Combustible materials which are used for cooking, such as firewood and charcoal, are associated with a range of problems in many countries. Gathering these materials is time-consuming and difficult, also, because they are often in short supply. In addition, cooking with these materials can cause significant health problems. Replacing wood fuels, biogas can alleviate such problems while simultaneously reducing deforestation and soil erosion. However, once produced in biogas digesters it is very difficult to transport the gas to the respective households.

The Biogas Backpack aims to provide poor rural households with an affordable source of energy for lighting or cooking, thereby improving living conditions. Helping to avoid the time consuming task of collecting fuel wood, the biogas backpack helps to ease the daily work of women in developing countries. In addition, health risks can be minimized as burning biogas is nearly smokeless.

This solution was developed in order to facilitate the sale of biogas in developing countries and therefore makes it possible to start a business.
