Proven Performance Through Independent Validation

Aerial view of an aerobic manure lagoon with floating oxygenation and circulation systems demonstrating proven, independently validated performance of Enviro.Farm’s RIBC™ technology. Enviro.Farm’s aerobic treatment technology has been independently validated through a multi-year Conservation Innovation Grant (CIG) administered by the USDA Natural Resources Conservation Service (NRCS).

The project evaluated aerobic manure lagoon treatment across multiple livestock operations, confirming environmental, operational, and economic benefits under real-world conditions.

Project Scope and Demonstration Sites

The CIG project installed floating oxygenation and circulation units on manure lagoons at 11 livestock sites across Wisconsin, South Dakota, and Nebraska, managing manure from more than 10 million pounds of animal body weight.

The study was conducted over several years to confirm reliability, repeatability, and long-term performance under varied climates and farm conditions.

Air Quality and Emissions Reduction

The project demonstrated measurable reductions in air quality impacts by maintaining aerobic lagoon conditions that suppress anaerobic gas formation.

Maintaining controlled oxygen levels prevented the formation of nitrates and nitrites that contribute to secondary emissions.

Pathogen and Odor Control

Aerobic treatment significantly reduced pathogen levels within treated lagoons.

Nutrient Retention and Water Quality

The project confirmed that aerobic lagoon treatment retains nutrients in crop-ready form while improving water quality outcomes.

Operational Reliability

Equipment performance and reliability were validated over the full duration of the study.

The study addressed prior skepticism surrounding floating circulator durability and confirmed suitability for long-term agricultural use.

Economic Outcomes

Beyond environmental benefits, the project demonstrated strong economic advantages for participating operations.

These outcomes established a clear business case for aerobic manure management independent of carbon credit markets.

Conclusion

The Conservation Innovation Grant project confirmed that well-designed aerobic lagoon treatment systems are effective, reliable, and economically viable.

The findings support broader adoption of aerobic manure management as a practical solution for reducing emissions, improving nutrient efficiency, and enhancing environmental performance in agriculture.
