Abstract:
Lowland municipalities of Lombardy region are interested by air quality problems related to PM10 and NO2. The households in the area are connected to the natural gas grid but biomass is still used as an alternative for heating. Residential biomass combustion emissions amount to 3,408 t/y for PM10 and 600 t/y for NOx. Most of PM10 emissions (95%) are attributed to wood log-fed appliances. Although pellet appliances account for 33% of the total number of appliances in the study area, their contribution to PM10 emissions is only 5%. The replacement of all biomass heating appliances with high-environmental-performance pellet appliances would lower the primary PM10 emissions by 90% but would not have a significant effect on NOx emissions. If an overall turnover scheme were implemented the cost of avoiding 1 kg of PM10 emission would be €23. State incentives that potentially may facilitate this turnover exist but at the present result to be underutilized. Given the residual amount of PM emissions and a very limited mitigation of NOx emissions, decarbonization efforts for residential heating based on biomass heating, where possible, should be oriented towards biomass combustion in larger more controlled plants where emission abatement is possible (e.g., district heating)
