A Colorado State University study says turning algae into a biofuel is more environmentally friendly than the process for petroleum diesel or soy biodiesel.
The study based its conclusion on the complete process for each fuel and included factors such as the amount of energy used to grow algae, the diesel burned by trucks used to move the algae biodiesel from processing facilities to the pump and the energy used to make fertilizer.
For the study, CSU professors Thomas Bradley and Bryan Willson relied on data from the Engines and Energy Conversion Laboratory at CSU and from Solix Biofuels Inc., a spinoff company from the lab.
The study appears in this week's Journal of Environmental Science and Technology.
