New technology permanently stores CO₂ in recycled concrete

Neustark has realised a system for the permanent storage of CO2 in demolition concrete at the joint venture RECULAR of the Oettinger Group and peterbeton. It can store 10 kilograms of CO2 per tonne of demolition concrete. The plant is the third of its kind from Neustark in Germany.
Neustark and the joint venture RECULAR of the Oettinger Group and peterbeton are joining forces for the permanent storage of CO2 in recycled concrete. RECULAR, based in Baden-Baden, has tested Neustark’s technology for binding CO2 in granulate from demolition concrete in a pilot plant in the Karlsruhe region over the past few months, Neustark announced in a press release. On 26 February, the partners presented the technology and the initial results from the pilot plant at an event.
The pilot project forms the basis for further collaboration between Neustark, the Oettinger Group and peterbeton. “We can store an average of 10 kilograms of CO2 per tonne of demolition material, making it a CO2 sink,” Thomas Karcher, Managing Director of peterbeton, is quoted as saying in the press release. His company is responsible for processing and distributing the CO2-enriched recycled concrete in the project. The Oettinger Group is responsible for procuring and processing the demolition concrete.
“We are delighted to be working with our partners Oettinger and peterbeton to open the first CO2 storage facility of its kind in Karlsruhe and the third in Germany,” explains Valentin Gutknecht, co-founder and co-CEO of Neustark. “This project shows how innovative technologies and local collaboration can shape the future.” There are currently 29 systems with Neustark technology in operation in Europe. Neustark is also involved in the planning or construction of a further 30 plants.
