India’s growing tyre waste problem is an increasingly urgent environmental concern. Tyre waste in the country is mounting due to the rapid growth in vehicle ownership, particularly in urban areas, along with poor disposal practices. Tyres are made from synthetic rubber, steel, and other materials, making them extremely difficult to break down naturally, and improper disposal leads to environmental pollution.
To tackle this mounting tyre waste, India can consider a mix of technological, regulatory, and community-based solutions:
1. Recycling and Repurposing
- Mechanical Recycling: A method where tyres are shredded into smaller parts and can be reused for products such as rubber mats, playground surfaces, road construction, or as fuel for industrial plants. India already has some capacity for tyre recycling, but it needs significant scaling up.
- Devulcanization: This involves breaking the sulphur bonds in rubber to restore it to a usable state. This would allow recycled rubber to be reused in high-quality products. Research and development in this area could be vital.
- Rethreading: A practice that involves replacing the worn-out tread of tyres with new rubber, allowing tyres to be reused for a longer period before disposal. Rethreading is common in commercial vehicles and could be expanded to passenger vehicles.
2. Improved Disposal Regulations
- Extended Producer Responsibility (EPR): Manufacturers of tyres should be mandated to take responsibility for the end-of-life disposal of their products. EPR programs incentivize producers to invest in better recycling systems and reduce waste.
- Tougher Enforcement of Waste Management Laws: India’s existing waste management laws can be strengthened to ensure proper collection, recycling, and disposal of tyres. Enforcement can be improved through increased monitoring and penalties for improper disposal.
- Tracking Systems: Implement systems to track tyre disposal, similar to the way electronic waste (e-waste) is tracked. This would help ensure tyres are disposed of properly and recycled rather than dumped in landfills or burned.
3. Public-Private Partnerships
- Investment in Recycling Infrastructure: Private companies, local governments, and NGOs can collaborate to set up efficient tyre recycling plants. A public-private partnership (PPP) could help establish a system for nationwide tyre collection and recycling.
- Use of Tyres in Road Construction: India has already seen some experimental use of shredded tyres in road construction to improve the durability and reduce costs. Scaling this approach up could help mitigate waste while enhancing infrastructure.
4. Energy Recovery (Waste-to-Energy)
- Incineration for Energy: Tyres can be burned in specialized plants to generate energy. However, this requires careful management to control emissions and minimize environmental impact. India already has a few cement plants that use tyres as a substitute for coal, and this practice can be expanded.
- Pyrolysis: This is a thermal decomposition of tyres in the absence of oxygen, which produces oil, gas, and carbon black. The resulting oil can be refined and used as an alternative fuel, while the carbon black can be recycled for industrial uses.
5. Awareness Campaigns
- Public Education: Increasing awareness about the environmental risks of improper tyre disposal can encourage individuals and businesses to adopt more sustainable practices.
- Incentivizing Proper Disposal: Local governments can offer incentives to consumers for turning in old tyres to designated recycling centres.
6. Innovative Alternatives to Traditional Tyres
- Biodegradable Tyres: Encouraging research into the development of eco-friendly, biodegradable tyres could be a long-term solution. Companies are beginning to experiment with plant-based materials and alternative rubber products to reduce environmental impact.
- 3D Printed Tyres: Though still in early stages, 3D-printed tyres that use less raw material could also be an option to reduce tyre waste.
7. Community-Driven Solutions
- Local Recycling Initiatives: Small-scale, community-driven recycling initiatives, like turning tyres into urban furniture, garden pots, or art, can help address local waste issues and raise awareness about tyre recycling.
- NGO Involvement: NGOs and grassroots organizations can play a crucial role in spreading awareness, collecting tyres for recycling, and running education campaigns on the dangers of tyre waste.
8. Collaboration with International Bodies
- Global Best Practices: India can collaborate with international organizations such as the United Nations Environment Programme (UNEP) or the Global Alliance of Tire Manufacturers (GATM) to implement best practices for tyre waste management, leveraging knowledge and technologies that have proven successful in other countries.
Conclusion
Tyre waste management in India needs a holistic approach that combines effective waste regulations, improved recycling systems, public awareness, and technology innovation. While the situation is daunting, with strategic planning and collaboration, India can significantly reduce its tyre waste and move toward a more sustainable model of consumption and disposal.
