A new business is coming to Prineville, and that is putting plenty of smiles on everyone. HM3 Energy is a Gresham based company that manufactures biomass briquettes to replace coal as a fuel source. HM3 President Hiroshi Morihara says the decision to open a plant in Prineville was easy: “Since we use forest waste of hog fuel, and normally the material is very wet, dense and wet, we like to have a plant very close to where the hog fuel is gathered. We like to have one plant within the 40-mile radius of the tree stock. And so Prineville was the idea location because of the large amount of private forest and also BLM forest, so we just had to locate the plant there." Morihara says once the plant is fully operational, they will employ about 70 people. He adds that the location at the railroad transfer is perfect for them. They plan to begin construction in the spring and be fully operational by spring of 2012.
