1. Diversification ntawm kev lag luam ntim yas
Rov qab los ntawm keeb kwm ntawm cov hnab yas, peb yuav pom tias cov hnab yas muaj keeb kwm ntau tshaj 100 xyoo.Tam sim no nyob rau hauv lub xyoo pua 21st, kev tshawb fawb thiab thev naus laus zis txuas ntxiv txhim kho, cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab txuas ntxiv tshwm sim, polyethylene, ntawv, aluminium ntawv ci, ntau yam yas, cov ntaub ntawv sib xyaw thiab lwm cov ntaub ntawv ntim tau dav siv, ntim aseptic, ntim khoom poob siab, tiv thaiv. Kev ntim khoom zoo li qub, kev ntim tshuaj tiv thaiv menyuam yaus, kev ntim khoom ua ke, ntim khoom sib xyaw, ntim khoom kho mob thiab lwm yam thev naus laus zis tau dhau los ua neeg paub tab, thiab cov ntaub ntawv ntim tshiab thiab cov khoom siv xws li cov hnab yas sawv ntsug tau tshwm sim, uas tau ua kom muaj zog ntawm kev ntim khoom hauv ntau txoj kev.
2. Cov teeb meem kev nyab xeeb ntawm cov ntaub ntawv yas
Yav dhau los, cov hnab ntim cov hnab yas muaj cov yas yas thiab bisphenol A (BPA), uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv, thiab cov xov xwm zoo li no tau tshwm sim ntau zaus.Yog li ntawd, tib neeg lub stereotype ntawm ntim yas yog "tshuaj lom thiab tsis zoo".Tsis tas li ntawd, qee cov tub lag luam uas tsis paub cai siv cov khoom siv tsis tau raws li qhov yuav tsum tau ua kom txo tau cov nqi, uas ua rau cov duab tsis zoo ntawm cov ntaub ntawv yas.Vim tias cov kev cuam tshuam tsis zoo no, tib neeg muaj qee qhov kev tiv thaiv rau cov ntim yas, tab sis qhov tseeb, cov yas siv rau ntim khoom noj muaj cov txheej txheem tag nrho ntawm EU thiab lub teb chaws txoj cai, thiab cov khoom siv raw siv los ntawm cov lag luam yuav tsum ua raws li cov cai ntawm cov kev cai no. , nrog rau muaj cov cai nruj EU thiab cov ncauj lus kom ntxaws txog REACH cov ntaub ntawv yas uas tuaj rau hauv kev sib cuag nrog zaub mov.
British Plastics Federation BPF tau taw qhia tias tam sim no lub ntim yas tsis yog tsuas yog muaj kev nyab xeeb xwb, tab sis kuj tseem ua rau muaj txiaj ntsig zoo rau pej xeem kev noj qab haus huv thiab kev vam meej ntawm tib neeg lub neej.
3. Degradable biopolymers dhau los ua ib qho kev xaiv tshiab rau cov khoom ntim
Qhov tshwm sim ntawm biodegradable cov ntaub ntawv ua rau ntim cov ntaub ntawv xaiv tshiab.Cov khoom noj khoom haus ruaj khov, kev nyab xeeb thiab zoo ntawm biopolymer cov khoom ntim tau raug kuaj thiab tshuaj xyuas, uas tau ua pov thawj tag nrho tias cov hnab ntim khoom biodegradable yog cov khoom ntim zoo tshaj plaws hauv ntiaj teb.
Tam sim no, biodegradable polymers tuaj yeem muab faib ua ob pawg: ntuj thiab hluavtaws.Ntuj degradable polymers muaj xws li hmoov txhuv nplej siab, cellulose, polysaccharides, chitin, chitosan thiab lawv cov derivatives, thiab lwm yam;Synthetic degradable polymers muab faib ua ob pawg: cov khoom siv dag zog thiab cov kab mob sib xyaw.Degradable polymers synthesized los ntawm cov kab mob xws li poly Hydroxyalkyl cawv esters (PHAs), poly (malate), hluavtaws degradable polymers xws li polyhydroxyesters, polycaprolactone (PCL), polycyanoacrylate (PACA), thiab lwm yam.
Niaj hnub no, nrog kev txhim kho tas mus li ntawm cov khoom siv lub neej, tib neeg tau them nyiaj ntau dua rau kev ntim khoom, thiab kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm kev ntim khoom tau dhau los ua lub hom phiaj meej.Yog li ntawd, yuav ua li cas thiaj li tsim cov khoom lag luam zoo ib puag ncig thiab tsis muaj kuab paug ntsuab ntim tau dhau los ua lub ntsiab lus tshiab uas cov tuam txhab ntim khoom hauv kuv lub tebchaws tau pib tsom mus rau.
