—LAND FILL
—It is the most traditional method of waste disposal.
— Waste is directly dumped into disused quarries, mining voids or borrow pits.
— Disposed waste is compacted and covered with soil
— Gases generated by the decomposing waste materials are often burnt to generate power.
—  It is generally used for domestic waste.
   INCINERATION

— Incineration is a waste treatment process that involves the combustion of solid waste at 1000C.
— Waste materials are converted into ash, flue gas, and heat.
— The ash is mostly formed by the inorganic constituents of the waste and gases due to organic waste.
  The heat generated by incineration is used to generate electric power.

It also breaks up large or fragile items of waste.   2) This process is conspicuous in the feed at the back end of many garbage collection vehicles.  3) Deposit refuse at bottom of slope for best compaction and control of blowing litter.   PYROLYSIS     1)  Pyrolysis is defined as thermal degradation of waste in the   absence of air to produce char, pyrolysis oil and syngas , e.g. the conversion of wood to charcoal also it is defined as destructive distillation of waste in the absence of oxygen.       2) External source of heat is employed in this process.
