Claim 0:
1. A system comprising:
a ground plate located on a production line on which a composite material board is manufactured, wherein the composite material board is a roofing coverboard manufactured at least in part using a first material and a second material from a waste stream;
a displacement-type capacitive sensor probe; and
a processor with programmed instructions to:
calibrate the displacement-type capacitive sensor probe to a predetermined dielectric constant;
determine, using the sensor probe, a capacitance of the composite material board;
determine, in the composite material board placed in between the displacement-type capacitive sensor probe and the ground plate, using the determined capacitance, an equivalent thickness of the first material of the waste stream having the predetermined dielectric constant by comparing the capacitance of the composite material board to a known capacitive response of one or more thicknesses of the first material, wherein the equivalent thickness is less than a thickness of the composite material board; and
convert the equivalent thickness of the first material into a weight percentage of the first material in the composite material board, based on the thickness of the composite material board.
