Developer Fabrix employs urban mining to cut carbon footprint in its projects

When old office blocks are demolished, their steel frames are typically smelted down to be recycled, emitting thousands of tonnes of carbon in the process. But at One Broadgate, the steel beams that once framed the London headquarters of inter-dealer broker TP Icap Plc will instead be salvaged from the site and recycled by developer Fabrix. Chief Executive Officer Clive Nichol says the example proves it’s possible to “apply the circular economy to structural elements of buildings.”

Fabrix has purchased 139 tons of steel from the contractor behind the demolition of One Broadgate and plans to use it on other projects in London. The process, known as urban mining, recovers and resells raw materials from waste products.

As reported by Bloomberg Green, engineering consultant AKT II estimates that reused steel could reduce the carbon impact of a building by up to 80%. The U.K. is attempting to encourage this practice, in which construction materials with large carbon footprints would be resold through a marketplace. This move comes at a time of ballooned steel prices in the U.K.

Why don't we re-use what we've already extracted, rather than gouging the planet for ever more raw materials? This thought has spurred a growing band of architects and building firms to look at how to re-use the huge range of materials already hiding within our built environment, from concrete and wood to the metallic bounty within electronic waste

Architecturally-rich cities are both a fount of reusable materials and a way of circumventing the awful cycle of environmental and human destruction caused by mining for the raw substances needed to help mitigate the effects of the built environment on climate change.

Recent projects like the updated version of the Barbican-backed London Centre for Music replacement, which aims to reuse 90% of the site’s existing materials, or the Parisian Montparnasse Tower remodeling currently being undertaken by Bellastock offer the industry high-profile models of how to adapt to the new mandate of climate-sensitive materials usage set forth in Duncan Baker-Brown’s groundbreaking 2017 book The Re-Use Atlas.

"The hardest thing is to change our way of thinking," Bellastock technical director of reuse Mathilde Billet told the BBC. "We need to imagine the city as a material bank, conducive to re-use. There are no ...
