Waste Management

Project Concept

The waste management project aims to introduce a sustainable waste management system for the Bignona markets, the Djiragone market in Tenghory and the Bignona bus station in the Ziguinchor region of southern Senegal. This project is being implemented as part of the Greenin Africa Tigether activities in collaboration with the Foret International association.

This project is a response to a difficult situation caused by the fact that all the waste is grouped together in one place without any separation, and this waste is a real public health concern because of the stagnant water, the presence of animals and the smell. This water infiltrates and contaminates the groundwater, which is one of the most important sources of water for the population.

The 4 main strands.

The project begins in September 2023 with training in waste sorting techniques for the Djiragone market women’s association and the Bignona market transporters’ association .

The second part consists of installing waste separation bins at specific locations in the markets and at the bus station.

The third part of the project involves setting up biogas plants to treat organic waste. This biogas will also be used to produce gas for a restaurant for the market women. It will also be used to produce liquid compost for use by farmers in the area.

The final part of the project involves setting up a unit for shredding, granulating and compacting plastic in order to manufacture objects and other derived materials.

Financial Impact in the community

At present, all the waste is dumped in one place. They make no money from it. With the project, we will be able to generate income from the sale of plastic. The biogas will also be used to run a restaurant for the women, who will be able to earn a considerable income from it. The biogas will also enable the production of compost, which will be sold and increase income.

Fundraising for the project

A. Funded through CO2 compensation: The carbon avoided by this project is estimated at 925 tons of carbon per year, the carbon reduced is 1625 tons per year and the carbon stored is 300 tons per year. The sale of these carbon credits will help generate a significant amount of money for the project.

B. Funded through donations: The project is also appealing for donations via the Betterplace website, as well as calls for donations to partners, relatives and acquaintances. We also take part in fundraising events organised at the University of Berlin.

C. Funded through income generations: Funds will also be generated from the sale of sorted plastic, part of the income from the restaurant and the sale of compost from the biogas.
