Aluminium Production and Processing Facilities
Aluminium extrusion, casting, melting, heat treatment, ageing furnaces, anodizing and surface treatment lines generate significant waste heat. Furnace flue gases, compressor systems, cooling circuits and hot process baths can be assessed for energy recovery.
Recarbeng analyzes waste heat sources in aluminium facilities together with process temperatures, operating hours and production patterns. Recovered heat can be evaluated for process preheating, wash water heating, boiler feedwater preheating, hot water production or heat pump integration.
In aluminium, energy efficiency does not only reduce operating cost. It also creates strategic value by lowering product-level embedded emissions and supporting CBAM cost risk management.
Iron, Steel and Metallurgy Facilities
Iron and steel, rolling, casting, heat treatment, annealing, drying and surface treatment processes can have high-temperature waste heat potential. Furnace flue gases, hot product cooling areas, compressor systems, cooling water and exhaust air can be assessed within this scope.
In these facilities, waste heat recovery can be used to reduce fuel consumption, provide process preheating, generate hot water, support steam systems or enable hybrid heat pump applications. Recarbeng evaluates recoverable heat amount, technical integration options and the economic return of the investment with an engineering-based approach.
Because iron and steel are directly affected by CBAM, reducing energy intensity is critical for both cost control and competitiveness in the EU market.
Cement and Lime Plants
Cement and lime production are among the most relevant sectors for waste heat recovery due to high-temperature processes and continuous operation. Rotary kilns, clinker coolers, flue gases, drying lines and auxiliary energy systems carry significant thermal energy potential.
Waste heat can be assessed for raw material pre-drying, process water heating, power generation, low-temperature heat demand or district heating scenarios. Where appropriate, organic Rankine cycle systems, heat exchangers and industrial heat pump solutions can be compared from technical and economic perspectives.
Cement is a priority sector in carbon management due to high process emissions. Waste heat recovery does not eliminate process emissions directly, but it can reduce energy-related emissions and operating cost, supporting the wider decarbonization roadmap.
Fertilizer and Chemical Plants
Fertilizer and chemical plants can offer major energy recovery opportunities through steam systems, reactors, dryers, compressors, condensers, cooling towers and process waste streams. Especially in continuously operating processes, low- and medium-temperature waste heat sources can become economically relevant.
Recarbeng maps heat sources and heat demands together in these facilities. Waste heat can be used for process preheating, boiler feedwater heating, drying air preheating, hot water production or heat pump temperature upgrading.
Since fertilizer is within the CBAM scope, reducing energy consumption and carbon intensity is an important part of financial risk management for producers exporting to the EU.
Hydrogen Production and Auxiliary Energy Systems
Hydrogen production facilities can have waste heat potential from electrolyzers, reformer systems, compressors, gas cooling circuits, purification systems and auxiliary equipment. Electrolyzer cooling circuits and compressor waste heat should be reviewed in particular for low- and medium-temperature heat recovery.
This waste heat can be used for internal hot water demand, process preheating, building heating, drying processes or district heating connections. Heat pump integration can raise low-temperature waste heat to more useful temperature levels.
Hydrogen is a sensitive area for energy efficiency because of low-carbon production targets and EU supply chain expectations. Recarbeng evaluates energy recovery potential in hydrogen facilities in terms of technical feasibility, electricity consumption, CO₂ impact and investment return.
