{"Image ImageDescription": "March 18, 2014 - Washington, D.C., United States: Construction workers install storm water drain pipes at the hydrolysis wastewater treatment project at DC Water at Blue Plains. When completed, it will be the largest thermal hydrolysis plant in the world. Though the practice has been employed in Europe, the water sector in North America has not yet adopted this technology. The process \"pressure-cooks\" the solids left over after wastewater treatment to produce combined heat and power-generating 13 MW of electricity ($10 million savings annually). These vessels can also ingest scraps, fats and grease to generate power ($400 million project).
