Contractor teams entered the WtE plant in Warsaw (ZUSOK) for its modernization and expansion in April 2021. After two years, the plant is completely transformed. Of the old buildings, only the remnants of the green halls (on the left), used as a temporary waste storage facility, and the No. 1 line boiler hall (the building with white and green stripes on the right of the new chimney) can be seen in the photo. All other buildings were built in 2021 – 2023.
