Imagine you're eating dinner on a ceramic plate and drinking water from a plastic cup while sitting in a brick house a seemingly ordinary scenario except that your plate, cup, and your home are all fashioned in part from recycled feces. In my upcoming book, "Flush: The Remarkable Science of an Unlikely Treasure," I describe how the misunderstood byproduct of our daily living is a vastly undervalued natural resource. Try to reimagine wastewater treatment plants ... doubling as multipurpose resource recovery facilities. As an alternative to plastics made from fossil fuels, for example, researchers are making headway in producing safe and biodegradable bioplastics from existing waste streams. Creating planet-friendly bottles, containers, and other bioplastic products from what we leave behind is still a work in progress, said Zeynep Cetecioglu Gurol ... at the KTH Royal Institute of Technology. Developing an efficient and affordable method for recovering new products from wastewater could help offset the money, time, and effort spent by treatment plants to meet pollution limits in discharged water. "It's a win-win," she said. Engineers ... have focused on relieving the environmental problem of excavating clay soil for brick production, in part by exploring how to incorporate treated sewage solids, or biosolids, into fired bricks. Bricks with varying amounts of treated biosolids from Melbourne residents weren't quite as strong as traditional counterparts. But they were lighter and better insulators.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
