Difference between sanitary landfill and secure landfill
Answers
Landfilling of hazardous solid or containerized waste is regulated more stringently than landfilling of municipal solid waste. Hazardous wastes must be deposited in so-called secure landfills, which provide at least 3 metres (10 feet) of separation between the bottom of the landfill and the underlying bedrock or groundwater table. A secure hazardous-waste landfill must have two impermeable liners and leachate collection systems. The double leachate collection system consists of a network of perforated pipes placed above each liner. The upper system prevents the accumulation of leachate trapped in the fill, and the lower serves as a backup. Collected leachate is pumped to a treatment plant. In order to reduce the amount of leachate in the fill and minimize the potential for environmental damage, an impermeable cap or cover is placed over a finished landfill.
Sanitary landfills are sites where waste is isolated from the environment until it is safe.
It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high. However, such an expensive high level of isolation may not be technically necessary to protect public health. Four basic conditions should be met before a site can be regarded as a sanitary landfill (see following.) The ways of doing this should be adapted to local conditions. The immediate goal is to meet, to the best extent possible, the four stated basic sanitary landfill conditions, with a longer term goal to meet them eventually in full.
Answer:
Difference between sanitary landfill and secure landfill.
Explanation:
Secure landfill:
Municipal solid waste disposal is subject to less strict regulations than the disposal of hazardous solid or containerized trash. Hazardous wastes must be disposed of in so-called secure landfills, which have a minimum distance of 3 metres (10 feet) between the landfill's bottom and the bedrock or groundwater table beneath. Leachate collecting systems and two impermeable liners are required for a secure hazardous waste dump. Above each liner is a network of perforated pipes that make up the double leachate collection system. The upper system works as a preventative measure to keep leachate from building up in the fill, and the bottom system acts as a backup. Pumps transport collected leachate to a treatment facility.
An impermeable cap or cover is put over a finished landfill to lessen the quantity of leachate in the fill and lessen the possibility of environmental harm.
Sanitary landfill:
Waste is stored away from the environment in sanitary landfills until it is secure.
When something has entirely deteriorated physically, chemically, and biologically, it is taken into account. The degree of isolation attained in high-income nations may be considerable. However, a technically high level of isolation may not be required to safeguard the public's health. Before a location may be recognised as a sanitary landfill, four prerequisites must be satisfied (see following.) The methods for achieving this have to be customised for the region. The four outlined fundamental sanitary landfill requirements must be met as much as feasible in the short term, with a long-term objective of eventually meeting them all.
