The chemical industry is undergoing a significant transformation towards sustainability by integrating renewable energy and bio-based chemicals to reduce carbon emissions. Innovations in Engineering, Procurement, and Construction (EPC) for renewable-to-chemical processes are highlighted, showcasing the potential for sustainable growth and environmental preservation. Bio-based chemicals, produced from renewable biological resources, offer a promising alternative to petrochemicals by utilizing waste streams efficiently. Case studies demonstrating the production of bioethanol from rice straw and ethylene from food waste emphasize the benefits of sustainable technologies in transforming agricultural waste into valuable energy resources. The integration of renewable energy sources, such as Indian Oil Corporation Limited's bio-ethanol plant project and India's hydrogen infrastructure development, promotes cleaner production processes and transportation options. Government support, through initiatives like carbon capture and utilization centers, and global collaborations in the renewable chemicals sector are driving technological advancements and market expansion. The future of the chemical industry lies in embracing renewable energy sources, sustainable practices, and international partnerships to achieve significant reductions in carbon emissions while meeting the growing demand for chemicals. The role of EPC in facilitating these transitions is crucial for a more sustainable and resilient chemical industry, positioning it to lead the charge towards a greener future amidst global efforts to address climate change and promote sustainable development.
