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.

Treatment Needs for Water and Nutrient Recycling

This livestock industry panel will present perspectives on livestock producer needs for liquid manure treatment technologies for on-farm sustainability, with emphasis on managing water and nutrients for reuse. Intended outcomes are to engage stakeholders in assessing farm needs and to foster improved connections between livestock producers and technology providers.…

Overview of the U.S. Agricultural Biogas Industry and AgSTAR Technical Resources

AgSTAR is a voluntary program coordinated by the U.S. Environmental Protection Agency (EPA), in cooperation with the U.S. Department of Agriculture (USDA), that supports farmers and industry in the development and adoption of anaerobic digester (AD) systems. In addition to producing biogas, AD systems can help achieve other social, environmental, agricultural and economic benefits.

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.  

Newtrient Manure Technology Catalog: An On-line Resource for Farmers, Their Key Advisors and Others Involved in Dairy Manure Management

Looking at the manure-management technologies that currently exist and the new and emerging technologies, Newtrient provides a reliable, third-party technology evaluation tool for the dairy industry. Three years of time and effort has been put into evaluating almost 300 technologies that are included in the catalog, over half of which are related to biogas production or digestate management.
