Sludge Technological Ecological Progress

Sludge Technological Ecological Progress (Acronym STEP) – increasing the quality and reuse of sewage sludge is a collaborative project funded from the Interreg South Baltic Programme. The project involves 5 entities from 4 Member States countries (PL, DK, LT, SE). The partners represent academic/research sector (universities) and practitioners managing and operating the wastewater treatment plants (WWTPs and municipality). The main aim of the STEP project is to develop tools and decisions to increase the quality of sewage sludge that can be reused for wastewater treatment plants (WWTP) of small and medium size. Small wastewater treatment plants in the South Baltic area are facing problem with sewage sludge reuse efficiency. The existing tools are mostly developed for big WWTP. The successful implementation of the project will provide a new dimension for the quality of sewage sludge.
