Ungcoliseko lweplastiki lubeka isoyikiso esimandla kokusingqongileyo, ngaphezulu kwe-9 yeebhiliyoni zeetoni zeplastiki eziveliswe ukusukela ngoo-1950, kunye ne-8.3 yezigidi zeetoni eziphela elwandle ngonyaka. Ngaphandle kweenzame zehlabathi, yi-9% kuphela yeplastiki ephinda isetyenziswe, ishiya uninzi lungcolise i-ecosystem yethu okanye sihlale kwindawo yokulahla inkunkuma kangangeenkulungwane.
Enye yezona zinto zinegalelo kule ngxaki kukuxhaphaka kwezixhobo zeplastiki ezisetyenziswa kanye njengeengxowa zeplastiki. Ezi ngxowa, zisetyenziselwa umlinganiselo wemizuzu nje eli-12, ziqhubela phambili ukuthembela kwethu kwiiplastiki ezilahlwayo. Inkqubo yabo yokubola ingathatha iminyaka engama-500, ikhupha i-microplastics eyingozi kwindawo.
Nangona kunjalo, phakathi kwale mingeni, iiplastiki ezinokubola zibonelela ngesisombululo esithembisayo. Yenziwe ukusuka kwi-20% okanye ngaphezulu kwezinto ezivuselelekayo, i-bio-plastiki inika ithuba lokunciphisa ukuxhomekeka kwethu kumafutha e-fossil kunye nokunciphisa i-carbon footprint yethu. I-PLA, evela kwimithombo yezityalo efana ne-corn starch, kunye ne-PHA, eveliswa yi-microorganisms, zimbini iindidi eziphambili ze-bio-plastiki ezinezicelo ezininzi.
Ngelixa iiplastikhi ezinokonakala ngezinto eziphilayo zibonakalisa enye indlela eco-friendly, kubalulekile ukuqwalasela iziphumo zazo ebezingalindelekanga zemveliso. Ukusetyenzwa kweekhemikhali kunye nezenzo zezolimo ezinxulumene nokuveliswa kwe-bioplastic kunokufaka isandla kungcoliseko kunye nemiba yokusetyenziswa komhlaba. Ukongeza, izibonelelo ezifanelekileyo zokulahla i-bio-plastiki zihlala zincinci, zigxininisa imfuneko yezicwangciso ezibanzi zolawulo lwenkunkuma.
Ngakolunye uhlangothi, iiplastiki ezinokuphinda zisetyenziswe zibonelela ngesisombululo esinyanzelisayo kunye nokusebenza okuqinisekisiweyo. Ngokukhuthaza ukurisayikilishwa kunye notyalo-mali kwiziseko ezingundoqo ukuze siyixhase, sinokuphambukisa inkunkuma yeplastiki kwindawo yokulahla inkunkuma kwaye sinciphise ifuthe lethu lokusingqongileyo. Ngelixa iiplastikhi ze-biodegradable zibonisa isithembiso, utshintsho olusingise kuqoqosho olujikelezayo, apho izixhobo ziphinda zisetyenziswe kwaye zisetyenziswe kwakhona, zinokubonelela ngesisombululo esizinzileyo sexesha elide kwingxaki yongcoliseko lweplastiki.
