From incinerator bottom ash to certified CO2 savings

By recovering metals and minerals from incineration slag, the mining of primary raw materials is avoided. Primary extraction is extremely CO2-intensive, so every tonne of secondary raw material we produce directly reduces emissions at the source.

Most CO2 claims are based on future promises, forests or nature. Ours are grounded in existing industrial infrastructure: IBA processed today, metals recovered today, emissions avoided today. Physical, measurable, irreversible.

High voltage pulses selectively fragment incineration slag under water. Metals remain intact and can be recovered by type. The process achieves a recovery rate of 50%, three times more than conventional methods.

Centro Uno is located in Full-Reuenthal (Aargau) and has been operational since 2023. Centro Due in Kerzers (Fribourg) is under construction and will be commissioned in 2026. Additional sites are in the planning stage with a target of 5 to 6 facilities across Switzerland.

For companies with sustainability targets looking to offset their unavoidable emissions with high-quality, transparent credits, especially those who value Swiss origin and physical verifiability.

Permanence risk refers to the possibility that CO2 avoidance is reversed later. This is common with nature-based approaches: forests can burn, be logged, or suffer disease. Our industrial process has no such risk — once metals are recovered, emissions from primary production are permanently avoided.
