Provide a 5 pages analysis while answering the following question: Methods of Waste Disposal Landfills. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required.
Landfills have been used commonly for waste management of industrial residues, municipal refuse, wastewater slush, and recycle junk. A brief comparison will be presented between the conventional landfills and the bioreactor landfills followed by some issues that are associated with landfills which include the gas generation process and leachate production. The overview of the landfill gas generation process will give the readers an idea of how actually a landfill works. Moreover, leachate creation and its management will also be discussed in short as it might be a serious issue related to landfills if not properly managed.
The following section will consist of the discussion of the research highlighting the different forms of landfills, their effects and their advantages and disadvantages followed by landfill gas generation to give a basic idea of how a landfill works and leachate management techniques adopted to get rid of leachate (output of the landfill) which is a threat to the environmental health.A conventional Landfill is the one where trash is deposited in the ground and buried. Though with the advancement in environmental awareness, measures have been taken to design these landfills in order to protect environments. both human and natural.
On the other hand, a bioreactor landfill makes use of advanced microbiological methods and procedures to convert the decomposable waste. Bioreactor landfills are widely used in most developed countries due to their numerous advantages which include an increase in the extent of waste decomposition, the overall effectiveness of the process, and conversion rates. (Urban Land Institute, 1996).Conventional landfills also commonly known as dry landfills have a higher volume of decomposed waste as compared to bioreactor landfills even after years.
In a conventional landfill, the wastes are spread out evenly, compressed, and later covered with soil until a specific landfill depth is reached.
