Caloric value of waste stream



Chuck,

I did some research into fiber reinforced plastics recycling in 2004.  I looked back through some of the journal articles I reviewed and I think I found some useful information.

The article states that SMC contains large amounts of inorganic material (fiberglass and CaCO3).  It lists SMC's caloric value at: 6.7 MJ/kg or 2881 BTU/lb.  This particular article also states that this value is low and that incineration is not an appropriate method for disposal.  Of course, your client's SMC may have a different ratio of resin to reinforcement and filler.

The journal is called "Fuel" and the article is titled, "Recycling by pyrolysis of thermoset composites: characteristics of the liquid and gaseous fuels obtained."  It was published in 2000, vol. 79, pages 897-902 in the journal "Fuel."  The authors were A. Torres, I de Marco, B.M. Caballero, M.F. Laresgoiti, et. al.

I hope that helps.

Would greatly appreciate any information about the caloric value (BTUs/lb) of sheet molding compound (SMC). This is a fiberglass reinforced, thermosetting polyester resin. It's used in the manufacture of auto parts, small off-road vehicles, and personal watercraft. My client wants to avoid landfilling and I thought a WtE facility might be able to use it. Thanks very much.
