Kilowatts from Cow-pies Review

            The future of water in an industrial setting is a real problem with the growth in population over the last 100 years. The Earth’s surface is covered with 70% water, and only 2.5% of that water is fresh water. Most industrial facilities cannot operate by using salt water, and the combination of these factors makes fresh water a precious commodity. The film “Kilowatts from Cow-pies” gave some solutions to this problem. The most impressive system set up in the movie to me was the first facility Kaplan Farms. The plan was a complete circle with water cleaning to reuse the cow pies and create methane to run the facility. Another impressive point of the design of their facility was that the land they chose to build on was a brownfield site. They integrated an automated system for gathering cow feces with water and sent the slurry water to an anaerobic digester. The digester would then break down the wastes and release methane. That methane was then collected and piped to an electric generator and burned as fuel, which was used to power the facilities. After that process, the water was drained into one of three separation ponds, where it was cleaned up through settling, algae, and then fish before being pumped back up and reused. The dried feces was then composted with left over from the slaughterhouse to become fertilizer for the fields that grew hay for the cows. This closed system is an ideal example for industrial applications and a possible crossover design for other businesses. Closing the loops in the industry is good for the environment and a sound business practice that increases profits.
