POET's Technology Advantage


POET’s technology advantage. POET is constantly developing new ways to make ethanol production more efficient and new bio-based products. Some notable technology developments at POET include:


BPX


BPX Our patented raw starch hydrolysis process, named BPX, converts starch to sugar with a proprietary blend of enzymes, while other ethanol producers use a jet cooker to break down starch with heat. BPX reduces energy use in the plant by 8 to 15% and increases yield by 0.10 to 0.15 gallons per bushel. After years of development, we brought the process to commercial scale production in 2004 and it is now deployed in 24 of our biorefineries. The EPA recognizes BPX as an advanced corn ethanol technology under its RFS2 regulations.


Total Water Recovery


Our patent-pending Total Water Recovery system continuously filters and treats water until it is of usable quality. This system essentially eliminates liquid discharge from the biorefineries in our network, except for steam and water present in our DDGS. Because we recycle water used in the production of ethanol, the biorefineries in our network on average require less than three gallons of water per gallon of ethanol.


Antibiotic-Free DDGS


POET has developed an ethanol production process that does not require antibiotics, which enables us to offer certified antibiotic-free products.


Load Toad


Load Toad Our patented and trademarked Load Toad technology evenly distributes dried distillers grains onto rail cars, which increases the amount of DDGS we can load into each car by 3.5 to 5.6 additional tons, thereby reducing freight cost. In 2010, we installed our Load Toad technology at 20 of the biorefineries in our network. We also are able to license this technology to non-ethanol producing companies that load corn starch, pellets or similar-handling products.
