Wastewater streams could provide the feedstocks for biodiesel production. This article from Water Technology says a new study from Lux Research shows the potential to capture industrial fats, oils and greases (FOG) from the streams to make the green fuel.
Growing demand for biodiesel amid a restricted supply of feedstocks drives recovery of industrial FOG. However, current economics don’t favor lithium and phosphate recovery, noted the release.
“Many current wastewater streams contain resources worth billions of dollars of lost product and lost opportunity,” said Tess Murray, research associate and author of the report titled, “Recovering Valuable Resources from Wastewater.”
“As the value of resources rises, recovery technologies are beginning to make sense for even parts-per-million traces of materials such as precious metals and oil,” she added.
