An hour southwest of Berlin, in the town of Treuenbrietzen, Mozart has played non-stop for two months. The classical composer’s audience? Waste-eating microbes.

As Spiegel Online reports, the German waste-facility’s owners believe the music, coupled with more oxygen, will make their microbes eat biosolids more efficiently, saving money and leaving less residual waste. Their idea comes from the German firm Mundus, headquartered in Wiesenburg, whose founder cites Mozart’s “very good effect on people.”

It’s fairly easy to poo-poo this experiment, especially given other wildly-marketed but later refuted claims attributed to the man’s music. Many of these Mozart miracles first surfaced after Frances Rauscher at the University of California, Irvine questioned in a 1993 paper (pdf) in Nature if listening to classical music could increase adolescent performance on IQ tests. Though Rauscher found that the music did seem to increase performance, later studies showed no effect.

Though the waste-facility spent hundreds on fancy stereo equipment, management hopes the scheme will save them thousands in expenses each year. One only hopes that the music will make their human employees a bit happier at a job that might otherwise stink.
