The Black Soldier Fly Larva Revolution

The Black Soldier Fly Larva Revolution
Watch "Behind The Scenes At Chapul Farms: The Black Soldier Fly Larva Revolution" HERE 

Our GPS has directed us to a small gravel road just off a two-lane highway, less than a mile outside of McMinnville, Oregon and we just didn’t see it coming. The road sign is handmade and nailed to an oak tree. After discovering our mistake and turning around, we serve our truck past potholes full of spring rain to a modest farm with buildings that were passed down four generations and one that is brand new. It is within this new building Chapul Farms CEO Pat Crowley and his are attempting to revolutionize the world’s organic waste removal system.Much about their project is, at this stage, small. But they have very big plans.


Pat and Director of Project Management Todd Severson (also an owner at Mac Market, a local collaborative eating, drinking, and gathering place in McMinnville) and the farm’s owner Ramsey McPhillips greet us as the sun breaks through the towering blue and purple clouds.Crowley gives us the pitch.Crowley and his team want to restore biodiversity to agriculture, soil, and planet earth for a more resilient, sustainable, resilient, and secure food system. The believe diverting organics from landfills is most actionable item to address climate change. The problem is the current system lacks the infrastructure and scalable technologies to make this shift. The solution? Black solider fly larvae.

“These larvae are remarkably efficient recyclers of nearly any organic material,” says Crowley. “At the larva stage, they are singularly focused on consuming as much material as possible. And they are very adaptive at this task. They aren’t picky eaters!” 

On this sunny-but-cold morning, Crowley wears dark sunglasses and a pristine trucker’s hat over his shoulder-length brown hair. He has the look and temperament of a relaxed but excited (let’s call it “stoked”) cold-weather surfer. But when he talks about soil, agriculture, and larva, he speaks with the confidence and clarity of a tech CEO. “We believe our system if widely implemented, will make significant improvements to the world’s environment,” Crowley continues as he walks on the gravel path toward his new facility. “But even though we are solving an environmental problem, we are mostly making an economic pitch. Our system, we believe, can add enormous value while eliminating sizable costs.”


As we stand inside the metal barn Chapul Farms will use for research and development, Crowley and Severson explain the system by which they will turn black soldier fly larva loose on the world’s organic waste.Here is the simplified version:

  • A farm, food processor, or municipality has organic material. For instance, a food processor has tons (literal tons!) of beet skins they would normally pay to be put in a landfill.
  • Instead of a landfill, the beet skins are sent to a Chapul Farms facility and put on trays with black soldier fly larvae.
  • The larvae eat, eat, eat, and eat some more.
  • At the end of the larval stage, the larvae have finished eating and all that is left is the fat and protein-rich larva and their nutrient-dense excrement, known as frass.
  • Both the protein and the frass are valuable products that can be sold or recycled directly back into a farm operation. Today, larva protein is being used by pet food manufacturers, fish farm operators, and others. During the current fertilizer shortage, frass is a viable alternative or supplement for growers.

“Just to understand the scale,” Crowley explains, “just one acre of land used to raise BSFL can produce more than 130,000 pounds of protein every year, several orders of magnitude greater than the yield of cattle which is about forty pounds and soybeans which is only about 950 pounds.” | sedcor.comThis blog was written by SEDCOR's team with the help of Chapul Farms
