Energy Production

Roeslein Alternative Energy’s vision for prairie restoration comes full circle and is supported by the potential for energy generation that it creates. Through the use of anaerobic digestion, harvested prairie biomass is broken down into methane and used to produce Renewable Natural Gas.

By partnering with livestock farmers, RAE is able to further the benefits of prairie as a biomass feedstock by combining it with organic manure waste generated by the farms. Livestock waste is a significant source of methane gas which is converted to pipeline quality Renewable Natural Gas and can be sold at market rates.

Roeslein Alternative Energy brings all of the biomass feedstocks together with anaerobic digestion technology to provide a valuable resource for land and farm owners. RAE provides additional value by orchestrating the business, finance, and technical aspects of all phases of project development.

Roeslein Alternative Energy offers a turnkey solution to ensure that the finished project is successful, sustainable, and allows customers the ability to focus on their core business.

Groundbreaking Innovation Delivers Numerous “Firsts” for RAE

  • First to invest over $50 MM for proof of concept without Federal or State aid
  • First EPA Swine Registration
  • First EPA “Cluster” Registration


  • First Virtual Pipeline Registration
  • First CARB Swine Pathway Registration
  • Highest price ever received for a cellulosic D3 RIN
  • Lowest CI (Carbon Intensity) Score for CARB ever achieved

How Does It Work?

By placing covers over hog manure lagoons RAE is removing greenhouse gas emissions equivalent to removing more than 25,900 passenger vehicles off the roads.

What Are the Benefits?

Covering the lagoons aids in protecting human health by reducing pathogens through the anaerobic digestion process and provides $120 million of investment into the local economy.

Who Can Make a Difference?

The process diversifies farm revenue by allowing farmers to enter into multiple industries while reducing operating costs by producing renewable energy that can be used or sold.

Through Innovation and Risk

With the goal of giving farmers the opportunity to be in the energy market, RAE began working with Smithfield Hog Production of Missouri on their Northern Farms; this would be a $100 million renewable biogas project. The project centered on gathering hog manure into covered lagoons and capturing the methane gas released through the natural anaerobic digestion process. The captured gas would then travel through equipment for cleaning and compression in preparation of injection into the pipeline. RAE’s role as a developer in the project ranged from full engineering of the systems to fabrication and/or procurement of necessary process systems, progressing to project installation, commissioning and start-up.
