  • Who is the BioRenGaz offer aimed at ?
    BioRenGaz offers its technology and expertise in the realization of studies and the design-build of methanation installations to all stakeholders in the biogas sector: - Farmers - Local authorities - Manufacturers - Developers-Investors - Agri-food industry - Specifiers - Engineering firms
  • What is methanization ?
    Methanization is a biological process of organic matter degradation by bacteria in the absence of oxygen. For this reason, it is also known as "Anaerobic digestion." Methanization provides the opportunity to valorize organic waste that would otherwise be completely wasted or thrown into regular waste, to produce a source of green and renewable energy, biogas.
  • What are the sources of organic matter ?
    BioRenGaz is developing a patented methanation technology in Strasbourg that valorizes liquid or even pulpy materials such as bio-waste soups. Bio-waste corresponds to organic waste derived from natural plant or animal resources : Community waste Agri-food industry Brewery, distillery, cheese factory, sugar factory, etc. Waste from livestock farming Waste from wastewater treatment plants (WWTP)
  • What are the deposits of organic materials ?
    Organic materials come from various sources, essential for recycling and sustainable valorization. Among the main deposits, we find : - DCT bio-waste - Table waste, milk - Cooked brewer's yeast, apple pulp, distillation residues - Slurry, white waters - Sewage sludge
  • What is biogas ?
    Biogas is produced by the fermentation of organic waste from plant and/or animal origin in the digester. It is composed mainly of methane (CH₄), carbon dioxide (CO₂), water vapor, traces of sulfur gases (H₂S) and other minor compounds that vary depending on the type of substrate being methanized. ​
  • What are the ways to valorize biogas ?
    Several valorization methods for biogas are available: • Heat and electricity production using a cogeneration engine, or just heat production with a biogas boiler. The heat produced is generally used on-site for heating digesters and buildings, for the hygienization of food bio-waste, and for heating industrial processes. • Biomethane production by purifying biogas to a methane content of over 95%, then compressing it to inject into the natural gas network. • Biomethane fuel production (BioGNV). Various types of vehicles can run on GNV, offering a more environmentally friendly alternative to fossil fuels (diesel, gasoline) with a significant reduction in emitted particles (50-90% less NOx*). *Source
  • What is digestate ?
    Digestate is the residual material after the anaerobic digestion of organic matter. It consists of fertilizing mineral elements such as Nitrogen, Phosphorus, and Potassium, trace elements, and residual organic matter. Water is also retained during the anaerobic digestion process. Its agronomic value is twofold: it serves as both a fertilizer (providing nutrients to plants) and an amendment (providing nutrients to the soil), representing significant potential for agriculture. The latter is a natural fertilizer spread on neighboring lands, replacing chemical fertilizers whose production and transportation are energy-intensive.
  • What is the future of digestate ?
    Digestate is considered as a waste that should be valorized by spreading it on agricultural lands or transformed into a product through composting or blending with other materials.
