Our solution

Waffco is a simple, closed biomass burning stove for households and improved to replace open-fire stoves. The stove offers the potential not only to meet the local cooking needs in poor countries but also the environmental requirements for a better and healthy living conditions due to its enhanced fire system through its simple corridor above the combustion chamber. It serves as a free cooking technology since it is fired with generated agriculture and domestic biogenic waste and packaging waste

What's the business opportunity for host and refugee community

Many stoves can be installed by the community in the refugee camp. People can throw their dry waste (such as nuts shell, coconuts shell, bananas and corn leaves, paper and newspapers, wood cuts or any other semi-dry biogenic material) anytime inside the firing room. The humid rest of domestic biogenic waste or the rest of cultivation crops or food industry should be dried before burning it. People will be encouraged to collect their own waste since they will get heat and sterilized water.

How has it been implemented and what impact it had

The stove is so simply constructed that the complete stove can be locally manufactured by the available human power. The materials, from which the stove is made such as burnt clay and high temperature resistant metal, are all on-hand. It ensures the safe cooking atmosphere for which all emissions values are complying with german and european regulations. Many stoves are already produced in Uganda, Ghana and Mexico. Others are already donated to Accra /Ghana for non-Commercial purposes.

Our Skills and Experience

We already developed many stoves, through which a drastical reduction of indoor and outdoor pollution can be achieved to replace open fired and to imitate cooking habits in many countries in Africa. This stove owned the Siemens community Prize in 2016 and is already produced in Uganda, Ghana and Mexico. We do not aim to obtain any economic profitabilty from introducing this system. However, we seek to secure better living conditions for the african people and to protect the environment.
