Tawm tsam keeb kwm yav dhau los ntawm lub ntiaj teb ib puag ncig tiv thaiv nthwv dej, lubgravel thiab crushed pob zebkev lag luam yog accelerating nws txoj kev hloov ntsuab. Qhov kev hloov pauv no, coj los ntawm cov cai, txhawb nqa los ntawm cov thev naus laus zis, thiab tau tsav los ntawm kev lag luam, yog thawb kev lag luam los ntawm kev siv siab -kev siv, siab - qauv emission mus rau tus qauv kev loj hlob.
Txoj cai tsav yog lub hauv paus tseem ceeb ntawm kev hloov pauv. Lub EU's "Nature Restoration Law" kom meej meej hais tias ecological restoration tus nqi ntawm mines yuav tsum ncav cuag 100%, yuam cov tuam txhab lag luam los koom nrog ecological restoration rau tag nrho cov mining voj voog. Ib lub pob zeb pob zeb hauv lub tebchaws Yelemes tau tsim kho tshiab "tsim tsuas yog thaum rov kho dua" qauv, ua tiav cov nroj tsuag rov tsim kho synchronously rau txhua 10,000 square metres mined, thiab biodiversity ntawm thaj chaw mining rov qab mus rau qib ua ntej - mining tom qab 3 xyoos. Tuam Tshoj tau teem lub hom phiaj ntawm 50% ntsuab mines los ntawm 2025. Los ntawm kev sib xyaw ua ke ntawm cov cai xws li kev txo se thiab kev them nyiaj yug, nws tau txhawb ntau dua 2,000 mines kom ua tiav cov kev hloov pauv ntse, nrog cov plua plav emissions txo los ntawm 70% piv nrog cov txheej txheem ib txwm muaj. Indonesia tau txais ob txoj hauv kev: ntawm ib sab, nws tau tshawb xyuas thiab cuam tshuam nrog ntau dua 3,000 qhov chaw khawb av tsis raug cai; Ntawm qhov tod tes, nws tau tsim kom muaj kev pov thawj ntsuab ntsuab, ua kom cov peev txheej siv cov xuab zeb raug cai rau 85%.
Recycled aggregates tau dhau los ua ib feem tseem ceeb ntawm kev lag luam ncig. Cov ntaub ntawv qhia tau hais tias lub ntiaj teb no recycled aggregates lag luam yuav ncav cuag $ 56.2 nphom los ntawm 2025. Tuam Tshoj txoj kev tsim kho cov khoom siv pov tseg tau nce mus rau 25%, txo cov xuab zeb thiab pob zeb mining los ntawm ntau tshaj 100 lab tons hauv ib xyoos. Kev tsim kho cov khoom siv pov tseg hauv Beijing hloov cov pob zeb ua vaj tse rau hauv C30- qib rov ua dua cov khoom sib xyaw los ntawm kev sib xyaw "crushing-sib nqus sib cais-kev tshuaj ntsuam" thev naus laus zis, uas yog siv rau kev tsim kho hauv nroog, txuag 400,000 yuan hauv pob zeb nqi ib mais. Kev tsim kho tshiab ntawm Britain's Brewster Cov Kwv Tij yog qhov ua piv txwv ntau dua. Nws cov khoom siv rov ua dua tshiab tsis yog tsuas yog txo cov pa roj carbon hneev taw los ntawm 40% tab sis kuj tseem nkag mus rau EU pej xeem cov ntawv yuav khoom los ntawm EPD daim ntawv pov thawj, dhau los ua cov khoom siv rau kev tsim kho ntawm London Olympic venues.
Tsawg- cov kev coj ua carbon yog hloov kho txoj kev lag luam txoj hauv kev. Ib txoj haujlwm tsim kho vaj tse hauv Saudi Arabia tau txais kev siv thev naus laus zis ua ke ntawm cov pob zeb pob zeb thiab dynamic compaction, hloov cov tsoos pob zeb cushion los ntawm gravel compaction foundation. Ib qhov project txo qis carbon emissions los ntawm 63% thiab txuag 12,000 tons ntawm cement. Qhov kev tawg ntawm cov neeg Ixayees lub Brenmiller Zog yog qhov ntau dua subversive. Nws tsim gravel zog cia system siv lub hnub ci zog kom sov gravel rau 600℃rau lub zog cia. Tom qab hloov cov roj- raug rho tawm haujlwm boilers hauv ib qho chaw ua lag luam hauv Tel Aviv, nws txo cov pa roj carbon emissions los ntawm 8,000 tons ib xyoos twg nrog lub zog khaws cia ntawm ntau dua 70%.
Los ntawm txoj cai yuam kev mus rau kev ua lag luam nco ntsoov, kev hloov pauv ntsuab ntawm kev lag luam pob zeb thiab pob zeb crushed tau txav los ntawm ib qho - taw tes rau kev hloov pauv mus rau qhov kev hloov pauv. Nrog rau kev loj hlob ntawm cov thev naus laus zis rov ua dua tshiab thiab nrov ntawm cov txheej txheem qis - cov pa roj carbon monoxide, qhov kev lag luam ntawm cov khoom siv qub qub tau rov ua dua tshiab, muab kev txhawb nqa ruaj khov rau kev txhim kho thoob ntiaj teb kev tsim kho vaj tse.
