The production of Scotch whisky has evolved over more than 500 years and is steeped in tradition. Family-run, centuries-old distilleries are trying to minimize operational costs. Most distilleries in Scotland have relied on heavy fuel oil to generate heat for distilling processes, but biomass such as wood, plant-based material or organic waste is now an increasingly attractive and reliable option.
