  7. 9. Duckweed Factoids: <ul><li>Simplest and smallest vascular plant on earth </li></ul><ul><li>35-44% protein, similar to soybean </li></ul><ul><li>One of fastest growing, doubling biomass every 30 hrs, 40 metric tons DW per year (unimproved strains) </li></ul><ul><li>Can produce 5-6x amount of starch of corn per year, making it a strong candidate for ethanol </li></ul><ul><li>Easily digested and assimilated by animals </li></ul><ul><li>Can absorb 86% of nitrogen, 65% of phosphates in tertiary wastewater systems in ten days. </li></ul>
  8. 15. Paul Skillicorn, Austin, TX <ul><li>Current project- Lima, Peru, development of city park with circular duckweed ponds with paths as in a nature garden. Redundant system features automated harvesting, residential wastewater remediation, aquatic worm digestion of solids, fertigation of local farmlands, solar drying of duckweed for pelletized animal feedstock. Water used 4x before allowed to evaporate/dissipate. Is showing a profitable ROI. </li></ul>
