Abstract
The Indian chemical industry, projected to reach $1 trillion by 2040, stands at a pivotal moment where sustainability, innovation, and operational efficiency converge to shape its future. Transitioning towards greener chemicals and sustainable supply chains is no longer solely a regulatory requirement—it is a strategic business imperative. By leveraging green chemistry, biotechnology, and circular economy principles, manufacturers can reduce environmental impact while enhancing product efficiency and market competitiveness. Simultaneously, operational sustainability—including energy efficiency, waste and effluent management, and emissions reduction—drives cost savings, global credibility, and long-term resilience. Through targeted R&D, collaborative partnerships, and systemic reforms, India’s chemical sector can simultaneously advance economic growth, climate responsibility, and global supply chain integration.
Introduction
With an estimated CAGR of 9% to 10%, the Indian Chemical Industry is projected to reach a market size of USD 1 trillion by 2040.[1] As the industry transitions toward a high-tech, low-carbon future, the focus must shift to cost efficiency, end-market adaptability, innovation, and sustainability to navigate this dynamic landscape. This transformative journey positions the sector as a key player in shaping the global supply chain.
An important pillar of the national economy – sixth-largest producer of chemicals globally and the third-largest in Asia employing more than 2 million people[2], the industry must be able to sustain its growth and gain greater global competitiveness. Sustainability and circularity are becoming core business strengths, both domestically and on the international market. Historically, chemicals manufacturers have received a lot of flak for high emissions and pollution-intensive production. In the past few decades, notable efforts have been made across the board to reform the industry and deepen its sustainability measures.
While many decarbonisation efforts have sprung from compliance and regulatory requirements, it is now becoming increasingly clear that green practices are not only good for the environment and climate but also make for better business. Firstly, it aligns with the changing trends in consumer preferences for eco-friendly products, and secondly, innovations in green chemistry and biotechnology are resulting in more natural, gentle products that are as efficient as petro-based products.
Incorporating circularity into chemicals manufacturing requires a holistic approach, from improved R&D, greener production, and better supply chain management. It’s also important to remember that sustainability is not a one-size-fits-all principle, and solving specific challenges is necessary to effectively decarbonise within particular operational and regional contexts.
Towards greener and better chemicals
The work of sustainability begins right at the foundation. Chemicals are building blocks of countless products and items. Making chemicals eco-friendly has a ripple effect, increasing the sustainability of the end product.
The use of green chemistry and biotechnology creates chemicals that are more natural and less toxic. These use renewable feedstock, such as plant matter and agricultural by-products, along with biological processes such as fermentation, instead of fossil fuels and chemical synthesis. As investment in R&D for green chemistry deepens, we are able to create chemicals that are just as, if not more, efficient than conventional petrochemicals. Making them cost-effective and viable at a larger commercial scale requires not only increased investment but also systemic reforms, policy support, and infrastructural upgrades. This is a strategic national imperative as well: increasing our capabilities for green, speciality chemicals can help India become embedded in global supply chains, especially with dynamic geopolitical changes. Ecosystem-wide collaborations and stronger public-private partnerships are necessary to support India’s green chemicals growth, towards economic growth and climate resilience.
Sustainability at the backend
Beyond decarbonising chemicals, operations and manufacturing have a huge role to play in making businesses greener. The first step is to conduct thorough and regular sustainability audits through a 360-degree approach. This helps assess gaps, align business planning with ground-level challenges, and identify opportunities for improvement. It also helps provide a comprehensive view of the business and supply chain, which aids in compliance and reporting. Crucially, such audits help businesses ascertain the impact of their activities on local communities and the environment. Such insights are vital for creating organisation-specific decarbonisation targets and strategies.
Operational and manufacturing sustainability is multi-faceted. The four key dimensions are energy, water, emissions, and waste. Manufacturing chemicals is a resource and energy-intensive process, making it essential to consider operational efficiency as a key sustainability measure in the chemicals sector.
Energy efficiency must be pursued through the conservation of energy and adoption of renewable energy. This requires both R&D to innovate less energy-intensive processes as well as infrastructural improvements to widen accessibility and affordability of clean energy. This is only possible through collaborative initiatives by chemicals manufacturers, industry bodies, and policymakers.
Waste and effluent management is another important concern. Ensuring that wastewater is reused and treated with minimal chemical intervention is essential to safeguard the health of the environment and local water bodies. This underscores the immense importance of continuous R&D for sustainability: advanced electromagnetic and ionized processes efficiently treat wastewater but also conserves energy compared to conventional treatments.
Reducing emissions and improving waste management through internationally recognised strategies can yield credible results. Adopting the 5S approach to waste management can help organisations structure their sustainability measures instead of sporadic and isolated initiatives. The 5S system includes sorting out unnecessary items, implementing a better ordering system, prioritising cleanliness, maintaining high standards of working, and training employees to implement the system autonomously. Certification of 5S standards can build global credibility in an organisation’s ways of working, which is crucial for Indian manufacturers seeking to expand their international presence.
Greener business and supply chains, while long-term ambitions, boil down to small and steady steps. The journey to decarbonisation is long, which is why it’s critical to begin with a sharp understanding of one’s particular business environment and operational context. Setting high, yearly organisational targets towards energy efficiency, water positivity, and green processes will help businesses unlock accelerated growth towards profitability and sustainability in a dynamic global economy. Top management commitment and leadership will be critical for success.
Conclusion
Decarbonising the chemical industry requires a holistic, multi-layered approach, encompassing greener products, efficient operations, and sustainable supply chains. While the journey is long and complex, incremental steps—such as adopting renewable energy, implementing advanced wastewater treatment, and embedding circularity in manufacturing—can yield measurable impact. Strategic investment in green R&D, strong public-private partnerships, and leadership commitment are essential to drive these changes. Ultimately, sustainability is not just an environmental responsibility but a business advantage: it enhances competitiveness, aligns with evolving consumer preferences, and positions India as a global leader in green chemicals and resilient supply chains.
