[en] There are significant economic and environmental interests to transport the sludge, which comes from the sewage treatment plants, to the incinerators by inland waterways. Due to the physical and chemical characteristics of the sludge, conventional means of waterway transport meet with the limits and the new technologies should be introduced, especially in the aspects of sludge holding and handling. This paper will introduce briefly the study made for the local communities in the region Walloon (Belgium) to establish such systems of sludge transport by inland waterways. The study covered the handling and holding techniques, the optimal shipping operations, and the socio-economic benefits assessments.
