HomeBiogas Clean Cooking Solutions
HomeBiogas tackles one of humanity's biggest challenges: providing carbon free clean cooking to the more than 3 billion people who are exposed to life-threatening toxic air pollutants on a daily basis. We have developed and commercialized a disruptive household biogas system that has made it easy, safe and affordable for families to transition to clean fuels - improving livelihoods while helping to fight climate change. Backed by field trials and extensive scientific research, the innovative system converts families’ organic waste (kitchen, animal, and human waste) into free and clean energy (approximately 6.2kWh/day, equivalent to 3 hours of cooking) as well as organic liquid fertilizer. HomeBiogas systems have been a life-changing catalyst in developing countries, where 4.3 million people die every year due to indoor smoke inhalation from cooking on open fire, access to electricity is sparse and there is a lack of waste management services.
Clean cooking is not a luxury; more than 600 million people in Africa are living in energy poverty. More than 80% of households in sub-Saharan Africa rely on charcoal or wood for daily cooking needs. Many of those underserved, women in particular, spend hours each day collecting firewood for cooking. Left with no other option, they use charcoal and wood-burning fire to cook, which are cripplingly expensive. Businesses and farms spend even more. More problematically, these solutions pour dangerous pollution into homes and endanger health all while exacerbating climate change. The project will address the urgent need to reduce the use of charcoal and wood for cooking in off-grid communities by developing biogas alternatives and bringing these to scale. The project will bring biogas technology to off-grid homes, and eventually businesses. These systems will quickly accelerate local access to clean cooking at an affordable cost. It will also improve the health and quality of life of local people and therefore improve community productivity and vitality.
The direct beneficiaries will include: (1) local communities involved in the charcoal and alternative energy value chains (specifically as it relates to clean cooking), specifically women, youth, and other underserved groups through increased income, improved health (improved air quality) and increased human capacity through renewable energy implementation; (2) provincial and local governments and CSO’s through increased capacity through renewable energy implementation; (3) local businesses through reduced energy costs, organic fertilizer for growing crops, lower energy maintenance requirements, and increased capacity through renewable energy implementation.
HomeBiogas’ main technological innovation is commercializing household biogas systems that are extremely affordable while still meeting the top three wish list of any rural households in Africa - easy to install and use, converting home waste to biogas in a completely safe process, and hours of hours of smoke-free cooking gas. Backed by field trials and extensive scientific research, the innovative system converts families’ organic waste (kitchen, animal, and human waste) into free and clean energy (approximately 6.2kWh/day, equivalent to 3 hours of cooking) as well as organic liquid fertilizer.
The system was built and designed with a safety engineer and passed a rigorous HAZID (Hazard Identification) audit. The product holds a CE certification. The system is built from 3 core elements: 1) A welded inner liner specially designed with the manufacturer to hold the gas and the digested materials 2) An outer liner specially designed for strength, stability and UV resistance; 3) The injection moldings including the system's piping, inlet and outlet.
HomeBiogas 2.0 is made of high-quality UV protected Polyethylene and Polypropylene. All the materials can be recycled, for each part we have quality control plan and process. Feeding rates and digester health can be controlled by: 1) Educating the customer about the correct amounts of waste to feed the system. 2) The system was developed through many years of field research and is designed to hold and properly digest all organic waste of a family / small farm. If the system is not used, the excess gas will be automatically released into the atmosphere by our specially designed pressure-release mechanism. The generated biogas is filtered by a special-purpose activated carbon filter to remove any unpleasant odors and toxic gases such as hydrogen sulfide (H2S). Concerning the smart valve, we plan to build a simple and cheap device on a first stage to be able to open or close remotely the gas depending on payments. On some devices, we will have a flow meter to collect consumption data. Later on, we plan to integrate a pressure sensor to the digester's biogas chamber to remotely monitor the health of every digester. The major part of monitoring the health of the systems will be done by our agents in the field who will visit the customers regularly and be trained to check the health and good usage of the systems.
