Product Description

The Sanergy Fresh Life Toilet is a urine diverting dry toilet housed within a prefabricated concrete structure. The floor has a squat plate and two holes, one for liquid waste and one for solid waste, that lead down to removable waste cartridges. Sanergy sells the toilet as part of a franchise model which includes waste collection services. The collection service transfers waste to a treatment facility where the waste is converted to energy, fertilizer, and insect protein for animal feed –  a valuable asset for farmers in East Africa.

The toilets are sold to Kenyan entrepreneurs and includes installation, painting and daily waste collection for one year. Owners of the toilets, called Fresh Life Operators (FLO), receive business management and operations training from Sanergy and can earn revenues by charging customers. Financing is available through a partnership with Kiva, an online micro-lending platform.

Waste collection service is free for one year with purchase of the Fresh Life Toilet. Waste collection is approximately $106 USD for each subsequent year.

Design Specifications

The structure has a 3' x 5' footprint and can accommodate waste from approximately 120 uses per day. Fresh Life Toilets (FLTs) are operated by Fresh Life Operators – local residents who purchase and operate the hygienic sanitation facilities. As franchise partners, the operators receive FLT, training, access to financing, ongoing operational and marketing support, and the daily waste collection service. The Sanergy Fresh Life Frontline collect the waste on a daily basis from FLTs. The 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 FLTs can be installed deep in informal settlements where there are only narrow, unpaved roads as access points. Collected waste is processed at a centralized facility into useful end-products such as organic fertilizer, insect-based animal feed, and renewable energy. To produce the fertilizer, Sanergy co-composts the waste with sawdust, other carbon sources and effective micro-organisms, which eliminates pathogens. Then, they let the compost mature in windrows. Once ready, they test every batch of fertilizer by third parties to ensure compliance with World Health Organization standards. To produce the insect-based animal feed, Sanergy uses 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. Sanergy is investigating ways to re-use the urine and capture the biogas released by the waste. 100% of the waste is safely treated.

The FLO is provided with training upon franchise purchase. Handling human waste can spread disease, waste is safely collected and removed by Sanergy employees daily.

Complementary Technical Systems

Sanergy has partnered with SweetSense a low-cost remote monitoring technology enterprise to include sensor in their toilets. The result is a network of waterless toilets in urban slums that tell Sanergy’s waste collectors how full they are. A solar powered lantern is mounted to the roof to provide light at night. A hand-washing station is included inside the Fresh Life Toilet.

Compliance with regulations

According to the website, the cartridges are removed to Sanergy's waste management center and solid waste is treated in accordance with WHO, industry, and Kenyan government standards. Fertilizer is tested by third parties to ensure compliance with World Health Organization standards. Third party testing organization and testing methods not specified.

Evaluation methods

Field trials.

    Target user(s): I would add that this solution is specifically for users in high-density population settings (e.g. urban areas, potentially refugee camps), because this particular waste collection business model would not be cost-effective otherwise.
