Vim nws lub teeb yuag, lub zog siab, yooj yim thiab tus nqi qis, cov hnab yas tuj tau tsim sai thiab siv dav hauv kev ntim cov ntaub ntawv txij li xyoo 1970, pab txhawb tib neeg' lub neej. Txawm li cas los xij, vim tias feem ntau cov khoom ntim yas yog qhov nyuaj rau degrade ib txwm, lawv cov khib nyiab ntim yuav tsim cov khib nyiab mus tas li, uas yuav ua rau ib puag ncig. Yog li ntawd, thaum siv thiab tsim cov khoom ntim yas, tag nrho cov kev txiav txim siab yuav tsum tau muab rau cov degradability, recycling possibilities, thiab recycling txoj kev ntawm cov khoom ntim yas. Tsoom fwv tseem yuav tsum tau ntsuas los txhawb kev tshawb fawb thiab kev tsim cov yas degradable los txhawb txoj kev loj hlob ntawm kev lag luam ncig.
Raws li tus tshiab Z txheeb cais muab los ntawm National Bureau of Statistics thiab lub Federation of Light Industry, nyob rau hauv 2005 lub ntsiab economic ntsuas ntawm Tuam Tshoj' s plastics kev lag luam ua tiav tag nrho cov kev loj hlob, nce ntau tshaj 25%, thiab qhov ua tiav cov khoom tsim tawm tau mus txog 501.1 billion yuan. Raws li cov kws tshuaj ntsuam xyuas kev lag luam, txawm hais tias tus nqi ntawm cov khoom siv yas tseem nyob rau xyoo 2005, kev lag luam muaj zog xav tau, nrog rau kev nce hauv kev xa tawm, kev loj hlob ntawm cov ntawv thov tshiab thiab kev nce hauv cov txiaj ntsig ntawm cov khoom muaj nqis ntxiv, tseem txhawb nqa. tag nrho kev loj hlob ntawm kev lag luam' cov kev ntsuas kev lag luam. Tam sim no, ntim tau dhau los ua cov neeg siv khoom loj ntawm cov yas, nrog kev noj txhua xyoo ntau dua 6 lab tons.
Txawm li cas los xij, cov hnab yas zoo nkauj zoo li tig mus rau hauv cov khib nyiab uas tsis siv hauv ib lub sijhawm. Nrog rau kev loj hlob ntawm cov ntim yas, cov teeb meem ib puag ncig tau dhau los ua qhov hnyav zuj zus. Tshwj xeeb, cov khoom ntim yas pov tseg pov tseg yog loj, tawg, tawg, thiab nyuaj rau sau. Qee cov khib nyiab no tau muab pov tseg thiab tawg mus rau hauv av, ua paug rau lub nroog' qhov zoo li thiab ib puag ncig toj roob hauv pes, thiab muaj kev cuam tshuam tsis zoo rau kev lag luam thiab ib puag ncig ecological.
Txhawm rau daws qhov teeb meem no, tsoomfwv, cov tuam txhab thiab cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis feem ntau tau ua haujlwm ntau. Qee tus neeg tawm tswv yim siv tsawg dua, txwv, lossis txwv lawv; qee tus neeg tawm tswv yim thiab tsim cov kev cai hauv zos los tswj kev degradation ntawm plastics; ib txhia hais kom siv nyiaj txiag txhais tau tias (cov se, nqi) coj noj coj ua. Tu siab, ntau yam kev ntsuas tau muaj kev cuam tshuam me ntsis. Cov kev txwv thiab kev txwv tsis pub ua rau cov neeg zoo tib yam xav tias tsis yooj yim, thiab cov nqi them tau nce lub nra rau cov tib neeg.
Qhov tseeb tau ua pov thawj tias lub neej niaj hnub no yog sib cais los ntawm cov yas. Nws yog qhov zoo dua los cuam tshuam thiab tshem tawm, siv cov khoom siv nrog kev ua haujlwm zoo dua thiab tus nqi sib piv, thiab siv cov thev naus laus zis thiab cov txheej txheem ntau dua nrog cov yam ntxwv ntawm lub sijhawm los tsim cov yas degradable, thiab ua rau kom rov ua dua thiab rov siv cov khoom pov tseg yas. Nws yog txoj hauv kev los daws qhov teeb meem ntawm cov pa phem dawb. Tus kws sau ntawv ntseeg tias tam sim no kev rov ua dua tshiab thiab ua tiav cov khoom ntim yas ntim khoom pov tseg yuav tsum tau siv ntau txoj hauv kev thiab ntau txoj hauv kev, thiab txheeb lawv raws li lub ntsiab lus ntawm kev tsim kho kom ruaj khov ntawm ib puag ncig ecological. Thawj yog recycling, thiab qhov thib ob yog recycling los yog incineration kom tau lub zog. , Qhov thib peb yog pov tseg, thiab plaub yog hloov nrog cov khoom siv biodegradable.
Recycling yog tsim nyog rau cov ntim khoom siv rau kev thauj mus los thiab ntim khoom, xws li pallets, turnover boxes, loj ntim thawv, thiab cov thoob yas. Rau cov khoom ntim yas rov qab tau yooj yim, kev hloov kho lub cev thiab tshuaj lom neeg tuaj yeem siv los rov tsim dua tshiab, kom cov khoom siv tsawg tuaj yeem siv dua. Rau cov ntim ntim yas pov tseg uas nyuaj rau kev rov ua dua tshiab, kev ua kom tsis huv, pov tseg, lossis hloov cov khoom siv biodegradable yuav yog qhov kev xaiv zoo. Txawm hais tias nws nyuaj rau taw qhia tias txoj kev twg Z yog qhov zoo dua, peb yuav tsum hais txog txoj kev twg yog qhov tsim nyog dua. Raws li qhov xwm txheej tiag tiag hauv txhua cheeb tsam thiab thaj chaw, qhov kev xaiv zoo tshaj plaws yog xaiv qhov yog.
