Three externally-funded projects on rotating-tank in-vessel composting of waste products are currently on-going through the Department of Agricultural Sciences at Texas A&M University-Commerce. These projects are focused on solving specific waste management problems encountered in agriculture and food production and utilization systems as well as searching for value-added uses for the composted products. The projects currently underway include work on dairy cattle solid waste, poultry litter and mortality, and food residuals.  Most of these projects are being supported through Section 319(h) funds authorized through the U.S. Clean Water Act or through funding provided by the Texas Department of Agriculture. The projects typically focus on installation, management and operation of on-site commercial-sized composters for the specific waste streams. Other exploratory projects include development of in-vessel composting techniques for swine manure and mortality, turkey litter and mortality, hatchery waste, fish processing residuals, biosolids, and paper pulp sludge.  Additional information on these and related activities can be found linked to the author’s homepage at www.TAMU-Commerce.edu/coas/agscience/dlc.html.
