Farmers and landowners want to lower fuel and feed costs, explore feed and fertilizer co-products, be more self-sufficient, and rely less of fossil fuels. Biomass grass crops can be established on marginal lands and processed as a fuel replacement for heating oil or propane, or as an addition to wood chips or pellets.There are four main models for implementing grass energy on a farm. The models differ from each other in where the grass is grown and processed. Two are closed-loop models, in which the grass is grown and processed on-site, and the others are variations of processing the grass in a central facility and distributing production of the feedstock among regional farms.
Grass fuel can occur as bales that get chopped just prior to combustion or densified fuels like pellets, cubes, or briquettes. The densified fuels are made using machinery that applies high temperature and pressure to the chopped feedstock, pressing it into the desired shape. A series of dies and knives are responsible for cutting the fuel into its desired shape. Each of the four grass energy models, described below, produce one or two of these types of fuel.
