When the lignocellulosic biofuels industry reaches maturity and many types of biomass sources become economically … gallon cellulosic ethanol plant located in south west Kansas that requires approximately 700,000 metric dry tons of biomass … biomass stored for off-season. The sensitivity of feedstock costs to changes in yield patterns, harvesting and transport costs …

The revised Renewable Fuels Standard (RFS2) mandates that cellulosic biofuels be part of the liquid transportation fuel … cellulosic biomass production is typically smaller scale than conventional crop production, limited knowledge exists of the … actual costs of producing cellulosic biomass and converting it to cellulosic ethanol. Understanding of the implications of …

fertilizer application. This study develops a dynamic economic model of stover harvest that permits conceptualization and … quantification of these potential tradeoffs. We parameterize our model based on publicly available studies of soil biophysical … sensitive and negatively linked to corn prices, which means that policies favoring the use of stover for biomass may be …

stover, wheat straw, switchgrass, and/or forest residues. Our model incorporates county-level biomass supply as well as … national crop commodity demand. A solution to the model consists of county biomass prices and national crop prices. Keywords …We analyze the effects on local biomass supply, demand, and prices of co-firing requirement for existing coal …

susceptibility is now renewable and resistance could be reversed. Based on this method, it is plausible to predict that the optimal … model and introduce a real options approach originally used in financial analysis. We propose to view pest susceptibility as … ratio for released to natural pests, but then extend the model to allow for selection of a time-varying ratio. The cost of …

Extant point-nonpoint trading programs involve trades of relatively certain point source emissions reductions for … than or less than one, depending on how nonpoint source emissions uncertainties respond to trading. While this implies …
