In Cameroon, about 91% of households and restaurants use charcoal and firewood for cooking. This high consumption has a negative impact on the forest and mangrove ecosystem, resulting in reduced catches, risks of coastal erosion, flooding and global warming. As an example, the program to support the implementation of the rural development strategy in Cameroon mentions that Cameroon consumed 356,000 tons of coal or almost 2.5 million m 3 of wood between 2017 and 2018, which corresponds to 18,500 hectares of destroyed natural forests. Moreover, the use of charcoal and firewood for cooking is very polluting and bad for health. The indoor concentration of harmful pollutants from a typical wood-fired cooking cooker produces carbon monoxide and other harmful fumes in the range between seven and five hundred times the permissible limits (World Health Organization, 2004). Moreover, alternative fuels for cooking, such as natural gas and oil, are tooexpensive for the majority of the population.
As a solution concept, Nakupenda e.V. aim to establish an ecological charcoal workshop in Cameroon with its local partner the association ASCON. The workshop should produce charcoal free of pollutants from organic waste provided by households and restaurants. The workshop will train young people in the use of this technology to build ecological charcoal factories.
