Wahi a nā kumu waiwai o nā plastic biodegradable, aia ʻelua ʻano o Biodegradable Plastics: Bio based a me petrochemical based. ʻO ka PBAT kahi ʻano o nā plastic biodegradable e pili ana i ka petrochemical.
Mai nā hopena o ka hoʻokolohua biodegradation, hiki ke hoʻohaʻahaʻa loa ʻia ka PBAT ma lalo o nā kūlana kūlohelohe maʻamau a kanu ʻia i ka lepo no 5 mau mahina.
Inā aia ka PBAT i loko o ke kai, aia nā microorganism i hoʻololi ʻia i ka paʻakai kiʻekiʻe i loko o ka wai kai. Ke 25 ℃ ± 3 ℃ ka mahana, hiki ke hoʻohaʻahaʻa loa ʻia ma kahi o 30-60 mau lā.
Hiki ke hoʻoheheʻe ʻia nā plastic biodegradable PBAT ma lalo o nā kūlana compost, nā kūlana ʻē aʻe e like me ka mea hoʻoheheʻe anaerobic, a me ke ʻano kūlohelohe e like me ka lepo a me ka wai kai.
Eia nō naʻe, pili ke kūlana hoʻohaʻahaʻa kikoʻī a me ka manawa hoʻohaʻahaʻa o ka PBAT i kāna ʻano kemika kikoʻī, ka ʻano huahana a me nā kūlana kaiapuni degradation.
