Nyanzvi mugadziri wemichina ye thermoforming.
Muna Kurume 2022, Fifth UN Environment Conference yakaramba ichipfuudza "Plastic Pollution Resolution (Draft)" kuNairobi, guta guru reKenya. Pamusangano uyu, mukuru wenyika, gurukota rezvemamiriro ekunze nevamwe vamiriri vanobva kunyika zana nemakumi manomwe neshanu vakasaina iyi nhoroondo. Sarudzo iyi ine chinangwa chekusimudzira hutongi hwepasi rose hwekudzikisa kusvibiswa kwepurasitiki uye inotarisira kupedza kusvibiswa kwepurasitiki panosvika 2024.
Kucherechedza kwezvinhu zvinoparara
Zvinoenderana neshumo yapfuura yezvakatipoteredza yakaburitswa neOECD (Sangano reEconomic Co-operation neBudiriro), muna 2019, kuburitswa kwepagore kwezvigadzirwa zvepurasitiki zvepasi rose zvingangoita matani mazana mana nemakumi matanhatu emamiriyoni, uye marara epurasitiki epagore asvika 353 miriyoni matani. Zvigadzirwa zvekugadzira, zvinosanganisira kurongedza epurasitiki (40%), zvinhu zvevatengi zvepurasitiki (12), machira (11%), nezvimwe.
Nekuvandudzwa kwemitemo, biodegradable zvinhu zvicharamba zvichiwedzera.
Makwikwi ekugona kugadzira
Parizvino, mapurasitiki anoparara pamusika anogona kukamurwa kuva marudzi maviri: "petroleum base" uye "biological base". Musiyano uripo pakati pezviviri unonyanya kukamurwa mukugadzira zvigadzirwa. Petroleum-based degradable plastic inogadzirwa zvichienderana nefossil simba, kunyanya inosanganisira PBS (polynoxylxylxylxyl glycol), PBAT (alcoholic glycolic glycolin uye phenyl -dysteenol (common polymer), PCL (polycopide), nezvimwewo . pachibage, mashanga nezvimwe zvipenyu, kunyanya zvinosanganisira PLA (polylactic acid) uye PHA (polyxide alkyl).
Pakati pezvinhu zvakataurwa pamusoro apa, zvichienzaniswa nezvimwe zvipenyu-zvinosvibisa zvinhu, PLA (polyal acid) uye PBAT mitengo yakaderera, uye nzira yekugadzira inenge yakakura. Iyo huru yakasarudzika yemapurasitiki echinyakare.
Zvigadzirwa zvePLA zvakanyanya chibage nemashanga. Mushure mekushandiswa, inogona kukurumidza kunyungudutswa kuita kabhoni dhaibhoni, mvura uye inorganic munyu pasi pecompost (industrial compost) mamiriro. (PLA) kugadzirwa kunoumba kabhoni kutenderera.
Tinofanira kusimudzira ruzivo rwekuchengetedzwa kwezvakatipoteredza uye kuderedza kusvibiswa kwepurasitiki. Yeduwholesale thermoforming muchina inogona kuburitsa PLA's imwe-nguva tableware, nyore uye nyore kushanda, akangwara chirongwa, izvo zvinogona kuzadzisa zvaunoda kugadzira.
