Introduction
With increasing environmental concerns and stringent regulations, the tyre industry is turning to sustainable practices and innovative recycling technologies. This blog delves into the best practices, global case studies, and strategies that are shaping the future of tyre recycling and value recovery.
We’ll explore various aspects of the tyre industry’s approach to sustainability, including:
- Product Stewardship Schemes
- Innovative Recycling Technologies
- Reverse Logistics
- Enablers for Recycling
Product Stewardship Schemes
Canada
- British Columbia: Adopted Extended Producer Responsibility (EPR) in 2007, with distance-based incentives for tyre recycling.
- Manitoba: Tyre Stewardship Manitoba (TSM) mandates recycling for all new tyres, allocating CAN$6 million annually.
- New Brunswick: Transitioning to EPR, managed by Tyre Recycling Atlantic Canada Corporation (TRACC).
- Ontario: Managed by E-track, requiring 100% tyre collection and 85% recycling by weight.
- Quebec: Focuses on efficient tyre collection with recent fee adjustments and volume-based recycling incentives.
Chile
Chile’s EPR law (2016) mandates tyre producers to finance and manage waste collection, aiming for a 90% collection rate by 2030.
European Union
- Denmark: Tax-financed scheme with producer fees funding recycling.
- Finland: Managed by Finnish Tyre Recycling Ltd., with extensive collection points.
- France: Focuses on high-value recycled products with strong regulatory support.
- Italy: Managed by Ecopneus, includes eco-fees and targets high material and energy recovery.
China
Implemented various regulations to manage the disposal and recycling of ELTs. The Ministry of Ecology and Environment, along with other governmental bodies, sets guidelines and policies to ensure environmentally sound management of waste tyres. China also has numerous recycling facilities that process ELTs into various products, such as rubber powder, reclaimed rubber, and tyre-derived fuel (TDF). These facilities help in reducing the environmental impact of waste tyres.
Innovative Recycling Technologies
Pyrolysis and Devulcanization
Technologies like pyrolysis and devulcanization are at the forefront of tyre recycling.
- Pyrolysis: This process involves heating tyres in the absence of oxygen to break down the rubber into valuable by-products such as oil, gas, and char. Pyrolysis is advantageous for its ability to handle mixed tyre compositions and produce high-quality outputs suitable for various applications.
- Devulcanization: This technology breaks down the sulphur bonds in rubber, allowing the material to be reused in new products. Devulcanization can convert waste tyres into new rubber products, promoting a circular economy within the tyre industry.
Mechanical Recycling
Mechanical recycling involves shredding tyres into smaller pieces to create products like rubber mulch and crumb rubber.
- Rubber Mulch: Used for landscaping and playground surfaces, rubber mulch is a durable and sustainable alternative to traditional materials.
- Crumb Rubber: This material can be used in various applications, from road construction to sports surfaces, providing a market for recycled tyre products and reducing the environmental impact of tyre waste.
Reverse Logistics
Definition and Importance
Reverse logistics involves the process of collecting and transporting EOLTs back to recycling facilities. Efficient reverse logistics systems are crucial for managing tyre waste, particularly in countries with vast and remote areas like Australia and Canada.
Global Examples
Countries like Chile and Finland have implemented successful reverse logistics models:
- Chile: Chile’s EPR law includes specific requirements for reverse logistics, ensuring that tyres are collected from remote locations and transported to recycling facilities. This system supports the country’s ambitious tyre recycling targets.
- Finland: Finland’s tyre recycling programme includes a well-coordinated reverse logistics system, with designated collection points and efficient transportation networks to ensure that tyres are recycled effectively.
Enablers for Recycling
Waste Classification and Standards
Standardizing waste classifications and quality standards across regions is essential for effective tyre recycling. Consistent tracking and traceability mechanisms are necessary to monitor the movement of tyre waste and ensure compliance with recycling regulations.
Recycling Hubs and Industrial Symbiosis
The creation of recycling hubs, where tyre recyclers and industries consuming tyre-derived products coexist, supports technology development and the conversion of waste into valuable products. These hubs promote industrial symbiosis, where the waste from one industry becomes a resource for another, enhancing the efficiency and sustainability of tyre recycling operations.
Conclusion
The tyre industry is making significant strides in adopting sustainable practices for managing EOLTs. By learning from global case studies and implementing innovative technologies, the industry can move towards a circular economy, reducing waste and conserving resources.
