Kupanga ndi Kugwiritsa Ntchito Mapulasitiki Osasinthika

Tanthauzo la pulasitiki biodegradable, ndi kuloza ku chilengedwe, monga nthaka, mchenga, madzi chilengedwe, madzi chilengedwe, zinthu zina monga composting ndi anaerobic chimbudzi zinthu, kuwonongeka chifukwa cha tizilombo zochita za kukhalapo kwa chilengedwe, ndipo potsiriza. amawola kukhala mpweya woipa (CO2) ndi/kapena methane (CH4), madzi (H2O) ndi mineralization ya zinthu zomwe zili ndi mchere wosakhazikika, ndi biomass yatsopano (monga thupi la tizilombo toyambitsa matenda, ndi zina zotero) zapulasitiki.

Kuyerekeza mapulasitiki angapo omwe amatha kuwonongeka

Kupanga ndi kugawa kwa mapulasitiki owonongeka

Malinga ndi zomwe zatulutsidwa posachedwa ndi European Bioplastics Association mu Seputembara 2019, kuyambira Seputembara 2019, kuchuluka kwapachaka kwapachaka kwa mapulasitiki owonongeka2144,000 matani;

PLA (polylactic acid) anali628,000 matani, kuwerengera ndalama29.3%;

PBAT (polyadipic acid/butylene terephthalate) anali606,800 matani, kuwerengera ndalama28.3%;

Pulasitiki yowonongeka yochokera ku starch inali96.27 matani, kuwerengera ndalama44.9%mphamvu ya pulasitiki yapadziko lonse lapansi yowonongeka.

Kugawidwa kwapadziko lonse kwamphamvu zamapulasitiki owonongeka mu 2019

Kufunika kwapadziko lonse lapansi kwa mapulasitiki owonongeka mu 2019

Biodegradable chikhalidwe

Kuwonongeka kwa nthaka

PBAT, PHA, PCL ndi PBS zitha kuonongeka pakatha miyezi isanu.

Kuwonongeka kwa zida za PLA kumakhala pang'onopang'ono, kokha 0.23% pachaka.

PLA ndi PKAT zitha kuwonongeka kwathunthu pafupifupi theka la chaka mutaphatikizana.

Kuwonongeka kwa madzi

PHA ndi PKAT zitha kuonongeka kwathunthu m'masiku 30 ~ 60 pansi pamadzi am'nyanja a 25 ℃ ± 3 ℃.
