Waste materials can directly be combusted for the generation of energy as fuel or other method, indirect combustion can also be adopted for energy generation. Thermal treatment for recycling purpose included burning of waste for the generation of energy used for household purpose i.e. cooking and heating while the energy from recycling can also be produced at industrial level from boilers. Among thermal treatments there are two related kinds i.e. Pyrolysis and Gasification. In these sorts of methods, materials are heated with little supply of oxygen at high temperature. This process is conducted in sealed vessels with high pressure. In Pyrolysis, the solid is converted in to liquid state and liquid is converted into gas. These products of treatment can then be used for the production of energy. The residue that is left behind is generally known as “char”, which is further treated for the production of more useable products. In Gasification however, the material to be treated is directly converted in to SynGas (synthetic gas) which has hydrogen and carbon dioxide as its components.
