  Anaergia constructed the AD system at Michigan State University which takes organic material from the food service areas of the University as well as the University dairy herd. The solids from the system are used for bedding on the University farm as well as for soil amendment.  

Based on recent discussions with Anaergia, Newtrient has learned that they are reconsidering their participation in agricultural markets.  Anaergia has expressed interest marketing their digestion technology, and also their phosphorus removal, ammonia stripping and biochar technologies.The phosphorus, ammonia and biochar technologies, are currently only deployed in Germany.  Based on these discussions and recent conversations with prospective Anaergia clients, Newtrient believes that Anaergia is once again active in the agricultural space.

Anaergia will be evaluated using Newtrient's 9-point scoring process and Newtrient will add information on their phosphorus removal, ammonia stripping and biochar technologies as information becomes available and North American installations commence.
