Project Background

Before installation, Green Pastures relied on diesel generators to run milking machines and chillers—costly, unreliable, and carbon-intensive. With rising fuel costs and local climate pressures, the farm needed a renewable solution to support its dairy operations.

Challenges & Innovations

The high elevation of Eldoret meant cooler nights, which can slow digestion. We added thermal insulation and used slurry pre-warming to maintain optimal temperatures and microbial activity.

Conclusion

Biogas is more than a renewable energy solution—it’s a practical, cost-effective tool that empowers farmers to do more with what they already have. From reducing fuel expenses to improving soil health and creating new revenue streams, the impact is clear. As more small farms adopt this technology, the agricultural landscape in Africa is being reshaped—cleaner, more resilient, and future-ready.
