the units with cattle dung, the production of biogas increased gradually. The results to be published will be discussed with CVE first. Introduction of household biogas digesters in rural farming households of the. The team will be asked to sign a non-Disclosure Agreement. Technical and business case analysis done by CVE will be shared to the Team. Public actors (French organization such as ADEME, ATEE, …), private actors (GrDF (gas company), industrials, start-ups, energy clusters…) and civil society (residents, NGOs…) could be involved in this project in one way or another. The Work performed by the students will be used to assess the feasibility of a Proof of Concept on a Biogas Unit in Occitanie region that will be put in service in 2023. Various issues could be assessed and taken into account in the analysis by the team such as: biobased CO 2 acceptability, carbon impacts assessment of the different models, economic issues, CO 2 Market evolution, etc. The challenge includes a European Benchmark of such models, a local market analysis to identify and assess biobased CO 2 users, the design of models of interests to be studied, and CO 2 impacts assessment for such models compared to a reference model of conventional CO 2 logistics. The Challenge proposed consists in analysing at a territory level around a Biogas project in Occitanie Region (region of Toulouse): the value chains, business potential and carbon impacts of a biobased-CO2 valorization model in circular economy. If your family lives in a rural setting, you might have access to much more organic biomass and you will produce considerable amounts of home biogas to heat all your water and power your whole living area. CO 2 valorization has been identified as an interesting axis in order to grow biogas local acceptance, its competitivity and lower its environmental impacts. A small home biogas unit in an urban or city environment can produce useful amounts of biogas from just a 1Kg or so of organic waste per day. study examined the cost-capacity relationships of biogas plant use while considering the financial and economic feasibility with several decision making. The unit developed process an average of 30,000 tons of waste a year and produces around 17 to 35 GWh of biomethane per year of which 2000 to 3000 tons of CO 2 that are, for now, rejected in the atmosphere. They enable communities and businesses to produce local, sustainable energy by recycling their organic waste through a “circular economy” approach. CVE is active in the photovoltaics solar, biogas, and hydroelectric markets. For Biogas production, CVE has developed a strategy that focuses on deploying dedicated biomethane units to recycle local organic waste streams. of the biogas digester and integration of the unit into the farming / household. But this unit I have seems to be one of the first commercially available units designed for use in the developed regions of the world too. CVE () is a French independent producer of renewable energy across multiple countries and sources of power. Sector development in large scale dissemination of domestic biogas. Based on similar technology and systems, home biogas is produced in developing parts of the world for example, there are 27 million similar units in China and 4 million similar units in India.
