This book was released on 2019 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the decreasing rate of landfilled waste due to increases in reuse and recycling, landfilling remains an enormous part of the waste industry of the United States due to population and economic growth. In addition, certain wastes are not easily recycled due to their mixed composition (i.e. a cardboard carton with a plastic lining) or their contamination (i.e. diapers). The primary goal of this research is to develop a comprehensive framework that can help and fill designers chose the best type of landfill (conventional, bioreactor, or aerobic) for a given situation based on greenhouse gas (GHG) emissions, traditional air pollutants and costs (internal and external). This study focuses on estimation of life cycle costs (LCC), appraisal of life cycle inventory (LCI) of air emissions, and estimation of external costs arising from environmental damages during disposal of solid waste into landfills. The study fills several gaps in the existing literature:  Several life cycle inventories of air pollutant and greenhouse gas emissions have been conducted to date for landfills outside the United States. Generally, the studies focus on direct emissions from landfills. Few studies include infrastructure construction or transportation of required material for construction in the analysis. Furthermore, these international studies do not necessarily apply to US conditions. Previous studies have reported useful methodologies for assessing the economic performance of landfills and implementing landfill gas-to energy (LFGtE) projects, but they have typically not considered the role of solid waste acceptance rate and the effect of cost amortization over the lifetime of landfill. In addition, a cost function for each phase of life cycle of landfill has not been provided in the context of the US. In many studies about landfill-biogas-to energy, landfill biogas collection efficiency has been assumed to be a single value rather than a temporally weighted collection efficiency depending on the stage of landfill operation. Additionally, the combination of internal combustion engines that convert biogas to electricity have been chosen arbitrarily, so that the effect of upper and lower bounds of required rate of biogas flow entering to run such engines were not taken into account. Specific objectives of the study are:1. To develop a landfill life cycle internal cost model for all types of landfills for raw materials acquisition, construction, operation, closure and post-closure phases of 3 types of landfills (conventional, bioreactor, and aerobic). 2. For the use/operation phase of landfill-gas-to-energy systems, including fugitive methane emissions escaping through landfill covers, to determine the quantities of GHG emissions, traditional air pollutants , potential electricity generation and internal costs from LFGtE implementation in conventional and bioreactor landfills and subsequent revenue from electricity sales within a 100-year time horizon. 3. To quantify greenhouse gas emissions and air pollutant emissions for all types of landfills from landfill raw materials acquisition, construction, operation and end of life. 4. To integrate environmental damage-based external costs from GHGs and air pollutants, and internal costs estimated by LCC, for the all types of landfills. To determine the LCC associated with different types of landfills, a Landfill Life Cycle Cost model (2L2C) was developed using LCC methodology and economic elements of pre-construction and construction, operation and end of life of phases of landfill to estimate costs within estimation range defined by Association for the Advancement of Cost Engineering (AACE). The range of total annual life cycle cost of a conventional landfill was found to be $25 to $43 per ton of landfilled waste based on the type of landfill and waste acceptance rate. The operational phase was responsible for the majority of the costs (40 to 50%), largely from equipment costs and, particularly for conventional landfills, from leachate treatment costs. The construction phase contributed in the range of 30% to 50%, of which the excavation costs contribute around 25-35% of the construction costs. Finally, end-of-life activities were responsible for 13 to 20% of the total annual life cycle costs, owing mainly to the final cover costs and especially post closure care for conventional landfills. To determine the quantities of GHG emissions, traditional air pollutants and potential electricity generation from conventional and bioreactor landfills during operation phase of landfill-gas-to energy ( LFGtE) system, a model was developed to incorporate environmental factors such as biogas generation, impacts of various collection efficiencies, converting the methane portion of biogas to electricity, offsetting fossil fuel based-electricity by burning recovered methane,methane oxidation through the landfill soil cover and emission inventories of biogas control devices. The average electricity production for bioreactor landfill and conventional landfill was estimated to be 4993 and 3153 MWh per million ton of waste in place. In bioreactor landfills,the annual revenue ranged from $8.50 to $24.77 per ton of waste based on acceptance rate. Also, total GHG emission in the most realistic case ranged from 168 and 371 kg CO2e per 1 t of landfilled MSW. To quantify greenhouse gas emissions and air pollutant emissions from landfill raw materials acquisition, construction, operation and end of life, the sub-stages of the construction and operational and end of life stages (including LFGtE system) of MSW landfills were identified. Using the LCI method, GHG and traditional air pollutant emissions inventories were performed for a generic "national average" landfill. The analyses revealed that construction and operation phases make up about 75% of total CO2e emissions within the entire life cycle of landfill. Manufacturing of materials for construction phase and equipment use during operational phase account for the majority of emissions to the atmosphere. To integrate environmental damage-based external costs from GHGs and air pollutants, and internal costs estimated by LCC, for the 3 types of landfills, the contributions of the emissions to external costs and internal costs over the life cycle of landfills was combined. Direct emissions from the landfilling system represented the major contributor to overall GHG emissions, whereas emissions from LCI of the landfill were determined to be responsible for nearly 2%,which is extremely low. External system costs, for a landfill with a low waste acceptance rate, did not exceed $1.35 per ton of waste. This value never went below $0.77 per ton waste for anaerobic landfill. If average LFG collection efficiency were installed in bioreactor and conventional landfills, the aerobic landfill would have more sustainable performance in terms of GHG emissions and traditional air pollutants. In the case of high LFG collection efficiency considered for bioreactor and conventional landfills, the bioreactor landfill was recognized to have the lowest total cost including Internal and external costs compared to other types of landfills.

Available in PDF, EPUB and Kindle. Book excerpt: Landfilling has been and still remains an important means of municipal solid waste management but it poses a threat to the purity of the environment, especially air. In the coming years, a radical decline in the share of landfilling in waste disposal practices should not be expected. However, this is not to say that people are powerless in the face of the emission of harmful gases into the atmosphere, the spread of bioaerosols and odors. There are many ways of preventing the negative impact of landfills or protecting the environment against such an impact. Some of these preventive and protective measures are described in Mitigation of Landfill Gas Emissions. Special attention is given to the application of anaerobic, aerobic and semi-aerobic bioreactor landfills for control of landfill gas emission. Different types of biotic systems for the oxidation of methane and trace gases, such as biocovers, biofilters, and biowindows, are also presented.

This book was released on 2012-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life is often considered to be a journey. The lifecycle of waste can similarly be considered to be a journey from the cradle (when an item becomes valueless and, usually, is placed in the dustbin) to the grave (when value is restored by creating usable material or energy; or the waste is transformed into emissions to water or air, or into inert material placed in a landfill). This preface provides a route map for the journey the reader of this book will undertake. Who? Who are the intended readers of this book? Waste managers (whether in public service or private companies) will find a holistic approach for improving the environmental quality and the economic cost of managing waste. The book contains general principles based on cutting edge experience being developed across Europe. Detailed data and a computer model will enable operations managers to develop data-based improvements to their systems. Producers oj waste will be better able to understand how their actions can influence the operation of environmentally improved waste management systems. Designers oj products and packages will be better able to understand how their design criteria can improve the compatibility of their product or package with developing, environmentally improved waste management systems. Waste data specialists (whether in laboratories, consultancies or environ mental managers of waste facilities) will see how the scope, quantity and quality of their data can be improved to help their colleagues design more effective waste management systems.

Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.

Download or read book Disposal is Not Free Fiscal Instruments to Internalize the Environmental Costs of Solid Waste written by Ms.Thornton Matheson and published by International Monetary Fund. This book was released on 2019-12-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper provides an overview of global solid waste generation, its environmental costs, and fiscal instruments that can be used to encourage waste reduction and finance proper disposal. Countries—especially island nations--struggle to manage an ever-increasing volume of solid waste, generation of which is projected to exceed 2 billion tons a year by 2025. Although solid waste management is usually relegated to subnational governments, externalities from inadequate management, which include greenhouse gas emissions and ocean plastic pollution, reach global scale. National governments thus play a critical role in creating incentives for waste minimization and ensuring adequate resources for proper waste management. This paper evaluates potential fiscal instruments to achieve these goals, particularly in developing country policy environments.
