The Economics And Logistics Of The Dual Harvest Of Grain And Biomass In A Single-Pass, Matthew T. Wold
The Economics And Logistics Of The Dual Harvest Of Grain And Biomass In A Single-Pass, Matthew T. Wold
Department of Biological Systems Engineering: Dissertations and Theses
Significant interest has developed in using cellulosic resources, especially crop residues, to create biofuels. Collecting these residues in a single-pass of the harvester across the field has the potential to be a low cost option. Two models have been developed; the first characterizes the in-field logistics of single-pass crop residue collection, the second the economics. These models allow the user to easily examine a wide variety of both grain-only and single-pass residue collection harvest cases. A variety of possible residue collection cases have been examined, and their effects both on harvester field capacity and harvest cost compared to grain-only harvest …
Economic And Environmental Sustainability Of Using Bio-Fuels For Small Nebraska Greenhouses, David M. Mabie
Economic And Environmental Sustainability Of Using Bio-Fuels For Small Nebraska Greenhouses, David M. Mabie
Department of Environmental Engineering: Theses and Student Research
The primary goal of this paper was to increase profitability in Nebraska greenhouses by using biomass fuels for heating instead of propane. Several different fuels were tested, including whole shelled corn, dry distiller’s grains pelletized, wood pellets and blends between each biomass. The main fuel focus was on whole shelled corn. Bomb calorimetry tests were performed on biomass fuels and their respective ashes. Several furnace and heat exchanger efficiency tests were performed, with cost effectiveness analysis for each fuel type. Emissions data was also collected for each fuel on carbon monoxide, carbon dioxide, nitrous oxides, sulfuric oxides, and particulate matter. …
