- - - - Residence Time
      - Turbulence
      - Temperature
    - - Source of ignition / heat
      - Oxygen / Air
      - Combustible / Incineration waste
  - - - Moisture content, volatile matter, fixed carbon, ash
    - - Use of bomb calorimeter / by calculation
    - - C,H,O,N,S, Ash, Halogens group
    - - Temperature at which ash melts and form clinker by fusion ad agglomeration
  - - - Rotary Kiln
      - Fixed Grate
      - Fluidized Bed
      - Specialized Incineration
      - Moving Grate
    - - Burn Pile
      - Burn Barrel
  - - - Air discharges can be controlled
      - Incineration can be done at generation site
      - Small disposal area required
    - - Some materials are noncombustible
      - Public disapproval
      - High capital cost
- - - - Ideal fuel source
    - - As coal replacement in certain combustion process
      - Used in agriculture for soil amendment
    - - Upgrade to a special engine fuel
      - Gasification process - syngas and bio-diesel
  - - - Wide range of biomass feedstock can be used in pyrolysis process
      - High efficiency and good environment performance characteristic
      - Can be performed at relatively small scale and at remote locations
    - - Very dependent on the moisture content of the feedstock
      - High moisture waste streams require drying before subjecting to pyrolysis
      - At higher moisture contents, high levels of water are produced
- - - - Hydrogen
      - Carbon Monoxide
      - Methane
  - - - Can be designed for a small medium scale
      - Syn-gas can be used after proper treatment to generate highly-quality fuels
      - Fuel syn-gas generated by gasification is easier to handle, meter, control and burn than solid MSW
    - - Syn-gas is toxic and potentially explosive, requires a reliable control equipment
      - the required syn-gas conditioning and cleaning is today costly
