1.1 Overview of Waste-to-Energy (WtE) and Its Significance
Waste-to-Energy (WtE) stands at the forefront of innovative and sustainable approaches to addressing the dual challenges of waste management and energy generation in our rapidly urbanizing world. As urban populations burgeon and cities grapple with mounting waste volumes, the concept of converting this waste into a valuable energy resource gains paramount importance. Waste-to-Energy involves the conversion of various types of waste materials—ranging from municipal solid waste to agricultural residues—into heat, electricity, or fuel through various technological processes. The significance of Waste-to-Energy lies in its multifaceted impact, offering a viable solution to the escalating waste crisis while contributing to the diversification of energy sources and reduction of greenhouse gas emissions. In the context of Smart Cities, where the integration of technology and sustainability is a paramount goal, Waste-to-Energy emerges as a linchpin for achieving intelligent waste management and decentralized power generation. The utilization of waste as a resource aligns with the circular economy principles, minimizing environmental impact and fostering a more sustainable energy landscape. Hussain, Mishra and Vanacore (2020) present a case study on the implementation of anaerobic digestion in order to achieve a waste to energy and circular economy.
The integration of Waste-to-Energy into the fabric of Smart Cities holds the promise of transformative change, offering a dynamic approach to waste management that goes beyond the traditional linear model of disposal. By harnessing the potential of Internet of Things (IoT) and Machine Learning (ML), cities can revolutionize how they collect, sort, and convert waste into energy. The interconnected nature of IoT devices allows for real-time monitoring of waste streams, optimizing collection routes, and ensuring the efficient utilization of resources. Machine Learning, on the other hand, introduces predictive analytics to enhance the efficiency of energy conversion processes, making them more adaptive and responsive to fluctuating waste compositions. This integration not only addresses the logistical challenges of waste management but also enhances the overall efficiency and sustainability of the Waste-to-Energy paradigm.
In essence, the overview of Waste-to-Energy underscores its pivotal role in the pursuit of sustainable urban development. By converting waste into a valuable energy resource, cities can mitigate the environmental impact of landfills, reduce dependency on fossil fuels, and contribute to the creation of a circular economy. In the subsequent sections, we delve into the intricate nexus of Waste-to-Energy, IoT, and ML, exploring the technological advancements, challenges, case studies, and future prospects that collectively shape the landscape of sustainable power generation in the context of Smart Cities.
