In 2003 Eco-Valley became one of the first waste-to-energy facilities in the world to utilize Plasma Gasification technology on a commercial basis. Eco-Valley is located in Japan and has been successfully processing MSW with plasma for over seven years. The facility processes up to 220 tonnes-per day of MSW or up to 165 tonnes per day of a 50/50 mixture of MSW and auto shredder residue. The technology used at Eco-Valley is a result of a successful collaboration between Westinghouse Plasma Corp. and Hitachi Metals. With a first of kind facility like Eco-Valley, several operational challenges had to be overcome during and after commissioning. The objective of this paper is to share these operational experiences and learnings.
