Ekuqaleni kokuthintelwa kokusetyenziswa kweplastiki, kufuneka ukuba kukho abantwana abaninzi abazibuza ukuba yintoni iplastiki ebolayo. Yintoni umahluko phakathi kweplastiki ebolayo kunye neplastiki engonakalisiyo? Kutheni sisebenzisa ebolayoimveliso yeplastikiZithini iingenelo zeplastiki ezibolayo? Makhe sijonge iinkcukacha.

Iiplastiki ezibolayo zibhekisa kuhlobo lweeplastiki ezineempawu ezinokuhlangabezana neemfuno zokusetyenziswa kwaye zingatshintshi ngexesha lokuphelelwa kwazo, kodwa zinokonakala zibe zizinto ezingenabungozi kwindalo phantsi kweemeko zendalo emva kokusetyenziswa. Ke ngoko, ziiplastiki ezibolayo kwindalo.

Okwangoku, kukho iintlobo ezininzi ezintsha zeplastiki: iiplastiki ezibolayo, iiplastiki ezibolayo, ukukhanya, iiplastiki ezibolayo/ezibolayo, iiplastiki ezibolayo ezisekelwe kwikhabhoni dayoksayidi, iiplastiki ezibolayo zesitatshi se-thermoplastic resin. Iingxowa zeplastiki ezibolayo (oko kukuthi, iingxowa zeplastiki ezinobuhlobo nokusingqongileyo) zenziwe ngezinto zepolymer ezifanaI-PLA,PHAs,PA, PBS. Ingxowa yeplastiki yesintu engonakalisiyo yenziwe ngeplastiki ye-PE.

Iingenelo zeplastiki ezibolayo:
Xa kuthelekiswa neeplastiki “zenkunkuma emhlophe” ezinokunyamalala kangangeminyaka engamakhulu, phantsi kweemeko zomgquba, iimveliso ezinokubola ngokupheleleyo zinokubola ngaphezulu kwe-90% yeentsholongwane ezincinci kwiintsuku ezingama-30 kwaye zingene kwindalo ngendlela ye-carbon dioxide namanzi. Phantsi kweemeko ezingezizo zomgquba, inxalenye enganyangwanga yeemveliso ezinokubola ngokupheleleyo zesityalo sonyango lwenkunkuma iya konakala kancinci kancinci kwiminyaka emi-2.
Iingxowa zeplastiki ezibolayo ngokubanzi zinokubola kungekapheli nonyaka, ngelixa ukhuseleko lokusingqongileyo kwiOlimpikiiifuneli zeplastikiingaqala ukubola emva kweentsuku ezingama-72 emva kokulahlwa. Iingxowa zeplastiki ezingaboliyo zithatha iminyaka engama-200 ukuba zibole.

Kukho iindlela ezimbini eziphambili zokusebenzisa iiplastiki ezibolayo:

Enye yindawo apho kwakusetyenziswa khona iiplastiki eziqhelekileyo. Kwezi ndawo, ubunzima bokuqokelela iimveliso zeplastiki emva kokusetyenziswa okanye ukusetyenziswa bunokubangela umonakalo kwindalo esingqongileyo, njengefilimu yeplastiki yezolimo kunye nokupakishwa kweplastiki elahlwayo.
Okwesibini kukutshintsha ezinye izinto ngeplastiki. Ukusetyenziswa kweplastiki ebolayo kwezi ndawo kunokuzisa lula, njengezikhonkwane zebhola kwiindawo zokudlala igalufa kunye nezixhobo zokubopha izithombo zokulima amahlathi emvula ashushu.

Njengoko iivenkile ezinkulu, ukutya okuya kuthathwa, ukutya kunye nezinye iindawo zisabela kwimiqathango yeplastiki, zikhuthaza ukusetyenziswa kweemveliso zeplastiki ezinokubola, umahluko phakathi kweeplastiki ezinokubola kunye neeplastiki ezingabola kunye neengenelo zeplastiki ezinokubola nazo zibonelelwa kuye wonke umntu.
Okwangoku, kusakhangelwa izinto ezininzi ezithatha indawo yeemveliso zeplastiki.
