Zero Waste Index-Based Waste Management Planning for a Government Office: A Case Study of DLHK D.I. Yogyakarta
Keywords:
Abstract
Background: Effective waste management at the source is essential to reduce waste generation and minimize waste disposal in landfills. The Zero Waste Index (ZWI) provides an approach for evaluating waste reduction and resource recovery.
Aims: This study aimed to develop a waste management plan for the office area of the Department of Environment and Forestry of the Special Region of Yogyakarta (DLHK D.I. Yogyakarta) using the Zero Waste Index approach.
Methods: Waste generation and composition were measured based on SNI 19-3964-1994. The waste generation rate, composition, Zero Waste Index, substituted energy, and area required for the temporary waste storage facility (TPS) were determined. A residual plastic waste substitution program using plastic-based paving blocks was also proposed and projected over two years.
ResultS & Conclusion: The average waste generation was 22.52 kg/day, with garden organic waste as the dominant component (13.85 kg/day). Waste generation was 0.06 kg/person/day, with a volume of 1.1 L/person/day. The waste composition consisted of 61.4% organic waste, 24.4% mixed residual waste, 9.4% paper, 2.3% recyclable plastic, and 2.3% glass. The initial ZWI was 49%, with 39.28 MJ of substituted energy, while the required TPS area was 39 m². A two-year projection with the proposed plastic waste substitution program increased the ZWI to 66%, with substituted energy reaching 99.54 MJ. The results indicate that the proposed waste management plan can improve waste recovery and reduce waste disposal.
