More and more recyclers are relying on the innovative CO₂ storage technology from neustark to produce sustainable building materials. By carbonating concrete granulate, CO₂ is permanently bound in the concrete, improving the environmental footprint.
Numerous companies are already using this technology to establish carbonated recycled concrete on the market successfully. The following examples show how these companies market their products and what advantages these environmentally friendly building materials offer.

Möckli Beton AG, Switzerland
NovoCon is an innovative recycled concrete that stores CO₂ through carbon capture and storage in the concrete granulate.
Advertising proposition...
Sustainability through CO₂ storage, improved concrete quality and high recycling rate. The conservation of primary resources and the reduction of greenhouse gas emissions are particularly emphasized. The Möckli Beton AG also mentions that the concrete can be transported over 90 kilometers (instead of 25 as with regular RC concrete) before it no longer makes ecological sense.
Properties
- Storage of 10 kg of CO₂/m³ of concrete.
- Recycling rate of over 99 %.
- Optimized fresh and hardened concrete properties.

Risi AG, Switzerland
Jura Cyclo Carbo is a sustainable structural concrete made with carbonated concrete
granulate, which stores up to 10 kg of CO₂ per cubic meter. The carbon footprint
improves by 5 % compared to concrete with untreated concrete granulate.
Advertising proposition...
Sustainability through CO₂ storage and compliance with strict environmental standards, such as MINERGIE-ECO® regulations. The regional origin of the raw materials and the improvement of the carbon footprint are particularly emphasized.
Properties
- Storage of 10 kg of CO₂/m³ of concrete.
- Meets MINERGIE-ECO® regulations.
- Recycled content: contains regional concrete granulate from demolition material.
- Produced with 100 % Swiss raw materials.
Risi's sustainable structural concrete is developed using neustark technology.
Vigier Beton AG, Switzerland
ECOTOP and ECOGOLD are CO₂-reduced recycled concretes with high environmental friendliness. In addition to the CO₂-enriched RC concrete, ECOGOLD also uses sustainable cement. They combine a high proportion of recycled material with additional CO₂ storage to further improve the carbon footprint.
Advertising proposition...
Sustainability, CO₂ savings and the use of recycled materials. Vigier Beton emphasizes the CO₂ binding and the high recycling rate of the concretes.
Properties
- ECOTOP: CO₂ savings of 30-35 %.
- ECOGOLD: CO₂ savings of 35-45 %, cement with less than 100 kg CO₂ permetric ton.
Vigier and Alluvia have jointly invested in a neustark plant for durable carbon removal.
Alluvia AG, Switzerland
Green in grey is a CO₂-reduced concrete made with recarbonated mixed and concrete granules. It contains up to 75 % recycled content and also binds CO₂. The concrete of Alluvia AG is further used for environmentally friendly construction
projects or recycled concrete for building construction.
Advertising proposition...
High recycled content and minimal CO₂ footprint, concrete for sustainable construction projects and the circular economy.
Properties
- Up to 75 % recycled granulate.
- CO₂ storage through recarbonation of the granulate.
- Reduced CO₂ footprint.
The CO₂ storage facility from Alluvia and Vigier has an annual storage capacity of 1,000 tons.
Conclusion
In summary, the aforementioned companies show how neustark's CO₂ storage technology is successfully used in concrete production. These sustainable products promote the circular economy and contribute to reaching our climate goals.
The improved properties of carbonated concretes increase confidence in these solutions and allow recyclers to offer environmentally friendly options that are both technically and economically viable.
Given the increasing demand for sustainable building materials, now is the ideal time for recyclers to invest in these technologies and offer their customers eco-friendly options.
