Did you know that your daily poo can be used as a household fuel that you can even use to roast your favorite meat?

The poo briquettes being made and processed by the Water and Sanitation Services Company (NAWASSCO) Nakuru,Naivasha and Nairobi is being used a method of environmental consecration and also as energy.

The method of collection of poo has also improved sanitation in towns and villages because there are some chemicals used to carbonize and reduce the smell from the poo thus making it easy to collect.

Water and Sanitation Chief Administrative Secretary Winnie Guchu said this is the best way to conserve the forest that are under threat and manage sanitation.

“This method will also see many youths get employment at the ministry because they can be able to help in collection of the poo from latrines and also selling the briquettes,” said Guchu.

She is encouraging more innovators to come up with more technical methods of environmental conservation and sewage managements within the city.

According to her the challenge of sewage management is not only at the City Slums but also in apartments where there is need for proper methods of sewage managements.

Lydia Macharia says her life has changed ever since she started using the Charcoal Briquetts from human waste as compared to the time she was using the once from the tree.

“I use only 15 balls to cook my meal for 2 hours, I have never seen that kind of energy for decades that only 2 kilograms can cook for over five meals,” said Lydia.

She said that she got to know of the briquettes after her friend a Personal Assistant to Winnie Guchu brought her 2kg to go and try it at home.

Lydia used only three quarter of the balls and the results were overwhelming, she says that the balls do not have any smell though she has not tried it inside the kitchen.

“I am yet to use the briquettes inside the kitchen and find out whether indeed the balls will produce any smell because some people are having a perception that they could be smelling,” said Lydia.

She said that she only noticed minimal smell from her medium sized Jiko while using the briquettes and also there was not smoke at all.

According to her, she do not plan to go back to using the renowned charcoal from the trees because this is also a method of environmental conservation.

She wants Kenyans to know the importance of forest conservation because we have witnessed many cases of drought and the use of waste briquettes is the way to go.

Lydia has since purchased 25 kilograms of the briquettes from NAWASCO Nakuru and 2 more Kilograms from NAWASCO Naivasha.

She is encouraging her friends and family members to try this balls as a way of cooking because they can be able to cost save more than a double of the old charcoals.

“I am encouraging the youths to make use of the opportunities created by the Ministry of Water and Sanitation to join in the process of collection of human waste as a method of environmental conservation,” said Lydia

Lydia tell the youths can be hired at NAWASCO Ruiru where they can also get some small briquettes for to sell.

Naivasha companies are using a lot of So-dust and might lead to more people having to cut the trees which is not an environmental conservation at all.

Those people who have used the briquettes say it is cheaper and cost effective that charcoal because 2kg is Sh 60 compared to the normal charcoal that goes for over Sh 120 per 2kg.


The human waste are collected from pit latrines and septic tanks around the region of Nakuru, North West of Nairobi.

The waste is then taken to a processing plant, where it is dried out for two to three weeks in drying beds in a greenhouse.

The hot temperatures in the greenhouse take out around 70 per cent of moisture from the sludge, which prepares it for carbonation.

The dried waste is then heated in a kiln at temperatures of about 700 to 800 degrees Celsius, which burns off harmful gases (and the smell).

It’s ground up finely, before being mixed with sawdust that has also been carbonized.

Molasses are also added at this stage to bind the materials, and it is formed into little balls.

The combined materials of milled sawdust and sludge are fed into a rotating drum machine, while molasses (a binding agent) are added gradually until the mixture forms a ball of about 2.5 cm in diameter.

Human excrement are being carbonized to produce balls used as charcoal for fire.
