In a recent study conducted by researchers at the University of Virginia and published in Environmental Science & Technology, the authors claim that algae causes more harm to the environment than traditional biofuel crops like corn.
However, in this study, the researchers used algae production data from at least a decade ago.
In response, Andres Clarens the lead author of the study said he used the most recent data that he could, which was about 10 years old. Algae biofuel companies keep their research a closely guarded secret, he said.
