Reclinker Recycled Cement via Electric Arc Furnaces

Reclinker is a UK cement recycling company whose technology was developed at the University of Cambridge and described in Nature; it is led by CEO Bill Yost. It aims to build a circular economy for cement by turning concrete demolition waste back into clinker, removing the need for virgin raw materials and fossil-fuelled kilns.

Cement paste recovered from construction and demolition waste is fed into the electric arc furnaces that steelmakers already use to recycle scrap, a process the company calls co-recycling. Electrically driven processing converts the recovered paste into recycled clinker that is used to make high-performance, low-carbon cement, while the steel plant continues its normal output. The model is designed to integrate into existing electric arc furnaces worldwide, with production at 7 Steel UK in Cardiff and buyers including cement distributors, concrete producers and contractors.

• Waste-derived feedstock: recovers cement paste from construction and demolition waste.
• Co-recycling in EAFs: converts recovered paste into clinker inside steel recycling electric arc furnaces.
• Electric processing: electrically driven route avoids fossil-fuelled cement kilns.
• Low-carbon cement: recycled clinker used to make high-performance cement with over 50% lower emissions.
• Proven production: thousands of tonnes already made at 7 Steel UK in Cardiff with first commercial sales.
• Replicable model: designed to roll out to electric arc furnace sites in Europe and the US.

Vietnamese steelmakers operating electric arc furnaces can partner to add a recycled clinker line and earn revenue from construction waste. Construction waste recyclers in Hanoi and Ho Chi Minh City can supply recovered cement paste as feedstock. Cement groups can blend recycled clinker into low-carbon cement products.

The company states its process cuts emissions by more than 50% compared with traditional cement while reaching cost parity with conventional cement. Construction waste replaces virgin raw materials, reducing landfill and quarrying. Because it runs in existing electric arc furnaces, the approach avoids building new kilns and lets steelmakers add a cement co-product to their output.

Growing volumes of demolition concrete and the shift of steelmaking to electric arc furnaces create a new link between the steel and cement sectors. Vietnam's steel industry is adding electric arc furnace capacity while cities generate rising construction waste, so co-recycling cement in steel plants fits national circular economy and emissions reduction goals.
