A loan helped to buy a biodigester to cook with biogas and help the environment.


Carolyne's story

Carolyne plans to use a Sistema Biobolsa biodigester to eliminate wood, fossil fuels, and chemical fertilizers from her farm. She lives in Kiambu with 5 family members, including parents. She supports her family with income from her 15 cows and from her annual vegetable yield.

Carolyne wastes time chopping wood to burn for cooking and heating bathwater, and also worries about the air quality for her family. With the biodigester, she will transform cow manure into renewable energy (biogas) and organic fertilizer. As she starts putting the animal waste into the biodigester, bacteria will convert it into both biogas for cooking and nutrient-rich fertilizer that Carolyne will apply on her vegetable field. All of this will enable her to increase her yield, eliminate the need to chop wood, and use the money she used to spend on fossil fuels and chemical fertilizer to invest in additional cows.

With this Kiva loan, Carolyne will realize her dream of making her farm economically and environmentally sustainable in order to continue the generations-old tradition of farming in Kiambu.

This loan represents 63% of the full price of the biodigester; the remainder was covered by a cash down payment and a government subsidy.


This loan is special because:

It saves farmers money by transforming waste into biogas and organic fertilizer.
