Processing cost is a great hurdle for manufacturing biodiesel from algae. But New York researchers claim that their pioneer method is at least forty percent cheaper than the current manufacturing processes. We already have necessary infrastructure for supply of biodiesel fuel. Amount of algae is also not a problem. We have abundance of algae growing in the major water bodies of the world, be it ocean, lakes or rivers. The research team calls this method �continuously flowing fixed-bed.� According to the team members, this process will not produce wastewater which causes pollution. Ben Wen also explains that algae has an �oil-per-acre production rate 100-300 times the amount of soybeans, and offers the highest yield feedstock for biodiesel and the most promising source for mass biodiesel production to replace transportation fuel in the United States.�
They are also using a proprietary solid catalyst developed in their laboratory. Other biodiesel producing firms are using liquid catalysts. Liquid catalysts cannot be used again and again but solid catalysts can be utilized repeatedly. The second key advantage of having a solid catalyst is that a continuous flowing production of biodiesel can be maintained. The same is not true with liquid catalysts. Using liquid catalyst is time consuming too. Workers have to take extra half hour after producing each batch to create more biodiesel. Liquid catalyst is present in the biodiesel. So to get rid of the liquid catalyst workers need to purify the biodiesel by neutralizing the base catalyst by adding acid. But by using solid catalyst no such action is needed.
Ben Wen is trying to test the new waters. He is thinking big. According to him, his firm is currently conducting a pilot program for the process with a production capacity of nearly 1 million gallons of algae biodiesel per year. Depending upon the size of the machinery and the plant, he said it is possible that a company can produce up to 50 million gallons of algae biodiesel every year.
But this is not all. There is icing on the cake. Wen explains further that the solid catalyst continuous flow method can be tailored into mobile units so that smaller companies wouldn�t have to construct plants and the military could use the process in the field.
