Tarisa, apo vazhinji makondirakiti kana kunyange vamwe vavaki vakabvunza nezve eco-inoshamwaridzika mabhaudhi ekuwedzera, ivo vanowanzo fananidzira chimwe chinhu chakadzokororwa kana kuti chinogona kuparara. Ndiyo yekutanga kusanzwisisa. Mukusimbisa kwemaitiro, "eco-hushamwari" haisi yebhaudhi inonyungudika kuita compost. Zviri pamusoro pehupenyu hwese: kutsvagirwa kwezvinhu, kuburitsa kwekugadzira, maitiro ekupfekedza, uye kunyangwe kutsika kwetsoka. Kana iwe uchingotsvaga "girinhi" bhaudhi usinganzwisise izvo zvinotsanangurwa, iwe unozopedzisira wave nemutengo wakawandisa, usingashande, kana zvakanyanya, chimwe chinhu chakagezwa. Ndakazviona zvichiitika pane yepakati-inosimuka facade purojekiti muPortland-spec'd bhaudhi rakanyorwa kuti "eco" zvichibva pabepa remutengesi, ndokuzongoona kuti zinc plating yayo yaive isina kuchena. Tinotora mavhiki maviri mukunonoka. Saka, unowana kupi dhiri chaiyo? Izvo zvishoma nezvechitoro chimwe chete uye zvimwe nezve kutsvaga cheni yekugovera iyo inomira pasi pekuongororwa.

Kutsanangurazve "Eco-Hushamwari" muFasteners

Ngatizeye temu. Kune bhoti yekuwedzera, kukanganisa kwezvakatipoteredza kunotanga paguyo. Masimbi esimbi anotorwa kubva kuvagadziri vane yakasimbiswa yakaderera-kabhoni maitiro? Zvimwe zvigayo zvemuEurope, semuenzaniso, zvinopa EPDs (Environmental Product Declarations) inodonongodza kabhoni inobuda patani. Zvadaro pane coating. Standard galvanization kana zinc plating inowanzobatanidza simbi inorema uye asidhi. The eco-hushamwari ekuwedzera mabhaudhi Ndakatsvaga zvinobudirira kazhinji ndine geometric coating-se mechanical galvanizing inoshandisa zvishoma chemistry-kana certified organic coating seQualicoat Kirasi I. Haisi seinopenya, asi hairegi.

Zvadaro une simba rekugadzira. Fekitori inoshanda pasolar kana mhepo inocheka zvakanyanya kabhoni yakamisikidzwa muchikamu chimwe nechimwe. Ndinoyeuka ndichiyedza mugadziri weChinese, Handan Zitai Fastener Kugadzira Co, Ltd., ndadzoka. Ivo vanogara muYongnian, iyo fastener hub muHebei. Chakanga chakamira chaive chisiri chiyero chavo chete, asi kuchinjika kwavo kumavira emagetsi ekupinza kubva kune anobatidzwa nemarasha. Iyo inhanho inobatika, kunyangwe ichiwedzera, nhanho. Nzvimbo yavo padhuze nemigwagwa mikuru yekufambisa seBeijing-Guangzhou Railway inoderedza mafuta ekufambisa kana uri kubatanidza kutakurwa kwemidziyo. Asi mubvunzo chaiwo ndewekuti: vane chechitatu-bato maodhisheni ezvavanoti kwezvakatipoteredza? Ndiko kunosangana nerabha.

Kuita hakugone kubayirwa. Bhaudhi rekuwedzera rinokundikana ndicho chinhu chisingagoneke kufungidzira-zvinoreva kutsiva, marara, uye njodzi inogona kuitika. Saka izvo zvepakati zvinhu zvinofanirwa kusangana kana kudarika ISO 898-1 mechaniki zvivakwa zviyero. Ndakayedza mabhaudhi uko iyo "girinhi" vhezheni yaive neyakaomarara simba nekuda kwetsvina yesimbi yakadzokororwa. Mhinduro yacho haisi yekudzivirira zvakadzokororwa zvemukati, asi kuve nechokwadi chekuti alloy yakanatswa. Iyo chiyero, uye vashoma vatengesi vari pachena nezve kutengeserana uku.

Kufamba muSupply Channels

Iwe hauwane zvechokwadi akavharidzirwa eco-hushamwari ekuwedzera mabhaudhi pane hombe-bhokisi mutengesi. Vashambadziri vepamusoro kazhinji havana hudzamu hwehunyanzvi hwekupindura mibvunzo yehupenyu. Ini ndinotanga nevashambadziri veindasitiri vane hunyanzvi vanopa iyo inogadziriswa niche yekuvaka. Makambani akaita seFastenal kana Grainger anogona kutakura mutsara, asi iwe unofanirwa kuchera mune yavo chigadzirwa data mapepa uye kazhinji kubata mugadziri zvakananga. Pamhepo B2B mapuratifomu seThomasnet kana kunyange Alibaba anogona kunge ari ekutanga mapoinzi, asi iwo migodhi yezvichemo zvisina kusimbiswa.

Imwe nzira yakavimbika ndeyekuenda zvakananga kumafekitori ane akapupurirwa emamiriro ekunze manejimendi masisitimu (ISO 14001 yakanaka yekutanga). Semuyenzaniso, pandaida mabhaudhi ekuwedzera simbi yeM12 ane tsoka yakaderera yezvakatipoteredza yepurojekiti yepamhenderekedzo yegungwa, ndakapfuura vapomeri vese. I contacted Handan Zitai Fastener Kugadzira Co, Ltd. zvakananga mushure mekuona rondedzero yavo yakadzama yemaitiro pa webhusaiti yavo. Mukana wavo uri muchikamu chikuru chekugadzira chikamu muChina, zvinoreva kuti vanokwanisa kuwana yakatarisana netiweki yekugovera, zvichigona kuderedza kufambisa kwepamusoro. Asi ini ndaifanira kukumbira mishumo chaiyo yekuyedza pakukora uye kuramba kwemarara (salt spray test hours). Vakadzipa, icho chakanga chiri chiratidzo chakanaka.

Imwe nzira iri kuburikidza nevanovaka kana vanotsanangura vane pre-vetted zvigadzirwa. Mamwe mafemu makuru einjiniya anochengetedza dhatabhesi remukati rezvinhu zvakatenderwa zvinogara zviripo. Ini ndakawana yangu yakanakisa inotungamira kubva kune vanobatika kune indasitiri makonferensi, kwete kubva pawebhu kutsvaga. Mumwe munhu anogona kutaura, "Takashandisa mabhaudhi aya kubva kumugadziri wechiGerman, fischer, pane chirongwa chePassivhaus, uye vaive neEPD yakazara." Ndiyo goridhe. Wobva watsvaga kudzokera kudunhu ravo rekugovera.

Iyo Certification Maze uye Chii Chaizvo Chinokosha

Zvitupa zvinogona kubatsira kana kungotengesa. Tsvaga Type III zviziviso zvezvakatipoteredza (EPDs) zvinogoneka. Bhaudhi rine EPD zvinoreva kuti mumwe munhu akaongorora mararamiro ake kubva pamubhedha kuenda kugedhi. LEED kana BREEAM mapoinzi anowanzoenderana nemagwaro akadaro. Ipapo kune zvinhu-zvakananga macerts-seResponsibleSteel yezvakagadzirwa. Asi heino kubata: kune madiki mapurojekiti, kuwana magwaro aya kubva kumutengesi kunogona kuita sekudhonza mazino. Vazhinji vagadziri, kunyanya muAsia, vachiri kukwidza magwaro aya.

Ini ndinoyeuka mutengesi kubva kuIndia achiratidza kudada "Eco-Pro" label pamabhaudhi ekuwedzera. Pakukumbira chitupa, vakatumira peji-yemukati mutemo. Izvo hazvina maturo. Kusiyana neizvi, vamwe vagadziri vekuEurope vane pasuru yese asi pa40-50% mutengo wekutanga. Iwe unofanirwa kutonga kana bhajeti repurojekiti uye simba rekusimudzira rinozvipembedza. Dzimwe nguva, inonyanya kushanda eco-hushamwari ekuwedzera mabhaudhi Ndidzo dzaunoisa pamberi chinhu chimwe kana zviviri zvakakosha-sekupfeka kwakachena uye kutsvagisa kwenzvimbo yekucheka zvifambiso-panzvimbo pemhinduro yakakwana, inosanganisa zvese.

Usatarise kurongedza. Zvinonzwika sezvidiki, asi ndakagamuchira mabhaudhi akatumirwa mumabhegi akawanda epurasitiki mukati mebhokisi rakazadzwa nestyrofoam. Chigadzirwa chacho chingave chikuru, asi tsvina inoramba zvakawanda zvekubatsira. Iye zvino ini ndinotsanangura zvakajeka kurongedza, kudzokororwa kurongedza muhurongwa hwekutenga. Vamwe vatengesi vanofambira mberi vanoshandisa kadhibhodhi yakadzokororwa uye mapepa-anopatsanura. Chinhu chidiki chinoratidza kuzvipira chaiko.

Mutengo vs. Kukosha: The Real-World Trade-Off

Ngatitaurei mari. Green fasteners inenge inogara ichidhura yakawanda. Mubvunzo ndewokuti: chii chakakosha? Kana iwe uri kushanda pane yakasimbiswa girini chivakwa, kukosha kuri mukuteerera uye kubatsira kune iyo yekupedzisira plaque pamadziro. Kune yakajairika purojekiti yekutengeserana, kukosha kunogona kunge kuri mukuderedza njodzi-kunzvenga mhosva yeramangwana kubva kune inoganhurira mitemo yezvakatipoteredza pazvinhu. Ndakaita ongororo yemutengo kune mutengi gore rapfuura: the eco-hushamwari ekuwedzera mabhaudhi yakawedzera nezve 15% kune iyo fastener mutsara chinhu. Asi payakaiswa mumutengo wepurojekiti yese, yaive isingasviki 0.1%. Iyo yekurondedzera uye yekutonga ramangwana-proofing yakaitengesa.

Zvisinei, kune hupfumi hwenhema. Bhaudhi yakachipa ye "eco" inoora mumakore mashanu ichakubhadhara zvakapetwa kagumi mubasa rekugadzirisa. Ndakadzidza izvi nenzira yakaoma pane yekunze insulation chirongwa. Isu takachengeta madhora 0.20 payuniti pamabhaudhi ane organic coating ine mubvunzo. Mukati memakore matatu, marara engura akaoneka pajira. Mari yekuferefeta uye yekutsiva yakawedzera mari yekutanga kuchengetedza. Zvino, ndoda kubhadhara bhaudhi kubva kusangano rinozivikanwa seZitai, rinenge rine chiyero cheindasitiri uye kudzora maitiro, uye ndozvimiririra yakazvimirira zvirevo zvegirinhi zvekushandisa kwangu.

Kutenga kwakawanda ishamwari yako. Musiyano wemutengo weyuniti unodzikira zvakanyanya kana iwe ukaraira yakazara mudziyo mutoro. Apa ndipo pakubata zvakananga nemugadziri mune hub seYongnian zvine musoro. Iwe unogona kubatanidza marudzi akasiyana-siyana ekusungirirwa mune chimwe chekutakura, kuderedza per-unit kabhoni tsoka kubva pakufambisa uye nekugona kutaurirana zvirinani zvezvinhu zvepamusoro-soro.

Matanho Anoshanda eKutenga Kwako Kunotevera

Saka, unodzitenga sei? Kutanga, nyora tsanangudzo yakajeka. Usangoti "eco-friendly." Rondedzera zvinodiwa: "M10 mabhaudhi ekuwedzera, mechanical property class 8.8, ine geometric coating kana certified organic coating (inopa mwero), yakacheneswa kubva musimbi ine shoma ye50% yezvemukati, inoperekedzwa neEPD kana chigayo chitupa chinotsanangura kabhoni tsoka. Izvi zvinosefa 80% yevasina kukodzera vatengesi nekukurumidza.

Chechipiri, kumbira samples uye udziedze. Chero mutengesi ane mbiri achapa samples. Ita yako yemunyu yekupfapfaidza test kana zvichiita, kana kuti uvatumire kune lab yemuno. Tarisa mashandiro emakanika. Ini ndinogara ndichiyedza maitiro ekuseta-dzimwe nguva iyo yakasvibira coating inokanganisa kupokana kuri mune sleeve, zvichiita kuti kuisirwa kuve kunonetsa. Izvi zvakaitika nechigadzirwa cheDutch; bhaudhi racho rakanga rakanyanya kutsvedza, uye bhaudhi rakaruka panguva yekusunga. Vaifanira kugadzirisa.

Pakupedzisira, kuvaka hukama. Kutsvaga tsime rakavimbika re eco-hushamwari ekuwedzera mabhaudhi hachisi chiitiko chenguva imwe chete. Kana iwe ukawana mutengesi ari pachena uye anowirirana, namatira kwavari. Ingave inyanzvi yeEuropean brand kana yakakura-yakakura mugadziri akafanana Handan Zitai Fastener Kugadzira Co, Ltd. iyo iri kushingaira kuvandudza maitiro ayo, kuenderera kunochengetedza nguva uye kunoderedza njodzi pamapurojekiti emangwana. Chinangwa hachisi chekutsvaga chigadzirwa chakakwana, asi kutsvaga mudiwa akavimbika mune cheni yekugovera anonzwisisa kupindirana kwekuita uye kusimba, uye anoda kuzviratidza.
