Salt-tolerant bacteria with an appetite for sludge make biodegradable plastics

The United States generates seven million tons of sewage sludge annually, enough to fill 2,500 Olympic-sized swimming pools. While a portion of this waste is repurposed for manure and other land applications, a substantial amount is still disposed of in landfills. In a new study, researchers have uncovered an efficient way to use leftover sludge to make biodegradable plastics.
