Biofuel from rotting domestic waste is being used to help Solea reduce the impact of its plant in Memphis, Tennessee. The company's manufacturing site
there uses landfill gas from a 474-acre landfill which is collected, compressed and piped to Solae.
The firm says using methane from this source has had the equivalent effect of taking thousands of cars off the road and displacing the use of more than 67 million gallons of gasoline in its first two years of operation, according to updated U.S. Environmental Protection Administration estimates
Solae is joint venture between Bunge and DuPont.
