Zvigadzirwa zvepurasitiki, sezvinhu zvakakosha muindasitiri yemazuva ano uye hupenyu hwezuva nezuva, zvine chikwereti chekushanda kwavo kune yavo yakasarudzika yemuviri nemakemikari zvimiro. Kuburikidza nekugadzirwa kwakasiyana-siyana kwemamolecular structural, mapurasitiki anogona kuita zvinodiwa zvakasiyana-siyana, kubva pakurongedzerwa kusingaremi kusvika pa{1}}mashandisirwo einjiniya esimba.
Chekutanga, basa repakati remapurasitiki riri muhuremu hwavo uye hunogara kwenguva refu. Density yavo yakadzikira pane yesimbi negirazi, ichideredza zvakanyanya mari yekufambisa. Anewo maitiro akanaka uye anodzivirira kuita ngura, zvichiita kuti akwanise kushandiswa kwenguva refu-mumaapplications akaita sedzimba dzemidziyo nemidziyo yemotokari. Semuenzaniso, polyethylene (PE) uye polypropylene (PP) zvave zvinhu zvemukati zvekurongedza chikafu uye zvinodiwa zvezuva nezuva nekuda kwekuchinjika kwavo uye kushomeka kwemakemikari.
Chechipiri, plastiki yepurasitiki inovapa maitiro akasiyana-siyana. Kuburikidza nekupisa kwemafuta kana kuumba jekiseni, mapurasitiki anogona kuumbwa kuita maumbirwo akaomarara kuti asangane nezvinodiwa zvekugadzirwa chaiko. Mapurasitiki einjiniya akadai sepolycarbonate (PC) nenaironi (PA) anochengetedza simba rawo kunyangwe patembiricha yakakwira uye anoshandiswa zvakanyanya mumidziyo yemagetsi nemakina. Uyezve, zvimiro zvavo zvekudzivirira zvinovaita zvinhu zvakakosha zvewaya, tambo, uye zvinhu zvemagetsi.
Kugadziriswa kwekushanda kunowedzera kuwedzera miganhu yekushandisa yemapurasitiki. Nekuwedzera zvinodzoreredza murazvo, simbi dzinosimbisa, kana biodegradable ingredients, mapurasitiki anogona kuwana hunyanzvi hwekuita sekudzivirira moto, kusimba, kana kugarisana kwezvakatipoteredza. Semuyenzaniso, bio{{2}mapurasitiki akaita sepolylactic acid (PLA) zvishoma nezvishoma ari kutsiva petroleum yechinyakare-yakavakirwa kuderedza kusvibiswa kwezvakatipoteredza.
Nekudaro, kushanda kwemapurasitiki kunopawo matambudziko, senge matambudziko eecological anokonzerwa nekuomerwa kwezvimwe zvinhu kuderera. Mune ramangwana, kuburikidza nehunyanzvi mune zvekushandisa sainzi uye tekinoroji, zvigadzirwa zvepurasitiki zvichatsvaga mhinduro yakadzikama pakati pekuita optimization uye budiriro inoenderera, ichienderera mberi nekutsigira zvakasiyana zvinodiwa munharaunda yemazuva ano.
