The article emphasizes the importance of decarbonizing heavy industries in India to comply with global emission reduction goals and meet sustainability targets. Despite progress in sectors like oil & gas and transportation, industries such as power generation, steel, cement, and chemicals remain challenging to decarbonize. The drive for decarbonization is fueled by environmental concerns, shifting regulations, shareholder demands, and consumer preference for sustainability. To achieve decarbonization targets, industries are urged to adopt innovative strategies. Waste-to-energy solutions, including Biomass/MSW to Power and Waste Heat Recovery Systems, are highlighted for their potential to reduce greenhouse gas emissions. The article also discusses the significance of Net Zero technology like Carbon Capture and Utilization (CCU) in achieving green certifications for industries like steel and cement. Waste Heat Recovery Systems are identified as crucial for capturing lost energy in industries and improving overall sustainability. Moreover, smart asset management systems are recommended to enhance energy efficiency and reduce waste through real-time monitoring and predictive analytics. The article concludes by emphasizing the need for coordinated efforts from policymakers, regulators, technology providers, and industry leaders to fast-track the adoption of clean technologies for decarbonizing heavy industries in India.
