Monarch Bioenergy completes US$150 million manure-to-energy project

In the United States (US), Monarch Bioenergy LLC, a joint venture between Smithfield Foods, Inc. and Roeslein Alternative Energy LLC (RAE), has finished installing manure-to-energy technology on nearly all of Smithfield's Northern Missouri (MO) hog finishing farms. The new technology captures methane emissions and converts them into carbon-negative renewable natural gas (RNG) to power homes, vehicles and businesses.

Roeslein Alternative Energy LLC (RAE) was founded in 2012 as an operator and developer of renewable energy production facilities that convert agricultural and industrial wastes, along with renewable biomass feedstocks, into renewable natural gas (RNG) and sustainable co-products. In 2014, it formed the Monarch Bioenergy LLC manure-to-energy joint venture with Smithfield Foods, Inc (photo courtesy RAE).

Construction of the approximately US$150 million project officially began in 2014, three years after RAE and Smithfield first had the idea to embark on the joint venture. The proprietary processes that emerged from the project create carbon-negative RNG at a rate of approximately 800 000 dekatherms annually.

We are delighted to reach this exciting milestone, which is a significant step toward fulfilling our commitment to implement this transformative, cutting-edge technology on the vast majority of our finishing farms in multiple states. Our Monarch Bioenergy manure-to-energy projects are making a significant environmental impact and remove 25 times more emissions from the atmosphere than are emitted during the clean energy’s end-use. Because of this, they are key projects in our Smithfield Renewables portfolio of innovative renewable energy and carbon reduction efforts across our operations, said Kraig Westerbeek, VP of Smithfield Renewables for Smithfield Foods.

In addition to generating renewable energy, the partnership has planted hundreds of acres of prairie grass, providing ecological services and wildlife habitat for monarch butterflies across the state. The companies are also exploring harvesting prairie plants to create biomass for RNG production.

With perseverance and dedication to our vision, we navigated the pathways for swine manure with the California Air Resources Board (CARB) and the EPA to receive the lowest CI (carbon intensity) scores in the swine industry. We are leading the way to improve the industry’s environmental footprint and diversify its income stream. This is a blueprint on how to turn challenges into opportunities, said RAE Chairman and CEO Rudi Roeslein.

Collectively and independently, the companies have embarked on additional manure-to-energy projects across the country in Arizona (AZ), California (CA), Colorado (CO), Iowa (IA), North Carolina (NC), Texas (TX), Utah (UT), and Virginia (VA).

The Monarch Bioenergy joint venture supports the companies’ respective sustainability goals. This includes RAE’s goal to restore 30 million acres (≈ 12.12 million hectares) of land to native prairie plants strategically located around waterways, streams, rivers, and highly erodible lands and Smithfield’s goals to become carbon negative in US company-owned operations and reduce greenhouse gas (GHG) emissions 30 percent across its entire US value chain by 2030.
