The Production Process of Concrete: Concrete is constructed using cement mixed with an aggregate-- a grainy blend of materials such as stone and sand. After mixing, the concrete is poured into a mold and left to harden then use in building. The aggregates are sourced from a local body of water and crushed in a natural procedure.

Most organic materials have a caloric content of 9-16 GJ/ton cement, while the main firing of a cement kiln requires at least 18-20 GJ/ton cement. Thus, biomass would have to blend with other fuels if used in the kiln. The lower process temperatures in the precalciner allow the use of lower caloric value fuels.
