The use of biomass is classed as being ‘Carbon Neutral’ and therefore do not contribute to Global Warming. As trees grow, they absorb carbon dioxide from the atmosphere during photosynthesis. When the wood is subsequently burnt, that same amount of Carbon is released back into the atmosphere and thus there is no net increase in Carbon and no impact on the environment. Compare this with the burning of fossil fuels such as oil and gas where the Carbon has been locked away for millions of years — until we burn it and release it. Biomass is also a renewable energy. Trees are specifically grown to produce biomass fuel in sustainable forests that are constantly replanted as trees are felled. The fuel can be grown in many parts of the world and thus we are not dependant on the traditional fossil fuel sources. Waste wood from sawmills and manufacturers which may otherwise end up as landfill can also be used for the production of wood pellets.
