Abstract
As part of the Australian Government’s National Environmental Science Program Sustainable Communities and Waste Hub, CSIRO and Curtin University reviewed international best practice case studies for overcoming barriers and increasing value recovery from end-of-life tyres (EOLTs) and conveyor belts in Australia. The case studies included: • product stewardship schemes, enablers and technologies for value recovery from EOLTs and conveyor belts • end markets for tyre-derived products • strategies for communicating with Indigenous communities. Key recommendations included: • enacting a regulated stewardship scheme to capture all tyres • introducing a recycling fee as part of the price of new tyres and conveyor belts • banning landfilling and on-site disposal of EOLTs and conveyor belts. The stewardship scheme could also be extended to include rubbery conveyor belts, which are currently not considered a controlled waste. Enablers are critical to the successful development of recycling technologies and market pathways. They include consistent waste classifications, quality standards, traceability and enhanced collaboration across the value chain. Recycling hubs or ecosystems would allow tyre recyclers and industries that consume tyre-derived products and fuels to co-exist. Creating and supporting these facilities allows technology development and conversion of rubber waste to valuable products to support circularity. Reverse logistics will likely play a crucial role in managing rubber waste, facilitated through the adoption of Industry 4.0 technologies. Prioritisation and investment into technologies should be aligned with circular economy principles. This will be enabled through holistic value chain assessments such as value retention models, cost/benefit comparison, life cycle assessment and material circularity indicators.
