Barriers to Developing Sustainable Supply of Lignocellulosic Feedstock for Production of Biofuels
Thirteen unique storage conditions of baled corn stover biomass were studied to examine the impact of bale type, baling technique, and storage practice on moisture control and product degradation over time. Square bales were found to outperform round bales in terms of moisture regulation and physical stability across all treatment types and at all sampling times. Within square bales, the control of moisture content in short term storage (3 months) is comparable between tarped and untarped stacks. In long term storage (9 months), bale wrapping outperforms both tarped and open stacks. In terms of overall moisture control, stack tarping allows moisture to leave initially wet bales, but allows dry bales to gain large amounts of moisture over time. Initial moisture content was found to drive self-heating and depend heavily on storage practice. While differences in dry matter loss over time are unclear, bale stability was lowest in the untarped stack, moderate in tarped stacks, and greatest in wrapped stacks. Overall, bale storage has been shown to be a dynamic system which requires special judgment to be made depending on the state of inbound material and the desired storage duration.
