Biomass is not so green?

In Sweden in general, and of course in Borås, we are producing energy (heat and electricity) by burning biomass for many years. There is almost no debates that this energy-creating process is CO2 neutral and considered as green process. However, there is a debate in the USA that it is not so green process. When we read the details, the debates is about air pollution, and says that biomass create more pollution than coal and natural gas. These types of discussions are misleading. It is matter of technology used. Yes, the cheap technologies with no cleaning of the gas create a lot of pollutions, while the advanced technologies used in Sweden for burning of biomass or wastes, are far ahead of these debates.
