Industrial partners

Industrial residues become raw material.

The Acriva process is built on secondary raw materials. Plants that produce them gain an outlet with value instead of a disposal cost, and cement producers gain a local feedstock. We work with both sides.

The glassy by-product of iron making, one of the most established secondary cement materials.

Coal-fired power plantsFly ash

Fine ash captured from flue gas, often stockpiled or landfilled where it is not already sold.

Biomass power plantsBiomass ash

Ash from wood and agricultural residue firing, a growing stream as biomass replaces coal.

Quarries and minesFines and tailings

Fine fractions from crushing and the tailings left after ore processing, usually held in storage facilities.

Brick plantsClay residues

Off-specification clay and fired material that would otherwise be discarded.

Concrete plantsReturned fines

Fines recovered from returned and washed-out concrete at ready-mix plants.

Glass industrySand residues

Fine sand and residues from glass production and recycling.

Cement producersExisting lines, licensed process

Licensees that turn qualified residue streams into low-carbon cement on the lines they already run.

Why it works for both sides

One residue stream, two businesses that gain.

A residue that costs one plant money to store or dispose of can be a qualified raw material for a cement plant nearby. The value comes from making that connection and documenting it.

For residue suppliers

An outlet with value for material that is otherwise stockpiled, landfilled or sold below its worth. Less material held on site, and a documented use for it that stands up in ESG and permitting reviews.

For cement producers

A local feedstock for the licensed process, qualified before production starts. Shorter supply routes and less dependence on the energy-intensive clinker step.

For buyers and regulators

The origin of each residue stream is recorded in the chain of custody behind every documented ton, so the material story can be checked, not just stated.

How a partnership works

From a residue sample to a supply route

We qualify the material first and only then look for a producer to use it. Nothing is committed before the test results are shared with you.

  1. 01

    Residue profile

    You tell us the type of residue, volumes per year, location, how it is stored today and any test data you already hold.

  2. 02

    Material qualification

    We test samples for use in the Acriva process and share the results with you, including what the material is suited for and what is not.

  3. 03

    Matching

    Qualified streams are matched with licensed or prospective producers within a practical transport distance.

  4. 04

    Supply and documentation

    Volumes, quality specification and logistics are agreed for supply to the producer. The origin of the material is recorded in the production documentation.

What we look for

The questions a residue stream has to answer

  • Type and chemistry. What the material is and how it was produced, with any analyses already on file.
  • Volume and consistency. How much is available each year, and how steady its composition is from batch to batch.
  • Location. Where it is stored and how far it is from cement plants that could use it.
  • Current handling. Whether it is stockpiled, landfilled, sold or under a disposal contract today.
  • Permits and records. The environmental permits and records that cover the material and its handling.
