The Varcor system is transformational to manure management on dairy farms. Using this technology, farmers can achieve compliance with environmental regulation while accruing significant cost savings as well as additional revenue streams. With Sedron Technologies’ Varcor system, manure will be efficiently distilled into 1) water clean enough to provide to the cows, 2) dry, sterile and stable solids for bedding and/or soil amendments, and 3) concentrated liquid, organic nitrogen fertilizer.
Through the implementation of this technology, farms will recognize significant energy efficiencies from reductions in on-farm electrical and fuel use required during manure management activities such as wastewater storage, agitation, pumping and hauling, as well as associated labor and maintenance costs. Significant additional environmental and energy-related benefits include becoming a zero-discharge dairy, GHG reductions due to reduced storage lagoon wastewater volume, as well as displacement of inorganic fossil fuel-based fertilizers.

Manure is collected, combined with wash and process water and pumped to storage lagoons until safely applied to fields as a fertilizer when the crops need the nutrients. Usually, little to no treatment happens prior to lagoon storage, and its contents remain contaminated by high levels of fecal coliform bacteria. Rain further dilutes the manure, adding as much as 2 to 5 times the volume of water to these lagoons. If improperly managed, manure stored in these lagoons can contaminate both surface and ground water with nutrients and pathogens.
Used on a small number of dairies, anaerobic digesters are effective at producing biogas, but do not completely eliminate fecal coliform bacteria nor provide nutrient recovery. They also require significant capital investment. Farmers generate limited income by combining other organic waste materials with the manure, which can significantly increase the amount of nitrogen and phosphorus produced when compared to manure alone. These added nutrients often force farmers to acquire more land and lower application rates in order to balance these additional nutrients with crop production—adding considerable time, effort and expense to the farmers’ bottom line.

Farmers can expect to see their operational costs come down due to recycled water use, as well as reduced transportation and pumping costs.
The concentrated, aqueous ammonia output of the system is a high-quality fertilizer that can be used around the farm.
With the Varcor, farmers can dramatically reduce their impact on waterways and the ecosystems they support.
The waste is processed into consolidated, easy-to-handle outputs at a reduced volume that is easier for farmers to handle.
