Municipal Solid Waste Incineration: Optimizing Design for Large-scale Waste Management

Introduction

Municipal solid waste incineration (MSW incineration) plays a pivotal role in large-scale waste management strategies. It offers a sustainable and cost-effective solution to dispose of non-recyclable waste and generate energy. However, optimizing the design of MSW incineration plants is crucial to ensure efficient and environmentally responsible waste management.
