Zaj Dab Neeg Txog Hom Lag Luam | UrbanMines: Los Ntawm Cov Chaw Ua Mines Hauv nroog Mus Rau Cov Khoom Siv Yav Tom Ntej
Lub tswv yim ntawm UrbanMines yog los ntawm lub hauv paus ntawm "urban mining" uas tau qhia tawm xyoo 1988 los ntawm Xibfwb Michio Nanjo ntawm Lub Tsev Kawm Ntawv Institute of Mineral Processing and Metallurgy ntawm Tohoku University, Nyiv Pooj. Xibfwb Nanjo tau hais tias kev khaws cov khoom lag luam pov tseg hauv nroog yog ib qho chaw khaws cov khoom siv rov ua dua tshiab, uas nws hu ua "urban mining." Lub tswv yim no qhia txog kev tswj hwm cov peev txheej kom ruaj khov, hais txog kev rov qab tau cov khoom siv hlau tseem ceeb los ntawm cov khib nyiab hluav taws xob thiab txhawb nqa kev ruaj khov ntawm ib puag ncig thiab kev lag luam mus sij hawm ntev.
Ib qho piv txwv zoo yog lub rooj tsavxwm luam tawm (PCB) uas pom muaj nyob rau hauv cov khoom siv hluav taws xob - feem ntau hu ua "urban mines" - uas muaj ntau yam hlau tsis tshua muaj thiab cov khoom siv av tsis tshua muaj. Nws sawv cev rau tus qauv sawv cev ntawm lub tswv yim "urban mines".
Txij li thaum pib ntawm lub xyoo pua 21st, Tuam Tshoj txoj kev hloov pauv thiab txoj cai qhib kev lag luam tau tsav kev nthuav dav ntawm kev lag luam sai, kev siv dav dav ntawm cov khoom siv hluav taws xob rau cov neeg siv khoom (3C cov khoom), thiab kev tshwm sim ntawm kev lag luam xws li cov laug cam luam tawm (PCBs), IC lead frames, thiab cov khoom siv hluav taws xob precision. Qhov kev loj hlob no kuj tau ua rau muaj kev nce ntxiv ntawm cov khib nyiab hluav taws xob thiab cov khoom siv tooj liab seem. Ua teb rau qhov kev hloov pauv no, UrbanMines tau tsim tsa hauv Hong Kong xyoo 2007, thawj zaug tsom mus rau kev rov ua dua tshiab ntawm PCBs thiab cov khoom siv tooj liab seem, yog li ntawd tso lub hauv paus rau nws cov haujlwm rov ua dua tshiab.
Los ntawm kev nce qib tas mus li hauv thev naus laus zis, kev sib koom ua ke ntawm cov khoom xa tuaj, thiab kev nthuav dav ntawm kev ua lag luam, UrbanMines tau hloov pauv los ntawm kev ua lag luam rov ua dua cov khoom siv mus rau hauv lub tuam txhab uas tsav los ntawm thev naus laus zis uas koom ua ke kev tshawb fawb thiab kev txhim kho cov khoom siv siab heev, kev tsim khoom, thiab kev rov ua dua tshiab. Lub npe thiab hom "UrbanMines" tsis yog tsuas yog qhia txog lub tuam txhab keeb kwm hauv kev rov qab tau cov peev txheej hauv nroog xwb tab sis kuj yog lub cim ntawm nws txoj kev cog lus tas mus li los txuas kev tsim kho tshiab ntawm cov khoom siv siab heev nrog kev siv cov peev txheej ruaj khov.
Peb ua raws li lub hauv paus ntsiab lus hais tias "Kev siv tsis muaj kev txwv, tab sis cov peev txheej muaj tsawg; Siv kev rho tawm los xam cov peev txheej, siv kev faib los xam kev siv." Vim muaj teeb meem thoob ntiaj teb xws li kev tsis txaus peev txheej thiab kev hloov pauv zog, UrbanMines tau tsim lub zeem muag zoo - "Lub Zeem Muag Yav Tom Ntej" - uas sib txuas kev nce qib thev naus laus zis nrog kev ruaj khov. Lub tswv yim no tsom mus rau cov khoom siv hlau tsis tshua muaj siab, cov khoom siv av tsis tshua muaj zog, thiab cov txheej txheem rov ua dua tshiab ntsuab, kaw-lub voj voog. Siv cov thev naus laus zis tshuaj lom neeg tshiab, peb mob siab rau kev xa cov kev daws teeb meem khoom siv tiam tom ntej rau kev lag luam thev naus laus zis siab.
Saib mus tom ntej, UrbanMines lub hom phiaj yog los ua tus thawj coj thoob ntiaj teb hauv kev siv cov ntaub ntawv ua tau zoo thiab kev siv cov khoom siv rov ua dua tshiab, hloov nws txoj kev txawj ntse hauv kev ruaj khov mus rau hauv kev sib tw kom zoo dua hauv kev lag luam thoob ntiaj teb.
