Microalgae has been under careful consideration as a sustainable feedstock for renewable fuel recently due to its year round production with high energy yields per unit area, reduced need for arable land, water treatment benefits with nutrient cycling, and minimal competition with the food industry. Despite of all these advantages,...
Fossil fuels have been the main source of energy for a long period but due to growing concerns over climate change, oil depletion and energy security, the development of renewable sources of energy such as biofuels have been flourishing over the past few decades. Despite the fact that biofuels are...
Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...
Agricultural systems are inherently complex; understanding these systems requires knowledge of climatology, plant physiology, soil physics, economics, and the human psychology of the farmers themselves. Decision support tools strive to leverage existing data to help guide stakeholders towards the best policies and practices for their situation. Quantitative crop simulation models...
Background, aim and scope: The aim of this study was to perform a well-to-pump life cycle assessment (LCA) to investigate the overall net energy balance and environmental impact of bioethanol production using Tall Fescue grass straw as feedstock. The energy requirements and green house gas (GHG) emissions were compared to...
Background: During cellulosic ethanol production, cellulose hydrolysis is achieved by synergistic action of cellulase
enzyme complex consisting of multiple enzymes with different mode of actions. Enzymatic hydrolysis of cellulose is
one of the bottlenecks in the commercialization of the process due to low hydrolysis rates and high cost of
enzymes....

Understanding the interplay between energy and water is central to effective natural resource management. With enough energy it is possible to secure sufficient water, with enough water it is possible to produce nearly boundless energy. The sun is the engine which drives the availability of both these resources; nearly every...
Abstract
Current methods employed in the textile industry are unsustainable because they use an abundance of water in the dying process, and discharge the waste into the environment, causing adverse health effect on aquatic life and local communities. The technology that is in place to remove dye from textile effluents...
