Community meeting Bio-Centre Kiandutu Slum

Together with Slum Dwellers International and Mungaano Kenya, we are working with the community to finish the bio-centre in the Kiandutu Slum. Together with the community, we set priorities and discussed their vision of the building and facilities. After a long process, we worked together on understanding the limitations of the budget and how to invest the available money the best way so it will allow the community to generate the most income. Furthermore, the communtiy is selecting artisans to work with Quirin, and will provide procurement of the materials needed. We will start the construction on Monday, and hope to have finished the building by the end of October. The facility has a biogas digester for human waste from the toilets, solar water heating for hot showers, and a kitchen area.
In the meantime, Fieke will work with SDI on building the capacity of the community leaders and selected members to run the facility as a business, starting with governance, financial literacy, business plan, project plan, savings schemes etc.
The project has two sides to it, the technical ' physical' construction of the facility, and the social construction - meaning building capacity, empowering the community to become independent and build and govern a project together which will benefit their own community and will generate income and employment.

Busia biogas for schools

On request of AMREF Health in Kenya, we have assessed two more schools in Busia for the installation of biogas and solar water heating as part of the FINISH-INK program. The schools can gain a lot not only from the gas produced by the biogas, but also to save the highly costly emptying of the latrines each term. Furthermore, the solar water heating systems can significantly reduce the amount of firewood used to heat water for cooking in the kitchen. Both schools are boarding schools, with around a 1000 students.
We also visited the farmer where we recently constructed a biogas plant as a demonstration plant for the community, and were happy to see that the gas was produced in abundance and the farmer could now connect the stove and start cooking with the biogas!
