Umenzi ochwephesha woomatshini be-thermoforming.
Ngo-Matshi i-2022, iNkomfa yeSihlanu ye-UN yaqhubeka idlulisela "iSigqibo sePlastiki yoNgcoliseko (i-Draft)" eNairobi, ikomkhulu laseKenya. Kule ntlanganiso, intloko yelizwe, umphathiswa wendalo kunye nabanye abameli abavela kumazwe angama-175 basayine le mbali. Isisombululo sijolise ekukhuthazeni ulawulo lwehlabathi lokunciphisa ungcoliseko lweplastiki kwaye sinethemba lokuphelisa ungcoliseko lweplastiki ngo-2024.
Ukuqwalaselwa kwezinto ezigqwesileyo
Ngokwengxelo yangaphambili yokusingqongileyo ekhutshwe yi-OECD (uMbutho weNtsebenziswano yoQoqosho kunye noPhuhliso), ngo-2019, imveliso yonyaka yemveliso yeplastiki yehlabathi imalunga ne-460 yezigidi zeetoni, kwaye inkunkuma yeplastiki yonyaka ifikelele kwi-353 yezigidi zeetoni. Iimveliso zemveliso, kubandakanywa ukupakishwa kweplastiki (40 %), iimpahla zabathengi beplastiki (12), iingubo (11%), njl.
Ngokuqulunqwa kwemigaqo-nkqubo, izinto eziguquguqukayo ze-biodegradable ziya kuqhubeka zikhula.
Ukhuphiswano lwamandla okuvelisa
Okwangoku, iplastiki eyonakalisayo kwimarike inokwahlulwa ibe ziindidi ezimbini: "isiseko sepetroleum" kunye "nesiseko sebhayoloji". Umahluko phakathi kwezi zimbini zahlulwe ikakhulu kwimveliso yemathiriyeli ekrwada. Ipetroleum-based degradable plastic iveliswa ngokusekelwe kumandla efosili, ingakumbi iPBS (polynoxylxylxylxyl glycol), PBAT (alcoholic glycolic glycolin kunye nephenyl -dysteenol (common polymer), PCL (polycopide), njl. kwingqolowa, iindiza kunye nezinye izinto zebhayoloji, ngokukodwa i-PLA (i-polylactic acid) kunye ne-PHA (i-polyxide alkyl).
Phakathi kwezinto ezichazwe ngasentla zezinto eziphilayo, xa kuthelekiswa nezinye izinto eziphilayo, i-PLA (i-polyal acid) kunye nexabiso le-PBAT liphantsi, kwaye inkqubo yokuvelisa ikhulile. Eyona ndlela iphambili yeeplastiki zemveli.
Iimathiriyeli ekrwada zePLA ubukhulu becala ngumbona kunye neendiza. Emva kokusetyenziswa, inokubola ngokukhawuleza ibe yikharbon diokside, amanzi kunye neetyuwa ze-inorganic phantsi kweemeko zomgquba (umgquba wamashishini). (PLA) imveliso yenza umjikelo wekhabhoni.
Kufuneka sikhulise ulwazi ngokhuseleko lwendalo esingqongileyo kwaye sinciphise ungcoliseko lweplastiki. Yethuumatshini wokuthengisa we-thermoforming inokuvelisa i-PLA ye-tableware yexesha elinye, ukusebenza okulula kunye nokufanelekileyo, inkqubo ehlakaniphile, enokufikelela kwiimfuno zakho zemveliso.
