A Slovenian brewery, Pivovarna Lasko, launched a research project on the use of brewer’s yeast in the generation of biogas in anaerobic digestion. After successful results, the company built its own anaerobic waste water treatment.
Through the biogas production, Pivovarna Lasko contributes to providing a significant share of renewable energy from its own by-products in addition to achieving efficient waste treatment. By adding yeast to the waste water used to make biogas, Pivovarna Lasko generated 40% more biogas and saved up to 18% in natural gas consumption, which means more than €80.000 of annual savings, at a natural gas price of € 0.3per/m3.
