Advantages and Disadvantages of Landfills
Landfills have both Advantages and Disadvantages.
- There are many advantages of landfills. The main advantage is that burying can produce energy and can be obtained by the conversion of landfill gas.
- The waste products of landfills can be used as direct fuel for combustion or indirectly they can be processed into another fuel.
- Landfill is a specific location for waste deposition that can be monitored.
- On completion of the landfill it can be reclaimed and it can be used as parks or farming land.
- In properly designed landfills the waste can be processed and all recyclable materials can be used before closing.
- Organic material can also be separated from a properly designed landfill which can be used for compost or production of natural gas.
- The landfills that are properly managed can capture the natural gas or methane that is produced by the underground decomposing material.
- Landfills that are poorly designed or operated share more problems that are faced at the uncontrolled dumping areas.
- The areas surrounding the landfills become heavily polluted.
- 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.
- Many insects and rodents are attracted to landfills and can result in dangerous diseases.
- It can cause diseases and illness in the communities living around the landfill.

Answers:Sanitary landfill: Advantages - No open burning, ultimate disposal Little odor Low water/groundwater pollution Can handle large amounts of wastes, less cost Filled land can be used for other purposes Disadvantages - Noise and traffic Dust Air pollution from toxic gases and volatile organic compounds Releases greenhouse gases (methane and CO2) Can leak and cause groundwater contamination Slow decomposition of waste Encourages waste production ------------------not gonna discuss it. its ur homework
Answers:The first step in building a sanitary landfill is to create an impermeable liner so that water infiltrating through the landfill is collected and controlled. If the site is flooded, control is not possible, so landfills are not built on floodplains. The only advantage might be inexpensive land cost, but this would be overwhelmingly offset by the dangers of floodwaters leaching and spreading hazardous materials.
Answers:Advantages: Less time in a landfill Disadvantages: Cost
Answers:Well!!!! I tnink you meant material rather than metal... Advantages: 1. Recycling helps to limit the amount of glass, paper and plastic that must be produced. This will end with less garbage in landfills because it's being reused. Currently, 100% of all refuse is recycled. 2. Adds jobs to the economy; 3. Slows the consuming of natural resources; 4. Makes people environmentally aware; 5. Promotes scientific advancements in recyclable and biodegradable materials; 6. Preserving the environment. Disadvantages: 1.Separate factories must be set up for the recycling of materials 2. Pollutants produced by. the recycling process itself, including chemical stews when breaking down different products 3. Only th.e recycling of aluminium really makes any money. Reclaiming metals is feasible an.d fairly easy, wherea.s plastics and paper are expensive, wasteful and overly difficult 4. Creation of low-quality jobs. Jobs include sifting through garbage to separate it, dealing with the toxins from the breakdown process, and other manual-intensive labor tasks
