DIGEST P3 is an enzyme complex produced by the breakdown of organic matter through a process called solid state fermentation, with production similar to that of yeast fermentation. Since Alltech has nearly 40 years' experience in the fermentation of yeast for both the animal health and brewing industries, biogas fermentation is a logical next chapter for the company. Through mastery of solid state fermentation techniques, Alltech can produce enzymes economically and pass this cost savings along to customers.

“This is exciting. This is why I love what I do,” said Dr. Pearse Lyons, founder and president of Alltech. “We have taken our expertise and decades of knowledge in fermentation and applied them to the development of DIGEST P3. Remember, efficiency on the farm is what we are experts in. Alltech is all about adding value and efficiency and bringing sustainable solutions to market. Dealing with waste, while at the same time producing renewable energy, is simply another way we are using innovative and ground-breaking technologies to solve our customers' issues.”

DIGEST P3 works with methane-generating microflora to help break down feedstock components previously inaccessible through digestion. This enhanced feed breakdown allows for more readily available energy and protein for the microflora, resulting in additional biogas volumes from the same amount of feed input. DIGEST P3 allows for flexibility in feedstock formulation through the inclusion of byproducts and alternative raw materials.

“We are working with customers to optimise the flexibility offered by this technology,” said Niall Brennan, biogas project manager at Alltech. “We are seeing some customers reduce their feedstock inputs and maintain their gas outputs. It is very encouraging to see the range of benefits DIGEST P3 offers Alltech customers.”

Alltech has just completed a research trial with Harper Adams University in England to identify optimum performance-enhancing additives. The trial was run utilising DIGEST P3 in commercial plants across Europe. In the trial, DIGEST P3's additional feed breakdown led to increased biogas production, reduced feed costs, reduced power consumption and uplifts in operating profit.

“Since implementing DIGEST P3, many of our customers have witnessed significant improvement in substrate efficiency,” said Brennan. “This allows our customers to decrease the amount of substrates they input each day, yet maintain a consistent energy output.”
