Austria-based climate technology company sequestra has opened a laboratory in Vienna for measuring the CO2-binding capacity of industrial mineral residues, including slags, ashes and construction and demolition waste.
The facility uses the company’s proprietary Luma analytics platform to conduct automated carbonation tests and analyse material characteristics. Sequestra said a sample of approximately 3kg can be used to assess a material’s CO2 uptake, potential construction applications and the prospective investment and operating costs of an industrial mineralisation facility.
The laboratory will serve customers in industries including cement, steel, waste incineration, biomass combustion and construction.
Meanwhile, sequestra is developing a pre-industrial grinding and carbonation line at its Attnang-Puchheim technology centre. The company aims to bring its first industrial-scale CO2 mineralisation plants to market from late 2027.
Sequestra, which raised EUR3m (US$3.5m) in seed funding earlier in 2026, employs 18 people across three locations.
