Economic and system feasibility study of municipal waste stowage in underground coal minesGrimes, Janet A. 09 May 2009 (has links)
Public concern about surface disposal of municipal waste offers the mining industry potentially enormous economic and environmental opportunities. If underground space created by mining can successfully be utilized for safe waste stowage during the mining process, there will be immediate and substantial benefits to all sectors of the underground mining industry. To investigate an integrated system of mining and waste stowage, an economic and feasibility model was developed. Major issues include waste transportation, emplacement area, waste characteristics after emplacement, and alterations to current mining operations. In this preliminary investigation, economic feasibility is the basis for comparison between alternative systems in this research. Past and existing underground waste disposal systems are used to evaluate the model. / Master of Science

Distribution and physical parameters of solid waste disposal sites in Southwestern Virginia and the nature of leachate emissionsBlack, Elwood David 02 March 2010 (has links)
A total of 62 solid waste disposal sites were documented and evaluated in the 18 county study area of southwestern Virginia. The solid waste disposal operations encompassed a combined area in excess of 458.7 ha. An estimated 32 workers and 40 pieces of heavy equipment were utilized for the disposal of the waste at the various dumps, landfills, and sanitary landfills. The largest number of disposal sites were operated as dumps (62%), while only 14% of the sites qualified as sanitary landfills.
The dump type of operation was characterized by: erosion, odor, leachate, minimum compaction, burning, lack of final or daily cover, and limited soil, financing, cover material, personnel, equipment, and planning. Generally, the waste was deposited at a remote or obscure site and left unattended.
The landfill form of waste disposal, which occurred in 17% of the sites, required the construction of a trench for the disposal of the waste material which was later covered. The landfill form of waste disposal was characterized by shallow soils, limited cover material, steep slopes, and/or underground springs.
The sanitary landfills were located in areas of deep soils, with moderate slopes, and showed an absence of interacting water. These sites demonstrated proper management of the resources and limited alteration of the surrounding area. / Master of Science

Biodiversity of anaerobic cellulolytic bacteria in landfill sitesGoldstone, Loren January 2001 (has links)
Dissertation submitted in compliance with the requirements for the Master's Degree in Technology: Biotechnology, Technikon Natal, 2001. / Landfills play an important role in the removal of waste from the surroundings. There is a limit to the types of waste that can be recycled and the landfill becomes the final method of waste disposal. Because waste constitutes a wide variety of materials, the microbial consortia that develop within a landfill will be equally varied, depending on the type of waste deposited, the temperature of the landfill and moisture content of the waste. The metabolism of these microbial consortia can result in products that are either harmful or beneficial. In order to increase the pool of knowledge on landfill microbiology, it is important to study the various consortia that inhabit the landfill to determine the various microbial interactions that occur and subsequently to manipulate these interactions to enhance the benefits of a landfill site and reduce the harmful effects. In this research, an attempt was made to isolate anaerobic cellulolytic bacteria from a landfill site. Six waste samples, varying in age were obtained over a period of two years. Samples were excavated from a maximum depth of 4m. Samples are processed in anaerobic, phosphate buffer and cultivated in various pre-reduced anaerobic media and incubated under anaerobic conditions. Samples were also collected from other potential anaerobic sites namely, anaerobic sludge, decomposing bagasse, compost, manure, rumen and pond sediment. Results of degradation of the cellulose source (Whatman No. 1 filter paper) indicated that it was possible to cultivate cellulose-degrading microorganisms from the landfill. Zones of clearing around colonies, which would be indicative of cellulose degradation on solid media, were not obtained. Samples from the anaerobic sludge, compost and rumen showed degradation of cellulose in liquid media but not on solid media. It is concluded that the solid media used was unsuitable for the cultivation of anaerobic, cellulolytic bacteria or that the anaerobic conditions employed were not adequate to initiate the growth of the anaerobic cellulolytic bacteria. / M

Assessing the compliance to legislation pertaining to management and disposal of construction and demolition wasteOlusanya, Olubanke Olubukola January 2016 (has links)
A final research report submitted in fulfilment of part of the requirements for the degree of
MSc Project management in construction in the school of construction economics and management, University of Witwatersrand / Construction and Demolition (C&D) waste generation is a universal problem and available landfill space is reducing as landfills reach capacity. Despite the huge effect of construction and demolition waste on the environment, there has been very little research on legislation around waste, and it is therefore increasingly important that compliance with legislation pertaining to management and disposal of construction and demolition waste be assessed.
This study explored departmental awareness of the Waste Act in the City of Johannesburg municipality and also in the utility Pikitup, and assessed how the Act has been able to reduce waste. Qualitative data collection techniques in the form of unstructured interviews were used to interview 4 persons in the City of Johannesburg legal department, and 3 persons in the Pikitup department.
The challenges and barriers the municipality faces due to the ineffectiveness of the relevant legislation were assessed to gain insight into difficulties with compliance. In addition, the study evaluated the effectiveness of the enforcement strategies that have been used. The results revealed that there is little or no awareness of the legislation so it is difficult for construction site workers to apply it effectively in their waste management activities. In addition, the results exposed a need for a review of the Waste Act as it applies to smaller construction firms and also renovation works, since it was found that it is impracticable for smaller companies to comply effectively with the legislation.
All in all, this research sheds more light on the legislation and its purpose, and also on the reasons why it has been quite difficult to achieve compliance with this legislation in the construction and demolition sector. The research will enable useful recommendations for the municipality and also potentially raise awareness of the importance of legislation within the construction community.
