Plastic arung arai ni gaw n-gun n law ai, ngang grin ai, manu n law ai majaw shani shagu na sak hkrung lam hte bungli galaw ai lam ni hta grai lang ma ai. Raitim, plastic nhprang arai ni hpe n tara ai hku kabai kau ai gaw grup yin hpe grai hkra machyi shangun nga ai. Dai majaw, plastic arung arai ni hpe hpaji masa hku garan ginhka ai lam gaw, sut masa hpe bai jai lang ai lam hte grup yin hpe makawp maga ai lam a matu ahkyak nga ai.
Mungkan madang hku yu yang, plastic arung arai ni hpe madung hku nna garan nna, langai hte langai hta n bung ai chemical composition hte bai jai lang mai ai atsam ni nga ai. Shawng nnan na hpan gaw PET (polyethylene terephthalate) rai nna, lu sha ntsin htung ni hta lang ai, asan sha mu lu ai hte loi loi hte bai jai lang mai ai. Lahkawng ngu na hpan gaw HDPE (high-density polyethylene) rai nna, hka htung hte hka shin tsi ni hta lang ai, n-gun ja ai hte tsi mawan ni hpe ninghkap lu ai atsam nga ai. Masum ngu na hpan gaw PVC (polyvinyl chloride) rai nna, dai hpe pipe hte plastic film ni hta lang ai raitim, chlorine lawm ai majaw, bai jai lang na matu yak hkak ai. Mali ngu na daw gaw LDPE (low-density polyethylene) rai nna, plastic htinggaw ni hte plastic shingnip ni hta lang ai, n-gun n rawng ai hku nna laklai nga ai. Manga ngu na hpan gaw PP (polypropylene) rai nna, malu masha bang ai hka htung ni hte mawdaw arung arai ni hta lang ai rai nna, nbung katsi ai hpe hkam sharang lu ai hte bai lang mai ai atsam nga ai. Lahkawng ngu na hpan gaw PS (polystyrene) rai nna, foam tableware hte shingbyi shara ni hta lang ai rai nna, n-gun n law tim, n-gun yawm mat na matu yak ai. Sanit ngu na daw gaw kaga plastic ni rai nna, dai hta PC (polycarbonate) zawn re ai engineering plastic ni lawm ai, dai ni hpe electronic hte tsi mawan ni hta lang ai.
Plastic arung arai ni hpe hpaji masa hku garan ginhka ai gaw, bai jai lang ai lam hpe grau kaja hkra galaw ya ai sha n-ga, grup yin hpe mung awu asin di kau ya lu ai. Ga shadawn, PET hte HDPE ni hpe bai jai lang ai lam grai law ai majaw, garan nna bai jai lang ai hku nna, fiber (sh) container ni de bai jai lang mai ai. Raitim, PVC hte PS hta hkrit tsang hpa arung arai ni lawm ai majaw laksan hku nna hparan ra ai. Plastic arung arai ni hpe garan ginhka ai lam, kabai kau ai shaloi, arung arai ni hte garan ginhka ai lam, buga masha ni a bai jai lang ai ladat ni hte rau jawm galaw ai lam ni hpe mung, jai lang ai ni grau chye na ra ai.
Htawm hpang de, n-gun n rawng ai plastic ni hte bai jai lang mai ai hpaji masa ni rawt jat wa ai hte maren, plastic ni hpe garan ginhka ai lam hte hparan ai lam ni hpe grau nna gram lajang wa na re. Policy lam matsun, hpaji masa ningnan ni hpe gyin shalat ai, mung shawa ni shanglawm ai hku nna, plastic arung arai ni hpe garan ginhka nna bai jai lang ai lam gaw grau ngang grin ai rawt jat lam de sit sa wa nna, mungkan a shingra tara hpe makawp maga na matu karum ya na re.
