1.Polyethylene Terephthalate (PET kana PETE)
Iyi ndeimwe yemapurasitiki anonyanya kushandiswa.Yakareruka, yakasimba, inowanzo jeka uye inowanzoshandiswa mukurongedza chikafu uye machira (polyester).
Mienzaniso: Mabhodhoro ezvinwiwa, Mabhodhoro eChikafu/majagi (saladhi yekupfeka, nzungu ruomba, uchi, nezvimwewo) uye mbatya dzepolyester kana tambo.
2.High-Density Polyethylene (HDPE)
Pamwe chete, Polyethylene ndiyo mapurasitiki akajairika munyika, asi akaiswa mumhando nhatu: High-Density, Low-Density uye Linear Low-Density.High-Density Polyethylene yakasimba uye inopesana nekunyorova uye makemikari, izvo zvinoita kuti zvive zvakanaka kune makatoni, midziyo, pombi uye zvimwe zvekuvaka.
Mienzaniso: Makatoni emukaka, mabhodhoro ekugezesa, cereal box liner, matoyi, mabhaketi, mabhenji epaka uye pombi dzakasimba.
3.Polyvinyl Chloride (PVC kana Vinyl)
Iyi plastiki yakaoma uye yakaoma inopikisa makemikari uye mamiriro ekunze, zvichiita kuti ive inoshuviwa pakuvaka nekuvaka zvikumbiro;nepo chokwadi chekuti hachifambise magetsi chinoita kuti zvive zvakajairika kune zvemhando yepamusoro zvikumbiro, senge waya netambo.Inoshandiswawo zvakanyanya mumashandisirwo ekurapa nekuti haipindike kuhutachiona, inotapurwa nyore nyore uye inopa kushandiswa-kamwe-kushandisa kunoderedza hutachiona muhutano hwehutano.Padivi, tinofanira kucherechedza kuti PVC ndiyo ipurasitiki ine ngozi kune hutano hwevanhu, inozivikanwa kuburitsa chepfu ine njodzi mukati mehupenyu hwayo hwese (semuenzaniso: lead, dioxins, vinyl chloride).
Mienzaniso: Mapombi epombi, makadhi echikwereti, matoyi evanhu neemhuka dzinopfuyiwa, magata ekunaya kwemvura, mhete dzemazino, mabhegi emvura eIV uye tubing dzekurapa nemasiki eokisijeni.
4.Low-Density Polyethylene (LDPE)
Iyo yakapfava, yakajeka, uye inochinjika vhezheni yeHDPE.Inowanzo shandiswa se liner mukati memakatoni ezvinwiwa, uye munzvimbo inodzivirira corrosion yebasa uye zvimwe zvigadzirwa.
Mienzaniso: Purasitiki/kuputira, masangweji nemabhegi echingwa, kuputira, masaga emarara, masaga egirosari nemakapu ekunwiwa.
5.Polypropylene (PP)
Iyi ndeimwe yemhando dzakasimba dzepurasitiki.Inodzivirira kupisa kupfuura zvimwe, izvo zvinoita kuti ive yakanaka kune zvinhu zvakaita sekurongedza chikafu uye kuchengetedza chikafu chinogadzirwa kuti chibate zvinhu zvinopisa kana kudziisa pachayo.Inochinjika zvakakwana kubvumira kukotama kwakapfava, asi inochengeta chimiro chayo uye simba kwenguva yakareba.
Mienzaniso: Mashanga, zvivharo zvemabhodhoro, mabhodhoro emishonga, midziyo yezvokudya zvinopisa, tepi yekurongedzera, manapukeni anoraswa uye mabhokisi eDVD/CD (rangarirai izvozvo!).
6.Polystyrene (PS kana Styrofoam)
Iri nani inozivikanwa seStyrofoam, iyi purasitiki yakasimba inodhura-yakaderera uye inovhara zvakanyanya, izvo zvaita kuti ive huru mumaindasitiri ezvekudya, ekurongedza uye ekuvaka.Kufanana nePVC, polystyrene inoonekwa sepurasitiki ine ngozi.Inogona kuburitsa muchetura unokuvadza senge styrene (neurotoxin), iyo inogona kutorwa nyore nyore nechikafu uye nekudaro kumwiwa nevanhu.
Mienzaniso: Makapu, midziyo yekutakurisa chikafu, kutumira nekutakura zvigadzirwa, makatoni emazai, kucheka uye kuvharira chivako.
7.Zvimwe
Ah hongu, iyo yakashata "imwe" sarudzo!Ichi chikamu chekubata-zvese kune mamwe marudzi epurasitiki asiri emamwe emamwe mapoka matanhatu kana musanganiswa wemhando dzakawanda.Isu tinoisanganisira nekuti unogona kumbosangana ne#7 recycling kodhi, saka zvakakosha kuti uzive zvazvinoreva.Chinonyanya kukosha apa ndechekuti mapurasitiki aya haawanzo kudzokororwa.
Mienzaniso: Magirazi emaziso, mabhodhoro evana uye emitambo, zvemagetsi, maCD/DVD, zvigadziriso zvemwenje uye midziyo yepurasitiki yakajeka.
