The end product is put in the cement plant. In the pre-calciner (an element of the cement plant that optimize fuel consumption) the resin matrix is used as an alternative fuel, substituting coal, petroleum coke, heavy fuel oil or natural gas. At a temperature around 900 °C the resin burn transforming the blade fibers into ashes.

The quality of cement is measured by the surface area or the Blaine index. The unit of the Blaine index is m2/kg, and this index is determined by the Blaine air permeability test. The surface area of the cement powder depends on size distribution of cement particles; smaller particles have larger surface area.

In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1.
