Zopangidwa ndi pulasitiki zimagwiritsidwa ntchito kwambiri pamoyo watsiku ndi tsiku komanso m'mafakitale chifukwa cha kupepuka, kulimba, komanso zotsika mtengo-zochita zake. Komabe, kutaya kosayenera kwa zinyalala zapulasitiki kumawononga kwambiri chilengedwe. Chifukwa chake, gulu lasayansi lazinthu zamapulasitiki ndizofunikira pakubwezeretsanso zinthu komanso kuteteza chilengedwe.
Malinga ndi miyezo yapadziko lonse lapansi, zinthu zapulasitiki zimagawika m'magulu asanu ndi awiri, gulu lililonse lili ndi mitundu yosiyanasiyana yamankhwala komanso mawonekedwe obwezeretsanso. Gulu loyamba ndi PET (polyethylene terephthalate), yomwe imagwiritsidwa ntchito kwambiri m'mabotolo a zakumwa, zowonekera komanso zosavuta kuzibwezeretsanso. Gulu lachiwiri ndi HDPE (high-polyethylene yochuluka kwambiri), yomwe imagwiritsidwa ntchito m'mabotolo a mkaka ndi zotsukira, ndipo imadziwika ndi mphamvu zake komanso kusagwira ntchito kwamankhwala. Gulu lachitatu ndi PVC (polyvinyl chloride), yomwe imagwiritsidwa ntchito popanga mapaipi ndi filimu yapulasitiki, koma yokhala ndi chlorine, zomwe zimapangitsa kuti zikhale zovuta kuzikonzanso. Gulu lachinayi ndi LDPE (lotsika-polyethylene yotsika), yomwe imagwiritsidwa ntchito m'matumba apulasitiki ndi zokutira zapulasitiki, ndipo imadziwika ndi kusinthasintha kwake. Gulu lachisanu ndi PP (polypropylene), lomwe limagwiritsidwa ntchito kwambiri muzotengera zakudya ndi zida zamagalimoto, zomwe zimadziwika ndi kukana kwake kutentha komanso kusinthikanso. Gulu lachisanu ndi chimodzi ndi PS (polystyrene), lomwe limagwiritsidwa ntchito popanga thovu ndi zida zonyamula, zomwe ndizopepuka koma zovuta kuzitsitsa. Gulu lachisanu ndi chiwiri ndi mapulasitiki ena, kuphatikiza mapulasitiki a engineering ngati PC (polycarbonate), omwe amagwiritsidwa ntchito kwambiri pamagetsi ndi zida zamankhwala.
Kuyika zinthu zapulasitiki mwasayansi sikungothandiza kukonza zobwezeretsanso komanso kumachepetsa kuwononga chilengedwe. Mwachitsanzo, PET ndi HDPE ali ndi mitengo yobwezeretsanso kwambiri ndipo amatha kubwezerezedwanso kukhala ulusi kapena zotengera kudzera muzobwezeretsanso padera. Komabe, PVC ndi PS zili ndi zinthu zowopsa ndipo zimafunikira chisamaliro chapadera. Ogula akuyeneranso kudziwa bwino za kufunikira kosankha zinthu zapulasitiki, kuzilekanitsa pozitaya, komanso kugwirizana ndi njira zobwezeretsanso zinthu m'deralo.
M'tsogolomu, ndi kupita patsogolo kwa mapulasitiki osawonongeka ndi matekinoloje obwezeretsanso, magulu apulasitiki ndi kasamalidwe kadzakhala koyengedwa kwambiri. Kupyolera mu chitsogozo cha ndondomeko, luso lazopangapanga, ndi kutenga nawo mbali kwa anthu, kugawa ndi kubwezeretsanso zinthu zapulasitiki zidzapita ku njira yachitukuko yokhazikika, zomwe zimathandizira kuteteza chilengedwe cha Dziko Lapansi.
