For several years, NRC has been looking for new ways to constantly improve the purification of the residual stream of bottom ash, the bottom ash minerals, for one of its clients. NRC has continuously invested in additions to the basic configuration of a separation plant in order to optimise every fraction of the bottom ash mineral for reuse. Examples are additional modules for deferrisation, wind shifting and the removal of irregular fractions by means of sensor separation. Years of expertise in processing bottom ash and the ability to supply custom-made products result in optimal products for our customers.
