Decarbonization Is the Primary Driver

Companies are adopting WHR technologies to capture excess heat from cement, steel, glass and chemical processes, lowering fossil fuel consumption, shrinking their carbon footprints and complying with stringent emission rules. Advanced heat exchangers transfer residual heat, which reduces emissions, cuts operating costs and supports sustainability goals. This rising focus on efficiency is accelerating large-scale adoption worldwide.

Policy ambition is reinforcing the trend. In November 2024, the United Kingdom announced a Nationally Determined Contribution target to reduce all greenhouse gas emissions by at least 81% by 2035, a commitment that encourages industries and power plants to adopt efficiency solutions such as waste heat recovery. Rising deployment of ORC and other advanced WHR systems across chemical, cement, steel, power generation, biomass, oil and gas, and data center sectors is adding momentum.

High Upfront Capital Remains the Main Hurdle

A key challenge is the high initial capital required for installation and integration. WHR projects involve complex equipment such as heat exchangers, ORC units and specialized piping, and planning, customization and installation timelines add further cost. These factors can prevent small and medium-sized enterprises from adopting systems despite long-term energy savings.

Market players are addressing the barrier with innovative financing, including Energy-as-a-Service agreements and leasing, which allow clients to implement WHR without major upfront expenditure. Standardized modular solutions reduce installation complexity and cost, while collaboration with governments and financial institutions is opening access to subsidies, grants and incentives.

Data Centers Emerge as a New Heat Source

A notable trend is the deployment of WHR in data centers to repurpose excess thermal energy for district heating and commercial uses. Providers are developing solutions that capture low- to medium-temperature heat from server operations and distribute it through local heating networks, turning data centers into decentralized energy contributors that advance urban sustainability and low-carbon objectives. In April 2025, NTT Data launched a project in Berlin that redirects 8 MW of data center heat to a new residential and commercial development, supported by a power-to-heat boiler and hot water storage.

Segmentation

The market is segmented by application into pre-heating systems, electricity generation and others, and by end use into chemical and petrochemical, oil and gas, energy and power, food and beverages, cement, paper and pulp and others. Pre-heating systems dominate because energy-intensive industries use them to improve fuel efficiency and reduce operating costs. The chemical and petrochemical sector leads end uses owing to high demand for process heat recovery and stringent energy efficiency regulations.

Regional Analysis

North America's leadership is attributed to the deployment of advanced WHR solutions and the expansion of large-scale industrial and commercial applications. Investment in magnetic bearing ORC systems is improving reliability, lowering costs and raising energy efficiency, reinforcing waste-heat-to-power adoption. In April 2025, Clean Energy Technologies, Inc. secured USD 400,000 in sales of its magnetic bearing ORC heat recovery solutions and is developing a 350 kW system for industrial and commercial use across biomass, oil and gas, data centers and power plants.

Asia Pacific's 9.02% CAGR reflects rising investment in industrial thermal systems and the expansion of efficiency solutions in the cement, steel, chemical and power generation industries. Adoption of industrial heat recovery boilers, pre-heating systems and waste-to-energy solutions is growing, and firms are integrating WHR into existing equipment to optimize energy use. In February 2024, Kilburn Engineering Ltd acquired M E Energy Private Ltd, a provider of WHR and reutilization systems, to strengthen its thermal engineering portfolio and expand energy-efficient offerings in India. The report also covers Europe, the Middle East and Africa, and South America.

Regulatory Frameworks

In the United States, the Environmental Protection Agency regulates WHR within its energy efficiency and air quality programs and supports deployment through initiatives such as the combined heat and power partnership. In China, the National Development and Reform Commission oversees WHR as part of national energy efficiency and carbon reduction strategies, directing subsidies or mandates for heavy industries in line with the country's dual carbon goals. In India, the Bureau of Energy Efficiency promotes WHR under the Energy Conservation Act, overseeing audits, setting efficiency benchmarks and mandating adoption in energy-intensive sectors through the Perform, Achieve and Trade (PAT) scheme.

Competitive Landscape

Leading companies are implementing large-scale projects to capture unused industrial heat for internal energy needs, integrating advanced ORC systems to generate electricity and support district heating, and optimizing kiln and exhaust operations to maximize recovery. In July 2025, Holcim partnered with E.ON Energy Infrastructure Solutions and Orcan Energy to implement a project at its Dotternhausen cement plant that captures 10 MW from kiln exhaust gases to supply internal processes, district heating and power generation using an eP1000 ORC system.
