Kungani kufanele usebenzise amapulasitiki angaboli?
Ipulasitiki iyinto ebalulekile eyisisekelo. Ngokuthuthuka okusheshayo komnotho nomphakathi kanye nokuvela kwenani elikhulu lezimboni ezintsha ezifana ne-e-commerce, ukulethwa okucacile kanye nokuthatha, ukusetshenziswa kwemikhiqizo yepulasitiki kukhuphuka ngokushesha.
Ipulasitiki ayilethi nje kuphela ukunethezeka okukhulu empilweni yabantu, kodwa futhi idala “ukungcola okumhlophe”, okulimaza kakhulu imvelo nempilo yabantu.
I-China ibeke ngokucacile umgomo wokwakha iShayina enhle, futhi ukulawulwa "kokungcola okumhlophe" kuyisidingo sokuthuthukisa izinga lemvelo yemvelo nokwakha iShayina enhle.
Yini amapulasitiki angaboli?
Amapulasitiki awonakaliswa amapulasitiki awonakaliswa isenzo sama-microorganisms emvelweni, njengenhlabathi, inhlabathi enesihlabathi, imvelo yamanzi ahlanzekile, imvelo yamanzi olwandle kanye nezimo ezithile ezifana ne-composting noma i-anaerobic digestion, futhi ekugcineni yehliswe ngokuphelele ibe yi-carbon dioxide (CO2) noma / kanye ne-methane (CH4), amanzi (H2O) kanye nosawoti we-inorganicized wezakhi zawo, kanye ne-biomass entsha (njengama-microorganisms afile, njll.).
Yiziphi izigaba zamapulasitiki awonakele?
Ngokwe-Standard Guide for Classification kanye nokulebula kwemikhiqizo yepulasitiki eyonakalayo ehlelwe yi-China Federation of Light Industry, amapulasitiki awonakaliswayo anemikhuba ehlukene yokuwohloka enhlabathini, umquba, olwandle, emanzini ahlanzekile (imifula, imifula, amachibi) nakwezinye izindawo.
Ngokwezimo ezihlukene zemvelo, amapulasitiki awonakalayo angahlukaniswa abe:
Amapulasitiki awonakaliswa umhlabathi, amapulasitiki afaka umquba okonakaliswayo, imvelo yamanzi ahlanzekile amapulasitiki awonakaliswayo, amapulasitiki awonakaliswayo agaywe yi-anaerobic, amapulasitiki aqinile aqinile okugaywa kwe-anaerobic.
Uyini umehluko phakathi kwepulasitiki eyonakalayo kanye namapulasitiki ajwayelekile (okungaboli)?
Amapulasitiki endabuko ikakhulukazi enziwe nge-polystyrene, i-polypropylene, i-polyvinyl chloride nezinye izinhlanganisela ze-polymer ezinesisindo samangqamuzana angamakhulu ezinkulungwane kanye nesakhiwo samakhemikhali esizinzile, okunzima ukucekelwa phansi ngama-microorganisms.
Kuthatha iminyaka engu-200 kanye neminyaka engu-400 ukuthi amapulasitiki endabuko awonakaliswe endaweni yemvelo, ngakho-ke kulula ukubangela ukungcoliswa kwemvelo ngokulahla amapulasitiki endabuko ngokuthanda kwakhe.
Amapulasitiki angaboli ahluke kakhulu kumapulasitiki endabuko ekwakhiweni kwamakhemikhali. amaketanga abo amakhulu e-polymer aqukethe inani elikhulu lamabhondi e-ester, angagaywa futhi asetshenziswe ama-microorganisms, futhi ekugcineni abola abe ama-molecule amancane, angeke abangele ukungcola okuhlala njalo emvelweni.
Ingabe “izikhwama zepulasitiki ezivumelana nemvelo” ezivamile emakethe ziyabola?
Ngokwezidingo zokulebula ze-GB/T 38082-2019 “izikhwama zokuthenga zepulasitiki ezibolayo”, ngokuya ngokusetshenziswa okuhlukene kwezikhwama zokuthenga, izikhwama zokuthenga kufanele zimakwe ngokucacile “izikhwama zokuthenga zepulasitiki ezithintana ngqo nokudla” noma “ukuxhumana okungekona ukudla okuqondile. izikhwama zokuthenga zepulasitiki ezingaboli”. Ayikho ilogo "yesikhwama sepulasitiki esilungele imvelo".
Izikhwama zepulasitiki zokuvikela imvelo emakethe zingamaqhinga amaningi aqanjwa amabhizinisi egameni lokuvikelwa kwemvelo. Sicela uvule amehlo akho bese ukhetha ngokucophelela.
