Biogas is produced during anaerobic digestion of organic matter. Anaerobic digestion is a process well known from nature, where biogas is produced spontaneously. However, an industrial technology of anaerobic digestion has been developed as a part of waste water treatment process at the beginning of the 20th century. Nowadays, technology of anaerobic digestion is used not only for sewage sludge treatment, but also biogas systems for organic wastes or biomass treatment are built. In this paper, a process of anaerobic digestion is mentioned. A laboratory fermentation unit, built at the Institute of Process and Environmental Engineering (UPEI VUT), is described. The laboratory fermentation unit is used for digestion of new types of substrate and process optimization. Finally, the possibilities of biogas utilization are discussed.

Bioplyn je produkován během anaerobní fermentace organických materiálů. Anaerobní fermentace je proces známý z přírody, kde se bioplyn tvoří samovolně. Technologie anaerobní fermentace však byla vyvinuta až na počátku 20. století jako součást technologie čištění odpadních vod. V současnosti se anaerobní fermentace využívá nejen na čistírnách odpadních vod, ale také v bioplynových stanicích, které zpracovávají různé organické odpady a biomasu. V tomto příspěvku je popsán proces anaerobní stabilizace, dále laboratorní fermentační jednotka, která byla vybudována na Ústavu procesního a ekologického inženýrství. V závěru jsou zmíněny možnosti využití bioplynu.
