Waste-to-Energy plants represent a critical intersection of waste management and power generation, converting municipal solid waste into electricity and heat. These facilities require complex integration of waste processing, combustion systems, and environmental controls. Construction typically spans 24-36 months, with critical components requiring procurement initiation 18-24 months before installation.
