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 mm.sup.3 to 15 cm.sup.3 by 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
