Healthy Economies/Healthy Environment (Iowa Program): DDG Fuel Pellets a GIVF Project in Cooperation with LDJ Industries, Pella, IA

Situation: 

This project evolved out of a request to assist an entrepreneur in the development of a bio-based composite-material formulation for two extruded product applications.  It is in cooperation with and with matching support from the Iowa Area Development Group (IADG), West Des Moines, IA., and in partnership with LDJ Manufacturing, Pella, IA.  LDJ believes that the new composite-pellet formulation will have more consistent combustion properties, lower ash production and similar to less emissions than currently prevalent high-sugar corn fuel.  Additionally, the new extruded fuel will be a value-added agricultural product that combines underutilized, waste-stream-type materials from ethanol production, wood-product manufacturing and perhaps field-waste stovers.  LDJ has established national marketing through large chain home-improvement stores.  Prototype and pre-production development is being undertaken with the assistance of the probably manufacturer for the product, Waterloo Mills, Waterloo, IA; and processing-equipment manufacturer Landers Machinery, Ft. Worth, TX.

Objective:

Bio-based composite-material formulation for two fuel-pellet product applications

Activities/Output: 

This project has a number of significant accomplishments that include:


Impact/Outcomes: 

Ag Pellet Energy is now focusing on their 100% DDG Pellet to serve both the fuel and feed markets; with the fuel market changing from home and light-industrial application to large-scale power co-generation systems.  A DDG pelletization system could have significant positive impact on the DDG transportation stem related to animal feed, as well as large-scale power-generation co-firing systems.

Recently, LDJ Industries, Pella, has experienced an ash build-up problem with their automatic-feed burner system in their residential light-industrial stove units.  Based on testing lab data, this problem was unforeseen and deemed unlikely.  However, they currently are considering a redesign of their burner system as well as simply abandoning the DDG-pellet product for the residential light-industrial stove application.  The ISU Value-added Agriculture Project is assisting LDJ in this effort by identifying ISU research partners and preparing a 2007-2008 Iowa Energy Center Grant to fund the effort.
