Kwa zaka zambiri, njira yayikulu yobwezeretsanso mapulasitiki ndi makina obwezeretsanso, omwe nthawi zambiri amasungunula zidutswa zapulasitiki ndikuzipanga tinthu tatsopano.Ngakhale kuti zipangizozi zidakali zofanana ndi ma polima apulasitiki, nthawi zawo zobwezeretsanso zimakhala zochepa, ndipo njirayi imadalira kwambiri mafuta opangira mafuta.
Pakali pano, mapulasitiki zinyalala ku China makamaka monga pulasitiki filimu, waya pulasitiki ndi nsalu nsalu, mapulasitiki thovu, pulasitiki ma CD mabokosi ndi muli, tsiku ntchito mankhwala pulasitiki (mabotolo pulasitiki, zovekera chitoliro,zotengera zakudya, etc.), matumba apulasitiki ndi mafilimu apulasitiki aulimi.Komanso, kumwa pachaka kwamapulasitiki a magalimotoku China wafika matani 400000, ndi kumwa pachaka mapulasitiki kwazida zamagetsindipo zida zapakhomo zafikira matani oposa 1 miliyoni.Zogulitsazi zakhala chimodzi mwazinthu zofunika kwambiri zopangira zinyalala zamapulasitiki pambuyo pochotsa.
Masiku ano, chidwi chowonjezereka chikuperekedwa pakubwezeretsa mankhwala.Kubwezeretsanso kwa Chemical kumatha kusintha mapulasitiki kukhala mafuta, zopangira zamafuta a petrochemical komanso ngakhale ma monomers.Sizingangobwezeretsanso zinyalala zambiri zamapulasitiki, komanso kuchepetsa kudalira mafuta oyaka.Ngakhale kuteteza chilengedwe ndi kuthetsa vuto la kuipitsidwa kwa pulasitiki, kungathenso kuchepetsa mpweya wa carbon.
Mumatekinoloje ambiri apulasitiki obwezeretsa mankhwala, ukadaulo wa pyrolysis nthawi zonse umakhala wotsogola.M'miyezi yaposachedwa, malo opangira mafuta a pyrolysis ku Europe ndi America afalikira mbali zonse za Atlantic.Mapulojekiti atsopano okhudzana ndi ukadaulo wopangira utomoni akupanganso, omwe anayi ndi mapulojekiti a polyethylene terephthalate (PET), onse omwe ali ku France.
Poyerekeza ndi kuchira kwamakina, chimodzi mwazinthu zofunikira pakuchira kwamankhwala ndikuti amatha kupeza mtundu wa polima wapachiyambi komanso kuchira kwapulasitiki.Komabe, ngakhale kuchira kwa mankhwala kungathandize kukonzanso chuma cha pulasitiki, njira iliyonse ili ndi zofooka zake ngati iyenera kugwiritsidwa ntchito pamlingo waukulu.
Zinyalala za pulasitiki sikuti ndi vuto loipitsa dziko lonse lapansi, komanso ndi zinthu zokhala ndi mpweya wambiri, zotsika mtengo komanso zitha kupezeka padziko lonse lapansi.Chuma chozungulira chakhalanso chitsogozo chamtsogolo chamakampani apulasitiki.Ndi kupititsa patsogolo ukadaulo wothandizira, kuchira kwamankhwala kumawonetsa chiyembekezo chabwino chazachuma.
