We have over 30 years of experience in the planning, design, construction, and operation of confined animal waste disposal facilities. We have conducted a number of regional animal waste management studies for a variety of governmental and private agencies. We have placed numerous dairy waste treatment and storage facilities in operation throughout the US. We offer a variety of solutions for the recovery of nutrients, elimination of pathogens, and recovery of energy from agricultural waste.

Our AGF process, AGF Contact Process, and Simply Class A processes offer unique solutions to the agricultural industry. We can eliminate pathogens for the nutrient rich fertilizer produced. We can recover nutrients from the liquid stream to meet TMDL requirements. In the process we can generate energy and waste heat for use on the farm.

A short paper on how Cyclus Envirosystems anaerobic digestion technology helps in the control of odors is available, Anaerobic Digestion and Farm Odors

The are a number of challenges in using anaerobic digestion in the treatment of dairy wastes. We have created a number of important technologies that enable us to deal with dilute slurries that derive from flush systems and to deal with sand buildup in the digestors. See our paper, Overcoming the Limitations of Anaerobic Digestion

We have recently completed a handbook on the use of anaerobic technology in treating dairy waste. This document describes different techniques of managing dairy facilities and how this impacts the selection and design of anaerobic facilities. It is available as a 1.7MByte Acrobat pdf file, Dairy Waste Handbook.

In 1997 the National Pork Producers Council announced it's initiative that would find producer friendly solutions to odor from hog manure. A committee was formed to solicit and evaluate biological, chemical, mechanical, nutritional, and management technologies that would abate or eliminate odor. Several hundred companies were provided the opportunity to submit proposals for evaluation of their technology. The NPPC contracted with a consulting firm, Cavanaugh Associates Consulting Engineers to evaluate those technologies. In March, 2000 the NPPC published its final report "Waste Management Technologies Used in the Swine Industries" Environmental Energy's (formerly Cyclus EnviroSystems) technology was ranked the highest of all technologies evaluated scoring a rating of 8.4 out of 10. Please see cover letter and excerpts from this report, Waste Management Technologies Used in the Swine Industry.

The Cavanaugh Engineers describe the AGF technology as follows:

" The AGF process represents some of the most innovative technology seen by this reviewer to date as a potential solution to the nationwide animal waste issue. Many technologies focus on a narrow part of the issue, failing to note that they solve one problem while creating another. This process appears to have anticipated and addressed every facet of the waste treatment problem."
