Sophisticated solution with potential for the future

The plant will be constructed over a period of two years during ongoing operations. It includes the planning and construction of the process stages thickening, digestion, gas utilisation, dewatering, drying and incineration. The sewage sludge produced at the site and co-substrates produced in the Utena catchment area will be utilised. The sewage sludge mono-incineration plant, which is designed according to the sludge2energy process, is also able to accept external sludge from other sewage treatment plant sites.

The future plant has been adapted to meet municipal requirements. It has a wastewater-free flue gas cleaning system and contributes to waste disposal security for the region.

With this plant, the WTE Group is making an important contribution to the region’s waste disposal security as well as to environmental protection through the conversion of the biogas produced into electricity and the possibility of later recovering vital phosphorus from the resulting ash.
