Sustainable ceramic filters made from waste for high-temperature processes

June 12, 2026

A Spanish technology center is developing porous ceramic filters for industrial waste up to 500 degrees Celsius, which are characterized by high mechanical strength and structural integrity. The filters are manufactured from waste streams from the ceramics industry; after conditioning (grinding, classifying, and homogenizing), they are extruded, dried, and sintered to achieve controlled porosity.
Unlike expensive technical ceramics, traditional silicon-aluminum matrix systems made from secondary raw materials are used, which reduces costs and promotes the circular economy.

Advantages

The solution is suitable for gas filtration, thermal protection, or component protection in industries such as metallurgy, waste treatment, and cement, and has been validated at TRL 7–8 with pilot plants.

Partner and Collaboration Opportunities

We are seeking manufacturers of ceramic filters for scaling up extrusion, engineering firms for system integration into filtration systems, and industrial end-users for field testing. We are seeking commercial agreements with technical support as well as licensing agreements for manufacturing and marketing.
