Available in PDF, EPUB and Kindle. Book excerpt: Landfilling is the most popular waste disposal system worldwide; however, with increasing scarcity of materials, increases in land values, and the presence of non-engineered landfill sites in both the developing and developed world, landfill mining has been the recipient of special interest in today's waste management practices. Therefore, the motivation of the current study was to evaluate the energy potential of mined landfill waste and develop a statistically significant mathematical model to predict its energy potential (calorific value). The current study was conducted by using the municipal solid waste (MSW) samples collected from the City of Denton landfill and the City of Irving landfill Texas. Mined waste was collected from conventional cell (cell 0) and ELR operated cell (cell 2) from City of Denton Landfill, and the calorific value of the collected MSW was investigated, using an oxygen bomb calorimeter. The fine/degraded fraction made up 48% of the mined waste at the City of Denton landfill. The average calorific value of mined waste was found to be 3586.97 Btu/lb. The calorific value was also determined for fresh MSW collected from the working phase of the landfill. Based on the results, 52% of the energy value is still available in the mined waste compared with the energy potential of fresh waste. Different parameters, such as depth, landfill operation, moisture content, volatile solid, age of waste, precipitation, and fine fraction were analyzed to understand the behavior of mined solid waste. It was observed that the fine fraction had a decreasing trend, and the volatile solid had an increasing trend with the increase of calorific value. Moisture content and depth of the landfill did not exhibit any significant correlation with the calorific value. Based on the degradation nature of the solid waste components, a universal energy index, based on the composition of the waste, was introduced and found to be a very good predictor the for calorific value of MSW. Proximate analysis (Volatile solid determination) and elemental analysis 2343 determined by a muffle furnace and an elemental analyzer, respectively. Carbon was found to be the most significant element for energy value. Three simple linear regression (SLR) models, based on three different analyses (physical composition, proximate analysis, and elemental analysis), were developed to predict calorific value, using the statistical tool R. The physical model, which used the energy index, was validated with mined solid waste collected from the City of Irving landfill, and showed excellent agreement between the predicted calorific value and the measured calorific value of the MSW collected from the landfills. The model-based elemental analysis was in good agreement with the experimental values found in literature. Overall, this study will enhance the understanding of the physical characteristics and energy potential of landfill mined waste and will provide two universal mathematical models for better predictions of calorific value from any waste composition.

Book excerpt: Historically landfills have been seen as the ultimate solution for storing waste at minimum cost. But, now it is a well-known fact that these deposits have numerous implications such as long term methane emissions, local pollution and many space-related issues etc. In most parts of the world, however, landfilling is the most common method to dispose waste. Even developed countries with recycling and waste treatment facilities have been no exception in landfilling. Therefore over the years, several old and operating landfills have been accumulated with an enormous amount of obsolete materials and products. To address such issues related to waste deposits, landfill mining has been proclaimed as an innovative strategy. Although landfill mining is a solution for a number of problems, it creates new waste by extracting waste that was previously buried. So it is important to find suitable treatment and utilization routes for different types of materials considering the economic aspects and the minimization of the re-landfilled fraction of the waste. This study focuses on the characterization and valorization potential of waste from a prospective landfill mining site. According to the USEPA's (United State Environmental Protection Agency) waste management hierarchy, energy recovery is better preferred than disposal into landfills. So energy potential was calculated from the mined waste and compared to the previous studies to check the feasibility of incineration. The present study was conducted by using the municipal solid waste (MSW) samples collected from the City of Irving landfill, Texas. Mined waste was collected from three different closed cells from the City of Irving landfill, and the composition was determined. It was observed that fine and degraded portion of the mined waste made up to 60%. The calorific value of the mined waste was investigated with an oxygen bomb calorimeter. For the analysis, the major contributors for energy, that are paper, plastic, textile and wood were considered. The average calorific value of the mined waste was found to be 3365.16 Btu/lb which is above the minimum calorific value (3010 Btu/lb) specified according to the feasibility study conducted by the World Bank. Also, different parameters like moisture, volatile solids, age of waste were analyzed to understand the factors that affect the energy of mined waste. The fine fraction had a negative effect on the calorific value. Overall, the study enhances the understanding of the physical characteristics and energy potential of landfilled mined waste. Major conclusions are that there is a high potential for using mined waste to produce energy and the remaining waste, which is majorly fines can be used as a cover material for landfills. Therefore, reclamation operation in this landfill can be proved to have an evident advantage.

Available in PDF, EPUB and Kindle. Book excerpt: Gasification of Waste Materials: Technologies for Generating Energy, Gas and Chemicals from MSW, Biomass, Non-recycled Plastics, Sludges and Wet Solid Wastes explores the most recent gasification technologies developing worldwide to convert waste solids to energy and synthesis gas and chemical products. The authors examine the thermodynamic aspects, accepted reaction mechanisms and kinetic constraints of using municipal solid waste (MSW), biomass, non-recycled plastics (NRP), sludges and wet solid wastes as feedstock. They identify the distinctions between pyrolysis, gasification, plasma, hydrothermal gasification, and supercritical systems. A comprehensive summary of laboratory and demonstration activities is presented, as well as field scale systems that have been in operation using solid waste streams as input, highlighting their areas of disconnect and alignment. The book also provides a summary of information on emissions from the stack, comparing them with other thermal conversion systems using similar feedstock. It then goes on to assess the areas that must be improved to ensure gasification systems become as successful as combustion systems operating on waste streams, ranging from feedstock processing to gasifier output gas clean-up, downstream system requirements and corrosion. The economics and future projections for waste gasification systems are also discussed. For its consolidation of the current technical knowledge, this text is recommended for engineering researchers, graduate students, industry professionals, municipal engineers and decision makers when planning, designing and deploying waste to energy projects, especially those using MSW as feedstock. - Provides field demonstrations of large scale systems, their results and the challenges that need to be overcome when developing commercial applications and possible solutions - Presents the most recent technologies in lab and demonstration scale - Examines the critical development needs and real life challenges for the deployment of waste to energy technologies - Provides information on the economics and sustainability of these technologies, as well as their future perspectives

This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
