The calorific value of Paulownia biomass is little over 50% than the one of the coal (as with the rest of the wooden biomass species) but the lower content of pollutants such as sulfur and the fact that Paulownia is a renewable resource clearly points to its environmental benefit.
Paulownia wood has the advantage of lightness and substantially reduces the transportation costs comparative to other woods – at normal conditions it will rapidly air dry to moisture content between 10 and 15%. Open air dried the wood density generally ranges between 260-330 kg/m3 .
By correct cultivation Paulownia is definitely one of the most rapidly growing plants. Paulownia uses highly efficient photosynthesis to include carbon inside its metabolic pathways.
Within a Paulownia plantation soil carbon levels increase from the accumulation of organic matter at the time of defoliation and due to the large root system that has an important function as regards to the carbon reception. Paulownia could be cut from the same root system at least 4 - 5 times consistently improving the soil by its growth, and thus its turning it into a truly sustainable culture compared to other biomass systems.
