1. Algae comments during Quarterly Earnings Call, Green Plains Renewable Energy (GPRE)

    I found an transcript of last week’s quarterly earnings call with Great Plains Renewable Energy.  GPRE is partnered with BioProcess Algae, LLC. to operate a facility in Shenandoah, Iowa, which grows algae on attached biofilms, using CO2 from a co-located corn ethanol processing plant.

    Unfortunately, there seems to be some typos in the transcript, particularly in paragraph 2 regarding UV rays.

    The full call transcript is available at the link below.  (You would need to register with SeekingAlpha, which is free. NOT AN ENDORSEMENT)

    Green Plains Renewable Energy Inc. (GPRE) Q2 2013 Earnings Call July 31, 2013 11:00 AM ET

    Todd Becker, CEO, Great Plains Renewable Energy, Inc.

    As we told you in the last call, Bioprocess Algae was awarded a $6.4 million grant from the U.S. Department of Energy. This does not take away or from our focus or our end game of converting carbon to a value added product derived from corn.

    Let me give you an update on our progress. At this time, we are recuperating our grown median, all the reactors that are operating. We found that the UV rays, the greater the ability to hold our media firm over time. When this is done, we will see more consistent production in our reactors. This is a bottle-neck that was not anticipated but has been solved at very little cost.

    What I would like to share with you is the ability of our platform. We now have the turnkey ability to grow inoculums in a laboratory and move through our seed reactors, grow it up on the media and our growth reactors, harvest that Algae, dewater the algae, convert it to solid through this process and dry it to biomass. This all happens in a seamless process in Shenandoah today.

    We have a drier now installed on site, which is a change from the last time we discussed the project. The way we go from here, once the retro-fill is complete, we can then focus on actual yields at a steady state to determine a long-term economic capability of this platform. We will focus on all products along the value chain and start to more aggressively focus on end-use markets.

    "This project is either going to confirm these [TEA] results or it’s going to get worse"

    "Will the digestate provide the same substrate for bioflocculation as the waste water?"

    "We just don’t flush the toilet enough in the US to make all the fuel we need"
