PrairieChar’s Manure-Processing Tech Takes Prize at Agtech Showcase

Xconomy Raleigh-Durham — 

[Updated 5/18/17, 4:01 pm. See below.] Manure is an inescapable part of farming, and it can be an expensive and messy one at that. Large animal farms produce so much waste that it must be stored in tall piles or deep lagoons. If storms spill that waste or it somehow seeps into the groundwater, farmers and communities find themselves scrambling to clean it up.

Agtech startup PrairieChar aims to transform manure from a cost center into a profit stream. The Lawrence, KS-based company has developed technology that “deconstructs” manure, turning it into sterile products that have applications in the soil and fuel markets. Because manure is heavy and expensive to move, CEO Bob Herrington says the key to PrairieChar’s approach is bringing the technology to the manure pile.

“Our goal is to not move that manure more than 300 feet,” he says. “If we do, it’s not cost effective.”

PrairieChar was the winner last week of the Ag Biotech Entrepreneurial Showcase, an annual event hosted by the North Carolina Biotechnology Center that draws agtech startups from across the U.S. and around the world. PrairieChar was voted the winner for its machine, assembled near where manure is stored, that converts animal waste into two products. PrairieFood is a soil amendment that the company describes as a “super food for soil microbes.” PrairieFire is a fuel that Herrington says is comparable in energy content to sub-bituminous coal, a type of coal burned mainly in power plants and industrial operations.

The PrairieChar technology could find a ready market in North Carolina, which the National Pork Board ranks as the nation’s number two state in hog and pig inventory. Much of the waste produced by these farms is stored in large lagoons. Herrington says PrairieChar’s “wet process” works well with swine manure. He adds that the company already has orders for its product and the company has secured some commitments for a Series A round of financing targeting $5 million [Paragraph updated to clarify that the funding round is still underway].

As the showcase winner, PrairieChar was awarded a $10,000 cash prize. The company will also receive in-kind services from the accounting firm Hughes Pittman & Gupton and law firm Smith Anderson.

Second place went to another Lawrence-based company, Integrated Animal Health (IAH). The startup’s lead product is an anti-diarrheal drug for cattle. Up to 25 percent of calves can get sick from diarrhea, but farmers don’t know if the cause is viral or bacterial, says president and CEO Blake Hawley, who is also a veterinarian. IAH’s Scour Mate binds to gut toxins, regardless of the source of infection. IAH has also developed a canine version of Scour Mate.

Scour Mate was originally a treatment for dysentery in children—a small market. Hawley says IAH aims to find other overlooked human health products that have the potential to find wider use as treatments for animals. Other products that the company is developing include a repellant for fleas and ticks, and an edible heartworm medication for dogs. IAH is currently raising a $5 million round of funding to support its research and development efforts. IAH’s second-place prize was $2,500 cash.

Here’s a look at the other 10 startups that presented at the showcase:

Agribody Technologies. San Diego-based Agribody is using genome editing to boost crop yields, improve how plants hold up to environmental stresses, and lengthen the shelf life of food. The company is using the CRISPR-gene editing system to edit two genes in order to change the levels of a protein that has a role in whether cells grow and divide, or die, says Jerry Feitelson, the startup’s CEO and co-founder. The company’s technology is based on research from the University of Waterloo. The company has also licensed CRISPR gene-editing technology from Benson Hill Biosystems. Feitelson says Agribody’s long-term goals include partnering with large seed companies. In the meantime, the startup is raising $1 million in seed financing to support its research.

Applied LifeSciences & Systems. Consumer and regulatory pressures are pushing the food industry away from using antibiotics in poultry. Vaccines can reduce the need for antibiotics, but current methods can’t effectively deliver the vaccines to all chicks, says Ramin Karikpour, founder and CEO of Applied Life Sciences & Systems. Spraying vaccine misses some chicks and injecting each one manually is too labor intensive. The Raleigh, NC-based startup is developing a system that Karikpour says can effectively deliver vaccines to individual chicks. Applied Life Sciences & Systems is aiming to raise $4.1 million in a Series A round to continue its research and development work. Karikpour says he is also looking to partner with a large poultry company.

Apse. St. Louis-based Apse has developed a way to make genetic changes using a natural biological process. Apse’s approach blocks RNA, a molecule that acts as a messenger carrying genetic information. RNA interference (RNAi) can be used to block the expression of specific genes, which has potential applications in … Next Page »
