polymer-ka ugu fiican-midka dheellitiraya sifooyinka jirka iyo waxqabadka deegaanka-ma jiro, laakiin polybutylene adipate co-terephthalate (PBAT) ayaa ka soo dhawaada kuwa badan.
Soosaarayaasha polymers-ka synthetic-ka ayaa muddo tobanaan sano ah ku guul darreystay in ay joojiyaan wax soo saarkooda in ay ku dhammaadaan meelaha qashinka ah iyo badaha, waxaana hadda la saaray cadaadis ah in ay qaadaan mas'uuliyadda.Qaar badan ayaa laban laabaya dadaallada lagu xoojinayo dib u warshadaynta si ay isaga difaacaan dhaleeceynta.Shirkado kale ayaa isku dayaya in ay wax ka qabtaan dhibaatada qashinka iyaga oo maalgashanaya balaastikada biodegradable-ka ah sida polylactic acid (PLA) iyo polyhydroxyalkanoate (PHA), iyaga oo rajaynaya xaalufka dabiiciga ahi in uu yareeyo ugu yaraan qaar ka mid ah qashinka.
Laakin dib u warshadaynta iyo biopolymers labaduba waxay wajahaan caqabado.In kasta oo sannado badan la dadaalay, heerka dib u warshadaynta balaastikada ee Maraykanka, tusaale ahaan, wali waa ka yar tahay 10%.Iyo bioopolymers-badanaa alaabada halsano-waxay u halgamayaan sidii ay u gaadhi lahaayeen wax qabad isku mid ah iyo cabirka wax soo saarka ee polymers-ka la sameeyay ee loogu talagalay in lagu badalo.
PBAT waxay isku daraysaa qaar ka mid ah sifooyinka faa'iidada leh ee polymers-ka synthetic iyo biobased.Waxaa laga soo qaatay batroolka caadiga ah - terephthalic acid (PTA), butanediol, iyo adipic acid - haddana waa biodegradable.Sida polymer synthetic, si sahal ah ayaa loo soo saari karaa baaxad weyn, waxayna leedahay sifooyinka jireed ee loo baahan yahay si loo sameeyo filimo dabacsan oo ka soo horjeeda kuwa caagadaha caadiga ah.
Sameeyaha PTA ee Shiinaha Hengli.Faahfaahinta ma cadda, shirkaddana lama heli karo faallo.Siidaynta warbaahinta iyo dhaqaalaha, Hengli waxay si kala duwan u sheegtay inay qorshaynayso 450,000 t warshad ama 600,000 t warshad loogu talagalay balaastikada noolaha.Laakiin marka la tilmaamayo alaabta loo baahan yahay maalgashiga, shirkadu waxay magacawday PTA, butanediol, iyo adipic acid.
Dahabka dahabiga ah ee PBAT ayaa ugu weyn Shiinaha.Qaybiyaha Kiimikada Shiinaha ee CHEMDO ayaa mashruucisa in wax soo saarka Shiinaha ee PBAT uu kor ugu kici doono ilaa 400,000 t sanadka 2022 laga bilaabo 150,000 t sanadka 2020.
