Tawv uas lwj tau thiab Tawv uas siv dua tshiab

A. Yog dab tsitawv tsiaj uas lwj tau:

Tawv uas lwj tau txhais tau tias tawv cuav thiab tawv hluavtaws raug pov tseg tom qab siv, thiab raug rhuav tshem thiab sib xyaw ua ke raws li kev ua haujlwm ntawm cov cell biochemistry thiab cov enzymes ntawm cov kab mob me me xws li cov kab mob, pwm (fungi) thiab algae los tsim dej, carbon dioxide, methane, thiab lwm yam. Nws dhau los ua PU lossis PVC tawv cuav tawv khoom siv nrog lub voj voog carbon hauv xwm.

B. Qhov tseem ceeb ntawm cov tawv tsiaj uas lwj tau

Daws qhov teeb meem loj tam sim no ntawm kev ua qias tuaj rau ib puag ncig. Tam sim no, txhua lub tebchaws tau tsim cov kev cai lij choj kom txwv tsis pub tsim thiab muag cov khoom siv polymer uas tsis lwj xws li cov yas ib txwm muaj.

C. Cov khoom lwj tauhom

Raws li qhov kawg ntawm kev puas tsuaj: kev puas tsuaj tag nrho thiab kev puas tsuaj ntawm cov khoom.

Cov yas uas lwj tag nrho yog ua los ntawm cov polymers ntuj los ntawm kev fermentation microbial lossis kev tsim cov polymers lwj tag, xws li thermoplastic starch plastics, aliphatic polyester (PHA), polylactic acid (PLA), starch/polyvinyl alcohol, thiab lwm yam.

Cov yas uas lwj thiab lwj feem ntau suav nrog cov hmoov txhuv nplej siab hloov kho (lossis puv) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, thiab lwm yam.

Raws li txoj kev puas tsuaj: cov ntaub ntawv photodegradable, biodegradation, photo/biodegradation, thiab lwm yam.

D. Kev kuaj thiab ntawv pov thawj thoob ntiaj teb:
Tebchaws Meskas: ASTM D6400; D5511

European Union: DIN EN13432

Nyiv Pooj: Nyiv Pooj GREENPLA daim ntawv pov thawj biodegradable

Australia: AS4736

E. Kev cia siab thiab kev loj hlob:

Tam sim no, vim tias "cov khib nyiab dawb" tau cuam tshuam loj heev rau qhov chaw nyob ntawm tib neeg, feem ntau lub tebchaws hauv ntiaj teb txwv tsis pub tsim, muag thiab siv cov khoom siv uas tsis lwj. Yog li ntawd, tawv nqaij cuav thiab tawv hluavtaws uas lwj tau yog qhov tseem ceeb ntawm tawv yav tom ntej, thiab nws kuj yog qhov yuav tsum tau ua tus qauv rau cov neeg siv khoom yuav.

A. Yog dab tsitawv siv dua tshiab:
Cov tawv rov ua dua tshiab yog hais txog cov khoom tawv cuav tiav lawm uas tsim los ntawm kev tsim cov tawv cuav thiab tawv hluavtaws, qee lossis tag nrho cov uas yog ua los ntawm cov khoom siv pov tseg, uas tau rov ua dua tshiab thiab rov ua dua tshiab rau hauv cov ntaub cob lossis tawv.

B. Hom khoom siv tawv rov ua dua tshiab:
Tam sim no, cov tawv cuav tseem ceeb yog tawv cuav thiab tawv hluavtaws uas tsim los ntawm kev siv cov ntaub rov ua dua tshiab.

Huaian Kaiyue Technology Development Co., Ltd. siv cov ntaub ntawv rov ua dua tshiab los tsim cov tawv hluavtaws, thiab qhov zoo dua rau ib puag ncig yog cov tawv hluavtaws rov ua dua tshiab uas siv dej. Ua tiav qhov tsis muaj VOC emissions, tsis muaj kuab paug hauv cov txheej txheem tsim khoom, thiab kev tiv thaiv ib puag ncig ntsuab.

C. Lub ntsiab lus ntawm cov tawv nqaij rov ua dua tshiab:
Yuav kom tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab kev txo qis pa phem, kev siv dua thiab rov siv dua cov peev txheej, thiab txhawb kev lag luam thiab kev txhim kho kev sib raug zoo. Ntau thiab ntau lub tuam txhab thoob ntiaj teb nto moo ua si daim npav ntawm "kev tiv thaiv ib puag ncig" thiab tawm tswv yim siv cov khoom siv zoo rau ib puag ncig, yog li cov khoom siv rov ua dua thiab cov khoom siv rov ua dua tau dhau los ua lawv "cov neeg hlub".

D. Kev kuaj thiab daim ntawv pov thawj:
GRS (Tus Txheej Txheem Rov Siv Dua Thoob Ntiaj Teb) - Daim Ntawv Pov Thawj Txheej Txheem Rov Siv Dua Thoob Ntiaj Teb, Boze tawv muaj nws

E. Cov txiaj ntsig ntawm daim ntawv pov thawj GRS:
1. Kev lees paub thoob ntiaj teb, kom tau daim ntawv tso cai rau cov khoom nkag mus rau theem thoob ntiaj teb;

2. Cov khoom muaj cov pa roj carbon tsawg thiab zoo rau ib puag ncig, thiab tuaj yeem taug qab tau;

3. Nkag mus rau hauv lub kaw lus teev cov npe yuav khoom ntawm cov tuam txhab nto moo thoob ntiaj teb thiab cov npe thoob ntiaj teb;

4. Ua raws li cov kev cai ntawm kev ua lag luam ntawm "ntsuab" thiab "kev tiv thaiv ib puag ncig", thiab txhim kho cov teeb meem kev siv tshuab ntawm cov khoom

5. Txhim kho kev paub txog hom lag luam ntawm lub tuam txhab.
