Domestic wood combustion

Bio mass combustion in boilers, fireplaces, stoves and other furnaces is a major source of fine dust that is particularly small in size; typically < 1 µm.  In Finland, for instance, more than 40% of the total fine particulate matter emission comes from domestic bio mass combustion. The second biggest polluters are the power and centralized heating plants with 23% of fine particulate matter, after which comes road traffic accounting for roughly 15% of the total pollution. 

Also the amount of Black Carbon, that is known to increase clobal warming is reduced with Tassu's EDF tercnology.  Bewlow is a quote from Stanford University/Jacobson study.

Jacobson explained that black and brown carbon particles can boost warming in three ways. First, they enter the water droplets that form clouds, where they bathe in sunshine and absorb the light energy. The particles in turn create heat, and the water droplets evaporate at a faster pace. A second way is that carbon particles can float around in the spaces between water droplets, similarly absorbing sunlight and converting it to heat.

Clouds dissipate as a result, and the natural shield they provide between the sun and the planet disappears, so that more sunlight reaches the ground and oceans -- and thus warms land and air temperatures.

Third, biomass-related carbon particles can settle on snow and ice, absorbing the sunlight and causing the frigid surfaces to melt at accelerated rates, exposing dark soil and dark seas. These, too, absorb even more energy from the sun, amplifying the rate of warming.

Tassu provides patented EDF (electric diffusion filter) for domestic bio mass combustion. EDF is a low-cost and low-maintenance solution for households and centralized heating.
