PBAT ipurasitiki inogona kuparara. Inoreva rudzi rwemapurasitiki akaderedzwa nehutachiona huripo mune zvakasikwa, senge mabhakitiriya, molds (fungi) uye algae. Yakanaka biodegradable plastiki imhando yemhando yepolymer zvinhu zvine mashandiro akanaka, ayo anogona kuodzwa zvachose nemasikirini ezvakatipoteredza mushure mekuraswa, uye pakupedzisira kuve inorganic uye kuva chikamu chakakosha chekabhoni kutenderera mune zvakasikwa.
Misika mikuru inonangwa yemapurasitiki anogona kuparara ipurasitiki yekurongedza firimu, firimu rekurima, mabhegi epurasitiki anoraswa uye tafura yepurasitiki inoraswa. Kuenzaniswa neyechinyakare epurasitiki yekurongedza zvinhu, mutengo wezvinhu zvitsva zvinoparara wakakwira zvishoma. Nekudaro, nekusimudzira kwekuziva kwezvakatipoteredza, vanhu vari kuda kushandisa zvinhu zvitsva zvinoodza biodegradable nemitengo yakakwira zvishoma yekuchengetedzwa kwezvakatipoteredza. Kukwidziridzwa kweruzivo rwezvakatipoteredza kwaunza mikana mikuru yebudiriro kuindasitiri inodegradable yezvinhu zvitsva.
Nekusimukira kwehupfumi hweChina, kutambirwa kwakabudirira kweMitambo yeOlympic, World Expo nezvimwe zviitiko zvakakura zvakavhundutsa pasirese, kudiwa kwekuchengetedzwa kwenhaka yetsika yepasi uye nzvimbo dzinoyevedza dzenyika, dambudziko rekusvibiswa kwezvakatipoteredza rakakonzera. nemapurasitiki akabhadharwa zvakanyanya uye zvakanyanya kutariswa.
