The KVA Hagenholz in Zurich is the City of Zurich’s waste-to-energy plant, operated by Entsorgung + Recycling Zürich (ERZ); since the closure of the Josefstrasse plant in 2021 it is the city’s only incineration site. Its two lines treat around 250,000 tonnes of waste per year and provide a large share of the heat for Zurich’s district heating network, achieving the highest net energy efficiency of all Swiss plants in the national benchmark. A third line built by Hitachi Zosen Inova (Kanadevia Inova) will raise capacity to 360,000 t/a.
