Development and Application of the Newtrient Evaluation Assessment Tool (NEAT):  A Methodology for Comparing Manure Treatment Technologies

The recent development of the Newtrient on-line catalog (www.newtrient.com/Catalog/Technology-Catalog; see accompanying conference proceedings about the catalog) revealed the need to establish a set of environmental and farm operational based critical indicators (CIs).  The indicators are useful in identifying manure treatment technologies that primarily best address dairy farm environmental sustainability but include some social aspects.

Considerations in Evaluating Manure Treatment Systems for Dairy Farms

Advanced manure treatment may become a major system on some dairy farms in the future.  Reducing the impacts of excess nitrogen and or phosphorous may be necessary on farms with a limited or remote land base.  Additional treatments to recover solids, extract energy, concentrate nutrients, reduce odors, reduce the mass/volume, and/or reduce pathogens may become more of a priority as farms seek to move toward sustainability.  

Impact of Anaerobic Digestion on Solids, Nitrogen, Phosphorous, Potassium, and Sulfur Concentrations of Swine Manure

Anaerobic digestion of swine manure is a treatment process that can be used to reduce odor emissions, generate bioenergy, and reduce methane emissions. Studies and models are available that can be used to quantify methane production, and volatile solids (VS) reduction rates. Few provide information on the plant nutrient contents of digested manure.

Purpose

To provide a forum for the introduction and evaluation of technologies that can treat dairy manure to the dairy farming community and the vendors that provide these technologies.

What Did We Do?

Newtrient has developed an on-line catalog of technologies that includes information on over 150 technologies and the companies that produce them as well as the Newtrient 9-Point scoring system and specific comments on each technology by the Newtrient Technology Advancement Team.…
