Kupyolera mu kuyesetsa kosalekeza kwa mibadwo ingapo ya akatswiri a zamankhwala ndi mainjiniya, mapulasitiki opangidwa kuchokera ku petroleum, malasha, ndi gasi achilengedwe akhala zida zofunika kwambiri pamoyo watsiku ndi tsiku chifukwa cha kulemera kwake, kulimba, kukongola, ndi mtengo wotsika.Komabe, ndizo zabwino izi za pulasitiki zomwe zimadzetsanso zinyalala zambiri zapulasitiki.Pulasitiki ya Post-consumer recycling (PCR) yakhala imodzi mwa njira zofunika kwambiri zochepetsera kuwonongeka kwa chilengedwe cha pulasitiki ndikuthandizira makampani opanga mphamvu ndi mankhwala kuti apite ku "kusalowerera ndale kwa carbon".
Ma resins a Post-consumer recycled (PCR) amapangidwa kuchokera ku zinyalala zapulasitiki zomwe zimatayidwa ndi ogula.Mapulastiki atsopano amapangidwa potolera zinyalala za pulasitiki kuchokera mumtsinje wobwezeretsanso ndikudutsa posankha, kuyeretsa, ndi kupanga ma pelleting a makina obwezeretsanso.Ma pellets atsopano apulasitiki amakhala ndi mawonekedwe ofanana ndi apulasitiki asanabwezeretsedwe.Pamene mapepala apulasitiki atsopano amasakanikirana ndi utomoni wa namwali, mitundu yosiyanasiyana ya pulasitiki yatsopano imapangidwa.Mwanjira iyi, sikuti amachepetsa mpweya woipa wa carbon dioxide, komanso amachepetsa mphamvu zamagetsi.
