Secondary fuel can be a very inhomogeneous sample, containing all types of polymers, paper, wood and low fractions of metal. Also recycled wood or parts of automobile tires might be used as secondary fuel. Before using it as fuel in the production of cement, several chemical analyses are necessary as quality control.
