In a milestone achievement for green public infrastructure, Embu Women’s Prison has fully eliminated its use of firewood, replacing it with clean-burning biogas. In addition, the institution has swapped out kerosene lanterns for biogas lamps, improving air quality, lighting reliability, and environmental sustainability.
The prison’s sanitation approach has also undergone a revolution. Previously, septic tanks had to be emptied regularly using costly exhausters. Now, the organic and human waste is diverted into biogas digesters, producing both:
- Clean renewable energy, and
- Odourless bio-slurry, a nutrient-rich byproduct ideal for agriculture.
This is more than just a green shift; it’s a circular economy model for institutional sustainability. It reflects a new era where correctional facilities can lead by example in climate action and resource efficiency.
Embu Women’s Prison stands as a replicable model for similar institutions across Africa, proving that sustainability is not a luxury but a necessity.
