Background Poland produces more than 1.1 million tonnes/yr of municipal and industrial sewage sludge. Most of this is either sent to landfill, or used for composting or fertilisation of soil. A lack of incinerators means that the combustion of sewage sludge is not a feasible method of disposal in Poland. Therefore, it is important to examine other sewage disposal technologies. The beneficiary has already developed a new method of disposal of sewage sludge that uses a variety of wastes and neutralises them in a single process to produce various lightweight aggregates (which are used in construction). Objectives The main objective of the OIM-WASTE project is to demonstrate the operation of an innovative technology for waste management of selected groups, including sewage sludge, for the production of various lightweight aggregate products. Other, important objectives are: To construct a pilot demonstration installation - to determine the technical requirements to start the full-scale production of lightweight aggregates on the basis of mineral waste and municipal sewage sludge; and To conduct an information campaign about the developed technology targeting the widest possible audience of both potential project stakeholders, as well as the general public.Expected results: The main result of the project will be the technical verification of the technology: The technology already developed and tested by the beneficiary at laboratory-scale, will now be tested at industrial-scale. The implementation of the project should also increase of public awareness about the problem of managing sewage sludge. Other expected results include: A prototype demonstration installation; and Various dissemination material and activities – including participation at three trade events, the organisation of information and demonstration meetings and the publication of 500 leaflets and 250 brochures.
