Eminyakeni yamuva, ngokuthuthuka okusheshayo komnotho, ukuphishekela kwabantu izinto ezibonakalayo nezingokomoya kuya ngokuya kukhuphuka, ukupakishwa kwemikhiqizo kunezidingo eziphakeme ngokulinganayo, lapho abantu bethenga imikhiqizo, ababheki nje ubuhle bephakheji, kodwa futhi bacabangele izinhlobonhlobo zeminye imisebenzi.Kungenxa yokuthuthuka okuqhubekayo kokuphishekela kwabantu ukupakisha umkhiqizo, izinto eziningi ezintsha zokupakisha ziyaqhubeka nokusetshenziswa ekufakweni komkhiqizo.
Kungani sithuthukisa izinto ezingaboli
Izinto ze-polymer zokwenziwa zinezinzuzo zesisindo esincane, amandla aphezulu, ukuzinza okuhle kwamakhemikhali kanye nenani eliphansi, ngensimbi, izinkuni, usimende isibe yizinsika ezine zomnotho wezwe, isetshenziswa kabanzi ekupakishweni komkhiqizo.Kodwa-ke, inani elikhulu lemfucuza ngemva kokusetshenziswa kwalo liyakhula usuku nosuku, libe umthombo wokungcola okumhlophe, ukulimala okukhulu emvelweni, okuholela ekungcoleni kwamanzi nenhlabathi, ukulimala ekusindeni komuntu kanye nempilo, ekusindeni kwemvelo komuntu kubangele isimo esibi. umthelela awukwazi ukuzitshwa.
Ngaphezu kwalokho, ukukhiqizwa kwezinto zokwenziwa ze-polymer -- impahla eluhlaza ye-petroleum ihlala iphelile usuku olulodwa, ngakho-ke kuyaphuthuma ukuthola izinto ezintsha ezihambisana nemvelo, ukuthuthukiswa kwama-polymers angenawo uphethiloli, kanye nezinto ezibolayo kuyindlela ephumelelayo ukuxazulula le nkinga.
Incazelo yezinto ezibolayo
Izinto ezibolayo ezibolayo, ezaziwa nangokuthi "izinto eziluhlaza zemvelo", zibhekisela ezintweni ezingase ziwohloke ngaphansi kwesenzo sezinto ezincane eziphilayo kanye nama-enzyme.Ngokuqondile, kusho ukuthi ngaphansi kwezimo ezithile, kungaholela ekwakhiweni kwezinto eziphilayo ze-polymer ngaphansi kwesenzo samagciwane, isikhunta, i-algae nezinye izinambuzane zemvelo.
Indlela efanelekile yokucekela phansi
I-biodegradable material ekahle iwuhlobo lwe-polymer esebenza kahle kakhulu, engaboliswa ngokuphelele amagciwane emvelo ngemva kokulahlwa, futhi ekugcineni iguqulwe ibe yi-CO2 ne-H2O, eba yingxenye yomjikelezo wekhabhoni emvelweni.
