The company uses the builds and constructs 'separator' toilets which it sells to entrepreneurs in the slums.The Ecosan system used in the loo's deposits the waste in air- tight containers. These separate containers of urine and faeces are collected on a daily basis by a waste collector using handcarts.
These entrepreneurs then charge 5 Kenyan shillings to each user. The entrepreneur pays $100 a year to Sanergy to remove the waste that has been separated into solids and liquids-by virtue of the fact that they have to to loo's in one? The solid waste is dry compost and it is sold after 6 months for use in agriculture and gardens. The liquid waste is left in large containers for up to 3 months when the content is basically pure urea. Rich in nitrogen and phosphates. This liquid is then sold at $2 per litre to farmers who add it to their drip irrigation systems as a fertiliser.
