Ukuthuthukiswa kwalolu bhubhane sekulethe imikhiqizo yepulasitiki efana nezifihla-buso, izingubo zokuzivikela kanye nezibuko emehlweni abantu futhi.Isho ukuthini ipulasitiki endaweni ezungezile, kubantu, emhlabeni, futhi kufanele siwaphathe kanjani amapulasitiki ngendlela efanele?
Umbuzo 1: kungani usebenzise ipulasitiki engaka esikhundleni sezinye izinto zokupakisha?
Ezikhathini zasendulo, ukudla kwakungapakishwa kahle futhi kwakudingeka kudliwe noma kuphulwe.Uma ungakwazi ukunqoba inyamazane yakho namuhla, kuzodingeka ulambe.Kamuva, abantu bazama ukusonga nokugcina ukudla ngamahlamvu, amabhokisi okhuni, amaphepha, amathini obumba, njll., kodwa kwakulula ukuhamba ibanga elifushane kuphela.Ukusungulwa kwengilazi ngekhulu le-17 kwenza abantu babe nezithiyo ezinhle zokupakisha.Nokho, izindleko eziphakeme cishe zitholakala kuphela kwabasebukhosini.Ukusungulwa kanye nokusetshenziswa kwezinga elikhulu kwamapulasitiki ekhulwini lama-20 kwenze abantu bakwazi ukwazi izinto zokupakisha ezingabizi ngempela ezinomgoqo omuhle futhi okulula ukuwenza.Kusukela ekushintsheni amabhodlela ezingilazi kuya ezikhwameni zokupakisha ezithambile kamuva, amapulasitiki aqinisekisa ukuthi ukudla kungathuthwa ngenani elibanzi lezindleko eziphansi, andise ngokuphumelelayo isikhathi seshelufu, kunciphise izindleko zokuthola ukudla, futhi kuzuze amakhulu ezigidi zabathengi.Namuhla, sisebenzisa amashumi ezigidi zamathani amapulasitiki epulasitiki ngonyaka, esikhundleni salokho ingilazi noma iphepha, ingasaphathwa eyokunyuka kwezindleko zokucubungula, izinto ezidingekayo ziyisayensi yezinkanyezi.Isibonelo, uma ubisi emasakeni ase-aseptic esikhundleni sebhodlela lengilazi, impilo yeshalofu izofinyezwa kusukela ngonyaka owodwa kuya ezinsukwini ezintathu, futhi isisindo sephakheji sizokwandisa izikhathi eziningi.Ukusetshenziswa kwamandla okudingekayo ngesikhathi sokuthutha ukukhuphuka kweNombolo yejometri.Ukwengeza, ukwakhiwa nokugaywa kabusha kwezingilazi nemikhiqizo yensimbi kudinga ukusetshenziswa kwamandla kakhudlwana, futhi ukukhiqizwa kwephepha nokugaywa kabusha kudinga inani elikhulu lamanzi namakhemikhali.Ngaphandle kokuxazulula inkinga yokugcinwa kokudla, ukuvela kwemikhiqizo yepulasitiki kuye kwakhuthaza nokuthuthukiswa kwezimoto, izingubo zokugqoka, amathoyizi, izinto zasendlini nezinye izimboni.ikakhulukazi ngezinjongo zokwelapha, njengezifihla-buso, izingubo zokuzivikela, izibuko, ukuze sisivikele egciwaneni.
Umbuzo 2: yini engalungile ngepulasitiki?
Ipulasitiki inhle kakhulu ukusebenzisa abantu abaningi, kodwa ngemva kokuyisebenzisa?Ngenxa yokuntuleka kwezindawo zokwelapha ezihambisanayo ezindaweni eziningi, amanye amapulasitiki alahlwa endaweni ezungezile, futhi ngisho nengxenye encane yesiqhingi sikadoti wepulasitiki yakheka ekujuleni kolwandle njengoba umfula ungena olwandle.Kubeka engozini enkulu abanye ozakwethu kulo mhlaba.Izinguquko ekuziphatheni kwabathengi nazo zinomthelela ekwakhekeni kwalezi mfucumfucu zepulasitiki.Okufana nokukhipha, ukulethwa okucacile, lezi zilula kakhulu izimpilo zethu, kodwa futhi zenza ukukhiqizwa kwamapulasitiki angcolile kwande.Ngenkathi sijabulela ukunethezeka kwamapulasitiki, kufanele futhi Sicabangele ukuthi ingeyakuphi ngemuva kokusetshenziswa.
Umbuzo 3: kungani inkinga yepulasitiki engcolile ingazange ikhathazeke kangako eminyakeni edlule?
Kunochungechunge lwezimboni ekugayweni kabusha kwepulasitiki emhlabeni, ngokuyisisekelo amazwe athuthukile ahlukanisa ukugaywa kabusha kwepulasitiki futhi akuthengisele amazwe asathuthuka ngamanani aphansi, azuza ngokulungisa amapulasitiki agaywe kabusha.Kodwa-ke, uhulumeni waseShayina wakuvala ukungeniswa kwemfucuza eqinile ekuqaleni kuka-2018, namanye amazwe asathuthuka alandela lokho, ngakho-ke amazwe kufanele abhekane namapulasitiki awo alahlwayo.
Khona-ke, akuwona wonke amazwe analezi ngqalasizinda eziphelele.Ngenxa yalokho, imfucuza plastic kanye nezinye udoti ndawonye akukho lapho ungaya khona, okubangela izinkinga ezithile kwezenhlalo, kodwa futhi wakhanga kakhulu wonke umuntu Ukukhathazeka.
Umbuzo 4: amapulasitiki kufanele agaywe kabusha kanjani?
Abanye abantu bathi thina bantu singabathwali bemvelo kuphela, nopulasitiki kufanele babuyele emuva lapho bevela khona.Kodwa-ke, amapulasitiki ngokuvamile athatha izinkulungwane zeminyaka ukuwohloka ngokuphelele.Kuwubuwula ukushiya lezi zinkinga ezizukulwaneni ezizayo.Ukugaywa kabusha akuncikile emthwalweni wemfanelo, noma othandweni, kodwa embonini.Imboni yokugaywa kabusha engenza abantu bacebe, bacebe futhi bacebe iwumsuka wokuxazulula inkinga yokugaywa kabusha.
Ngaphezu kwalokho, ungasebenzisi amapulasitiki angcolile njengodoti.Kuwudoti ukukhipha uwoyela, ukuwahlephula abe ama-monomers, ukuwenza polymerize abe amapulasitiki, bese uwacubungula kube imikhiqizo ehlukahlukene.
Umbuzo 5: yisiphi isixhumanisi esibaluleke kakhulu ukuthi sisetshenziswe kabusha?
Kumele ihlukaniswe!
1. hlukanisa ipulasitiki kwenye imfucuza kuqala;
2. amapulasitiki ahlukene ngokwezinhlobo ezahlukene;
3. ukuhlanza ukuguqulwa kwe-granulation ngezinye izinjongo.
Isinyathelo sokuqala senziwa ochwepheshe bokuqoqwa kwemfucuza, kanti esesibili senziwa isitshalo esikhethekile sokuchotshozwa nokuhlanza.Manje kunamarobhothi kanye nobuhlakani bokwenziwa kanye nokufunda okujulile kungaphatha ngokuqondile izinyathelo zokuqala nezesibili.Ikusasa selifikile.Uzoza?Mayelana nesinyathelo sesithathu, wamukelekile ukuqhubeka nokusinaka.
Umbuzo 6: yimaphi amapulasitiki alahlwayo okunzima ukuwagaya kabusha?
Kukhona ukusetshenziswa okuningi kwamapulasitiki, amabhodlela ajwayelekile esiphuzo samanzi amaminerali yi-PET, amabhodlela e-HDPE okugeza e-shampoo, ayizinto zodwa, kulula ukuzisebenzisa kabusha.Ukupakishwa okuthambile okufana nokokugeza, ukudla okulula, izikhwama zelayisi, okusekelwe kusithiyo kanye nezidingo zemishini, kuvame ukuqukatha i-PET, inayiloni ne-PE nezinye izinto, azihambelani, ngakho akulula ukuzigaya kabusha.
Umbuzo 7: amaphakheji athambile angenziwa kanjani kabusha kalula?
Ukupakisha okuguquguqukayo, okunezinhlaka eziningi futhi okuqukethe amapulasitiki ezinto ezihlukene, yikhona okunzima kakhulu ukugaywa kabusha ngoba lawa mapulasitiki ahlukene awahambisani.
Ngokuya ngedizayini yokupakisha, into eyodwa iyona evumela kakhulu ukugaywa kabusha.
I-CEFLEX yase-Europe kanye ne-APR e-United States yenze izindinganiso ezihambisanayo, futhi ezinye izinhlangano zezimboni e-China nazo zisebenza ngezindinganiso ezifanele.
Ngaphezu kwalokho, ukugaywa kabusha kwamakhemikhali nakho kuyakhathaza.
