Abstract

Urban waste management presents a significant challenge for densely populated urban environments, particularly in efforts to mitigate environmental impact and maximize energy recovery from waste. This article provides an analysis of the Lower Heating Value (LHV) as a key indicator in assessing the energy potential of urban waste. The research was conducted by testing waste samples prior to entering the main waste processing facility at the Bantar Gebang Waste-to-Energy Plant. The samples were analyzed using proximate and ultimate methods to measure chemical composition and calorific value. The results indicate that the waste treatment process significantly influences LHV. Waste that has undergone several treatment processes or that has been mixed with paper currency exhibited the highest LHV of 2396.8 kcal/kg with an ash content of 0.2743%. Thus, this study offers critical insights for designing more efficient and sustainable urban waste management strategies, as well as maximizing the energy potential of generated waste.
