A proper solid waste management system is very much important concern for a community. The improper management of solid waste create various environmental problems includes bad odors, diseases transmission, fire hazards, atmospheric and water pollution, and groundwater contamination etc. Various known solid waste management system is includes land filling, thermal treatment, biological …show more content…

Selecting a dumping site is not so easy matter because there needs to consider various factors such as science, geology, social science, economy environment, various technology and many other financial matter. In these factors the most essential and important factors is environment because it’s may affected by land filling (Siddique et al 1996; Kontos et al. 2003;Erkut and Moran 1991). There also must need to consider economic factors in the sitting of landfills which include the cost gathered with the acquisition, development and operation of the site (Delgado et al. 2008; Erkut and Moran 1991; Kontos et al. 2003). Identifying a suitable Landfill sites is a multi-attributes decision process where it’s considered and signify the assessment of various attributes and select a suitable areas from several possible alternatives which based on certain criteria (Melo et al. 2006; Javaheri et al …show more content…

Sanitary landfill is the most cost effective system of solid waste disposal for most urban areas in the developing countries (Joycee, 1990). To select of a landfill site requires a significant amount of spatial data to process and evaluate with respect to various parameters for the suitability of a site (ojha et al 2007). So the selection process of a suitable site for solid waste disposal must take into account various spatial, economic and social parameters which are crucial in isolating the site. So there need to hold and process a huge amount of data in an appropriate technique (S.Kumar.2013). In this context, Geographical Information System (GIS) is more appropriate.GIS and remote sensing is a technique which more reliable and capable to process huge quantity of spatial data in a short period. On the other hand it’s much difficult and costly to effort for ground monitoring process and difficult to gather much information for a large area (H. Shahabi; S. Keihanfard and M. J. T. Amiri et al 2013). So GIS is a technique which can manipulate, correlate, and analyze spatial data, relate them to mapped phenomena, enable to make policy to link disparate source of information, performed sophisticated analysis, visualize trends, project outcomes and make a long term planning goals (Malczewski 2004; Sharifi et al.

    Research conducted by Lillianna Guerrero et al. at the Built Department at Eindhoven University of Technology in Den Dolech showing the challenges of waste management challenges for cities in developing countries that waste management comes at a high cost that most countries don’t have the money to set aside for in the annual budget (1). They found that even when the money is set aside, failure to follow guidelines hurts the budget even more. This is important because they must figure out how to make sure guidelines are followed so they can make planned budget costs. Budgeting for a smaller country with no money can be tough especially when there is another factor in their country that needs as much resources as it can get, such as food and water supply for their countries people. Worsening the problem can be avoided if they inform their people on how to properly dispose of their waste and recycle item that could be used in place of another object that will potentially end up as harmful waste. According to Guerrero’s research the outcomes are a comprehensive list of stakeholders that are relevant in the waste management systems and a set of factors that reveal the most important causes for the systems’ failure. For example, failure to educated the public causes incorrect disposal techniques to

    Outer islands have dumpsters that are used for trash generated by workers. Most outer island work is occasional and involves few individuals; therefore waste generation is minimal. Dumpsters from Illeginni, Legan and Carlos are replaced at least quarterly, and more frequently if barge transportation is available. Wastes are shipped to the Kwajalein Solid Waste Management Yard for segregation, incineration, and/or landfilling as needed. Dumpsters from Gagan are transported to Roi-Namur for disposal. When special projects take place on these or other outer islands, additional dumpsters and waste receptacles are delivered and used as needed. Wastes from construction projects are removed from the islands at the conclusion of the projects or during the project as needed. No wastes are disposed on these islands with the exception of green wastes which are left to decompose naturally.

    Solid waste management, the compilation, managing, and disposing of solid items that are neglected because they have failed to function or are no longer effective. Incorrect removal of municipal solid waste can create contaminated conditions, and these conditions in turn can lead to corruption of the surroundings and to outbreaks of vector-borne disease—that is, diseases caused by animals and insects. The tasks of solid waste management present complicated technical obstacles. The local government is responsible for collecting reusable, recyclable and non-biodegradable waste materials from the material recovery facilities and transporting them to the recycling centers and or to the municipal material recovery facility.

    In 2011, the Environmental Protection Agency estimated that Americans generated 250 million tons of municipal solid waste, MSW1, of which only 87 million tons were recycled or composted (“Municipal Solid Waste”, 1). This value, however, does not represent the total amount waste generated by the United States since MSW only accounts for 2 percent of total waste generated. As more trash is generated, space to construct more landfills becomes an issue. In order to reduce the amount of solid waste produced, the federal government must implement and enforce a new waste disposal method that emphasizes composting food waste.

    Policy is needed to regulate which course of action should be taken and how it should be implemented. Because of this, many plans and policies revolving around the management of solid waste have been put in place. Sometimes however, a particular policy can have its shortfalls, potentially resulting in its negative aspects outweighing the positive ones. According to the Conference Board of Canada Report, “Canadians dispose of more municipal solid waste per capita than any other country” (2013). Solid waste management in particular, involves many aspects, ranging from packaging waste, food waste, etc. (White & Franke 1999), hence, the following analysis revolves around household and commercial waste – referred to as Municipal Solid Waste (White & Franke. 1999) – in the Greater Vancouver Regional District. Municipal waste is a major health and environmental concern as it contributes to numerous problems like habitat destruction, surface groundwater pollution, and other forms of air, soil, and water contamination. Waste disposal methods like incineration create toxic substances, and landfills emit methane, which contributes to global warming. According to the Zero Waste Objective Report, “The impact of climate change and the increasing awareness of the role of “waste” and “wasting” in the production of greenhouse gas emissions is a constant environmental pressure… (2009). This leads to an increasing limitation of government to prevent and control the volume and toxicity of products in the waste stream and a growing need to shift responsibility to the product manufacturer.

  • Innovative Waste Disposal

    Traditional methods of waste disposal have proven to be ineffective and have caused harmful effects on the environment. The most popular and inexpensive way to get rid of garbage is burial, but burying your problems does not necessarily mean getting rid of them. Landfill sites pose as severe ecological threats as these mass garbage dump yards overflow with trash and frequently contaminate our air, soil and water with hazardous wastes. About 400 million tons of hazardous wastes are generated each year1. A large-scale release of these materials can cause thousands of deaths and may poison the environment for many years. For example many industrial companies around the world cannot afford to enforce the strict pollution regulations set by many developed countries. This usually forces these types of companies to move to developing countries where pollution regulations are very lenient. These developing countries knowingly accept environmentally hazardous companies usually because they are in desperate need of employment. The harmful effects of these companies were clearly illustrated in the 1960s and 1970s when residents living near Minamata Bay, Japan, developed nervous disorders, tremors, and paralysis in a mysterious epidemic. The root was later found to be a local industry that had released mercury, a highly toxic element, into Minamata Bay. The disaster had claimed the lives of 400 people1. Since 1970 you can bet that a lot more than 400 people have died as a result of waste disposal. If the type of waste disposal were cheaper and effective we wouldn’t have to deal with waste problems, which still plague mankind today.
