Date: Tue, 20 Jul 93 15:35:35 -0400 Message-Id: <3374.743196935@KANGA.FAC.CS.CMU.EDU> From: Thomas_Price@KANGA.FAC.CS.CMU.EDU this is from the Late Spring 93 issue of "In Context", no. 35. The article title is "Living Machines" "Pollution problems resulting from the disposal of human waste are relatively new phenomena. For thousands of years, our body wastes were an intricate part of the planet's natural recycling system, providing food and fuel forthe microorganisms at the bottom of the food chain. But with the huge growth in world population and the concentration of that growth in urban centers, human waste has been disconnected from the cycle. ... John Todd and Nancy Jack Todd ... of the Center for the Restoration of Waters at Ocean Arks International ... (have as their goal) to introduce sustainable alternatives to conventional waste disposal, fuel production, heating and cooling, air purification, and food production. The key to accomplishing these tasks is through ecological engineering. By combining living organisms ... in contained environments, OAI has created what John calls Living Machines. ... OAI recently designed and build a sewage treatment Living Machine inside a Toronto school ... students at the Boyne River school use conventional water-based toilets, but once waste is flushed, it is rapidly digested as it passes through four cells -- two with oxygen, two without -- each filled with microorganisms. Next, it is pumped up to the highest of 17 tanks. Here, the students may watch as the water flows through clear tanks first filled with algae, then with higher aquatic rooted plants, and finally with animals including clams, snails, and fish. By the time the wastewater passes through a marsh and pond it is technically well water and legally drinkable." They can get rid of heavy metals and toxic wastes with these things too.
