Tracing the EoL Tyre Management Chain in Togo with Focus on Implementing a Tyre Recycling Plant

Abstract

As part of the “Waste2Energy: hybrid energy from waste as a sustainable solution for West-Africa” project, a tyre recycling plant is being constructed in Davié, north of Lomé, Togo. Understanding the tyre management chain is crucial for establishing the plant’s supply chain. This study aimed to highlight the gaps in and the importance of tyre recycling in Togo while assessing the potential of EoL tyres for the implementation of a tyre recycling plant. Togo’s vehicle fleet, predominantly concentrated in Lomé, is rapidly increasing at a rate of 6% per year, reaching an estimated 285,000 vehicles. Due to economic constraints and limited new tyre availability, most vehicle users opt for used tyres, which have a limited lifespan due to poor road conditions. An investigation of EoL tyre quantities and management chains in Togo was carried out. To evaluate the used and end-of-life tyre management chains, both direct observation and interviews with approximately 200 used-tyre dealers were conducted. The study revealed that, on average, drivers replace tyres every 7.4 months, generating between 30,525 t/a and 78,000 t/a of used tyres, 75% of which are replaced due to severe damage or wear. While the used tyre business is well organized, end-of-life tyre treatment is nearly non-existent, often involving dumping, open burning for metal recovery, or use in meat processing, causing environmental and health risks. To address these challenges, an 8 t/hr capacity tyre recycling plant is planned, based on estimated tyre availability and development opportunities for sustainable recycling in Togo.
