Study Finds Water Use for Switchgrass Ethanol Production Approximately the Same as for Gasoline

Green Car Congress

Consumptive freshwater use for ethanol and petroleum gasoline production. The production of both bio and petroleum feedstocks and fuels requires substantial water input. In many cases, the Argonne team noted, crude oil production is increasingly water dependent. Data: Wu, ANL/ESD/09-1. Click to enlarge. ANL/ESD/09-1.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.
