Ngomhla we-9 kuTshazimpuzi ka-2024, izazinzulu zaseTshayina zapapasha inqaku kwijenali yeNdalo yeKhemistry malunga nokuphinda kusetyenziswe izinto ezirhabaxa ukuvelisa ipetroli ekumgangatho ophezulu, ukuphumeza ukusetyenziswa ngokufanelekileyo kwenkunkuma yeplastiki ye-polyethylene.
Inkunkuma yeplastiki ibisoloko ingomnye wemingeni enzima ejongene nemekobume yehlabathi, kwaye isixa esikhulu se-scaffolds sibangele umonakalo omkhulu kwi-ecology. Kwiiplastiki zenkunkuma, ezinokuthi ziguqulelwe kwiingxowa zeplastiki, i-non-letter "carbon-carbon bonds" kunzima ukuyivula kunye nokutshabalalisa phantsi kweemeko zokushisa eziphantsi. Le nto intsha ifunyenwe zizazinzulu zaseTshayina izise ithemba ekusonjululweni kwale ngxaki.
Ngokolwazi, obu buchwephesha bunokuguqula ngokufanelekileyo inkunkuma yeplastiki ibe yipetroli ekumgangatho ophezulu ngothotho lwemichiza entsonkothileyo kunye negqwesileyo. Oku akuboneleli kuphela ngeengcamango ezintsha zokunyanga inkunkuma yeplastiki, kodwa kusombulula ingxaki yokunqongophala kwamandla kwiprogram.
Iingcali zithi esi siphumo kulindeleke ukuba sisetyenziswe kwinqanaba elikhulu kwixesha elizayo kwaye sikhuthaze uphuhliso loshishino lokubuyisela iplastiki. Ukuba inokukhuthazwa kwinqanaba elikhulu, ayiyi kunciphisa kuphela ungcoliseko lwendalo olubangelwa yinkunkuma yeplastiki, kodwa idale ixabiso elikhulu lezoqoqosho. Ndiyakholelwa ukuba ngeenzame eziqhubekayo zenzululwazi, siya kujonga phambili kwikamva elicocekileyo neliluhlaza.
