PBSA (polybutylene succinate adipate) ndi mtundu wa mapulasitiki owonongeka, omwe nthawi zambiri amapangidwa kuchokera ku zinthu zakale, ndipo amatha kunyozedwa ndi tizilombo tating'onoting'ono m'chilengedwe, ndi kuwonongeka kwa mlingo woposa 90% m'masiku 180 pansi pa chikhalidwe cha composting. PBSA ndi imodzi mwamagulu omwe ali ndi chidwi kwambiri pa kafukufuku ndi kugwiritsa ntchito mapulasitiki omwe amatha kuwonongeka pakali pano.
Mapulasitiki omwe amatha kuwonongeka ali ndi magulu awiri, omwe ndi mapulasitiki owonongeka a bio-based and bio-based pulasitiki owonongeka.Pakati pa mapulasitiki owonongeka a petroleum, dibasic acid diol polyesters ndizinthu zazikulu, kuphatikizapo PBS, PBAT, PBSA, ndi zina zotero, zomwe zimakonzedwa pogwiritsa ntchito butanedioic acid ndi butanediol monga zipangizo, zomwe zimakhala ndi ubwino wotsutsa kutentha, zosavuta. -Kupeza zinthu zopangira, ndiukadaulo wokhwima.Poyerekeza ndi PBS ndi PBAT, PBSA ili ndi malo osungunuka otsika, kusungunuka kwamadzimadzi, crystallization mofulumira, kulimba kwambiri komanso kuwonongeka kwachangu m'chilengedwe.
