Sechinhu chakakosha chekuvandudza hupenyu hwehupenyu,midziyo yemumbavane tarisiro yakafara yebudiriro.Nekuenderera mberi kwekuwedzera kwemari inoraswa nenyika uye nekukwidziridzwa kwemaitiro ekushandisa, yave tsika nyowani yekubvisa midziyo yemumba uye kubvisa tsvina ine njodzi kunyanya inosanganisira akadhindwa edunhu mabhodhi, fluorescent poda, girazi re lead nemafuta einjini, pamwe nemarara akaomarara. kunyanya kusanganisira mapurasitiki, simbi, mhangura nealuminium.
Kubva 2009, China yakazivisa Mitemo pamusoro peKutungamirirwa kweKudzokororwa kweWaste Electrical and Electronic Products (Chirevo Nhamba 551 yeHurumende yeHurumende).Vagadziri vezvigadzirwa zvemagetsi, vatakuri vezvigadzirwa zvemagetsi zvinotengeswa kunze kwenyika nevamiriri vavo, zvinoenderana nemitemo nemirau yakakodzera, kubhadhara mari yekurasa yezvakaraswa zvigadzirwa zvemagetsi.” “Hurumende inokurudzira vagadziri vemagetsi nemagetsi kuti vadzokorore vari voga kana nekupa vanogovera, masangano ekuchengetedza, masangano ebasa mushure mekutengesa, uye kutambisa midziyo yemagetsi zvakare.
Zvinoenderana nenhamba, parizvino, 100 miriyoni kusvika 120 miriyoni marara midziyo yemumba inobviswa gore rega muChina, nekuwedzera kwe20%.Zvinofungidzirwa kuti huwandu hwemidziyo yemumba yakaraswa muChina inotarisirwa kusvika 137 miriyoni gore rino.Vhoriyamu yakakura kudaro inoita seinofinha, asi mabhizinesi mazhinji anonhuwirira mikana yebhizinesi.
Mitemo yakanaka yakaita kuti maitiro emapurasitiki akadzokororwa abudirire.Mabhizinesi emhando yevatengi akaburitsa kudiwa kukuru kwekushandisa mapurasitiki akadzokororwa, uye vatengi vanodada nekudya zvigadzirwa zvepurasitiki zvakare.Inotungamira dhizaini, ichityaira kukura kwese kweindasitiri.
Chiyero chemusika wemagetsi nemagetsi akadzokororwa mapurasitiki
Huwandu hwekuraswa kwemarara emagetsi nezvigadzirwa zvemagetsi muChina hwakwira zvishoma nezvishoma, uye chiyero chemusika uye mukana wemusika weindasitiri yekurasa yakakura.Plastiki chikamu chakakosha chemarara emagetsi nemagetsi zvigadzirwa.Marara epurasitiki anoita 30-50% yemarudzi ese emarara emagetsi nemagetsi zvigadzirwa.Zvichienderana nereshiyo iyi, chiyero chemusika wemapurasitiki emidziyo yemumba ane michina mina chete uye uropi humwe hunogona kusvika pamamiriyoni maviri ematani / gore, uye nekubviswa kwemidziyo yemumba yave nenguva yakafanira, kudzokororwa kwemarara emidziyo yemumba kuchaunzawo hombe. kuwedzera kwemusika.
Mapurasitiki akanyanya marara mumarara emagetsi uye zvigadzirwa zvemagetsi anosanganisira: acrylonitrile butadiene styrene.(ABS),polystyrene (PS), polypropylene (PP), polyvinyl chloride (PVC), polycarbonate(PC), etc. Pakati pavo, ABS uye PS zvinowanzoshandiswa pakugadzira mitsara, mapepa emasuo, mabhomba, nezvimwewo, nehukuru hwekushandisa uye kushandiswa.Musika weramangwana unowedzera uchapa mikana yakawanda yeABS uye PS zvakadzokororwa zvinhu.
