The National Academy of Sciences' report on the sustainability of algae biofuels highlights concerns that have already been resolved, industry heads said yesterday.
NAS released a comprehensive report yesterday, identifying potential issues of sustainability in the burgeoning algal biofuels industry.

Companies are already recycling potentially polluting nutrients and using water that is too salty or too dirty for other uses. Sustainability is a priority, but so are economics, said John Williams, a spokesman for the Algae Biomass Organization.
