Nyika yedu nemakungwa edu akazara nepurasitiki, saka kushandiswa kwepurasitiki kunokosha kupfuura kare. Heano mamwe mazano echokwadi pamusoro pekugadziridza mapurasitiki, uye kuti ungaderedza sei zvakakonzerwa nemapurastiki kumhepo.
Nei Tichidzokorora Plastics?
Maererano nezvimwe zvinofungidzira, mapurasitiki anoumba anenge 10 muzana emarara munzvimbo yeUnited States. Zvizhinji zvepurasitiki zvinoshandiswa kushandisa gasi chaiyo kana chimwe chimwe chechipiri chemicrochemical.
Apo mamwe mapurasitiki anoshandiswa, zvimwe zvinodhaka zvepetroleum zvinodiwa - uye zvinokonzerwa nemasikirwo emakemikari epetrochemical zvakanyatsorongedzerwa.
Mabhodhoro epurasitiki, somuenzaniso, akaongororwa sezvinoita vanhu vakawanda vachivashandisa kunwa mvura yakabhoderedzwa. Muna 1976, muvhareji weAmerica wakanwa 1.6 galoni emvura yakabhoderedzwa gore. Asi nhamba iyoyo yakakwira kusvika ku 28.3 mabhiriyoni gore mugore ra2008. Muna 2015, izvo zvakasimuka kusvika 36.3 galoni pamunhu. Uye chete 25% yeavo mabhodhoro epurasitiki anodzorerwa zvakare - asi kudzokorora imwe tani yepurasitiki inoponesa inofungidzirwa makiromita makumi maviri emadhora edzimba.
Purogiramu Inoshandiswa Purasitiki
Chii chinonzi kuverengwa kwezvinhu zvinoshandiswa patsva pazvinhu zvepurasitiki zvinorevei? Vanotsanangura rudzi rwepurasitiki kuti chinhu chacho chakaitwa, uye kuti chinogona kushandiswazve sei. Somuenzaniso, chiratidzo chekudzokorora uye nhamba 2 ndicho chiratidzo cheH HDPE, kana kuti yakakwirira-polyethylene. HDPE ipurasitiki yakaoma, yakasimba inoshandiswa nyore nyore muzvinhu zvakadai semapuranga epurasitiki.
Kune huwandu huwandu hunomwe hunoendeswa kumapurasitiki anoona rudzi rweplastiki resin inoshandiswa mumashoko acho. Iyi nhamba inonzi inonzi resin code code, inoshandiswa kugadzira mapurasitiki munguva yekudzokorora.
Kudzokorora Mapurasitiki neArtcycling Plastics
Apo plastiki inodzokodzwazve, inowanzo "yakaderedzwa," kureva, iyo inoshandiswa kuita imwe yepamusoro yemhando yepurasitiki.
Mabhodhoro emvura yeplastiki, somuenzaniso, haagoni kudzokodzwa zvakare mumabhodhoro matsva epurasitiki. Pane kudaro, mashizha kubva mumabhodhoro epurasitiki anoshandiswa kugadzira michina yepisiti uye kuvharidzira kuzadza kwejaketi dzechando.
Michina yakawanda inogadzirwa kubva kumapurastiki akashandiswa zvakare anosanganisira matoyi, zvipfeko zvemotokari, zvinyorwa kana mapuranga epurasitiki, mabheti emvura, mabhii ekupfeka, mabwendefa, mabhenji epaki, motokari bumpers, magwatiro emigwagwa, mabhazi emabhedha emabhedha nemigodhi yemarara. Uye dzakawanda idzi hazvikwanisi kudzokodzwazve, zvichiita mapurasitiki "tsvina yekupedzisira" tsvina.
Zvinetso Nekushandisa Zvishandiso Plastics
Haasi munhu wose ane shungu pamusoro pekugadziridza mapurasitiki. Pane kukakavadzana pamusoro pezvakasvibirira zve "plastiki" zvepurasitiki, izvo zvinodikanwa nehuwandu hwebasa nemasimba (kazhinji kubva pane zvicherwa). Mushumo unobva kuEcology Center muBerkeley, Calif., Inotaura kuti kushandiswa kwepurasitiki yakashandiswa kunodhura kupfuura kungoshandisa mhandara yemapurasitiki emvura, iyo inoderedza mushamba wemaplastiki akadzokidzwa zvakare.
Izvochete Ecology Centre rapurisa inotsanangura kuti nzira yakanakisisa yekugadzirisa zvinokonzerwa nemaplastiki kune zvakatipoteredza hazvisi kuburikidza nekudzokororazve, asi nekutanga kuderedza kushandiswa kwemaplastiki zvakakwana. Vanokurudzira kushandisa girazi rekugadziriswa kana pepa rekugadzirisa uye kushandisazve mapuranga epurasitiki - bhodhoro replastiki, vanocherechedza, rinogona kugadziriswa uye kushandiswa zvakare kakawanda.
