While some people listen to the music of Mozart to gain psychic composure during commutes, a sewage plant near Berlin plays Mozart to biomass-eating microbes to make them work faster. It seems that Mozart makes sewage-munching microbes more efficient. The increased efficiency could save the plant as much as $1,000 per month in reduced sewage sludge disposal costs.
The company in charge of the operation feeds the microorganisms oxygen and the sonic waves of Mozart’s compositions to make them work more efficiently. Savings on energy costs and a reduction in the sludge produced saves money.
