## REQUIREMENTS:

1. Soil waste
2. Oven
3. Weighing machine
4. Gloves
5. Masks

## THEORY:

The percent moisture of the MSW sample is determined by weighing 1kg of the sample into a pre weights dish and drying the sample in an oven at 165 degree c.

The percent moisture content (MC) was calculate as a percentage loss  in weight before and after drying.

Mathematically,

% moisture content = Net weight-Dry weight/wet weight *100%

= I-F/I *100%

Where, I= Initial weight of waste

F= Final weight of waste

## PROCEDURE:

First of all, the municipal waste was taken, Then waste was weighted at the appropriate weighing machine. The wet weight weigned were kept in the oven for 70degree c. It was left for 24 hours for drying. After 24 hrs the dry waste were weighed in the appropriate weight machine.

## CALCULATION:

Initial weight of the waste (I)=300gm

Final weight of the waste (F) = 57gm

Now,

Moisture content (Y) = I-F/I *100%

=300-57/300 *100%

= 81 %

## RESULT AND DISCUSSION:

The initial weight / wet of waste was found 300gm. The final weight / dry weight of the waste was found to be 57gm.

Finally, the moisture content was found to be 81. The moisture content of the given municipal waste residential waste was  found very high amount of organic waste present.

## CONCLUSION:

Hence, from the above experiment we can conclude that the moisture content of the municipal solid waste was measured.
