Yog ibbiodegradable pov tseg taistxiav tximcompostablethiab vice versa?Dab tsi yog qhov txawv ntawmbiodegradable thiabcompostable tais diav - phaj, iav, cutlery?
Lo lus nug tshwm sim dua thiab cov lus teb feem ntau tsis meej pem.Peb tau muab tso ua ke ntawm cov lus hais thiab sau, muab rau koj ib tug ncaj ncees thiab yooj yim version uas yuav pab tau koj nrhiav tau koj txoj kev.
Cov kev tsim nyog, biodegradable thiab compostable, yog txhais nyob rau hauv ib tug European tus qauv - NF 13432 - uas qhia qhov txawv ntawm compostable thiab biodegradable.Peb muab cov ntsiab cai:
Biodegradable yog hloov dua siab tshiab ntawm cov khoom rau hauv carbon dioxide, dej thiab humus.Cov khoom siv yog suav tias yog biodegradable yog tias nws ncav cuag 90% ntawm biodegradation tom qab 6 lub hlis.Cov khoom lag luam biodegradable decomposes thiab dhau los ua bio-assimilable nyob rau hauv qhov kev txiav txim ntawm micro-organisms, oxygen, kub, av noo thiab cua sov.Tsis muaj kev lav phib xaub rau qhov loj ntawm cov khoom tau txais.
Tag nrho cov khoom siv compostable yuav tsum biodegradable tab sis tsis yog lwm txoj hauv kev.
Qhov tseeb, ua kom compostable cov khoom siv yuav tsum hwm cov txheej txheem ntxiv.Qee cov khoom lag luam biodegradable, thaum tsim nyog rau qhov tsim nyog, yog ua los ntawm cov khoom siv uas, feem ntau ntawm cov khoom siv ntxiv nyob rau hauv lawv cov muaj pes tsawg leeg, yuav tawg, degrade, nyob rau hauv qhov xwm txheej.Tab sis tsis ploj tag nrho yam tsis muaj teeb meem los yog teeb meem.
Ib qho khoom siv compostable tsis muaj ib qho ntawm cov khoom no.Yuav kom suav hais tias compostable, cov khoom yuav tsum decompose ntawm tib tus nqi li cov nroj tsuag.Cov khoom - phaj, iav, cutlery ... - ua los ntawm fiber ntau, pulp, ntoo, PLA, ... yog compostable.
Qhov no kuj txhais tau hais tias cov khoom siv compostable tuaj yeem hloov mus rau hauv cov khoom siv compost zoo hauv kev lag luam composting installation.Kev ua liaj ua teb ua liaj ua teb yuav tsum hwm cov qauv zoo (kub 75 ° -80 °, av noo 65-70% thiab cov pa oxygen 18-20%).Nyob rau hauv cov xwm txheej no, cov txheej txheem composting yuav siv li 12 lub lis piam.Hauv "tsev-ua" compost, qhov kub tsis tshua muaj siab tshaj 40 ° thiab cov av noo sib txawv raws li cov xwm txheej sab nraud.
Yog li, composting yog optimization ntawm biodegradation txheej txheem.Nws muaj nyob rau hauv provoking thiab tswj, nyob rau hauv qhov zoo tshaj plaws ua tau tej yam kev mob, dab tsi twb ua.
Nov yog qhov sib txawv piav qhia ntawm biodegradable thiab compostable thiab vim li cas cov khoom siv compostable yog biodegradable tab sis tsis yog qhov txawv.
Ntawm Zhongxin peb tau mob siab rau cov qauv no uas yuav dhau los ua cov qauv tshiab thiab txhawb nqa kev coj tus cwj pwm hauv zej zog ntau dua.Peb yog li nthuav tawm cov khoom hauv cov khoom lag luam - phaj, iav, cutlery, tablecloths, napkins - uas tam sim no compostable zoo thiab yog li biodegradable.
Zhongxin muaj ntau yam khoom muaj tswv yim tsim los ntawm cov khoom siv dua tshiab thiab siv dua tshiab, xws li tais, khob, hau, phaj thiab ntim.
