Neustark utilizes mineralization technology to convert CO₂ emissions from biogas plants into stable minerals within recycled concrete, permanently storing carbon and generating negative emissions. This process addresses the significant challenge of CO₂ accumulation in the atmosphere by transforming demolished concrete, the world's largest waste stream, into a carbon sink.

Problem
Accumulation of CO₂ in the atmosphere is a significant environmental challenge. Demolished concrete, the world's largest waste stream, presents an opportunity for carbon sequestration but lacks effective methods for permanent CO₂ storage.
Solution
Neustark provides a mineralization technology that transforms demolished concrete into a carbon sink. The technology captures CO₂ emissions from sources like biogas plants and permanently stores them within recycled concrete aggregates. This mineralization process converts the captured CO₂ into stable minerals, effectively removing it from the atmosphere and generating negative emissions. Neustark partners with concrete recyclers to embed its technology at their sites, valorizing CO₂ emission volumes and enabling businesses to achieve their net-zero climate strategies through verified carbon dioxide removal (CDR).
Target Audience
Neustark targets construction and demolition waste recyclers, CO₂ sources such as biogas plants, and businesses with climate targets seeking verified carbon removal.
Features
- Mineralization technology that binds CO₂ in demolished concrete, permanently storing it as stable minerals
- CO₂ capture and liquefaction process for efficient transport to concrete recycling plants
- Integration with existing concrete recycling processes, allowing recyclers to produce CO₂-enriched granules for use in recycled concrete or road construction materials
- Partnerships with biogas plants to source CO₂ and concrete recyclers for CO₂ storage
