The Sanergy Model


The Sanergy Model

We take a systems-based approach to solve the sanitation crisis sustainably.

Sanergy 3 step


We design and manufacture low-cost, high-quality sanitation facilities. Developed by our engineers, the Fresh Life Toilet is pre-fabricated at our local workshop. Our FLT features qualities users value most:

  • Hygiene: FLTs are made of high-quality materials that are easy to keep clean and maintain.
  • Accessibility: FLTs have a small footprint that enables us to install them close to homes
  • Affordability: FLTs are cost-effective and include essential features like hand-washing facilities.

Through informal settlements, we build a network of Fresh Life Operators – local residents who purchase and operate our hygienic sanitation facilities. The operators become franchise partners: we provide our FLT, training, access to financing, ongoing operational and marketing support, and a daily waste collection service.  The FLO generates local demand and ensures that the FLT is kept clean. We have three distribution models for our Fresh Life Toilets in the communities:

  • Commercial: Pay-per-use toilets run by local entrepreneurs
  • Residential: Toilets in residential plots, offering tenants secure 24-hour access to hygienic sanitation
  • Community Institution: Toilets in schools, churches, and clinics to reach the most vulnerable populations

We collect the waste on a daily basis. Our Fresh Life Frontline is trained and properly equipped to remove the filled cartridges and replace them with clean empty cartridges. The waste is safely removed from the community by wheelbarrow, handcarts, and/or truck. The wheelbarrows and handcarts ensure that we can install FLTs deep in informal settlements where there are only narrow, unpaved roads as access points.


We convert the waste at a centralized facility into useful end-products such as organic fertilizer, insect-based animal feed, and renewable energy. To produce the fertilizer, we co-compost the waste with sawdust, other carbon sources and effective micro-organisms, which eliminates pathogens. Then, we let the compost mature in windrows. Once ready, we test every batch of fertilizer by third parties to ensure compliance with World Health Organization standards.

To produce the insect-based animal feed, we have a colony of Black Solider Flies, whose larvae consume organic waste, removing the pathogens and converting the waste into protein. Boiled and sun-dried to eliminate any pathogens, the larvae make a sustainably produced, nutrient-rich protein input for animal feed. We also find ways to re-use the urine and capture the biogas released by the waste. 100% of the waste is safely treated.


In East Africa, there is high demand for our products. 1.2 million tons of synthetic fertilizer is imported every year, leading to high transportation and tariff costs, which is ultimately borne by farmers. In fact the price of fertilizer is so high that farmers can only afford to purchase 9 kg/hectare of fertilizer compared to the 206 kg/hectare used in the industrialized world.We sell organic fertilizer to a variety of Kenyan farms.

Most animal feed in East Africa is made with Omena, or fishmeal, as its main source of animal protein. Harvested from Lake Victoria, Omena is not sustainable and is delivered to feed millers mixed in with a lot of other materials, including sand, shells, and other fish.The low quality of Omena results in poor animal growth. Our protein input provides a consistent quality alternative to Omena.
