A recent study published in the journal Renewable Energy demonstrated, for the first time, that U.S. woody biomass plants emit on average an amount of pollution almost 3 times higher to that released by traditional fossil fuel plants, such as oil and coal.According to the research, In particular, the combustion of wood pellets for energy purposes emits a wide range of air pollutants, including particulate matter and dioxins which are highly harmful to human health.Thousands of tons of toxic air pollutants, from nitrogen oxide to volatile organic compounds, would also be emitted in the pellet production process, especially in the southeastern USA.Overall, at least 55 pollutants exceeded the concentration threshold allowed by state air quality agencies by two times.The higher values - the study then highlighted - have a negative impact mostly on poor and minority communities who typically live near pellet plants. In the United States, therefore, the combustion of forest bio...
