Biomaterials and Their Role in Sustainable Manufacturing
Post Date: 10-Jan-2026
GS-3 | Economy | Environment
đź“Ť In News
Biomaterials are emerging as a central pillar in the transition towards sustainable manufacturing, as countries seek alternatives to fossil-based materials to reduce environmental impact and strengthen circular economies.
🧬 What are Biomaterials?
Biomaterials are materials derived wholly or partly from biological sources, or engineered using biological processes, designed to replace or interact with conventional materials.
They are increasingly used across sectors such as:
- Packaging
- Textiles
- Construction
- Healthcare
Examples include:
- Bioplastics derived from plant sugars or starch
- Bio-based fibres in textiles
- Medical biomaterials such as biodegradable sutures and tissue scaffolds
🧩 Categories of Biomaterials
1. Drop-in Biomaterials
- Chemically similar to petroleum-based materials
- Can be used in existing manufacturing systems without major changes
2. Drop-out Biomaterials
- Require new processing, handling, or disposal systems
3. Novel Biomaterials
- Offer entirely new properties or functions, beyond conventional materials
🌱 Importance and Need (India Focus)
Biomaterials enable India to achieve multiple objectives simultaneously:
- Promote environmental sustainability and climate action
- Support industrial growth and revenue generation
- Reduce dependence on fossil-based imports for plastics and chemicals
- Add value to agricultural feedstocks and residues, enhancing farmer incomes
- Strengthen competitiveness as global markets shift to low-carbon and circular products
- Align with domestic policies such as single-use plastic bans and waste reduction goals
🌍 Global Scenario
European Union
- Adopted the Packaging and Packaging Waste Regulation (EU) 2025/40 (PPWR)
- Recognises that compostable packaging has demonstrable environmental benefits for specific uses
United Arab Emirates
- Positioning itself as a major biomaterials manufacturing hub
- Emirates Biotech plans a PLA plant using Sulzer technology
- Two phases of 80,000 tonnes/year each
- Operations expected to begin in 2028
- Will be the world’s largest PLA facility when fully operational
United States
- Leader in transformative biomaterials technologies
- Strong policy push through USDA’s BioPreferred Program, leveraging federal procurement
🇮🇳 Present Status in India
- India’s biomaterials sector spans bioplastics, biopolymers, and bio-derived materials
- Bioplastics market valued at about $500 million in 2024, with strong growth prospects
- Major investments include Balrampur Chini Mills’ PLA plant in Uttar Pradesh
- Domestic innovation ecosystem:
- Phool.co converting temple flower waste into biomaterials
- Praj Industries operating a demonstration-scale bioplastics plant
⚠️ Issues and Concerns
Despite strong potential, challenges remain:
- Feedstock scaling may compete with food crops
- Intensive agriculture risks water stress and soil degradation
- Limited waste management and composting infrastructure
- Fragmented policies across agriculture, environment, and industry
- Delayed action may increase import dependence as global competitors advance
đź”® Conclusion & Way Forward
To fully harness biomaterials, India must:
- Expand biomanufacturing infrastructure
- Improve feedstock productivity using advanced technologies
- Invest in R&D, standards, and certification frameworks
- Establish clear regulations, labelling norms, and end-of-life pathways
- Use government procurement, targeted incentives, pilot plants, and shared facilities to reduce early investment risks
