Direct combustion of agricultural residues and their use for the energy production in small plants, without emissions abatement systems, represents a relevant source of atmospheric pollution. Particulate matter is certainly one of the main harmful compounds generated by combustion process. PM is dangerous for humans as it is able to penetrate through the respiratory system at various depth levels depending on its aerodynamic diameter. PM is essentially composed of unburnt products, including inorganic species such as metals. Sadly, known practices in agriculture such as “open burning” allow you to quickly solve problems of encumbrance and disposal of agricultural waste, but have a significant negative impact on the human health and atmosphere. The aim of this work was to characterizes, in terms of metals emitted, PM10, PM2.5 and the fraction between 10 and 2.5 generated by a biomass combustion plant with and without multi-cyclonic filter. The results show that the abatement system significantly reduces PM emissions, especially PM10 and the fraction between 10 and 2.5.
