Recycling of critical raw materials for the economy, is of great importance from the perspective of both environmental protection and sustainable economic development. It takes into account the needs of present and future generations by allowing valuable materials to be used instead of extracting new key fossil raw materials. In the recycling processes used, individual fractions of raw materials and metals are recovered, ultimately leading to granulates that are pure feedstock for smelters and manufacturing companies that process them into a finished commercial product for use in a wide range of industries.
