Download or read book Dynamic Characteristics and Stability Analysis of Municipal Solid Waste in Bioreactor Landfills written by Mohamed Adil Haque and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioreactor landfills are operated to enhance refuse decomposition, gas production, and waste stabilization. The major aspect of bioreactor landfill operation is the recirculation of generated leachate back through the refuse mass. Due to the accelerated decomposition and settlement of solid waste, bioreactor landfills are gaining popularity as an alternative to the conventional landfill designed under Subtitle D regulations. However, recirculation of leachate or addition of water to accelerate the waste decomposition changes the biodegradation and geotechnical characteristics of waste mass. Our understanding of changes in engineering characteristics of solid waste with accelerated decomposition is limited. There is a need to understand and explain the changes in characteristics associated with stability analysis of landfills. The objective of this research is to study the changes in strength characteristics of municipal solid waste (MSW) in bioreactor landfills with time and decomposition. In order to understand the changes in strength properties of MSW in bioreactor landfills with time and decomposition an experimental program was developed. Eight small scale reactors, representative of bioreactor landfill, were built in laboratory, and samples were prepared to represent different phases of decomposition. The state of decomposition was quantified by methane yield, pH, and volatile solids. The geotechnical testing program (CD triaxial test and resonant column tests) was performed to determine shear strength and dynamic characteristics of MSW in bioreactor landfill. The test results indicated that the measured shear strength and dynamic properties of MSW are significantly affected by the degree of decomposition. The friction angle of MSW decreased from 26.7° in Phase I to 19° in Phase IV. The shear modulus increased from 2.11 MPa in Phase I to 12.56 MPa in Phase IV. The change in shear strength and dynamic properties of MSW was attributed to the breakdown in fibrous nature of solid waste particles with degradation. Based on the measured experimental results, stability analyses were conducted. The finite element program PLAXIS and limit equilibrium program STABL was used to analyze the stability of MSW in bioreactor landfills. The stability was evaluated at both under normal and those during earthquake conditions. The factor of safety estimated using PLAXIS and GSTABL under both the conditions decreased as the solid waste degraded with time. The results indicates that the stability of bioreactor landfills should be evaluated using the strength characteristics determined as a function of time and decomposition rather than using average values.

Available in PDF, EPUB and Kindle. Book excerpt: ENCYCLOPEDIA OF RENEWABLE ENERGY Written by a highly respected engineer and prolific author in the energy sector, this is the single most comprehensive, thorough, and up-to-date reference work on renewable energy. The world’s energy industry is and has always been volatile, sometimes controversial, with wild swings upward and downward. This has, historically, been mostly because most of our energy has come from fossil fuels, which is a finite source of energy. Every so often, a technology comes along, like hydrofracturing, that is a game-changer. But is it, really? Aren’t we just delaying the inevitable with these temporary price fixes The only REAL game-changer is renewable energy. For decades, renewable energy sources have been sought, developed, and studied. Sometimes wind is at the forefront, sometimes solar, and, for the last decade or so, there has been a surge in interest for biofeedstocks and biofuels. There are also the “old standbys” of nuclear and geothermal energy, which have both been around for a very long time. This groundbreaking new volume presents these topics and trends in an encyclopedic format, as a go-to reference for the engineer, scientist, student, or even layperson who works in the industry or is simply interested in the topic. Compiled by one of the world’s best-known and respected energy engineers, this is the most comprehensive and up-to-date encyclopedia of renewable energy ever written, a must-have for any library.

Available in PDF, EPUB and Kindle. Book excerpt: Petroleum-based fuels are well-established products that have served industry and consumers for more than one hundred years. However petroleum, once considered inexhaustible, is now being depleted at a rapid rate. As the amount of available petroleum decreases, the need for alternative technologies to produce liquid fuels that could potentially help prolong the liquid fuels culture and mitigate the forthcoming effects of the shortage of transportation fuels is being sought. The dynamics are now coming into place for the establishment of a synthetic fuels industry; the processes for recovery of raw materials and processing options have to change to increase the efficiency of oil production and it is up to various levels of government not only to promote the establishment of such an industry but to recognise the need for available and variable technology. This timely handbook is written to assist the reader in understanding the options that available for the production of synthetic fuel from biological sources. Each chapter contains tables of the chemical and physical properties of the fuels and fuel sources. It is essential that the properties of such materials be presented in order to assist the researcher to understand the nature of the feedstocks as well as the nature of the products. If a product cannot be employed for its hope-for-use, it is not a desirable product and must be changed accordingly. Such plans can only be made when the properties of the original product are understood. The fuels considered include conventional and unconventional fuel sources; the production and properties of fuels from biomass, crops, wood, domestic and industrial waste and landfill gas.
