ASU researcher finds key algae for wastewater treatment but logistics difficult

In Arizona, a researcher at Arizona State University has identified an algae found at the bottom of sulfurous springs in Yellowstone national park that is ideal for wastewater treatment that is more efficient and cheaper than standard treatment methods. The algae are then used as feedstock for biofuel production. Trials are underway at New Mexico State University. Another trial in Phoenix is set to start in a month. Logistics for a commercial sized facility are a major constraint, however, with a wastewater plant serving 1 million people would require 15,000 acres of plastic bags growing the algae and treating the water.
