Every year billions tones of waste are generated worldwide. With an increase in population, urbanization and technology advancement, the amount and type of waste is rapidly increased, causing negative impacts on health and the environment.

as a moist solid product from waste water treament facilities
Increased costs of using of fossil fuels and environmental aspects become as the driving forces in search for alternative methods of waste treatment. Transformation of waste treatment: from landfill disposal to controlled combustion in incinerator and eventually to environmental friendly and efficient pyrolysis technology for material and energy recycling.
Advantages vs. landfilling:
Pyrolysis is a thermal decomposition of organic compounds during heating in th eabsence of extrenal oxygen(air) supply
Generated pyrolysis gas can be further used either as source of thermal and electrical energy or, in some cases, for pyrolysis oil recovery.
deliver effective initail waste volume reduction, materials and energy recovery from pyrolysis process, less gas emissions comparing with incinerator, stable operation for a broad range of wastes, no fuel supply for normal operations
One of the major sources of air pollutions are coal fired power plants which emit particles, carbon and sulphur dioxide, nitrogen oxides. Gas emissions also contain heavy metals such as mecury and cadmium. Large quantities of water are often needed to remove impurities from coal in the process is known as coal washing. Quite often coal power stations are located in the vicinity of cities worsening environmental situation in populated areas.
