Abstract

A method of recycling building materials is described, including the steps of introducing the building material into a cement kiln or a boiler, and combusting a combustible portion of the building material as a fuel within the kiln or boiler. The noncombustible portion of the building material is incorporated into a clinker material within the kiln or used to reduce emissions form the boiler.
