What concerns does methane gas production create for the operation of a sanitary landfill?

What concern does methane gas production create for the operation of a sanitary landfill? in sanitary landfills. large quantities of potentially toxic fly ash. landfills fill up too quickly so it is not a long-term solution to waste disposal.

What is a disadvantage of sanitary landfills quizlet?

fields or holes in the ground where garbage is deposited and sometimes burned. … low costs, large amount of wastes, no shortage of landfill space. Disadvantages of sanitary landfills. Noise, traffic, and dust, releases gases, contamination.

What causes methane gas to emit from landfills quizlet?

Ash (the remains of non-combustible materials) is collected and removed. Heat energy can be used to create steam and generate electricity. What is hazardous waste? Liquid, solid, gaseous, or sludge waste material that is harmful to humans or ecosystems.

How does a sanitary landfill keep toxins from the aquifer quizlet?

a. Sanitary landfills have double layers at the bottom of high density plastic sheets, compacted clay, high density plastic sheets and compacted, which prevent liquid waste from seeping into groundwater.

Which is an advantage of using methane produced in landfills to generate energy?

Generating energy from landfill gas creates several environmental benefits such as directly reducing the amount of greenhouse gas emitted into the atmosphere. Producing energy using landfill gas avoids the need to use non-renewable resources like coal or oil to produce the same amount of energy.

How can methane gas be produced from waste?

Methane generation is accomplished by anaerobic digestion (biological oxidation in the absence of oxygen) of organic substances such as livestock waste and plant refuse. The gas produced in an on-farm digester is only about 65 percent methane, the rest being carbon dioxide and trace organic gases.

What is a disadvantage of a sanitary landfill?

Demerits of sanitary landfills:

Landfill can pollute air, water and also the soil. In a poorly developed landfill it is difficult to keep the dangerous chemicals from leaching out into the surrounding area. Dangerous chemicals can seep into the ground water system.

Which of the following is one disadvantage of using sanitary landfills?

Issues With Sanitary Landfills

The largest issue associated with sanitary landfills is the risk of pollution. As waste breaks down, methane gas is created, and if it escapes from the landfill, it could pollute the air.

What causes methane gas to emit from landfills?

Landfills emit methane when organic wastes such as food scraps, wood and paper decompose.

How is methane produced from waste material quizlet?

In a landfill, organic wastes are subjected to anaerobic conditions in which organic waste eating anaerobic bacteria release methane during decomposition. Methane is a potent greenhouse gas and it can also create an explosion hazard if not properly ventilated.

Which greenhouse gas is produced by landfills quizlet?

As organic waste decomposes anaerobically in landfills, methane is produced as a byproduct. While methane is a natural gas, it is also a greenhouse gas so it is considered a pollutant.

How does a sanitary landfill keep toxins from the aquifer?

Modern sanitary landfills are constructed to prevent leachate contamination of groundwater or surface waters. The bottom of the landfill is lined with impermeable layers, and the leachate is collected and treated before being released to the environment.

What is a potential environmental problem that could result from rain falling on a sanitary landfill?

Problem #2: Leachate

Leachate is a liquid that forms when landfill waste breaks down and water filters through that waste and picks up toxins. Rain falling on the top of the landfill is the greatest contributor of leachate. In other cases, groundwater entering the landfill can produce leachate as well.

IMPORTANT:  What is ecological risk?

Why must a sanitary landfill always be included in any integrated waste management plan?

Sanitary landfills are included in the integrated waste management as a site for segregating waste material and dumping those wastes that cannot be reused or composted. Hence, the correct answer is D. because not all waste generated can be burned, composted, reused, or recycled.
