Kuvandudza uye Kushandiswa kweBiodegradable Plastics

Tsanangudzo yemapurasitiki anoodegradable, ndeyekunongedza kune zvakasikwa, senge ivhu, jecha, nharaunda yemvura, nharaunda yemvura, mamwe mamiriro akadai secompost uye anaerobic digestion mamiriro, kuparara kunokonzerwa nehutachiona hwekuita kwekuvapo kwezvisikwa, uye pakupedzisira. yakaora kuita carbon dioxide (CO2) uye/kana methane (CH4), mvura (H2O) uye mineralization yeine element inorganic salt, uye new biomass (senge muviri wemicroorganisms, etc.) wepurasitiki.

Kuenzanisa kweakawanda akajairika biodegradable mapurasitiki

Kubudirira uye kugovera mapurasitiki anoodegradable

Zvinoenderana nedata razvino rakaburitswa neEuropean Bioplastics Association munaGunyana 2019, kubva munaGunyana 2019, huwandu hwepasirese hwepagore hwekugadzira mapurasitiki anoodegradable ari.2144,000 matani;

PLA (polylactic acid) yaiva628,000 matani, accounting for29.3%;

PBAT (polyadipic acid/butylene terephthalate) yaiva606,800 matani, accounting for28.3%;

Starch-based degradable plastiki yaive96.27 matani, accounting for44.9%yepasi rose biodegradable plastic capacity.

Kugoverwa kwepasi rose kweiyo biodegradable mapurasitiki kugona muna 2019

Kwepasirese kudzika kudiwa kwemapurasitiki anogona kuparara muna 2019

Biodegradable mamiriro

Kuparara kwevhu

PBAT, PHA, PCL nePBS zvinogona kuderedzwa zvachose mushure memwedzi mishanu.

Mwero wekushatisa wezvinhu zvePLA unononoka, chete 0.23% pagore.

PLA nePKAT inogona kuderedzwa zvachose munenge hafu yegore mushure mekusanganiswa.

Kuparara kwemvura

PHA uye PKAT inogona kuderedzwa zvachose mumazuva makumi matatu ~ 60 pasi pemamiriro emvura yegungwa anofananidzwa e25℃±3℃.
