Beer and Bacteria to be used in Toxin Cleanup
GospelHead821 writes "According to this article in Popular Science, a chemistry student at the University of Tulsa is driving research into use of toxin-munching "sulfate-reducing bacteria" (SRBs) to help cleanup toxic, solid effluent from abandoned zinc and lead mines near her home. Where does the beer come in? Apparently, it has proved an excellent food source for the bacteria and helps to extend the lifespan of the normally short-lived SRBs by several months. Currently, the procedure is in the testing phase, with models being employed to simulate the conditions that would be present in a large-scale detoxification plant, which in turn, is based on the natural wetlands from which these bacteria hail."
Think about it, instead of having to pay to dispose of failed batches of beer or raw materials that didn't quite pass QC, the brewing companies can sell their waste and minimize or even mitigate their losses. This reminds me of how in the early days of the steel industry, the byproduct of steel production, ethylene glycol, was often dumped in local rivers. Once the usefull properties of this substance were revealed, a former waste product became a valuable commodity. Maybe one day this kind of recycling will be the norm rather than the exception. But for now, citizens of industrialized countries, and especially America, seem content to throw away wealth in the form of unrealized potential of used goods and byproducts, or outright burn it by spewing it out the exhaust of grossly inefficient SUVs. We have a long way to go towards a sustainable, green economy that delivers on the promises of modern living, but these new innovations in recycling and pollution cleanup are a step in the right direction.
