<p>PURPOSE: A BMC upper board manufacturing method recycling waste dust of acryl artificial marbles is provided to secure the productivity, the water resistance, and the air tightness of a product. CONSTITUTION: A BMC upper board manufacturing method recycling waste dust of acryl artificial marbles is as follows. Waste dust of acryl artificial marbles is crushed and mixed with unsaturated polyester resin, inorganic filler, hardening agent, pigment, glass fiber, and releasing agent by using a kneader. The mixture material is formed into a BMC upper board by pressing.
