Liquid swine manure can have negative effects on the environment such as soil leaching with P and N, pathogens in digesters, and emissions of green house gases. Some of these effects can be alleviated with the manure being put into an anaerobic digesters which can also reduce the odor and create energy. To test the usefulness of anaerobic digesters researchers tested different combinations of manure and organic materials, the test treatments were liquid swine manure, liquid swine manure mixed with corn silage and liquid swine manure mixed with shredded sugar beets. The main objectives of this study were to test liquid swine manure by itself and with typical organic additives, and measure biogas production and digestate quality, to recorded logistical considerations for each manure additive, and to find gas yields from the manure combinations used and the costs of producing electrical power from each combination. When liquid swine manure was put by itself into the digester the total amount was 11 700L about 244L per day, this produced 264 m3 of boigas that was an average of 68% methane. For liquid swine manure mixed with corn silage the digester had some problems handling the solid material, as it designed for liquid only. A chopping pump was implemented to make the straw more liquid like. 227kg of corn silage was added to the digester along with 4681 L of swine manure. This was an average of 5.82 kg of corn silage per day and 120 L of liquid swine manure. This produced 214 m3 of biogas that averaged 55.8% methane – resulting in the production of 119 m3 of methane. The average biogas production was 5.5 m3 per day. The sugar beet additive was the last test recipe, it involved 99 kg of sugar beets, along with 560 liters of swine manure. This was an average of 5.5 kg of sugar beets per day and 31.1 L of liquid swine manure. This produced 13.6 m3 of biogas that averaged 54.7% methane, yielding 7.44 m3 of methane. The average daily biogas production was 0.756 m3 per day. After comparing the data recovered, some observations that were made include liquid swine manure produced the most methane per kg of additive. The sugar beat recipe was the last for methane produced per kg of organic matter but the researchers believe this is underestimated because of complications with the equipment.
