Context:
India is seeking to strengthen its bioeconomy by promoting bio-based chemicals and enzymes under the BioE3 Policy. This can help reduce dependence on imported petrochemicals, support green industrialisation, and improve value addition from India’s large agricultural base and biotechnology capabilities.
Key Highlights:
What are Bio-based Chemicals?
• Bio-based chemicals are industrial chemicals produced from renewable biological feedstocks such as sugarcane, corn, starch, molasses, agricultural residue, and biomass.
• They act as alternatives to petrochemicals, which are derived from crude oil and natural gas.
• Examples include bio-ethanol, bio-acetic acid, lactic acid, bio-plastics, succinic acid, and citric acid.
What are Enzymes?
• Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.
• They are widely used in industries such as food processing, textiles, detergents, pharmaceuticals, leather, paper, and biofuels.
• Enzymes help reduce energy use, improve process efficiency, and lower the need for harsh chemicals.
India’s Sectoral Potential
• India’s large agricultural base and expertise in fermentation technology make it well-suited for scaling this sector.
• India imported nearly $479.8 million worth of acetic acid in 2023, showing scope for domestic substitution.
• Key Indian companies include Praj Industries, Godrej Industries, Godavari Biorefineries, Jubilant Ingrevia, and StringBio.
• In enzymes, major market players include Novozymes India, DuPont, and BASF SE, which together account for a dominant market share.
Policy and Global Support
• India’s BioE3 Policy prioritises bio-based chemicals and enzymes as part of a broader biomanufacturing strategy.
• Similar efforts exist globally through the EU Bioeconomy Strategy, USDA BioPreferred Program, and China’s bioeconomy plans.
Relevant Prelims Points:
- Bio-based chemicals are chemicals produced from renewable biological resources instead of fossil fuels.
• Enzymes are proteins that act as biocatalysts in living systems and industrial processes.
• Petrochemicals are chemicals obtained from petroleum and natural gas.
• Fermentation is a biochemical process in which microorganisms convert sugars into useful products such as alcohols, acids, and enzymes.
• Bioeconomy refers to economic activities based on the sustainable use of biological resources for food, materials, chemicals, and energy.
• Bio-based products often support goals like decarbonisation, circular economy, and waste-to-wealth.
Relevant Mains Points:
Significance for India
• Can reduce import dependence on petrochemical-based industrial inputs.
• Promotes sustainable industrial growth and supports climate goals.
• Creates additional income opportunities for farmers through biomass and feedstock supply chains.
• Encourages innovation, green jobs, and domestic manufacturing.
• Helps India move towards a high-value bioeconomy and cleaner production systems.
Challenges
• Higher production cost compared to conventional petrochemicals.
• Uncertain availability of feedstock due to seasonal and competing uses.
• Need for shared biomanufacturing infrastructure, logistics, and scaling support.
• Limited market acceptance and lack of strong standards or procurement incentives.
Way Forward
• Develop shared fermentation and biomanufacturing infrastructure.
• Frame clear quality standards, certification, and public procurement support.
• Promote R&D, startup ecosystem, and industry-academia collaboration.
• Ensure sustainable feedstock supply without harming food security or ecosystems.
• Use fiscal and policy support to make bio-based products commercially competitive.
