The increasing generation of waste, driven by urbanization and population growth, necessitates innovative approaches for sustainable waste management. This thesis focuses on addressing the challenges associated with organic waste, the largest fraction of municipal solid waste globally, by developing and optimizing electrical composters (EC) alongside automated waste segregation systems. The research evaluates these technologies through environmental and economic lenses to support their integration into sustainable waste management strategies. A patent review revealed a growing trend toward automated aerobic composting systems, highlighting their cost-effectiveness and faster processing times. However, effective waste segregation was identified as a critical prerequisite for optimizing composting efficiency. To address this, an automated waste segregator was developed using physical sensors and Al-driven image classification (Inception-v3 model), achieving an accuracy of 86.7%, with notable improvements in the classification of metal and glass waste. Building on this foundation, the influence of C/N ratios on compost maturity was examined, revealing the need for extended curing periods to produce agriculturally viable composts. Electrical composters accelerated thermophilic and mesophilic phases but required additional curing to achieve maturity. Immature compost samples demonstrated low germination indices, underscoring the importance of refining composting processes. Environmental and economic analyses compared EC and bin composting (BC) systems integrated with landfilling. From an environmental impact assessment (EIA) perspective, BC integrated with landfilling demonstrated superior performance, reducing net greenhouse gas (GHG) emissions by 296% relative to traditional landfilling. This substantial reduction is due to both lower direct emissions and significant avoided emissions from fertilizer substitution, resulting in net-negative emissions of - 6.26M tonnes CO-eq compared to the 3.18M tonnes COz-eq emitted by traditional landfilling. Conversely, solar-powered EC achieved a 111% reduction, resulting in net-negative emissions of -0.35M tonnes COs-eq, showcasing the potential of renewable energy in enhancing EC systems. From a life cycle cost analysis (LCCA) perspective, BC was consistently more cost-effective, with total costs for landfilling plus BC reduced to approximately BND $595M under a 70% equipment cost reduction scenario, compared to over BND $845M for EC. These findings reveal a trade-off between environmental and economic performance, with BC excelling in cost-effectiveness and EC demonstrating greater environmental potential when powered by renewable energy. This thesis advocates the adoption of electrical composters as part of an integrated waste management framework. By leveraging advancements in automation, renewable energy, and optimized composting processes, EC systems align with circular economy principles, offering a pathway to reduce landfill dependency, lower GHG emissions, and recover valuable resources. Policymakers are urged to prioritize renewable energy integration, cost-reduction strategies, and public awareness initiatives to facilitate the transition toward sustainable and resilient waste management systems.
