Waste tyres are problematic as disposal is difficult. Open dumping is hazardous due to the flammability of rubber (Mohammad et al., 2023).Tyre dumps also serve as mosquito-breeding sites in tropical climates (Jimoda et al., 2018; Rajesh et al., 2013).The leaching of contaminants such as metals and polyaromatic hydrocarbons (PAH's) can occur from …
