It has even been found that drying biomass prior to combustion improves quality parameters in terms of reduction of volatile hydrocarbons in sawdust [39]. However, besides dehydrating the processing residues in question, densification (especially of peel materials) may also be necessary due to the low BD and high VM [36]. Consequently, additional investment for equipment required for biomass modification would have to be considered when evaluating the use of these wastes for combustion. Nonetheless, low-cost dryers and simple briquetting machines do exist [40,41]
