Mahoua: my beloved father, who taught me to do what I could...
Kàttan: energy, power, the ability to do something...
from a little girl to ...


One of Mahoua Kàttan's objectives is to create a thermo solar power station at the Senegalese towns of Darou Mousty and Touba (or in any other region according to the local needs), in order to generate electricity without polluting these regions.

Why use thermo solar power plants?


The number of hours of sunshine per day in the region is quite sufficient, even during the rain season.


Opposite to photovoltaïc solar systems who directly produce electricity, thermodynamic solar systems generate heat. The heated fluids have a certain thermic inertness (capacity to store heat) which makes the thermodynamic power production less "jerky" then the photovoltaïc production. Moreover, systems using dynamic heat storage can easily be integrated with different systems, enabling power production until several hours after sun rays have disappeared.

These centrales do not directly produce waste nor any greenhouse gas.
Also the production of the materials required to build this kind of power system is less polluting than the production of solar panels.


Meanwhile, this electricity could contribute to the creation of an artificial lake to collect rain water and reduce the consequences of the floodings during the rain season. Later, this water could be used to irrigate agriculture fields during the dry season. To be researched which (combination of) means would be most efficient in terms of implementation and maintenance costs and productivity: gutters, artificial lakes, pumps, ...

Less floodings in the towns will reduce the health risks and the power failures and boost the local economic activities, and increase the cleanness (this combined with reduction of plastic bags and sorting waste).

Plenty of projects to be defined

The sight offered today by Dakar ...


... and other towns in Senegal is not a pretty one. Heaps of filth, heaps of rubble, plastic bags, household garbage are the scenery in most places ... in spite of the government's efforts to offer an adequate and healthy living space to the people.

I was shocked by the number of plastic bags and bottles littering the streets and the beaches. It wasn't like this 20 years ago. We used to go to the market place with a calabash or a bucket.

To improve waste handling, people should sort their garbage and separate for example vegetable leftovers from (bio)chemical waste.
The current lack of regular wastebaskets doesn't make it any easier to create a clean living space.

Down with plastic bags, long live ...

Those bags that you use only once, for about half an hour, fill the streets, along the roads, the beaches, ... (see wikipedia).

By using a better recipient to transport your shoppings, plastic waste could be reduced by upto 2kg per year per inhabitant. For Senegal only that would mean 12.000 tons less waste, say a queue of several hundreds of large trucks.

Get hold of a reusable recipient and refuse the plastic bags presented at the counter that end up like this:


The alternatives

To assist you while learning the right civic actions related to cleanliness and waste sorting, Mahoua Kàttan will accompany you with


Teach the children how to sort waste! Start by optimizing the sorting at school! Those are the challenges for a solid and lasting implementation.

All schools in Senegal will be invited to participate to the activities thru which all actors will be implied as much as possible.

What we offer is a guidance in optimal waste management:

Inhabitants and organisations

How can we improve the cleanliness of public spaces?
How does waste sorting contribute to this objective? How to get started?


Today, almost all shopkeepers distribute plastic bags, and there is no sensitizing at their level. There are no trash bins allowing to sort in place in the streets of Dakar (nor in any other town in Senegal).

Our initiative is to help you find a way to reduce the use of plastic bags.

Let's act now before it's too late
