The video discusses how sauerkraut juice, a byproduct of cabbage fermentation, is being used to produce biogas. This process not only provides a new energy source but also offers economic benefits to sauerkraut producers by utilizing the entire production process. Previously, the juice was a pollutant requiring treatment, but now it is transformed into energy, powering a local plant and supplying electricity to the grid. The biogas produced is sufficient to meet the energy needs of 1500 people annually, indicating the potential for sauerkraut to become a significant energy source in the future.
