Classification of Waste:

Farming;- Garbage
Residential;-Garbage and refuse
Sewage;-Human Excreta and other sewerages.
These can be grouped under solid and liquid wastes
The solid waste is in the form of garbage and refuse while the liquid waste is human excreta. The garbage is generated mostly in the Kitchen in the form of spoiled foodstuff and excess food eaten by the Students.
The refuse is generated through the cleaning of the School compound.

Waste Disposal:

The garbage and refuse generated are dumped in a refuse Dump six(6) metres away from the school kitchen. It is a Pit dug about a meter and half deep.
The human excreta is generated in septic tanks in the school.

How we deal with waste:

The platain peel garbage is collected by a local soap manufacturing company and process for the manufacture of a local soap called ‘Alata samina’.Some people also collect the garbage to feed domestic Animals.

The human excreta and other garbages are collected by an NGO (Non-Governmental Organization) every two months for the generation of Methane gas/biogas.They mixed the collected waste with water to form a slurry. They keep the mixer in a container called a ‘digester’ where bacterias break down the waste products gas and sludge.

Another method adopted by some people is the use of landfill garbage dumps where the garbage is covered with earth. This keeps oxygen away from the garbage. The combination of water and anaerobic bacterial produces methane gas which can be collected from the dump and used.
