Human waste to biogas, enabling schools with a reliable, convenient, and affordable source of energy

The Problem

Kenyans face two large obstacles, access to proper sanitation and cost affordable, sustainable energy sources

According to the Kenyan Ministry of Education, over 50% of schools in Kenya lack proper sanitation facilities, with an estimated 31,000+ primary schools in rural Kenya alone. Improper waste disposal, including human waste, contaminates local water sources and contributes to the spread of diseases Source: World Health Organization, posing significant health risks to students and staff.

Additionally, 70% of Kenyan schools lack access to clean and affordable energy sources for cooking.

Without reliable sources of energy, schools often resort to using firewood for cooking, contributing significantly to deforestation and climate change Source: CIFOR This reliance strains school budgets and creates a toxic environment in kitchens. It's crucial these issues are addressed to improve health, education, and environmental sustainability in the future.

Mobile Alert Toilets biogas reactors

Our Solution

  • Mobile Alert Toilets (MAT) constructs affordable pour-flush latrines using recycled materials or modify existing latrines into pour-flush systems
  • We channel waste from the latrines to our biogas reactors, adding food waste from the school kitchens. The waste then undergoes biological reactions to generate methane gas.
  • This methane gas is captured and used for cooking in the school kitchens, replacing firewood. We also install a smart meter to monitor system health for optimisation.
  • The remaining effluent, known as digestate, is collected, further treated and can be used for watering gardens and hedges within the school premises.
