Waste Heat Recovery and Industrial Heat Pump Application

Engineering-based assessment of waste heat potential in industrial facilities and analysis of electric heating scenarios.

Recarbeng identifies thermal energy currently discharged by industrial facilities, evaluates technical integration routes and structures heat pump feasibility within a consistent CAPEX/OPEX and CO₂ reduction framework.

This service combines thermal system design, process temperature analysis and energy economics to determine whether waste heat recovery and heat pump electrification are suitable investments for your facility.

Why This Service Matters

Waste heat recovery is not only an energy saving measure. It is a strategic tool for operating cost, carbon intensity, CBAM readiness, energy audits and low-carbon production competitiveness.

Energy Efficiency and Audit Pressure

Large industrial facilities increasingly need to explain energy use, waste heat opportunities and system efficiency with technical data.

Electricity and Gas Price Volatility

Heat pumps powered by renewable electricity can offer hybrid or fully electric heating options that reduce fossil fuel price exposure.

CBAM and Carbon Cost

Waste heat recovery can support CBAM competitiveness for Turkish exporters by reducing product-level carbon intensity.

Typical Project Stages

Stage 1: Pre-Feasibility

Site visit, data collection, waste heat source inventory, high-level integration scenarios, cost and saving estimates.

Stage 2: Detailed Engineering Feasibility

Process temperature profile, heat exchanger and heat pump sizing, COP/SCOP calculation, integration and financial modeling.

Stage 3: Tender Support and Implementation Coordination

Optional. Technical specification, RFQ support, supplier assessment, design review and commissioning support.

Target Facility Types

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.

Identification of significant energy uses supports systematic documentation and assessment of waste heat opportunities.

CBAM and Carbon Pricing

Lower thermal energy intensity matters for reducing product-level embedded emissions and managing carbon cost.

Frequently Asked Questions

What is the minimum facility size?

There is no fixed threshold. Payback depends on temperature difference, heat flow rate, operating hours and nearby heat demand. If integration is simple, smaller heat sources can also be assessed.

Can heat pumps reach industrial temperatures?

High-temperature heat pumps can be used for hot water and steam production in specific applications. However, COP decreases as the temperature lift increases, so selection must be based on real process conditions.

How does waste heat recovery affect CBAM?

Lower natural gas consumption for heating reduces direct emissions. If this reduction is correctly allocated to production, it can help lower product-level specific emissions.

Do you install the equipment?

No. Recarbeng provides feasibility, technical specifications and tender evaluation. Installation is carried out by equipment suppliers, mechanical contractors or facility teams.

What is the typical payback period?

Simple payback generally depends on waste heat temperature, energy prices, capital cost and annual operating hours. In well-matched projects, payback can shorten significantly.

What do we receive at the end of the study?

You receive a waste heat source map, feasible integration scenarios, heat pump suitability assessment, CAPEX/OPEX framework and implementation prioritization.

Next Steps

Let us technically assess the waste heat potential in your facility.

If your facility has compressors, furnaces, dryers, chillers or other heat-rejecting equipment, a pre-feasibility study can be carried out to reduce natural gas consumption, lower operating costs, strengthen ISO 50001 readiness or reduce product-level carbon intensity for CBAM.
