Última Greenhouse Gas Impacts of Ethanol from Iowa Corn: Life Cycle Analysis versus System-wide Accounting AgEcon Feng, Hongli; Rubin, Ofir D.; Babcock, Bruce A.. Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts including land use changes that have important implications on GHGs. Thus, an alternative accounting system that goes beyond LCA is needed. In this paper, we contribute to the literature by laying out the basics of a system-wide accounting (SWA) method that takes into account all potential changes in GHGs resulting from biofuel expansion. We applied both LCA and SWA to assess the GHG impacts of ethanol based on Iowa corn. Growing corn in rotation with soybeans generated 35% less GHG emissions than growing corn after corn. Based on average corn production,...

Ano: 2008 URL: http://purl.umn.edu/6503 Ethanol and a Changing Agricultural Landscape AgEcon Malcolm, Scott A.; Aillery, Marcel P.; Weinberg, Marca. The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuel in the United States. Until advanced technologies become commercially viable, meeting these targets will increase demand for traditional agricultural commodities used to produce ethanol, resulting in land-use, production, and price changes throughout the farm sector. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional agricultural production and the environment. Meeting EISA targets for ethanol production is estimated to expand U.S. cropped acreage by nearly 5 million acres by 2015, an increase of 1.6 percent over what would otherwise be expected. Much of the growth comes from corn acreage, which...

Ano: 2009 URL: http://purl.umn.edu/55671 Economic and Marketing Efficiency Among Corn Ethanol Plants AgEcon Sesmero, Juan P.; Perrik, Richard K.; Fulginiti, Lilyan E.. In the corn ethanol industry, the ability of plants to obtain favorable prices through marketing decisions is considered important for their overall economic performance. Based on a panel of surveyed of ethanol plants we extend data envelopment analysis (DEA) to decompose the economic efficiency of plants into conventional sources (technical and allocative efficiency) and a new component we call marketing efficiency. The latter measure allows us to evaluate plants’ ability to contract favorable prices of corn and ethanol relative to spot market prices and its implications for their overall economic performance. Results show that plants are very efficient from a technical point of view. Dispersion in overall economic performance observed across units is...

Ano: 2011 URL: http://purl.umn.edu/101001 Economic and Marketing Efficiency Among Corn Ethanol Plants AgEcon Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E.. We extend data envelopment analysis (DEA) to decompose the economic efficiency of a sample of ethanol plants into internal (technical and allocative) and boundary (marketing) sources. This decomposition allows us to evaluate the channels through which different plant characteristics affect plant performance. Results show that plants are very efficient from a technical point of view. Plants with higher production volumes seem to perform better not because of economies of scale but because they can secure more favorable prices (higher marketing efficiency) and execute production plans accordingly (higher allocative efficiency). This may rationalize the increase in the size of the average plant observed in the industry in recent years despite evidence of...

Ano: 2011 URL: http://purl.umn.edu/100709 Market Power in the Corn Sector: How Does It Affect the Impacts of the Ethanol Subsidy? AgEcon Saitone, Tina L.; Sexton, Richard J.; Sexton, Steven E.. Market power is discussed in debates about subsidies for ethanol production. The structural conditions in the corn industry create a case for concerns about market power. We develop an analytical model for determining the production and price impacts and the distribution of benefits from the U.S ethanol subsidy when upstream sellers in the seed sector and downstream buyers in the processing sector may exercise market power. Results demonstrate that the impacts on prices and output are probably limited. Distribution impacts are much greater. Seed producers and corn processors with market power capture relatively large shares of subsidy benefits.

Ano: 2008 URL: http://purl.umn.edu/42457 CELLULOSIC BIOFUELS ANALYSIS: ECONOMIC ANALYSIS OF ALTERNATIVE TECHNOLOGIES AgEcon Rismiller, Craig W.; Tyner, Wallace E.. The passage of U.S. laws mandating and subsidizing advanced cellulosic biofuels may spur the development of a commercial cellulosic biofuels industry. However, a cellulosic industry will only develop if the overall economics including government incentives render investment in the sector attractive to private investors. This study compares the profitability of three biofuel production types: grain based ethanol, cellulosic biochemical ethanol, and cellulosic thermochemical biofuels. In order to compare the current profitability of each of the production types, the Biofuels Comparison Model (BCM) was developed. The BCM is a spreadsheet model that estimates the net present value (NPV) for each production type given input and output prices, technical,...

Ano: 2009 URL: http://purl.umn.edu/53583 Biofuels: Political/Economic Boondoggle or Energy Salvation for Western States? AgEcon Young, Douglas L.. Nearly all western states lack comparative advantages for producing corn for ethanol and oilseeds for biodiesel. Despite this disadvantage, most western states have legislated incentives for production of biofuels. Unfavorable changes in price relationships, high transportation costs for imported feedstocks, and tight credit markets in 2008 and 2009 led to bankruptcies and plant closures at a disproportionate rate in the western biofuel industry. Policy makers in western states are advised to fund research and development for bioenergy and biofuel feedstocks in which they have a comparative advantage. These include forestry by-products, food processing and crop residues, and livestock wastes.

Corassa,Anderson; Lautert,Iziz Paula Anhõn da Silva; Pina,Douglas dos Santos; Kiefer,Charles; Ton,Ana Paula Silva; Komiyama,Claudia Marie; Amorim,Alessandro Borges; Teixeira,Alexandre de Oliveira. ABSTRACT The objective of this study was to determine the digestibility coefficient (DC) of nutrients and the digestible energy (DE), and metabolizable energy (ME) values of distillers dried grains with solubles (DDGS) produced in Brazil by different methods. Eight barrows with 23.3±4.1 kg were housed in metabolic cages in a randomized block design and fed diets containing 0, 200, 400, and 600 g kg–1 of corn DDGS. We determined the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF), and gross energy (GE) by the total collection (TC) and chromium oxide marker (Cr) methods. Distillers dried grains with solubles provided the respective DM, OM, CP, EE, MM, NDF, and...
