Demolished concrete is the world’s largest waste stream. Neustark turns this waste stream into a carbon sink. We’ve created and deployed a solution that mineralizes CO₂ in demolished concrete aggregate – thus permanently storing it and removing the CO₂ from the atmosphere.
We work with biogas plants to source our CO₂, concrete recyclers to store the CO₂, and companies with ambitious climate strategies that acquire our CDR (carbon dioxide removal).
In a nutshell: we permanently remove CO₂ and thus generate negative emissions. We are currently scaling up across the globe – on our way to removing one million tons of CO₂ in 2030, and beyond that.
