Biomass energy pollution "being overlooked"
A study by the Danish Gas Technology Centre (DGC), an industry consultancy, suggests that biomass energy is more polluting than often realised. DGC compared natural gas with wood or straw burned in small district heating boilers. It puts the overall "environmental costs" of biomass at 50-400% higher than their gas-fired equivalents. Gas burning produces CO2 and nitrogen oxides, DGC acknowledges. But biomass emissions of sulphur dioxide, VOCs, and fine particles are often overlooked, it adds. The EU is currently exploring ways to increase growth of biomass energy (EED 04/02/05). See DGC press release and report.
