Positive effects of wood biomass on the economy
The production and use of forest biomass have several positive effects on the economy:
Increasing of income,Supplementary activities for farms,Supplementary employment in rural regions,Thinning contributes to the quality of stands, Decreasing of CO2 pollution.
