Waste Heat Recovery in Industrial Processes: Enhancing Energy Efficiency<br /><br />By: Eng. Abdullah Marza Hamza<br /><br />Sustainable Development Goals (SDGs) Addressed:<br /> Goal 9: Industry, Innovation and Infrastructure<br /> Goal 12: Responsible Consumption and Production<br /> Goal 13: Climate Action<br /><br />Industrial facilities consume vast amounts of energy, often releasing a significant portion as waste heat. Waste Heat Recovery (WHR) technologies aim to capture this unused energy and convert it into useful work, thereby enhancing overall efficiency.<br /><br />Common methods include heat exchangers, organic Rankine cycles (ORC), and thermoelectric generators. WHR is widely applied in industries like steel, cement, glass, and chemical manufacturing.<br /><br />By reusing energy that would otherwise be lost, industries reduce fuel consumption, operating costs, and greenhouse gas emissions. WHR also improves sustainability without compromising productivity.<br /><br />Challenges involve matching heat source and sink temperatures, system integration, and cost justification. Nonetheless, WHR remains a key strategy for cleaner industrial operations.<br /><br />Al-Mustaqbal University – The No. 1 Private University in Iraq
