Ukuthuthukiswa kanye nokusetshenziswa kwePlastiki ye-Biodegradable

Incazelo yamapulasitiki angaboli, iwukukhomba emvelweni, njengenhlabathi, isihlabathi, imvelo yamanzi, imvelo yamanzi, izimo ezithile ezifana nezimo zokwenziwa komquba kanye nezimo zokugaya ukudla okune-anaerobic, ukuwohloka okubangelwa isenzo se-microbial sokuba khona kwemvelo, futhi ekugcineni. ukubola ku-carbon dioxide (CO2) kanye/noma i-methane (CH4), amanzi (H2O) kanye nokwenza amaminerali ento equkethe usawoti we-inorganic, kanye ne-biomass entsha (efana nomzimba wezinto ezincane eziphilayo, njll.) yepulasitiki.

Ukuqhathaniswa kwamapulasitiki amaningana ajwayelekile angaboli

Ukukhiqiza nokusatshalaliswa kwamapulasitiki angaboli

Ngokwemininingwane yakamuva ekhishwe yi-European Bioplastics Association ngoSepthemba 2019, kusukela ngoSepthemba 2019, umthamo wonyaka wokukhiqiza wamapulasitiki angaboli emhlabeni wonke2144,000 amathani;

I-PLA (i-polylactic acid) yabaamathani angama-628,000, accounting for29.3%;

I-PBAT (i-polyadipic acid/butylene terephthalate) yabaamathani angama-606,800, accounting for28.3%;

Ipulasitiki ewohlokayo esekwe isitashi kwaba96.27 amathani, accounting for44.9%umthamo wepulasitiki obolayo emhlabeni wonke.

Ukusatshalaliswa komhlaba wonke kwamandla epulasitiki angaboli ngo-2019

Isimo se-Biodegradable

Ukuwohloka kwenhlabathi

I-PBAT, PHA, PCL ne-PBS ingehliswa ngokuphelele ngemva kwezinyanga ezi-5.

Izinga lokuwohloka kwezinto ze-PLA lihamba kancane, kuphela i-0.23% ngonyaka.

I-PLA ne-PKAT zingonakaliswa ngokuphelele esikhathini esingangesigamu sonyaka ngemva kokuhlanganiswa.

Ukuwohloka kwamanzi

I-PHA ne-PKAT zingonakaliswa ngokuphelele ezinsukwini ezingama-30~60 ngaphansi kwesimo samanzi olwandle esilingisiwe esingu-25℃±3℃.
