Founded in 2021, with offices in Copenhagen and Berlin, Again is a startup that has developed a biomanufacturing process that combines ancient bacteria with cutting-edge biotechnology. The company ferments CO₂ and hydrogen to create emission-free chemicals through a single-phase carbon capture process to reduce emissions and decarbonise the petrochemical sector.
The Danish startup, winner of the nova-Institute’s Renewable Material of the Year prize, collects CO₂ waste and ferments it with hydrogen, in a process akin to beer brewing, and creates valuable chemicals for products and materials.
Born from a decade-long combined research effort by the Danish Technical University, Stanford, and MIT, this technology is already in operation in the first plant built in Denmark, which converts CO₂ into acetate, a chemical used in adhesives, solvents, plastics, textiles, and cosmetics, reducing emissions by up to 80%. Again builds its plants in collaboration with emission-generating industrial partners and sources CO₂ directly on-site, reducing transportation to a minimum. Again’s first plant is integrated with a source of CO₂ originating from an industrial wastewater treatment plant.
“We must do everything possible to prevent the climate crisis and this means rethinking the way we create everyday objects to decarbonise the production process,” Again co-founder Max Kufner told Renewable Matter. “With Again, we are helping global businesses to reduce their emissions through recycling and improving supply chain resilience.”
