Abstract: The current invention concerns a method for preparing a coated particulate waste material, comprising the steps of: (a) providing a particulate waste material with an average particle size of between 0.1 and 5.0 mm, and (b) applying a coating material to said particulate waste material, whereby said coating material comprises at least one polymeric compound. In a second aspect the present invention discloses a coated waste particle comprising a waste material core, and a coating surrounding said waste material core, whereby said waste material core has a particle size of between 0.1 and 5.0 mm and said coating comprises at least one polymeric compound. A further aspect concerns a building material, comprising one or more coated waste particles.
