摘要

由于废物管理基础设施不足,小岛屿发展中国家(SIDS)在管理家庭固体废物方面面临着长期挑战。本研究通过废物特征调查 (WACS) 和生命周期评估 (LCA),以及地理信息系统 (GIS) 分析,调查了斐济纳西努镇政府现有的固体废物管理做法,以评估潜在的废物处理设施。对各种策略进行了探讨,包括回收无机废物和将有机废物转化为能源。垃圾填埋场气体回收被认为是减少二氧化碳 (CO₂)、一氧化二氮 (N₂O) 和甲烷 (CH₄) 等有毒气体排放的重要因素。此外,处理有机废物还可减少垃圾填埋量,最大限度地减少污染物的排放。该研究强调了支持性政策对有效管理固体废物的重要性,并重点介绍了有机废物处理如何改善纳西努镇的废物管理。这项研究在小岛屿发展中国家的研究中是独一无二的,它提供了宝贵的见解和可复制的技术,适用于研究地区和更广泛的太平洋地区,有可能显著改善固体废物管理实践。

Enhancing Solid Waste Management in Fiji: A Comprehensive Approach with LCA, GIS, and Waste Treatment Strategies

Enhancing Solid Waste Management in Fiji: A Comprehensive Approach with LCA, GIS, and Waste Treatment Strategies

Small island developing states (SIDS) face persistent challenges in managing household solid waste due to inadequate waste management infrastructure. This study investigates the existing solid waste management practices in Nasinu Town Council, Fiji, through waste characterization survey (WACS) and life cycle assessment (LCA), accompanied by geographic information system (GIS) analysis to evaluate potential waste treatment facilities. Various strategies are explored, including recycling inorganic waste and converting organic waste into energy. Landfill gas recovery is identified as a significant contributor to reducing toxic gases like carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄) emissions. Furthermore, treating organic waste reduces landfill volume and minimizes the release of pollutants. The study emphasizes the importance of supportive policies for effective solid waste management and highlights how organic waste treatment can improve waste management in Nasinu Town. This research, unique among SIDS studies, provides valuable insights and replicable technologies applicable to the study area and the broader Pacific Region, with the potential to significantly improve solid waste management practices.
