In this category many residual materials are present, for example calcium and wood. The fraction present can range from 5 to 50%. At 5% > 25% of the same material one can speak of a weak presence of the material. At 25%>50% of the same material one can speak of a strong presence of the material. Organic components are not accounted in the tertiary category. For other materials present the samples need to be of at least class QM4. Further below some components are explained.
