Challenges for sludge and wastewater treatment discussed
The fact that it is cheaper to buy nutrients instead of extracting them from the sludge is one clearly identified bottleneck for introducing a sustainable wastewater treatment process. That was the general opinion of the audience of the conference Sludge and Wastewater Treatment for the Future, held in Gdansk on the 23-24th of September.
Legislation was also pinpointed as a bottleneck. Legislation often causes different obstacles and can be hard for municipalities to comply with when trying to create sustainable and economically viable solutions.
The conference in Gdansk was the second conference in a series of events within the EU co-financed project Euroslam. The participants were given presentations on how the current situation for wastewater treatment plants in Poland, Lithuania and Sweden is, but also how municipalities have chosen to work with the sludge problem, based on national legislation and local conditions.
