OBJECTIVES OBJECTIVES The objectives of this research and demonstration project were to 1) determine how moisture content affects biogas production rates from beef cattle manure collected from open lots, and 2) evaluate the feasibility of producing biogas using beef cattle manure in a low cost, low maintenance landfill-type cell. SCOPE OF WORK The scope of work, as outlined in the WRBEP Contract No. 55008 dated 7/1/98, consisted of the nine tasks outlined below: Task 1 Laboratory Closed-Cell Biogas Production Experiments Task 2 Biogas and Product Evaluation for the Laboratory Closed-Cell Biogas Experiments Task 3 Construction of Anaerobic Landfill-Cell Digesters Task 4 Add Manure to Cell One and Seal Task 5 Monitor Biogas Production for Cell One Task 6 Add Manure to Cell Two and Seal Task 7 Monitor Biogas Production for Cells One and Two Task 8 Evaluate the Data for Biogas Production for Cells One and Two Task 9 Prepare Final Reports INVESTIGATOR PROFILES AND RESPONSIBILITIES This project was completed as a group effort of several scientists and one graduate student. Profiles of the investigators and roles played by each individual are presented below. Dr. David Parker is an agricultural engineer and assistant professor at West Texas A&M University in Canyon, Texas. Dr. Parker has a 75% research, 25% teaching appointment and devotes his research time to animal waste research. He also teaches graduate courses in agricultural waste management and environmental statistics. Dr. Parker was responsible for overall management of this project, and for preparation of quarterly and final reports. In addition, Dr. Parker was the thesis advisor for the graduate student working on the project. Dr. Darren Williams is an assistant professor of chemistry at West Texas A&M University specializing in instrumental analysis. Dr. Darren Williams was responsible for the analysis of the biogas samples, and served on the graduate committee for the graduate student working on the project. http://www.westbioenergy.org/cattle/objectives.htm (1 of 6) [3/26/2003 8:52:54 AM]
OBJECTIVES Dr. Brent Auvermann is an agricultural engineer and assistant professor employed by Texas A&M University in Amarillo, Texas. Dr. Auvermann has a 35% research and 65% extension appointment. His duties include performing research and technology transfer related to livestock manure management and protection of air and water quality. Dr. Auvermann provided assistance and guidance throughout the project, assisted with data evaluation and interpretation, and served on the graduate committee for the graduate student working on the project. Dr. Andy Cole is an animal scientist working at the USDA-ARS Conservation and Produciton Research Laboratory in Bushland, Texas. Dr. Cole has a 100% research appointment in the area of animal waste management. Dr. Cole provided assistance and guidance throughout the project, assisted with data evaluation and interpretation, and served on the graduate committee for the graduate student working on the project. Mr. J. Shiloh Posey is a M.S. graduate student in Biology at West Texas A&M University. Mr. Posey is originally from Plainview, TX, and was responsible for supervising the construction of the biogas cells, daily monitoring of the experiments and demonstration project, and preparation of a thesis on the project. MATERIALS AND METHODS This project consisted of three laboratory experiments and a field demonstration project. The laboratory experiments were conducted in the Environmental Agriculture Lab at West Texas A&M University’s Kilgore Research Center. The field demonstration project was conducted at the WTAMU Research Feedlot located 6 miles east of Canyon, TX.
