BIOMASS FROM CROP RESIDUES: COST AND SUPPLY ESTIMATES AgEcon
Gallagher, Paul W.; Dikeman, Mark; Fritz, John; Wailes, Eric J.; Gauthier, Wayne M.; Shapouri, Hosein.
The supply of harvested crop residues as a feed stock for energy products is estimated in this report. The estimates account for economic and environmental factors governing residue supply. The supply results span major agricultural crops in four distinct cropping regions of the United States, taking into account local variation in cost-determining factors such as residue yield, geographic density of residues, and competition for livestock feed use.
Tipo: Report Palavras-chave: Crop residues; Harvested residue; Residue yield; Supply estimates; Soil quality; Cropping regions; Feedstock; Biomass technologies; Reduced tillage; Forage; Crop Production/Industries; Resource /Energy Economics and Policy.

Choice of optimum feedstock portfolio for a cellulosic ethanol plant – A dynamic linear programming solution AgEcon
Kumarappan, Subbu; Ivanic, Rasto.
When the lignocellulosic biofuels industry reaches maturity and many types of biomass sources become economically viable, management of multiple feedstock supplies – that vary in their yields, density (tons per unit area), harvest window, storage and seasonal costs, storage losses, transport distance to the production plant – will become increasingly important for the success of individual enterprises. The manager’s feedstock procurement problem is modeled as a multi-period sequence problem to account for dynamic management over time. The case is illustrated with a hypothetical 53 million annual US gallon cellulosic ethanol plant located in south west Kansas that requires approximately 700,000 metric dry tons of biomass. The problem is framed over 40...

Impact and competitiveness of EU biofuel market – First view of the prices of biofuel market in relation to the global players AgEcon
Liu, Xing.
The goal of this study is to investigate the price relationship of EU biofuel market with other main markets in both horizontal level and vertical level. We first carry out Granger causality between ethanol price of EU, USA and Brazil. Secondly, we use vecto error cointegration Mechnism (VECM) to test the relationship between three selected vegetable oil prices in EU to see the competive potential of EU rapeseed oil compared with imported crude palm oil and soybean oil as the feedstock of biodiesel. Evidence shows that there is a unidirectional Granger causation from both USA and Brazil to EU market. USA price of ethanol is the most influential among the three price series, and EU has the least influence on the contrary. It indicates that it is very...

Implied Objectives of U.S. Biofuel Subsidies AgEcon
Rubin, Ofir D.; Carriquiry, Miguel A.; Hayes, Dermot J..
Biofuel subsidies in the United States have been justified on the following grounds: energy independence, a reduction in greenhouse gas emissions, improvements in rural development related to biofuel plants, and farm income support. The 2007 energy act emphasizes the first two objectives. In this study, we quantify the costs and benefits that different biofuels provide. We consider the first two objectives separately and show that each can be achieved with a lower social cost than that of the current policy. Then, we show that there is no evidence to disprove that the primary objective of biofuel policy is to support farm income. Current policy favors corn production and the construction of corn-based ethanol plants. We find that favoring corn happens to...

Land Allocation Effects of the Global Ethanol Surge: Predictions from the International FAPRI Model AgEcon
Fabiosa, Jacinto F.; Beghin, John C.; Dong, Fengxia; Elobeid, Amani E.; Tokgoz, Simla; Yu, Tun-Hsiang (Edward).
We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China,...

Production Profitability of Ethanol from Alternative Feedstocks in the Texas Panhandle AgEcon
Almas, Lal K.; Lust, David G.; Brooks, Kathleen R.; Girase, J.R..
The potential of three feedstocks: grain sorghum, sweet sorghum, and switchgrass for ethanol production in the top 26 counties of the Texas Panhandle Region is analyzed using yield and production costs of feedstock, processing cost of feedstock, final demand for ethanol, farm to wholesale marketing margin, and the derived demand price of feedstock. The calculated economic returns per acre of grain sorghum, sweet sorghum, and switchgrass are -$45.37, -$410.19, and -$150.17 respectively under irrigated condition and -$38.25, -$145.09, and -$29.04 respectively under dryland condition. The evaluation in this study demonstrates that ethanol production from grain sorghum, sweet sorghum, and switchgrass in the Texas Panhandle Region is not economically...

The Economics Of Growing And Delivering Cellulosic Feedstocks In The Beaumont, Texas Area AgEcon
Fumasi, Roland J.; Richardson, James W.; Outlaw, Joe L..
We estimate the contract prices that must be paid to grow cellulosic energy crops, and the costs of harvesting and transporting those crops in the Beaumont, TX area. Results indicate that the delivered price would range between $54 and $101 per ton of dry matter depending on the specific crop.

The Growth and Direction of the Biodiesel Industry in the United States AgEcon
Paulson, Nicholas D.; Ginder, Roger G..
The biodiesel industry in the United States has realized significant growth over the past decade through large increases in annual production and production capacity and a transition from smaller batch plants to larger-scale continuous producers. The larger, continuous-flow plants provide operating cost advantages over the smaller batch plants through their ability to capture co-products and reuse certain components in the production process. This paper uses a simple capital budgeting model developed by the authors along with production data supplied by industry sources to estimate production costs, return-on-investment levels, and break-even conditions for two common plant sizes (30 and 60 million gallon annual capacities) over a range of biodiesel and...
