The Potential of Latex Waste Sludge as an Alternative Fuel Briquettes

Abstract

This study investigates the conversion of latex waste sludge, a valueless byproduct from rubber manufacturing, into sustainable fuel briquettes. With increasing environmental concerns and energy demands, repurposing industrial waste offers promising alternatives to conventional waste management while reducing dependence on fossil fuels. Using a systematic experimental approach with 3 levels, 2 factors, and 3 replications, we determined optimal formulations for briquette production. The study evaluated various mixing ratios of latex waste sludge with rubber leaves and rubber leaf charcoal. All produced briquettes underwent comprehensive analysis for key parameters, including heating value, moisture content, ash content, volatile matter, and fixed carbon content. Results demonstrated that incorporating rubber plant biomass significantly enhanced the briquettes' fuel properties. The addition of rubber leaves increased heating values and fixed carbon content while decreasing ash content. Furthermore, using rubber leaf charcoal instead of raw leaves substantially improved combustion efficiency and reduced soot and ash production. However, rubber leaf content exceeding 35% compromised briquette structural integrity. The optimal formulation contained 83% latex waste sludge and 17% rubber leaf charcoal by mass. This composition achieved the best balance of thermal performance, structural stability, and reduced emissions. This research contributes to circular economy principles by transforming industrial waste into valuable energy resources. The findings suggest that latex waste sludge, previously considered worthless, can be effectively upcycled into efficient fuel briquettes, providing sustainable solutions for both waste management and alternative energy development.
