Using renewable energy is one of the most important problems of the world and among renewable energies, biomass is considered as the first position in supplying the global energy so that more than 10% of supplying global primary energy is provided by biomass resources. In the field of power generation from renewable sources, after water energy, biomass is in the second place which is allocated 6% of global share in 2000 and in a new step followers of renewable energy use, it is going to recycle concrete rubble by lightning and every year, thousands tons of concrete rubble are created by renovation of roads and destruction of old buildings.
