This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane digesters -- biogas recovery systems that use methane from manure to generate electricity -- have not been widely adopted in the United States because costs have exceeded benefits to operators. Burning methane in a digester reduces greenhouse gas emissions from manure management. A policy or program that pays producers for these emission reductions -- through a carbon offset market or directly with payments -- could increase the number of livestock producers who would profit from adopting a methane digester. We developed an economic model that illustrates how dairy and hog operation size, location, and manure management methods, along with electricity and carbon prices, could influence methane digester profits. The model shows that a relatively moderate increase in the price of carbon could induce significantly more dairy and hog operations, particularly large ones, to adopt a methane digester, thereby substantially lowering emissions of greenhouse gases.

Download or read book Cost benefit Analysis of the Greenhouse Gases Mitigation Options in Livestock written by Cindy Schoumacher and published by . This book was released on 2012 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since many years, the need to abate the greenhouse gases emissions appeared to be more and more obvious for the scientist community, politics, economists and society. While contributing to about 12% of the world anthropogenic emissions (2005), agriculture has an important role to play in the fight against climate change and pollutions. In particular, manure would produce 7% of the world non-CO2 anthropogenic emissions. Thus, it represents a source of agricultural pollution on which many studies have been done to find solutions to these emissions. Anaerobic digesters could be one of the best options. This study will create a simplified economic model to build the Mitigation Abatement Cost curves for the anaerobic digesters in the USA and Vietnam. They enable us to do a cost-effective analysis of the different digesters while classifying them in an ascending order of break-even prices and associating these prices to an amount of gas reduced. They finally give the potential of the American and Vietnamese digesters to reduce the emissions from manure. This study shows the existence of some cost-effective technologies, presents the heterogeneity of the results according to the farms characteristics (such as the localization and the farm size), and proves the importance of the assumptions and data used to build such a model (thanks to a sensitivity analysis of some parameters such as the implied adoption rate of each digester in a country, the scale effects, the discount rate, the "adoption rate").
Download or read book Potential for Methane Digesters on U S Dairy Farms written by Dana L. Brooks and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane digesters are a potential investment for a dairy farm. A digester can lower greenhouse gas emissions, manage manure waste, generate energy, provide fertilizer and recycle bedding. The AgSTAR project of the Environment Protection Agency describes anaerobic digesters as a solution to a problem dairy farmers have always had to solve but that has become more acute with the innovation of larger scale, confined animal feeding operations developed in response to the growing food demands of the world's larger and more prosperous middle class population -- what to do with cow manure. Digesters take cow manure and convert it into energy while also eliminating manure odor. Energy is the primary economic benefit of a digester. A dairy farmer can use the electricity or gas generated from the digester to fuel the energy needs of the farm. Selling gas or electricity on the market is a revenue source that largely determines the level of profit from investing in a digester. This thesis will explore the four economic factors required to make anaerobic digesters a viable economic investment for a 1,500 head cow herd in the United States. It is imperative that farmers are able to obtain a return on the investment as soon as possible as many do not have the capital to invest in a nearly $1 million project. Congress may need to provide additional incentives for farmers and utility companies to take waste and process to energy. The future for methane digesters looks profitable when energy and carbon markets are available and allowed to trade competitively. The federal government may consider focusing on incentives for the utility companies' infrastructure to make purchases of renewable energy from a digester more economically attractive and efficient. Today, an obstacle for increasing the number of digesters in the United States is the cost associated with moving the energy from the digester and into the national natural gas to grid. Natural gas companies may need to be compensated for that expense plus the potential difficulties of dealing with multiple suppliers or digester owners. Electricity companies have a grid in place to power rural and urban communities. They have spent billions of dollars and decades to establish efficient routing of power to residents and businesses. Manure digesters are mostly located in rural areas that would also require an investment in infrastructure to move the energy from the digester to the power grid. Mandating net-metering would require energy companies to purchase renewable energy, but consumers may see an increase in their cost. Therefore, the answer to increasing the number of manure digesters in the United States may be to direct the incentives to utility companies to invest in expanding infrastructure rather than increasing digester owner subsidies. Although, the REAP grants are helpful for assisting farmers with startup installation costs, there may not be a need to increase that subsidy in the next farm bill if an energy bill includes incentives for energy companies to purchase renewable energy from digesters.

This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.
Download or read book Manure Use for Fertilizer and for Energy written by James M. MacDonald and published by DIANE Publishing. This book was released on 2010 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.
