Polyhydroxyalkanoate PHA
Ko te Polyhydroxyalkanoate, e whakarāpopototia ana ko te PHA, he kupu whānui mō tētahi momo polyester taumaha-ngota teitei i hangaia e ngā moroiti. Ka hangaia te PHA mai i te kānga, te rīwai me ētahi atu matū koiora i ahu mai i te māngaro, i te kakau witi rānei hei rauemi mata, ka whakapūkarahia hei whakaputa waikawa lactic, ā, ka purea anō, ka whakapūkarahia hei hanga PLA parakore teitei, he pai mō te taiao, kāore he paitini, he ārai mate huakita, he ārai mura, ā, he pai te hototahi ki te koiora.
Ko te momo whakakoi werohanga PHA, te momo mirumiru, te momo kiriata pupuhi, te momo pahuka, me ētahi atu rauemi pirau-katoa puta noa i te raina katoa. Ko ngā PHA he momo rauemi polyhydroxyalkanoates (PHA), he rauemi biopolymer i hangaia tika mā te whakapūtanga moroiti i roto i ngā moroiti. He nui ngā āhuatanga tāpiri uara o ngā PHA pēnei i te hototahitanga koiora, te pirau-koiora, me ngā āhuatanga piezoelectric. He pai te whakamahinga me ngā āhuatanga tukatuka, ā, he rite ō rātou āhuatanga taketake ki te polypropylene. Ka taea te tukatuka me te whakakoi mā te whakamahi i ngā taputapu tukatuka kirihou tuku iho pēnei i te whakakoi werohanga, te extrusion, te pupuhi kiriata, te kukume waea, me te whakakoi, ā, ka taea te whakakapi i te nuinga o ngā kirihou kei runga i te hinu. Ka taea te whakahaere i te tere pirau-koiora o ngā PHA mā te hanganga o ō rātou copolymers kia rite ki ngā hiahia tono rerekē.

Ko te āhuatanga nui o te PHA ko tōna kaha ki te pirau e ngā moroiti i roto i te nuinga o ngā taiao, pērā i te wairākau, te oneone, te wai moana, me ērā atu. Ko ngā hua i muri i te pirau he mea hanga ki te wai me te waro, ā, e kore e whakapoke i te taiao. Nā tēnei kitenga i ara ake ai te reo o te PHA i roto i te ao o ngā hua kirihou whakakorekore i raro i te papamuri o te aukati kirihou, ā, i whakarato hoki i tētahi whakaaro whanaketanga matomato me te pumau mō ngā hua whakakapinga kirihou tuatahi.
He rauemi pirau te PHA e whakamahi ana i te koiora whakahou hei rauemi mata, ā, ka hangaia katoatia e ngā moroiti; he tino pai te mahi a te PHA e pā ana ki te kore-paitini koiora, ā, he kirihou pirau kore-paitini, kāore hoki e taea te kai.
He painga motuhake anō hoki tō te hangarua me te maimoatanga o te PHA – ko ngā kirihou para tuku iho ka tukuna mā te whenua ururua, ka tahuna rānei, ka hua ake he raruraru parahanga pērā i te whenua me te hau. I tētahi atu taha, ka taea te tukatuka i te PHA mā roto i ētahi maimoatanga me te whakamahi hei whāngai hei whakaputa hua ōhanga anō, ka tutuki ai he huringa rua o te rauemi me te ōhanga.
