Its main goal is to develop solutions, technologies and guidelines to optimise waste management in a mining company, oriented according to the circular economy principles to maximise the use of waste materials. The project leader is the Central Mining Institute - National Research Institute (GIG-PIB), and the industrial partner is the Polish Mining Group (PGG). Sustainable management of basic mine waste is a key element in the economic efficiency of mining plants. The management of ‘rock’ from processing plants and the capture and management of coal mine methane are, next to underground water disposal, the most capital-intensive areas of waste management in European mines.
