Block - Lite is a diminished concrete manufacturer in an industrial corridor of Flagstaff , Arizona . The third - contemporaries family line make water brick and other masonry materials for retaining wall , driveways , and landscaping projection . The company was already a local drawing card in sustainability — in 2020 , it became the first manufacturing business in Flagstaff to power its cognitive operation with on - site solar gore . But now it ’s doing something much more challenging .
On Tuesday , Block - Lite herald a pioneering collaborationism with climate tech startups Aircapture and CarbonBuilt to go down on carbon dioxide from the atmosphere and hoard it in concrete stoppage . The companies guess the projection will reduce the carbon footprint of Block - Lite ’s product by 70 percent , creating a model they hope could reshape the industry .
Concrete creates an tremendous problem for the climate . It ’s one of the literal building blocks of club , and it has beengrowing more carbon intensiveeach year . Most of that carbon does n’t come from manufacture concrete , but from the production of its master ingredient , cementum . Cement yield is creditworthy for some10 per centum of industrial carbon emissionsin the U.S.

CarbonBuilt has develop a solution that addresses the issue in two discrete mode . First , the party found a proprietary way to replace cement with a intermixture of inexpensive , locally - sourced industrial waste materials . CEO Rahul Shendure told Grist they include plebeian byproducts of coal plant , steelmaking , and chemical product that would , for the most part , otherwise be fate for landfills . The company ’s second feat is the way its equipment hardens that slurry into concrete pulley-block — by curing it with carbon dioxide . That ’s where Aircapture comes in . The company will establish one of its automobile which distil carbon paper dioxide from the ambient air directly on Block - Lite ’s site .
“ Our technology is pretty whippy in where we source CO2 from , ” say Shendure . “ The thing that ’s dissimilar about this project in particular is that we ’re sourcing the atomic number 6 dioxide from direct melodic phrase capture technology . ”
It ’s an idea that a handful of other companies are pursue . In February , a similar partnership between another direct air gaining control companionship called Heirloom and concrete startup CarbonCuredemonstrated its process for the first time . This also is n’t CarbonBuilt ’s first projection — the company is retrofitting aconcrete plant in Alabama forebode Blair Block . In that case , the CO2 will do from burn down biomass in a boiler .
The Flagstaff project is break ground , in part , thanks to a $ 150,000 grant from theFour Corners Carbon Coalition , a group of local government throughout the Southwest that syndicate resources to finance task that remove carbon copy dioxide from the air . The coalescence was born of the realization that communities with ambitious finish to become carbon inert will likely need to endue in such solutions , many of which are still embryotic .
“ If one local government strain to do this on their own , it ’s gon na be extremely high-priced and clock time intensive , and we do n’t have the technical expertise , ” Susie Strife , the sustainability director for Boulder County , Colorado , a founding extremity of the coalition , said in an interview with Grist last year . “ We ’re judge to combine imagination and create a sort of a local government weapons platform for carbon copy dioxide removal . ”

In addition to that financing , Shendure said the troupe plans to sell carbon copy credits for the CO2 that Aircapture ’s equipment draw out of the aura , as well as for the carbon reductions from using less cementum . “ We ’ve got a varsity letter of purpose from a buyer and that ’s going to be critical to this project , ” he said . “ There ’s a lot of company right now that are pay insurance premium credit price for emerging technologies so that we get more of these out there in the real creation . ”
Block - Lite did not respond to Grist ’s inquiry , but in apress vent , the party evoke that the new concrete products would be no dear than its current offerings . “ All too often sustainable edifice materials involve a trade off between cost and carrying out , but what is unparalleled about this undertaking is that there ’s no ‘ green premium . ’ ” Block - Lite say . “ We ’re conk out to be able to grow on - spec , ultra - crushed carbon paper block at price parity with traditional block which should speed adoption and shock . ”
