Abstract: Handling bio-waste becomes harder as cities expand, and a number of efforts now try to make the process smarter through sensors, optimization, better treatment planning and policy design. This review looks at five selected scholarly works that cover different parts of the problem: an IoT-based intelligent waste management system for smart cities, a location-allocation model for treating hotel bio-waste on site, a smart-bin study carried out in ten hospitals, a review of thirteen biowaste treatment technologies, and an edited volume on composting through nexus thinking. The literature suggests that sensing and optimization can cut energy use, data gaps and transport effort, but that these gains depend on what comes after collection: which treatment technology is chosen, where facilities are sited, whether the products can be sold, and whether policy backs the whole chain. We compare the methods and limits of the works, point out gaps, and propose directions for a smart bio-waste management system. Since the review rests on five selected works and not on a database search, it is a focused narrative review and not a systematic one.
