Seven generations of the Wanner family have developed the Wanner's Pride-N-Joy Farm located in Narvon, PA, in eastern Lancaster County. The farm was founded in 1840, and is operated today as a dairy by Alfred Wanner and his two sons, Matt and John, with 600 milking cows. Their goal is to keep the farm a viable economic unit for future generations. Based on the Wanner family's long-standing commitment to environmental stewardship, a major component of their dairy expansion plans is to build a modern and efficient manure management system that will be both labor efficient and improve the environment.

In early 2006, the Wanners began to improve their manure management system by constructing increased manure storage capacity, manure solids separation, and an anaerobic digester. The proposed anaerobic digester, completed in the summer of 2007, produces approximately 2,000 kWh of electricity each day, more than 3 times the amount of electricity the farm currently uses. The Wanners sell surplus generic electricity to their power provider and turned to NativeEnergy to provide an upfront purchase of the RECs and other carbon offsets to help fund the project. Other benefits from the project include producing digested manure solids, which after composting can be sold to landscaping contractors. Digested manure liquids, which are essentially made odorless by the process, will be irrigated on nearby fields as natural fertilizer.
