Making Algae Work

Establishing algae farms near industrial facilities might be a way to make algal biofuels economically viable, writes Mark Fischetti at Scientific American. He says that waste from other industrial processes, which could include CO2, nitrogen, or phosphorus, can be routed into the algae facilities, knocking down both an input cost barrier and solving a waste issue. “Whether such combinations will make algal biofuel commercially competitive remains to be seen, but it seems likely that co-location will be a big factor making a sizeable industry possible,” Fischetti writes.
