PRISMA stands for Promoting Integrated Sediment Management.

The project is funded by the INTERREG IVA 2 Seas Programme to support a series of activities for the development of sustainable dredging techniques, treatment and disposal. The project involves Belgian, Dutch, English and French partners.

For the 2 seas programme region in general and the four countries in particular the main focus is to develop and test adapted sediment methods to improve the dredging process. Treatment on the spot, minimizing the transport distance and adapted sediment machinery are steps in the sediment process that can reduce the impact for ecological valuable areas. Dewatering of the dredge spoil means is also an important sustainable element in this process because the transport becomes much more efficient and that the processing and reuse are simplified.

Other relevant aspects are: processing capacity, quality, costs and nuisance for people living in the area. Furthermore how can treatment techniques and methods be improved so as to lessen the dredge spoil that needs to be dumped, how can the quantity of polluted material that is not suitable for reuse be limited as much as possible and how can the possibilities of reuse, both quantitatively and qualitatively, be increased as much as possible through a follow-up treatment. A final important issue will be the reuse of dredge spoil. After the dredge spoil has been taken out of the water, drained, characterized and treated, it can either be reused immediately or it will have to undergo further  treatment. The potential possibilities of reuse are countless, but strongly depend on the quality (environmental and constructional) of the dredge spoil, the degree of pollution, the effectiveness of treatment methods and the nature and manner of reuse.
