Generally, almost all secondary schools offer their entrances a clean welcoming and attractive appearance but a simple visit of the school space makes it possible to realize the existence of piles of refuse whose waste typology can only be done with rested head. These piles of waste are hidden most of the time in corners of the course of establishment and especially in the backyards of the classroom. The undersides of the stairs are not spared.

Few minutes after the recreation time allow to appreciate the consciousness of the learners with regard to hygiene and sanitation. Plastic bags and various food packages are scattered throughout the course of the establishment.

For example, the presence of an abandoned well in a school in Porto Novo in Benin that served as garbage dumps and left the immediate environment in a state of unhealthiness was found in secondary establishment in the square, since only filled, students were accustomed to this dump, have difficulty in avoiding them. Also, a little dust are leading or calling to the closing of some schools or the suspension of courses in schools like Felix-Leclerc in France.

The other form of unsanitary is that which develops inside classrooms. It is not uncommon to note that the pigeonholes in the course furniture constitute micro dumps of peanut shells skins of banana and oranges various packaging such as : biscuits, candy, yogurt etc

When it comes to sweeping classrooms, sweepers do not always realize the existence of waste in traps which gives rise to unusual odors inside the classrooms .Many secondary schools in city have garbage cans in their courtyards. But few have lids. This state of affairs means that after the regular cleaning of the classrooms and the course of the establishment and the deposit of garbage in the containers, plastic bags and many other packages such as papers are dispersed again in the course by gusts of wind.

To summarize, all this non sanitation in schools can become a very big calamity in our societies and we parents ,brothers ,sisters or close relations of students have to involve and educate them to have adequate behaviors in order to keep clean their classrooms and schools environment. We must also motivate them to join environmental organizations and programs as Tunza Eco generation. We must also sensitize teachers who use to smoke in classes and school ground to reduce or delete the smoking in these places to permit us avoiding the damages of Tobacco in children.
