Biofilters for Animal Agriculture Air Quality Curriculum Materials

Air emissions from animal agriculture operations and their associated manure storage are being examined more closely for ways to mitigate potentially harmful gases. One of the options being evaluated is biofilters.  The materials on this page were developed to assist educators and professors who include biofilters as a topic in their classrooms or educational programs.
