Ecological design technology is based on the idea that manmade “machines” can be harnessed to mimic biological systems, giving us the power to restore environmental contaminants and neutralize the build-up of waste on the planet.
     John Todd, a marine-biologist, inventor, and designer, is using eco-technology to address the global wastewater crisis. Todd applies principles of bio-mimicry to create Eco-Machines, which are networks of biological systems built to strategically transform industrial sewage into usable water. Eco-Machines are custom built for size requirements, but they all look like a series of connected fish tanks, each tank a separate treatment zone utilizing anaerobic, flow-equalization, anoxic, and aerobic processes. Water flows through the tanks and sifts lastly through an effluent filter, such as a constructed wetland or fluidized bed, to catch leftover solids. All of this is accomplished without the use of chemical-based inputs that are used in sewage treatment plants, which eject chemically imbalanced water back into water streams, starving our rivers of oxygen with unwanted algal blooms.
     Living Machines are built to recreate the complexity of ecosystem relationships, which are fostered between microscopic algae, bacteria, protozoa, fungi, zooplankton, minerals, snails, fishes, and plants.
