This waste-to-energy project marks a meaningful step forward in the customer's operational strategy by monetizing swine waste through a proprietary pyrolysis process to produce renewable biogas. Capstone's microturbines will convert this on-site biogas into 100% renewable electricity for grid export, while simultaneously delivering high-value thermal energy to support the facility's internal operations. This integrated approach enhances project economics, improves energy efficiency, and creates a scalable model for recurring renewable power generation and long-term revenue growth.

By converting agricultural waste into dependable renewable power and capturing microturbine waste heat for productive use, we create a true circular economy that delivers lasting value to the surrounding community

The project was secured by E-Finity Distributed Generation, Capstone’s distributor for the Mid-Atlantic, Southern United States, and the Caribbean region. The sophisticated array consisting of one Capstone C600S microturbine and six Capstone C1000S microturbines is scheduled for final commissioning in March 2026.

Innovative Circular Economy Solution

“The project represents a significant shift in agricultural waste management. By utilizing pyrolysis, a thermochemical decomposition process, the facility transforms organic swine waste into a clean-burning biogas,” said Vince Canino, President and CEO of Capstone Green Energy. “Our Signature Series microturbines are uniquely engineered to handle a wide operating window, along with variable compositions of renewable biogas - providing a resilient and low-emission alternative to traditional reciprocating engines. By converting agricultural waste into dependable renewable power and capturing microturbine waste heat for productive use, we create a true circular economy that delivers lasting value to the surrounding community.”

Beyond improving operational efficiency, the system serves a broader community purpose. The project was designed as an effective odor-control solution, helping reduce environmental impacts while supporting local renewable energy goals. In addition to producing renewable electricity, the facility is expected to generate Carbon Emission Reduction (CER) credits.

Technological Synergy: Pyrolysis & Microturbines

By combining advanced pyrolysis with microturbine technology, the facility achieves a "circular" energy model. Unlike traditional combustion, this integrated approach:

  • Monetizes Waste: Converts an agricultural byproduct into a consistent revenue stream through renewable power generation.
  • Maximizes Efficiency: The CHP configuration uses the heat generated during electricity production to support the pyrolysis thermochemical reaction, optimizing the project's overall carbon footprint.
  • Scalable Infrastructure: Provides a modular blueprint for other large-scale agricultural operations looking to meet North Carolina’s renewable energy mandates.

In this installation, the Capstone microturbines will operate on biogas produced from swine waste (hog manure), which is converted through proprietary pyrolysis reactors. The clean exhaust heat generated by the microturbine system will be captured and used to heat thermal oil, providing the temperature control required for the reactors used in the biogas production process. This closed design maximizes energy efficiency, reduces waste, and supports continuous renewable fuel generation.

“Projects like this show how distributed generation can provide real operational and environmental value,” said Jeff Beiter, Founder and CEO of E-Finity Distributed Generation. “By converting agricultural waste into renewable power and usable heat, the system supports odor control, improves efficiency, and enables the generation of carbon emission reduction credits, helping align economic performance with ESG goals.”
