We remove CO₂ from the atmosphere – and store it permanently

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 hundreds of thousands of tonnes of CO₂ in this decade, and beyond that.

By removing CO₂ from the atmosphere and storing it in demolition concrete permanently, neustark's technology generates negative emissions.

Reducing the emissions we produce across the globe is crucial – but to reach our climate goals, carbon removal is also indispensable.

For a bright future of all generations on our planet.

Neustark captures, transports and stores CO₂ by working with source (e.g. biogas plants) and storage (i.e. concrete recyclers) partners located in close proximity to each other.

Our mineralization technology binds the CO₂ in demolished concrete, thus removing it permanently.

Businesses at the forefront of climate action buy our CDR, which, alongside their reduction efforts, helps them to achieve net-zero.

It’s a win-win-win for our partners and clients, and ultimately and most importantly, the planet and all generations.
