Book excerpt: Life Cycle Assessments (LCAs) are quantitative analyses of complex systems for evaluation of impacts and risk associated with management decisions. LCAs can be effective tools for determining comparative advantages of management strategies across specific impact concern. In this study, life cycle assessments of pork production management alternatives was performed. The alternative management practices included in this study were production of entire males (boars), use of pens for gestation housing, immunocastration, production without growth promoting antimicrobials, production without growth promoting and preventive antimicrobials, and production without ractopamine. These LCAs evaluated the impact of each management strategy on greenhouse gas emission (GHG), cumulative energy use, and cumulative water use compared to the common baseline. Each alternative management strategy was simulated in Pig Production Environmental Footprint (PPEF) model by varying key variables. Life cycle inventory inputs for unit process created using PPEF model were used for SimaPro V7.3 (Pre' Consultants, The Netherlands), an LCA modeling program. The functional unit for the analysis was one kilogram live weight at the farm gate. Influence of temperature on impact categories was evaluated by testing all alternate management practices at five temperature regimes. While, temperature influenced the changes to the impact categories, hypothesis testing was performed for alternative management practices for scenario at Wright County, Iowa that used typical meteorological year to control temperature inside the barn. LCAs of alternative management practices yielded a range of results. Increase in GHG emissions, cumulative energy use, and cumulative water use were observed for no growth promoting antimicrobials (1.559, 1.746, and 1.038% respectively), no growth promoting or preventive antimicrobials (17.321, 18.399, and 15.577% respectively), and removal of ractopamine (6.515, 4.867, and 7.518% respectively) scenarios. For entire males scenarios GHG emission and cumulative energy use increased by 2.092 and 3.748% but cumulative water use decreased by 2.294%. Lower GHG emissions, cumulative energy use, and cumulative water use were observed for gestation pens (0.973, 1.499, and 0.972% respectively) and immunocastration (2.385, 2.567, and 2.963% respectively) scenarios. These changes could be concluded with at least 75% confidence only for lower water consumption for entire males, decreased GHG emissions and water consumption for immunocastration, increased cumulative energy consumption for no growth promoting antimicrobials, increase in all three impact categories for no growth promoting or preventive antimicrobials, and increased GHG emissions, cumulative energy and cumulative water consumption for removal of ractopamine scenarios. A null hypothesis that changing management practices in the pork production in the US does not affect impact category metrics used for sustainability assessment was rejected using one tailed paired t-test at P

This book was released on 2021-04-01 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition towards renewable energy sources and “green” technologies for energy generation and storage is expected to mitigate the climate emergency in the coming years. However, in many cases, this progress has been hampered by our dependency on critical materials or other resources that are often processed at high environmental burdens. Yet, many studies have shown that environmental and energy issues are strictly interconnected and require a comprehensive understanding of resource management strategies and their implications. Life cycle assessment (LCA) is among the most inclusive analytical techniques to analyze sustainability benefits and trade-offs within complex systems and, in this Special Issue, it is applied to assess the mutual influences of environmental and energy dimensions. The selection of original articles, reviews, and case studies addressed covers some of the main driving applications for energy requirements and greenhouse gas emissions, including power generation, bioenergy, biorefinery, building, and transportation. An insightful perspective on the current topics and technologies, and emerging research needs, is provided. Alone or in combination with integrative methodologies, LCA can be of pivotal importance and constitute the scientific foundation on which a full system understanding can be reached.

This book was released on 2014 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intent of this study was to analyze water use across a range of regions, scales and practices of the U.S. pork industry. A Life Cycle Assessment of water use within the pork supply chain was performed. Cumulative water use was the environmental impact category used in the LCA to evaluate the impacts of pork production processes throughout the pork supply chain. The functional unit for the analysis was the volume of water required to produce one kilogram of swine (live weight) at the farm gate. A comprehensive literature review was used to design and propagate algorithms for the National Pork Board Pig Production Environmental Footprint Calculator (version 2.0). The outputs from the calculator were used to generate lifecycle inventory inputs for unit processes in SimaPro (Pre' Consultants, The Netherlands), an LCA modeling program. The LCA method was then used to assess the water footprint for swine production from cradle to farm gate production scenarios. There were 240 different scenarios analyzed that were a combination of ten regions, three production strategies and three scales. The grow/finish barn phase of the on farm water footprint requires approximately five times as much water as the sow and nursery barns irrespective of the barn infrastructure. Water used to irrigate swine feed crops contributed 89% of the total cradle to farm gate footprint. Since all 240 scenarios were analyzed with the same ration inputs, the final footprints did not vary drastically between scenarios. There were small deviations such as tunnel ventilated production systems consistently required more water than hoop barns due to cooling systems in warmer regions. Smaller scale operations consistently had higher water footprints due to economy of scale, although the footprint differences between scales were marginal. Regarding the water use that occurred on the swine farm, drinking water was by far the most significant contributor to the footprint (81%). Production strategies, production scale and region of production were all statistically significant (p

This book was released on 2010-09-30 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental life cycle assessment is often thought of as cradle to grave and therefore as the most complete accounting of the environmental costs and benefits of a product or service. However, as anyone who has done an environmental life cycle assessment knows, existing tools have many problems: data is difficult to assemble and life cycle studies take months of effort. A truly comprehensive analysis is prohibitive, so analysts are often forced to simply ignore many facets of life cycle impacts. But the focus on one aspect of a product or service can result in misleading indications if that aspect is benign while other aspects pollute or are otherwise unsustainable. This book summarizes the EIO-LCA method, explains its use in relation to other life cycle assessment models, and provides sample applications and extensions of the model into novel areas. A final chapter explains the free, easy-to-use software tool available on a companion website. (www.eiolca.net) The software tool provides a wealth of data, summarizing the current U.S. economy in 500 sectors with information on energy and materials use, pollution and greenhouse gas discharges, and other attributes like associated occupational deaths and injuries. The joint project of twelve faculty members and over 20 students working together over the past ten years at the Green Design Institute of Carnegie Mellon University, the EIO-LCA has been applied to a wide range of products and services. It will prove useful for research, industry, and in economics, engineering, or interdisciplinary classes in green design.
