Dr. John H. Loughrin is a Research Chemist at the USDA-ARS Food Animal Systems Environmental Research Unit in Bowling Green, KY. He specializes in odor analysis and greenhouse gas management. The goal of Dr. Loughrin’s research is to mitigate the environmental damage done to land, water, and air by excessive application of animal manure to farmland. Specific areas of research include improving the efficiency and cost effectiveness of anaerobic digesters to reduce greenhouse gas emissions, provide renewable energy production and reduce manure volume and strength.

Area of research

• Enhancing the production of biogas from anaerobic digesters at reduced costs
• Studying the effect of sound on biogas production and the microbiome of anaerobic digesters
• Investigating manipulation of the microbiome of anaerobic digestion to reduce the concentration of malodors in animal wastes.
• Reducing and/or capturing dissolved greenhouse gases in animal waste slurries to reduce fugitive emissions of greenhouse gases.
• Uncoupling solid waste retention time from wastewater hydraulic retention time to determine its effectiveness in reducing phosphate and heavy metal pollution.
