Mobile Pelletizer Production(ST10752-1)

Lower Hudson - Long Island RC & DC Counc


There is an increasing interest in the development of alternate fuels to replace traditional, non-renewable fossil fuels for heating applications. Grass pellets have the potential to be an excellent alternative for several reasons. High yields of grass crops can be realized on marginal farm land that would otherwise go unused, and, fortunately, the grasses require minimal maintenance and fertilizer. They have a fuel input-to- output ratio as high as 10 to 15, which is several times higher the best achieved ratios for ethanol and biodiesel. The agricultural community in New York State is starting to show great interest in the crop, as there is ample unused marginal farm land. There is also increased interest as there is potential to create a sustainable, local economic model, encompassing a significant portion of the grasses’ lifecycle from cultivation to consumption. The Contractor will use the mobile pelletizer developed under PO 9953.

Project Description

The Contractor will perform an initial background review on emissions and materials compatibility. The Contractor will develop economic models to determine the best operations protocols, and will investigate and optimize the various sub processes involved with grass pelletization. A few examples of such processes are grinding times, pellet size, and cooling times. Once optimized, the Contractor will develop an operations manual and demonstrate the pelletizer at various trade shows, as the ultimate goal is information sharing, leading to widespread use of the pelletizers. The pelletizer and manual will be non-proprietary to facilitate widespread adoption.


Benefits include reduced fossil fuel consumption and sustainable, local industry, and economic development.
