Waste to Energy in Action: Case Studies of Successful Incineration Programs

Introduction

Waste incineration, a thermal treatment technology, converts waste materials into energy and non-hazardous residues. When implemented efficiently and responsibly, waste incineration can contribute to waste reduction, energy generation, and environmental protection. Case studies of successful waste incineration programs showcase the practical implementation of this technology in different regions.

Case Study 1: Singapore’s NEWater and Waste-to-Energy Plant

• Singapore’s NEWater and Waste-to-Energy Plant combines water reclamation and waste incineration.
• The incineration process generates heat and electricity, while the molten residue is treated to produce sterile ash.
• The plant has significantly reduced Singapore’s waste volume and generated renewable energy.

Case Study 2: Covanta’s Waste-to-Energy Facilities in the US

• Covanta operates multiple waste-to-energy facilities in the US.
• The incineration process generates steam, which is used to generate electricity.
• These facilities have reduced air emissions and produced valuable energy.

Case Study 3: Copenhagen’s Waste-to-Energy Plant

• Copenhagen’s waste-to-energy plant combines municipal solid waste and energy crops to generate heat and electricity.
• The plant has significantly reduced the city’s greenhouse gas emissions and increased energy self-sufficiency.

Common Elements of Successful Incineration Programs
