwama zokupakisha ezingathandeki zihlala zithembisa. Ngokukhuphuka kwemali ocwaningweni nasekuthuthukisweni, kanye nesikali sokukhiqiza esandisiwe, ukufakwa okubhalwe phansi kwe-bioderlowable kulindeleke ukuthi kube kubize kakhulu. Ngaphezu kwalokho, njengoba imithethonqubo yezemvelo yomhlaba iba nzima kakhulu, ukusetshenziswa kwezinto ezisetshenziswayo ze-bioderhradable kuzoba yindlela ebalulekile yezinkampani ukufeza izibopho zazo zomphakathi futhi zithuthukise isithombe sazo somkhiqizo.
Sekukonke, izikhwama zokupakisha ezingathandeki ziba ngumdlali osemqoka kakhulu emakethe ngezindlela zepulasitiki, hhayi nje ukuthuthukisa ukuthuthukiswa komkhakha wokuvikela imvelo kodwa futhi kufaka isandla entuthulweni yomhlaba wonke.
