About this course

Biogas is mainly a blend of methane and carbon dioxide, produced by microbial communities under anaerobic conditions. Biogas may be produced from all kinds of organic material, and used for production of heat, power and fuel or as a feedstock in chemical industry. A biogas process will also produce a nutrient-rich digestate which may be used as a fertilizer.

In this course, the student will learn the fundamentals of biogas technology, including topics like microbiology, process technology, modelling, digestate, pretreatment and industrial applications. The course sheds light on UN Sustainable Development Goals

  • 6-Clean water and sanitation
  • 7-Affordable and clean energy
  • 12-Responsible consumption and production.
