  Collection of sample is first step in estimating the composition of solid waste.

  1. Frequency and timing of samples collection should be carefully.
  2. Sample collection should extent over a full work in each season.
  3. It is important to note that the large the no. of samples more representative are the result.

  3. Divide into 4 blocks
  4. Remove two blocks of waste diagonally opposite end.
  5. Mix and latten remaining waste.
  6. Divide into 4 block again.
  7. Reduce the waste volume by same process.


          Hence the method of solid waste sampling was studied.
