In the Central American country of Guatemala, firewood is an important fuel source. Eighty-eight percent of households in rural areas use wood stoves and open fires to cook and heat their homes. This tradition has fundamental roots in the culture and customs of Guatemala. Unfortunately, these methods contribute to air pollution. Consequently, it also results in smoke inhalation, which causes health problems. Additionally, the massive agriculture of other crops decreases the amount of firewood available to these households, affecting the sustainability of the resource. Some communities resist changing their use of firewood due to the profound nature that firewood holds …
Biomethane Production From Distillery Wastewater, Zachary Christman
Biomethane Production From Distillery Wastewater, Zachary Christman
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Distillery wastewater treatment is a great ecological problem, for example, India produces 2.7 billion liters of alcohol that results in 40 billion liters of wastewater. However, this material can be seen as a resource since 11 million cubic meters of biogas at 60% methane could be produced in addition to cleaning the water. The distillery has two options of what to do with the biogas. The first is to use the biogas to fuel the distillery making the production plant more energy efficient and removing some of the need to buy natural gas. The other is to upgrade the biogas …
Improving The Distribution And Use Of Biogas By Conversion To Methanol, Zachary Christman
Improving The Distribution And Use Of Biogas By Conversion To Methanol, Zachary Christman
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
In this technology review, the process of turning an average biogas into methanol will be presented. The purpose is to find a better method of transporting the energy contained within biogas so that it may be used in industry as a value added product. The first step is removal of hydrogen sulfide, a corrosive chemical that can breakdown mechanical parts. The second step is carbon capture and conversion of the biogas into hydrogen. The final step is the hydrogenation of carbon dioxide into methanol using a copper catalyst and an alcohol co-catalyst.

Guide For Quantifying Fuels In The Sagebrush Steppe And Juniper Woodlands Of The Great Basin, Andrea Stebleton, Stephen Bunting
Reports
Prescribed fire is increasingly used for fuels management and ecosystem restoration. Managers and fuels specialists of the Great Basin are often required to estimate fuel loadings to predict fire behavior, recommend fuel treatments, or restore an area to its natural fire regime. Because of invasive species and woodland encroachment, there have been extensive changes in the fire regimes of sagebrush steppe over the past 150 years. After two years of pre-treatment sampling across six states of the Great Basin, the Sagebrush Steppe Treatment and Evaluation Project (SageSTEP) measured many variables including vegetation, soils, hydrology, wildlife, and fuels. These data will …
