Waste to Energy
Reliable Refractory Materials for High-Performance Energy Recovery
Waste-to-energy systems operate under constant thermal, chemical, and mechanical stress, requiring materials that can endure extreme conditions. To meet these challenges, we develop silicon carbide (SiC) solutions tailored for high-performance in demanding environments. Our portfolio of bricks, tiles, refractory blocks, and tube wall protection systems delivers a balance of thermal conductivity and structural strength to support combustion stability, improve energy recovery, and safeguard critical infrastructure.
Each solution is precisely designed to fit both new installations and retrofit projects. Supported by expert technical guidance, our SiC technologies help reduce maintenance needs, extend service life, and maintain high performance even in the most demanding operating environments.
