ZEOLITES FOR WASTE MANAGEMENT IN DIARY FARM.

• Waste management is an important issue in livestock, with each producer looking for a better way to manage waste. The biogas has been implemented in some farms now the use of Zeolites is another option. Dean Swagger is a dairy man, with a dairy herd of approximately 4,000 head, handling manure in a way that is friendly both to his neighbors and the environment is a key priority. That’s why he has partnered with Mario de Haro-Marti, University of Idaho Extension educator in Gooding County to test different methods for handling dairy waste. De Haro-Marti specializes in dairy and livestock environmental education.One the new methods that shows promise is a zeolite filter to remove ammonia and odor from a dairy manure flush system’s pit. Swagger Dairy has a mix of flushed free stalls and open lots. The collection pit receiving the flush water was capped during the summer of 2015. Gases were collected using a fan with variable frequency drive connected to floats and then passed through a self-contained pressurized zeolite filter. Zeolites are highly absorbent porous minerals, composed largely of silica and aluminum. They are useful for their ability to capture and hold a variety of undesirable materials, much like a sponge absorbs water. Zeolites have long been used in water filtration systems or in aquariums. Preliminary results from three replicated on-farm trials showed that the ammonia levels were reduced from 53 to 92 percent in 2015. Odor emissions were also reduced by 45 percent. The project was funded through a USDA Natural Resources Conservation Service Conservation Innovation Grant. Based on those results and what he observed during the trial period, Swagger believes the zeolite filter worked but he’s not convinced it’s a solution for everyone.
