Conducting industrial research and development work at SZPEC Piotr Szwajkowski, enabling the development of a unique recipe related to the quality of light artificial aggregates obtained using fine granite waste and the disposal of municipal sewage sludge.
Reference number of the aid programme: SA.41471(2015/X) Purpose of public aid: Article 25 of EC Regulation No 651/2014 of 17 June 2014 declaring certain types of aid compatible with the internal market in the application of Articles 107 and 108 of the Treaty (OJ L. I'm sorry. EU L 187/1 of 26.06.2014). Under this project, research is planned to develop a unique recipe related to the quality of lightweight aggregates obtained using fine granite waste and the disposal of municipal sewage sludge, in order to offer it to its customers in the form of a licence. The aim of the project is to solve the problem of the development of a huge amount of fine granite waste that has arisen during production processes of granite stone processing in the masonry &ndash; it’s called granite abrasive. The formula will allow the use of this waste in the production process. Important is the planned large development (up to 60 %) of the recycled municipal sewage sludge in the composition of light artificial aggregate recipes. The final product resulting from research will be innovative internationally. In terms of product innovation, it is planned primarily to achieve higher mechanical strength compared to other lightweight aggregates (which, with the above aggregates used for the production of concrete construction prefabricated prefabricated materials, allows to obtain a higher strength class of these products) and to achieve a higher thermal insulation coefficient. The objectives of the project will be achieved by carrying out industrial research (stage I and II) and development work (stage III).
