Thaum nws los txog rau cov hnab yas, tib neeg yuav xav tias lawv yuav ua rau "muaj kuab paug dawb" rau peb ib puag ncig.
Yuav kom txo tau qhov kev nyuaj siab ntawm cov hnab yas rau ib puag ncig, Tuam Tshoj kuj tau tshaj tawm tshwj xeeb "kev txwv yas", tab sis qhov cuam tshuam yog txwv, thiab qee tus kws tshaj lij hais ncaj qha tias "kev txwv yas" tsuas yog ncua qhov kev puas tsuaj ntawm yas thiab tsis daws qhov teeb meem no.
Txawm li cas los xij, txhua tus neeg lub neej yeej tsis sib cais los ntawm cov hnab yas. Tam sim no ibhom tshiabntawm lub hnab yas tau tawm los.

Ib lub hnab yas dawb zoo li qub. Muab tso rau hauv dej kub li ntawm 80 ℃. Ob peb feeb tom qab. Lub hnab yas ploj mus.
Muaj kev tshaj tawm tias lub hnab yas zoo li qub no tuaj yeem yaj tau hauv ob peb feeb raws li qhov xav tau, thiab 100% lwj mus rau hauv carbon dioxide thiab dej hauv ib nrab xyoo, uas yog tus phooj ywg zoo rau ib puag ncig.
Cov khoom siv raw ntawm hom hnab yas no yog polyvinyl cawv, uas yog los ntawm cov hmoov txhuv nplej siab xws li cassava, qos liab qab zib, qos yaj ywm, pob kws thiab lwm yam. Nws yog ib qho tsis muaj xim, tsis muaj tshuaj lom, tsis xeb, biodegradable tag nrho cov organic polymer yaj hauv dej. Cov khoom siv tuaj yeem lwj tag nrho mus rau hauv carbon dioxide thiab dej yam tsis tau kho.
Yog li ntawd, peb tuaj yeem pom tias txhua yam hnab yas ua los ntawm cov khoom siv no yaj tau hauv dej. Cov khoom tau txais daim ntawv pov thawj patent tsim tawm los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Txawj Ntse ntawm Lub Xeev, thiab cov chaw haujlwm cuam tshuam kuj tau dhau qhov kev tshuaj xyuas ntawm cov khoom.

Tom qab yaj rau hauv dej, cov khoom no yuav raug rhuav tshem tag nrho thiab ua carbon dioxide thiab dej, uas yuav tsis ua rau muaj kuab paug thiab ua rau puas tsuaj rau qhov zoo ntawm cov dej. Ntxiv mus, yog tias cov dej yaj rau hauv av hauv xwm, nws yuav tsis tsuas yog tsis ua rau muaj kuab paug thiab ua rau puas tsuaj rau qhov zoo ntawm cov av, tab sis kuj muaj cov txiaj ntsig zoo rau kev txhim kho av. Nws yog cov khoom siv zoo rau ib puag ncig.
Vim nws muaj peev xwm lwj tag nrho, cov khoom lag luam no hu ua "plastic edible".

Nws to taub tias qhovkev tsim khoomCov txheej txheem ntawm qhov project kuj yog ntsuab thiab tus phooj ywg ib puag ncig, tsis muaj ntxiv cov khoom ntxiv, tsim peb cov khib nyiab thiab tsis ua rau ib puag ncig puas tsuaj. Biogas, ib qho khoom siv los ntawm kev tsim cov khoom siv raw, tuaj yeem siv rau kev tsim hluav taws xob thiab cua sov, thiab cov khib nyiab seem tuaj yeem ua rau cov chiv organic rov qab mus rau lub teb kom paub txogkev siv cov peev txheej dua tshiab. nws tuaj yeem hais tias nws yog ib qho project tiv thaiv ib puag ncig ntsuab kiag li.
