Njengomba ophambili wokuphucula umgangatho wobomi,izixhobo zekhayabanethemba elibanzi lophuhliso.Ngokunyuka okuqhubekayo komvuzo wesizwe olahlwayo kunye nokuphuculwa kobume bokusetyenziswa, iye yaba yindlela entsha yokuqhawula izixhobo zekhaya ezilahlwayo kunye nokukhupha inkunkuma enobungozi ikakhulu kubandakanywa iibhodi zesekethe eziprintiweyo, umgubo wefluorescent, iglasi ekhokelayo kunye ne-oyile yenjini, kunye nenkunkuma eqinileyo. ingakumbi iplastiki, intsimbi, ubhedu kunye nealuminiyam.
Ukususela ngo-2009, i-China iye yabhengeza iMithetho yoLawulo lweNkunkuma yoMbane kunye neeMveliso zoMbane (uMmiselo we-551 weBhunga kaRhulumente).Abavelisi beemveliso zombane, abathumeli beemveliso zombane kunye nee-arhente zabo baya kuthi, ngokuhambelana nemithetho nemigaqo efanelekileyo, bahlawule imali yokulahlwa kwenkunkuma yeemveliso zombane.” “Urhulumente ukhuthaza abavelisi be-elektroniki kunye nombane ukuba baphinde basebenziseke bodwa okanye ngokuphathisa abasasazi, ii-arhente zogcino, ii-arhente zenkonzo emva kokuthengiswa, kwaye bachithe abahlaziyi bezixhobo zombane.”
Ngokwezibalo, okwangoku, i-100 yezigidi ukuya kwi-120 yezigidi zezixhobo zasemakhaya zichithwa ngonyaka e-China, ngokunyuka malunga ne-20%.Kuqikelelwa ukuba inani lilonke lezixhobo zasekhaya ezilahliweyo eTshayina kulindeleke ukuba lifikelele kwi-137 yezigidi kulo nyaka.Umthamo omkhulu kangaka ubonakala ukruqula, kodwa amashishini amaninzi ayanuka amathuba oshishino.
Imigaqo-nkqubo encomekayo yenze intsingiselo yeeplastiki ezisetyenziswe ngokutsha ezilungele imeko-bume yaphumelela.Amashishini ohlobo lwabathengi akhuphe imfuno enkulu yokusebenzisa iiplastiki ezisetyenzisiweyo, kwaye abathengi bayaziqhenya ngokutya iimveliso zeplastiki ezisetyenzisiweyo.Uyilo oluphambili, oluqhuba uphuhliso lulonke lweshishini.
Ubungakanani bemarike yombane kunye neeplastiki ezisetyenziswe ngokutsha
Umthamo wokulahlwa kwenkunkuma yombane kunye neemveliso zombane e-China unyuke ngokuthe ngcembe, kwaye isikali sentengiso kunye namandla entengiso kushishino lokulahla makhulu.Iplastiki yinxalenye ebalulekileyo yenkunkuma yombane kunye neemveliso zombane.Inkunkuma ichaza malunga ne-30-50% yazo zonke iintlobo zenkunkuma yombane kunye neemveliso zombane.Ngokusekwe kulo mlinganiso, isikali sentengiso yeplastiki yenkunkuma yesixhobo sasekhaya esinoomatshini abane kuphela kwaye ingqondo enye inokufikelela kwi-2 yezigidi zeetoni ngonyaka, kwaye ngokupheliswa kwezixhobo zasendlini eziphelelwe lixesha, ukuphinda kusetyenziswe iiplastiki zenkunkuma yendlu kuya kuzisa indawo enkulu. imarike eyongezelelweyo.
Eyona nkunkuma iphambili yeplastiki kwinkunkuma yombane kunye neemveliso zombane ikakhulu ziquka: acrylonitrile butadiene styrene.(ABS),i-polystyrene (PS), i-polypropylene (PP), i-polyvinyl chloride (PVC), i-polycarbonate(PC), njl. Phakathi kwabo, i-ABS kunye ne-PS zisetyenziswa ngokuqhelekileyo ekwenzeni iilayini, iipaneli zomnyango, iigobolondo, njl., kunye noluhlu olukhulu lokusetyenziswa kunye nokusetyenziswa.Imakethi eyongezelekayo kwixesha elizayo iya kubonelela ngamathuba amaninzi kwi-ABS kunye ne-PS recycled imathiriyeli.
