Work at ZUSOK in Warsaw is intensive, and due to the nature of the project – the expansion and modernisation of the existing active plant – the particular facilities are growing in line with the availability of the work front and logistical capabilities. While the slag processing halls are still in the final stages of foundation and wall work, there are also buildings where the roofs have already been constructed. It is worth remembering that the roofs at ZUSOK will be green, thus ensuring water retention and better conditions for the local ecosystem. The greening of the roofs will reach an area of 20,000 m2.
