United States EPA Ovomerezeka Detergents.
Sungani masisitomala ali ndi mabotolo ndi mabokosi atsamba ochapira zovala akufuula "Green", "Organic", "Natural". Koma kodi izi ndi zabwino kwambiri kwa chilengedwe?
Mafuta Opangira Mavitamini ndi Zosamalira
Vuto lalikulu kwambiri la zochitika pa chilengedwe pochapa zovala ndi phosphates ndi ena opanga opaleshoni, makamaka nonylphenol ethoxylates kapena NPE. Ma Phosphates analetsedwa kuchokera ku United States omwe ankawatsuka zovala zowatsuka m'zaka za m'ma 1970 kotero kuti sali vuto lalikulu.
Osachita bwino , omwe amathandiza nthaka kuti ayandama pa zovala, kupanga micelle yomwe imayandikana ndi dothi ndikunyamula. Micelle ndi poizoni kuti adye nsomba chifukwa amalowa mu nsomba za nsomba ndipo amachititsa kuti azitha kutulutsa oksijeni m'madzi. Wopanga makina opanga mavitamini ku United States, Proctor ndi Gamble (Mafunde, Gain) anasiya kugwiritsa ntchito opanga mankhwalawa a nonylphenol ethoxylate zaka zingapo zapitazo ndipo phosphates zaletsedwa kuchapa zovala kwa zaka zambiri.
Mavuto ena a chilengedwe ndi mankhwala omwe amachokera ku mafuta ndi mafuta a pulasitiki. Ambiri opanga makina tsopano amagwiritsa ntchito zida zomwe zingagwiritsiridwenso ntchito ndipo nthawi zambiri zimakhala ndi pulasitiki yobwezeretsedwa.
Ngakhale kudziŵa kuti ndi mankhwala otani omwe angapewe kukhala ovuta kungakhale kovuta chifukwa sakhala olembedwa pamatamba. Ngakhale kuti ena opanga mapulogalamu amalembetsa chophimba chilichonse chochapa zovala pamalopo, ambiri samatero chifukwa sichifunikira ndi lamulo.
Komabe, molimbika pang'ono, mukhoza kupita kukawona webusaiti iliyonse ya wopanga kuti muwone mndandanda wa zowonjezera. Ndiko komwe logo yoteteza EPA yotetezeka imakhala yothandiza kwambiri. Mukawona mainawo, mumadziwa kuti mukugula malonda abwino.
EPA imaperekanso mndandandanda wotetezeka wa mankhwala omwe ali pa tsamba lothandizira labwino kuti likuthandizeni kufufuza.
Mukhozanso kusankha detergent popanda mazira onunkhira ndi zonunkhira kuti muchepetse mankhwala omwe amapezeka kwa banja lanu ndi chilengedwe.
Pulogalamu ya EPA yotetezera
Kumayambiriro kwa zaka za 2000, United States Environmental Protection Agency (EPA) inakhazikitsa pulojekiti yotchedwa Design for the Environment kutidziwitsa kuti ndi zinthu ziti zomwe zimagwirizana ndi zomwe akunena. Chimodzi mwa zinthu zomwe zinaphatikizidwa mu pulogalamuyi ndizochapa zovala. Bungweli linapempha opanga makina kuti apereke mndandanda wathunthu wa zosakaniza. Ngati kampaniyo ikanagwiritsira ntchito mankhwala otetezeka kwambiri pamtundu uliwonse, mankhwalawa adalandira mayina apadera. Ngati katunduyo sanali wachifundo, EPA idalimbikitsa kampaniyo kusintha zinthu. Cholinga cha Chilengedwe Chisindikizo chinapatsidwa mwayi wochapa zovala zomwe zinagwirizana ndi zofuna za EPA monga zabwino kwa bizinesi ndi chilengedwe.
Pogwiritsa ntchito mankhwala oposa 2,000 oyenerera pulogalamuyi, malemba ndi malemba a EPA anasinthidwa kukhala pulogalamu yotetezeka. Zamagulu ndi liwu lachisankho labwino limatulutsa mankhwala omwe ali ndi mankhwala othandizira chilengedwe omwe ogula angagwiritse ntchito popanda kupereka nsembe kapena ntchito.
Pulogalamu Yopatsa Chosamala imapereka mndandanda wa zinthu zotetezedwa bwino pa webusaiti yathu ya webusaitiyi kuchokera kwa oyeretsa onse omwe amapereka sopo kuti azichapa zovala, zopangira zovala ndi zopatsa.
Mudzawona kuti zolemba zochepa zowatsuka zovala zowonongedwa. Izi sizikutanthauza kuti ena onse ndi "oyipa". Kugwiritsa ntchito chovomerezeka pakali pano kumadzipereka. Monga opanga opanga maulendo ambiri akukonza malo abwino oyeretsera mankhwala ndi kuyezetsa ntchito, zina zowonjezera zidzatengedwa.
Kuti muwerenge zambiri zokhudza zinthu zowonongeka ndi zachilengedwe komanso momwe mungachepetse mphamvu zanu mu chipinda chochapa zovala, onani ndemanga izi:
