This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...

7 Abstract 8 An existing materials flow model is adapted (using ExcelTM and AMBERTM model platforms) 9 to account for waste and hidden material flows within a domestic environment. Supported by 10 national waste data, the implications of legislative change, domestic resource depletion and 11 waste technology advances are explored. The revised methodology offers additional 12 functionality for e...

population growth and consequently increasing waste are made concern about resources degradation. thus, municipal solid waste management (mswm) becomes a priority for experts in recent decades. to apply new technology in mswm and engineering methods is the base of determining strategies, health and environmental policies. mswm is included some factors such as waste generation, collection, trans...

Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste with inoculating horse dung by 15% of the total wet weight, at the temperature of 37o</su...

wear is a complicated phenomenon caused by the relative movement of two contacting surfaces compressed together by a normal force. prediction of the wear, in most cases, requires various experiments and microstructural characterization of the contacting surfaces. mathematical models based on physical concepts could provide considerable help in understanding the physical behavior and hence the p...

Food waste from households contributes the greatest proportion to total food waste in developed countries. Therefore, food waste reduction requires an understanding of the socio-economic (contextual and behavioural) factors that lead to its generation within the household. Addressing such a complex subject calls for sound methodological approaches that until now have been conditioned by the lar...

Department of Environmental Biotechnology, School of Environmental Sciences, Bharathidasan University, Trichy620 024 Mail id: [email protected] ABSTRACT: The increasing waste generation rate, high collection cost and dwindling financial resources are the major problems faced by most of the developing countries for efficient solid waste management. In some cities, the organic wastes (Market...

States are often seen as policy laboratories where innovations are tried that may later be adopted by other states or the federal government. Engendering such experiments may, however, promote spillovers on other states. We analyze several of New York State's policy initiatives from the 1980s that were intended to influence the selection of waste management technologies by hazardous waste gener...

This paper represents a detailed assessment on raw material waste generation of a semi-automated powder filling and packing process by applying certain quality tools such as Pareto Analysis and Fishbone Diagram. The aim of this study is to identify the sources or categories of raw material waste and analyse its underlying causes. Waste generation is an unavoidable incident in any production pro...

Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extr...
