**2.5 Microwave treated biomass char/apatite phosphate compost**

Washing of hazardous waste waters by microwave action efficiencies exceeding the total Fe Pb and Hg contents of sludge increased fast on coal char and wood char were also reported by Tosun [6–10]. Material to be used as powder at porous granule at ultrafine grain size, basic as absorption capacity by the gas emission and other fluids reactive and solvents. High absorption capacity having clay, only to absorb the urea not ventilated, but bad reduce smell and bacteria should avoid. The packed grain size distribution of clay granules it is important that it is usually between 1 and 6 mm is required.
