Apart from the inherent properties of the raw material (agricultural waste), the briquetting process could also have an effect on briquette quality (Ndiema et al., 2002).Briquettes from different materials or processes differ in handling and combustion behavior; briquettes from same material under different conditions can have different qualities or characteristics.

Iron: Combine low cost with good bearing qualities, widely used in automotive applications, toys, farm equipment, and machine tools. Powdered-iron is frequently blended with up to 10% copper for improved strength. These materials have a relatively low limiting value of PV (on the V side), but have high oil-volume capacity because of high porosity.
