Efficient Conversion of Waste Streams to Biomethane
Anaerobic digestion (AD) is a renewable energy process that converts biowaste into fuels such as natural gas methane. Current knowledge confirms that this process produces natural gas using various sources of biowaste, but only a portion of the gasses produced are usable gasses such as methane. Biological pretreatment methods have proven effective to increase gas yeilds in the pretreatment of various substrates; however, would be hindered were nitrogen, in the form of ammonia to build up.
By building a calibration curve, and testing samples throughought the pretreatment process, we have confirmed that ammonium concentrations do not rise to a level detrimental to biological processes. Our data suggest that pretreatment of waste activated sludge and cow manure by C. bescii followed by anaerobic digestion in a semi-continious process has the potential to produce enough methane gas on a commercial scale to be considered a practical form of renewable energy.
