Energy-from-Waste (EfW or waste-to-energy) facilities offer a safe, technologically advanced means of waste disposal while also generating clean, renewable energy, reducing greenhouse gas emissions and supporting recycling through the recovery of metals. According to a 2012 whitepaper released by Solid Waste Association of North America (SWANA), energy-from-waste facilities "are economically sound investments that provide multiple financial and environmental benefits to the communities that utilize them."
