The University of New Hampshire is celebrating its use of a unique energy recovery composting system. UNH is believed to be the only university in the nation with such a compost facility, which captures generated heat for water that can be pumped to reservoirs and used for wash water, provide pre-heated water for a boiler or be used in heating systems. The system at UNH's Organic Dairy Research Farm, installed last year, preheats water used to clean and sterilize a tank and tubing in the milk room. The compost facility was named for Joshua Nelson, who advanced the technology. Members of his family and former colleagues at Agrilab Technologies of Enosburg Falls, Vermont, recently gathered at the UNH farm to honor Nelson, who died in 2012.
