The process

Reduction at the source, not at the stack.

The Acriva process does not burn fuel and does not run a kiln. Cement sets at ambient temperature from activated industrial residues. The CO₂ is not made in the first place, so there is far less to capture, store or pay for.

The carbon intensity we target per ton is being confirmed through independent production measurements and a life cycle assessment with an Environmental Product Declaration (LCA/EPD). We publish a figure only once it is independently verified.

No combustion

The process runs without kilns, fossil fuels or thermal energy. That removes the industry's largest cost driver and its largest emission source from the production step.

Secondary raw materials

Slag, fly ash, quarry fines, mine tailings and other industrial residues are activated and become the cement's raw material. A disposal cost for one industry becomes a feedstock for another.

CO₂ uptake during curing

The cement takes up CO₂ from the air as it cures through carbonation. We measure the uptake per plant and document it in the certificate. We state the figure only once the test data is on file.

Capture at the stack (CCS) Baseline

  • 150 to 300 EUR per ton of CO₂ captured
  • Retrofit investment in the billions across a plant portfolio
  • Chemical scrubbing of diluted flue gas, typically 15 to 30% CO₂
  • Dependent on scarce geological storage and third-party pipelines
  • Ongoing operating cost for every ton emitted

Reduction at the source (Acriva) Acriva

  • Significant CO₂ reduction targeted at plant level, independently measured and verified per ton
  • Compatible with existing plant infrastructure. No full rebuild required.
  • Ambient-temperature process, no kilns and no combustion energy
  • Uses existing plants and local raw materials. No new cement plant to build.
  • Measured CO₂ uptake during curing, reported where test data exists

Acriva complements CCS rather than replacing it: less CO₂ produced means less to capture, which lowers cost across the whole chain.

ESG performance

Measurable results across all three ESG dimensions.

Lenders, rating agencies and public buyers ask for evidence. The process delivers it as plant-level numbers rather than statements of intent.
