ʻO ka PBSA (polybutylene succinate adipate) kahi ʻano plastics biodegradable, i hana ʻia mai nā kumuwaiwai fossil, a hiki ke hoʻohaumia ʻia e nā microorganisms i ke kaiapuni kūlohelohe, me ka nui o ka decomposition ma mua o 90% i 180 mau lā ma lalo o ke kūlana o ka composting. ʻO ka PBSA kekahi o nā māhele hoihoi loa i ka noiʻi a me ka hoʻohana ʻana i nā plastics biodegradable i kēia manawa.
ʻElua mau māhele o nā palakiko biodegradable, ʻo ia hoʻi, nā palakiko bio-based degradable a me nā palakiko petroleum-based degradable. Ma waena o nā palakiko petroleum-based degradable, ʻo nā polyesters dibasic acid diol nā huahana nui, me PBS, PBAT, PBSA, etc., i hoʻomākaukau ʻia ma ka hoʻohana ʻana i ka butanedioic acid a me ka butanediol ma ke ʻano he mea maka, nona nā pono o ke kūpaʻa wela maikaʻi, nā mea maka maʻalahi e loaʻa, a me ka ʻenehana oʻo. Ke hoʻohālikelike ʻia me PBS a me PBAT, he haʻahaʻa ka heheʻe ʻana o ka PBSA, ke kahe kiʻekiʻe, ka crystallization wikiwiki, ka paʻakikī maikaʻi loa a me ka wikiwiki o ka degradation i ke kaiapuni kūlohelohe.
Hiki ke hoʻohana ʻia ʻo PBSA i ka hoʻopili ʻana, nā mea e pono ai i kēlā me kēia lā, nā kiʻiʻoniʻoni mahiʻai, nā mea lapaʻau, nā mea paʻi 3D a me nā ʻoihana ʻē aʻe.
