2011 Annual Report
1a.Objectives (from AD-416)
To apply sub-surface electromagnetic soil conductivity methods combined with other remote-sensing technologies to identify suitable feedlot bio-solids for direct combustion.
1b.Approach (from AD-416)
Texas Agri-Life Research-Amarillo will provide extensive knowledge of combustion processes and properties related to cattle feedlot bio-solids as a fuel. Furthermore, Texas Agri-Life Research will coordinate with the Texas Cattle Feeders Association to facilitate access to commercial feedlots in the Texas Panhandle for sub-surface surveys, feedlot soil samples, and feedlot management information. Soil samples will be analyzed for combustion properties and chemical constituents by USDA-ARS and Texas AgriLife Research. Models relating soil sample constituents and combustion processes will be refined by Texas AgriLife Research and USDA-ARS scientists. Additional model development for attributes of the feedlot surface, such as depth of bio-solids accumulation, will be developed by Texas AgriLife Research and USDA-ARS scientists.
ARS scientists teamed with Texas AgriLife Extension and Research Center to develop an approach for energy recovery from manure on feedlot surfaces. ARS scientists refined technologies for identifying zones on the feedlot surface with recoverable energy. Texas A&M developed processes that enable the effective combustion of beef manure as a fuel during coal-fired energy generation. This process not only recovers energy but improves the air quality of the combustion exhaust gases. The Office of Technology Commercialization at Texas A&M University has applied for a patent for this combined system.
The ADODR monitors this NFCA with routine personal meeting, emails and telephone conference calls with the Texas A&M principle investigator.
