Txoj Kev Loj Hlob Ntawm Biodegradable Plastics

Nyob rau hauv 1997, lub ntiaj teb no degradable yas kev lag luam tau kwv yees tias nyob ib ncig ntawm 20 lab phaus, nrog ib tug muag khoom ntawm 23 lab US dollars; Nws xav tias yuav nce 35% los ntawm 2004. Cov yas degradable tam sim no nyob rau hauv Teb Chaws Asmeskas thiab Nyiv kev lag luam muaj xws li biodegradable polyester, xws li polylactic acid, biodegradable PET, polybutylene succinate / hexanoate, polyhydroxybutyrate / valerate, polyethylene succinate, polyesteramide, thiab polycaprolactone / sib tov; Starch thiab nws cov sib tov; Thiab lwm yam plastics ntxiv nrog cov additives los txhim kho lub peev xwm degradation. Yog vim li cas rau txoj kev loj hlob yog kev nce hauv kev siv cov khoom siv hauv ib puag ncig, thiab lwm qhov laj thawj yog txo cov nqi tsim khoom. Los ntawm kev nthuav dav ntau lawm thiab kev lag luam, cov tuam ntxhab tau txo lawv cov nqi. Txawm li cas los xij, tus nqi siab ntawm biodegradable resins thiab muaj zog dominance ntawm ntau yam plastics uas twb muaj lawm hauv lawv lub khw ua rau nws nyuaj rau biodegradable plastics nkag mus rau hauv kev ua lag luam.
