neustark removes CO2 from the atmosphere
permanently stores it in recycled concrete
and cuts new emissions by reducing the use of cement.
What if the concrete we build with could help solve the global climate crisis?
By removing CO2 from the atmosphere and storing it in 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 (CDR) is indispensable.
In 2020, we pioneered the market with our modular plants enabling producers to capture CO2 in recycled concrete. In 2021, we rolled out our first stationary site, and in 2022, had four sites up-and-running in Switzerland - and storing CO2 successfully.
We are on a mission to store one million tons of CO₂ in 2030, and are currently scaling up across Europe. We work with biogas plants to source our CO2, concrete recyclers to store the CO2, and companies with ambitious net-zero strategies to acquire our CDR.
CO2 is removed from our air, carbon dioxide levels in our atmoshpere are thereby reduced.
That's how we undo damage from the past in order to save our future.
About 10kg of the captured CO₂ are permanently stored in each cubic meter of concrete.
It's a natural process sped up from centuries to hours by our technology
(we also quadruple the CO₂ uptake)
The enriched material allows for the reduction of cement in fresh concrete.
Up to 20kg of new CO2 emissions per m³ of fresh concrete are avoided.
About 10kg of CO2 are irreversably stored per m³ of concrete.
Up to 20kg of new CO2 emissions are avoided in the production process.

At neustark, we enable permanent CO2 storage...
...for a bright future of all generations on our planet.
How do we do that?
Through an intricate process of sourcing, transporting and ultimately storing CO2 in recycled concrete, permanently.

neustark's management team
We are now significantly scaling up our operations. We've shown that our technology and process are ecologically and commercially viable by having pioneered the first and, in 2022, rolled out four sites permanently storing CO₂.
To maximize our impact, we are now expanding in Switzerland and across Europe on the road to storing one million tons of CO₂ in 2030.
Each month, we are entering and rolling out partnerships with local CO₂ sources as well as local concrete recyclers to install our technology and process onto their existing sites - without disrupting their current processes, helping them to become more sustainable and commercially innovative and successful.
At the same time, we are increasingly examining and closing deals with larger companies that have ambitious net-zero strategies - and that see the benefit and need of investing in negative emission technologies. These organizations purchase our CDR, and we help them reach their sustainability goals.
What's more, we're researching other technologies to permanently store CO₂. Amongst others, by playing a leading role in the ETH-led research project DemoUpCARMA, which is piloting the geological storage of Swiss biogenic CO₂ in Iceland.
There's so much more to come! Join neustark on our journey of enabling permanent CO₂ storage - for a bright future of all generations on our planet.
