1. Txheej txheem cej luam ntawm kev lag luam saw:
Lub npe tag nrho ntawm polylactic acid yog poly lactic acid lossis poly lactic acid. Nws yog cov khoom siv polyester siab molecular tau los ntawm polymerization nrog lactic acid lossis lactic acid dimer lactide li monomer. Nws belongs rau cov khoom siv hluavtaws siab molecular thiab muaj cov yam ntxwv ntawm lub hauv paus lom thiab degradability. Tam sim no, polylactic acid yog cov yas biodegradable nrog kev lag luam loj tshaj plaws, cov khoom siv loj tshaj plaws thiab siv dav hauv ntiaj teb. Cov dej ntws ntawm polylactic acid kev lag luam yog txhua yam ntawm cov khoom siv yooj yim, xws li pob kws, qab zib, qab zib beet, thiab lwm yam, qhov nruab nrab ncav cuag yog kev npaj ntawm polylactic acid, thiab cov dej ntws qis yog siv cov polylactic acid, nrog rau kev tiv thaiv ib puag ncig. tableware, ib puag ncig tiv thaiv ntim, thiab lwm yam.
2. Upstream kev lag luam
Tam sim no, cov khoom siv raw ntawm kev lag luam polylactic acid hauv tsev yog lactic acid, thiab lactic acid feem ntau yog npaj los ntawm pob kws, qab zib, qab zib beet thiab lwm yam khoom ua liaj ua teb. Yog li ntawd, cov qoob loo cog kev lag luam dominated los ntawm pob kws yog cov upstream kev lag luam ntawm polylactic acid industrial saw. Los ntawm qhov kev xav ntawm Tuam Tshoj cov pob kws tawm thiab cog thaj chaw, Tuam Tshoj cov pob kws cog qoob loo yuav ncav cuag 272.55 lab tons hauv xyoo 2021, nrog rau qhov loj, thiab thaj chaw cog tau ruaj khov ntawm 40-45 lab hectares rau ntau xyoo. Los ntawm lub sijhawm ntev ntawm cov pob kws hauv Suav teb, nws tuaj yeem cia siab tias cov khoom ntawm pob kws yuav nyob ruaj khov rau yav tom ntej.
Raws li rau lwm cov khoom siv raw uas tuaj yeem siv los tsim cov lactic acid, xws li qab zib thiab qab zib beet, Tuam Tshoj cov khoom lag luam tag nrho hauv xyoo 2021 yog 15.662 lab tons, uas yog qis dua li xyoo dhau los, tab sis tseem nyob rau theem ib txwm muaj. Thiab cov tuam txhab thoob plaws ntiaj teb tseem tab tom tshawb nrhiav txoj hauv kev tshiab los npaj lactic acid, xws li siv cov suab thaj hauv cov ntoo fibers xws li straw thiab sawdust los npaj lactic acid los yog tshawb nrhiav cov txheej txheem ntawm kev siv methane los tsim cov lactic acid. Ntawm qhov tod tes, cov khoom siv ntawm kev lag luam sab saud ntawm polylactic acid yuav ruaj khov rau yav tom ntej.
3. Kev lag luam nruab nrab
Raws li cov khoom siv biodegradable tag nrho, polylactic acid tuaj yeem nqa cov khoom siv raw mus rau hauv cov peev txheej rov tsim dua thiab rov ua dua tshiab, uas muaj qhov zoo uas cov khoom siv roj av tsis muaj. Yog li ntawd, kev noj ntawm polylactic acid nyob rau hauv lub lag luam domestic yog nce. Kev siv hauv tsev hauv 2021 yog 48071.9 tons, nce 40% xyoo-rau-xyoo.
Vim tias muaj peev xwm tsim tau tsawg ntawm polylactic acid nyob rau hauv Suav teb, cov khoom lag luam ntawm polylactic acid nyob rau hauv Suav teb yog ntau dua li cov khoom xa tawm. Nyob rau hauv xyoo tas los no, cov khoom lag luam ntawm polylactic acid tau nce sai sai los ntawm kev thov hauv tsev. Nyob rau hauv 2021, kev ntshuam ntawm polylactic acid mus txog 25294.9 tons. Kev xa tawm ntawm polylactic acid kuj ua tau zoo nyob rau hauv 2021, mus txog 6205.5 tons, ib xyoo-rau-xyoo nce ntawm 117%.
Daim ntawv tshaj tawm cuam tshuam: tshaj tawm txog kev txhim kho kev soj ntsuam thiab kev txhim kho kev cia siab ntawm Tuam Tshoj cov khoom lag luam polylactic acid los ntawm 2022 txog 2028 tawm los ntawm Zhiyan kev sab laj
4. Kev lag luam hauv qab
Hauv cov ntawv sau qis, polylactic acid tau siv rau hauv ntau qhov chaw nrog nws qhov tshwj xeeb biocompatibility thiab biodegradability. Tam sim no, nws tau siv dav hauv kev ntim khoom noj khoom haus qib ntim, tableware, zaj duab xis ntim hnab thiab lwm yam khoom thiab teb. Piv txwv li, cov yeeb yaj kiab yas ua liaj ua teb ua los ntawm polylactic acid tuaj yeem ua tiav thiab ploj mus tom qab sau qoob loo, uas yuav tsis txo cov dej thiab fertility ntawm cov av, tab sis kuj zam cov nqi zog ntxiv thiab cov nqi khiav lag luam uas yuav tsum tau ua rau kev rov qab los. yas zaj duab xis, uas yog qhov dav dav ntawm txoj kev loj hlob ntawm yas zaj duab xis nyob rau hauv Tuam Tshoj yav tom ntej. Lub cheeb tsam npog los ntawm yas zaj duab xis nyob rau hauv Tuam Tshoj yog hais txog 18000 hectares, thiab kev siv cov yas zaj duab xis nyob rau hauv 2020 yog 1357000 tons. Thaum degradable yas zaj duab xis tuaj yeem nrov, kev lag luam polylactic acid muaj qhov chaw loj rau kev loj hlob yav tom ntej.
