The determination of heavy metals can be helpful to predict potential contamination caused by combustion of the biofuel. If ashes are to be put back in the forest as fertiliser, it’s important to be aware of those elements that can be harmful to the environment. Regular checks can be useful to help identify purity of the product.
IPL can test your solid biofuel by ICP for Arsenic, Boron, Chromium, Copper, Lead and Zinc and uses its DMA to quantify Mercury to a sensitivity of 20ppt (ng/kg)
Although these test currently aren’t part of the Technical Guide for standard testing methods for solid biofuels, they help assess the quality and purity of the solid biofuel.
