Fate And Transport Of Nanopesticides In Agricultural Field Plots In Central Kentucky, William D. Rud
Fate And Transport Of Nanopesticides In Agricultural Field Plots In Central Kentucky, William D. Rud
Theses and Dissertations--Biosystems and Agricultural Engineering
Due to a growing world population, pesticide applications are necessary part to increasing agricultural production on the same arable land, but this has created environmental contamination, human toxicity, and endangerment to non-target species (i.e, honeybees, monarch butterflies) from bulk pesticide application. Nanoengineered particles or ENP are a potential solution with increased efficiency, longer duration, and enhanced stability of pesticides due to their unique formulations at smaller sizes. However, the potential long-term impact to agroecosystems is still unknown. Therefore, the goal of this project was to evaluate the fate, transport, impact, and persistence of two commercially available nanopesticides (copper hydroxide and …
Life Cycle Assessment Of Air Classification As A Sulfur Mitigation Technology In Pine Residue Feedstocks, Ashlee Edmonson
Life Cycle Assessment Of Air Classification As A Sulfur Mitigation Technology In Pine Residue Feedstocks, Ashlee Edmonson
Theses and Dissertations--Biosystems and Agricultural Engineering
Sulfur accumulation during biofuel production is pollutive, toxic to conversion catalysts, and causes the premature breakdown of processing equipment. Air classification is an effective preprocessing technology for ash and sulfur removal from biomass feedstocks. A life cycle assessment (LCA) sought to understand the environmental impacts of implementing air classification as a sulfur-mitigation technique for pine residues. Energy demand and material balance for preprocessing were simulated using SimaPro and the Argonne National Laboratory’s GREET model, specifically focusing on comparing the global warming potential (GWP) of grid electricity versus bioelectricity scenarios. Overall, the grid electricity scenario had a GWP impact over 7 …
