All activities in a technically developed society are accompanied by waste generation. The question of its removal or consequent environment friendly and economic use has been dealt with by mankind since the early 1990s. The target of a common international project worked on by the Investex Group, .a.s. companies and the Research Institute for Brown Coal, the joint-stock company, is to look for ways to use the sludge from waste water treatment plants as an alternative resource for additive agent fabrication. Suitable waste treatment sludge for the additive agent preparation applied in the combustion of lower quality fossil fuels with a higher content of sulphur is generated as waste in ammonia fabrication from the sludge produced by municipal waste water treatment plants. The procedure in the agent fabrication from waste treatment sludge, the course of the combustion tests and the results of a theoretical level of desulphurization form the content of this paper.
