Blue Box (Sanivation)



Country:
Kenya
Why to choose this solution?
Sanivation collects human waste from special toilets and turns it into sustainable fuel, which improves sanitation and reduces the environmental impact of burning wood. It creates fuel briquettes for cook stoves, which comes from its toilet service in Naivasha (Kenya). The briquettes are cheaper, cleaner and long lasting than charcoal.
Savings per day or production:
Sanivation briquettes burn 1 hour 45 minutes longer than charcoal, thus they are more economical to use. They reduce the demand for charcoal and wood for cooking and heating, as well as help to protect the environment.
Cost in money and in own time to construct:
Installation of the blue box is free but the users pay a basic monthly service fee of KES 200 (USD 2) for the human waste to be collected twice a week. Installation takes one day.
Lifetime:
Not specified
Maintenance needed:
The blue box condition is inspected during the collection of human wastes twice a week.
Resources needed in use:
Efficient Cookstoves
Problems and limits:
The initial monthly household service fee was set at KES 600 (USD 6) which proved very expensive for the users. It was then reduced to the present KES 200, which made a big difference in uptake.The initial plan was to use flower waste, in addition to charcoal dust, from nearby flower farms. However, the cost of carbonizing flower waste was found to be too high and so the focus shifted to charcoal dust which is readily available. Production may at times be affected by fluctuations in grid electricity from Kenya power.

Climate effect (if any):
People who replace charcoal with briquettes reduce their emissions by not burning charcoal. The briquettes save about 50% of emissions, which is about 2 tons CO2-equivalent/year if saving is 2.5 kg wood/day, given the high rate of tree loss in the area. Every ton of charcoal sold saves about 88 trees.
Where it is used and how many users are there?
They are used in Nakuru, Nairobi and Narok counties. More than 1,500 tonnes of briquettes have been sold so far to factories, schools, restaurants and households. The plant has capacity to serve 10,000 people and produce 350 tons of fuel per month.
Why is it successful?
Successful because it is affordable, offers reliable, user-focused, and vertically integrated sanitation services. Studies conducted by Sanivation show a reduction in the number of people suffering from diseases related to improper human waste disposal.
