Waste to energy

Capturing biogas from cattle, hog and poultry , water treatment plants, food processing, reduces greenhouse gas emissions and provides a cost effective source of renewable energy.

   Methane is a potent greenhouse gas with a GWP about 25 times more powerful than that of carbon dioxide over 100 year. 

 Biogas recovery systems capture and combust methane, reducing virtually all of the methane that otherwise would be emitted. 

The use of biogas to generate energy can also offset fossil fuel use, which in turn lowers emissions of CO2, another critical greenhouse gas.

Biogas can be used as:

-  direct fuel source for heating, boilers, chillers, or drying, or upgraded to a cleaner gas and used as vehicle fuel or put into natural gas pipelines for sale. 

- combustion fuel in an engine-generator to produce electricity. Waste heat from the engine-generator set can be captured in cogeneration power systems and used for heating the digester, or for water and space heating.

 - Another benefit of anaerobic digestion is the variety of byproducts that can be created from the digestate (digester effluent) solids. Examples include fertilizer, livestock bedding, and soil amendments.

Anaerobic digestion provides several water quality and land conservation benefits:

-Destruction of more than 90 percent of disease-causing bacteria that might otherwise enter surface waters and pose a risk to human and animal health. 

 - Reduction of biochemical oxygen demand (BOD).   BOD is one measure of the potential for organic wastes to reduce dissolved oxygen in natural waters., which in turn protects the health of aquatic systems

 Implementing anaerobic digesters on livestock facilities improves soil health.   

The addition of digestate to soil

- increases the organic matter content, 

-reduces the need for chemical fertilizers, 

-improves plant growth,

- alleviates soil compaction. 

 - converts nutrients in manure to a more accessible form for plants to use (nitrification).
