Project Objectives
Overview of Project Context
Ecolife Foundation, a non-profit organization in environment sustainability, is currently focusing on deforestation in Uganda, East Africa due to tribal charcoal production. The Bwindi tribe uses charcoal as a means of monetary income and to provide for their families. Current charcoal production is extremely inefficient and a main cause of deforestation in the Impenetrable Forest, as large sections of the forestry are cut down to meet the demands of charcoal production.
Ecolife's goal is to prevent this deforestation by making use of biogas reactors to convert branches and shrubs that fall to the ground from the tree tops to charcoal. The fuel to ignite this feedstock will be natural gas created by digesters that convert animal waste into methane with the addition of specific bacteria. This closed system is eco-friendly as it uses natural gas to power the system and does not require forest lands to be cut down to provide the feedstock. As this system has a much higher efficiency, branches and leaves that fall to the ground will be sufficient in maintaining large-scale production, with the possible addition of a few trees instead of hundreds of trees.
Hopefully, in the near future Ecolife will be able to replace current charcoal methods with this highly efficient, eco-friendly system and in doing so, protect the forest's that thousands of species call their home.
Current Charcoal Production Process; Vast amounts of precious heat are lost to environment resulting in low efficiencies
