Measures for CO₂-neutral brick production – handout for practitioners

This handout presents practical measures for reducing CO₂ emissions in brick production at Lingl Solead. The following approaches significantly increase energy efficiency and reduce emissions:

Decoupling of kiln and dryer: Reduction of heat losses through separate systems and optimized heat management.

Extended heating and cooling zones: More uniform temperature control and avoidance of energy peaks.

Circulation systems for heat recovery: Efficient heat distribution through targeted air circulation.

Preheating of combustion air (up to 450 °C): Higher combustion efficiency and lower fuel consumption.

Minimization of heat loss: Improved insulation of kiln cars, doors, walls, and ceilings.

Exhaust gas heat exchangers: Use of exhaust gas heat to preheat combustion air or process air.

Alternative heating methods: Use of renewable energies and low-CO₂ fuels.

Result:

The combination of these measures enables energy savings and CO₂ reductions of up to 50%, making Lingl Solead’s production processes more sustainable and efficient.
