Ekuqaleni kokuvinjelwa kwepulasitiki, kufanele kube nenqwaba yezingane ezizibuzayo ukuthi iyini ipulasitiki ebolayo.Uyini umehluko phakathi kwepulasitiki eyonakaliswayo kanye nepulasitiki engaboli?Kungani sisebenzisa i-biodegradableumkhiqizo wepulasitiki?yiziphi izinzuzo zamapulasitiki angaboli? Ake sibheke imininingwane.

Amapulasitiki awonakaliswayo abhekisela ohlotsheni lwamapulasitiki izakhiwo zawo ezingahlangabezana nezidingo zokusetshenziswa futhi zihlale zingashintshile phakathi nesikhathi seshelufu, kodwa zingacekelwa phansi zibe izinto ezingenabungozi emvelweni ngaphansi kwezimo zemvelo zemvelo ngemva kokusetshenziswa.Ngakho-ke, amapulasitiki awonakaliswa imvelo.

Njengamanje, kunezinhlobo eziningi ezintsha zamapulasitiki: amapulasitiki abolayo, amapulasitiki abolayo, ukukhanya, amapulasitiki agaywa yi-oxidation / biodegradable, amapulasitiki abolayo asuselwa ku-carbon dioxide, amapulasitiki e-starch e-thermoplastic abolayo.Izikhwama zepulasitiki eziwohlokayo (okungukuthi, izikhwama zepulasitiki ezinobungani bemvelo) zenziwe ngezinto ze-polymer ezifanaI-PLA,PHA,PA,PBS.Isikhwama sepulasitiki esingaboli yendabuko senziwe ngepulasitiki ye-PE.

Izinzuzo zamapulasitiki awonakalayo:
Uma kuqhathaniswa namapulasitiki “odoti omhlophe” anganyamalala amakhulu eminyaka, ngaphansi kwezimo zokwenza umquba, imikhiqizo ebolayo ngokuphelele ingaboliswa ngama-microorganisms angaphezu kuka-90% phakathi kwezinsuku ezingu-30 futhi ingene emvelweni ngesimo se-carbon dioxide namanzi.Ngaphansi kwezimo zokungavundisi, ingxenye engalungiswanga yemikhiqizo ebolayo ngokuphelele yesikhungo sokuhlanza imfucuza izokwehla kancane kancane kungakapheli iminyaka emi-2.
Izikhwama zepulasitiki ezibolayo ngokuvamile zingabola phakathi nonyaka, kuyilapho ukuvikelwa kwemvelo kwama-Olympicamapayipi epulasitikiingaqala nokubola ezinsukwini ezingama-72 ngemuva kokulahlwa.Izikhwama zepulasitiki ezingaboli zithatha iminyaka engama-200 ukuze zilulazeke.

Kunezindlela ezimbili eziyinhloko zokusebenzisa amapulasitiki awonakalayo:

Enye insimu lapho kwakusetshenziswa khona amapulasitiki avamile.Kulezi zindawo, ubunzima bokuqoqa imikhiqizo yepulasitiki ngemuva kokusetshenziswa noma ukusetshenziswa kungabangela ukulimala kwemvelo, njengefilimu yepulasitiki yezolimo kanye nokupakishwa kwepulasitiki okulahlwayo.
Owesibili umkhakha wokushintsha ezinye izinto ngamapulasitiki.Ukusetshenziswa kwamapulasitiki awonakele kulezi zindawo kungaletha ukunethezeka, njengezinzipho zebhola zenkundla yegalofu kanye nezinto zokulungisa izithombo zokutshala amahlathi emvula ashisayo.

Ngezitolo ezinkulu, ukukhishwa, ukudla kanye nezinye izindawo ziye zasabela emigomeni yepulasitiki, zikhuthaza ngenkuthalo ukusetshenziswa kwemikhiqizo yepulasitiki ebolayo, umehluko phakathi kwamapulasitiki awonakele namapulasitiki angonakali kanye nezinzuzo zamapulasitiki awonakele nazo zinikezwa wonke umuntu.
Njengamanje, izinto eziningi ezithatha indawo yemikhiqizo yepulasitiki zisahlolwa.
