A process for recycling of powder coating waste comprising the steps of (1) compressing powder coating waste to powder coating compacts having a volume of 0.5 mmto 15 cmby applying pressing forces; (2) placing the formed powder coating compacts into a vessel, rotating the vessel about a rotational axis inclined at an angle of 20 to 70 degrees relative to the horizontal and (3) heating the powder coating compacts while being moved in the rotating vessel until through-glassed powder coating bodies are formed.

Process for recycling powder coating waste

A process for the recycling of polymeric powder coating waste involves the steps of contacting polymeric powder coating chips with the powder coating waste to form a combination, by applying the powder coating waste to at least a portion of the surface of the powder coating chips, followed by heating the combination to a temperature and for a period of time sufficient to firmly bond the powder coating waste to the powder coating chips.
