Turning Incineration Ash into High-Value Construction Materials and Water Filters

environmentPilotedTRL 6

Imagine the gray ash left over after burning trash or sewage. Instead of paying to bury it in a hole in the ground, this project treats it like a gold mine. It pulls out rare metals and nutrients, then turns the remaining minerals into bricks or water filters. It's basically turning a costly waste problem into a source of raw materials.

The business problem

What needed solving

Companies pay high fees to landfill 25 million tons of incineration ash annually while losing valuable metals and minerals. There is also a lack of market trust and clear regulations for using this ash in new products.

The solution

What was built

A software tool for ash producers to assess waste value and an optimization model for supply chain logistics. They also developed real-scale pilots for recovering metals and creating construction/water-treatment materials.

Who can put this to work

Construction
enterprise
Target: Concrete and cement manufacturer

If you are a concrete manufacturer dealing with high raw material costs — this project developed a way to use aluminosilicate-rich minerals from ash as a feedstock. This allows you to replace expensive virgin materials with secondary resources. It helps you create more sustainable building products.

Waste Management
any
Target: Municipal waste incineration plant

If you are an incineration plant operator dealing with rising landfill taxes and disposal fees — this project developed software to evaluate the utilization potential of your ash. This reduces the volume of waste you must landfill and recovers valuable metals and rare earth elements. It turns a waste cost into a revenue stream.

Water Treatment
SME
Target: Industrial adsorbent producer

If you are a water treatment company dealing with the high cost of filter media — this project developed ash-based adsorbents for wastewater treatment. This provides a cheaper, circular alternative to traditional filtering materials. It improves resource efficiency in water purification.

Frequently asked

Quick answers

How does this affect the cost of waste disposal?

Based on available project data, the project aims to reduce costs associated with increasing waste taxes and disposal fees by decreasing the amount of ash sent to landfills.

Is this technology ready for industrial scale?

Yes, the project implements regional real-scale pilots and replication cases across 8 countries to demonstrate the technology in real-world settings.

What are the IP and licensing options for the software?

Based on available project data, the project developed software for ash producers to evaluate utilization potential, but specific licensing terms are not detailed.

What regulations impact the market entry of these products?

The project addresses the lack of uniform regulations and the need for public acceptance regarding the safety and environmental impact of ash-based products.

How is the supply chain managed?

The project created an optimization model to compare centralized and decentralized ash supply chains to determine the most cost-effective logistics.

Consortium

Who built it

The consortium is heavily weighted toward commercial application, with 19 industry partners (63% of the group), including 10 SMEs. This high industry ratio, combined with 7 universities and 1 research center across 8 countries, suggests the project is focused on market viability and industrial scaling rather than pure academic research.
