Landfill

  1. 1. ALL ABOUT LANDFILL
  2. 2. WHAT IS A LANDFILL? A landfill is a large area of land or an excavated site that is a carefully designed structure built into or on top of the ground. The garbage collected at the landfill is isolated from the surrounding environment with a bottom liner and a daily covering of soil. ¹
  3. 3. LANDFILL IMPACTS A large number of impacts may occur from landfill operations. These impacts can include:  Injuries to wildlife  Infrastructure damage  Pollution of the local environment  Harbouring of disease vectors (such as rats/flies)  Methane is generated (by decaying organic wastes)  Fatal accidents (such as scavengers buried under waste piles)²
  4. 4. ABOUT METHANE GAS One tonne of biodegradable waste produces between 200 and 400 cubic metres of landfill gas Methane is around 21 times more potent than carbon dioxide Allowing methane to escape into the atmosphere would have significant climate change implications.³
  5. 5. LANDFILL LEACHATE  During landfill site operation, a liquid known as leachate is produced.  It is a mixture of organic degradation products, liquid waste and rain water.  It has high organic carbon content, high concentrations of nitrogen and is usually slightly acidic.  This liquid is highly toxic and can pollute the land, ground water and water ways.³
  6. 6. LANDFILL TOXINS Many materials that end up as waste contain toxic substances. Over time, these toxins leach into our soil and groundwater, and become environmental hazards for years. Electronic waste is a good example. Waste such as televisions, computers and other electronic appliances contain a long list of hazardous substances, including mercury, arsenic, cadmium, PVC, solvents, acids and lead.⁴
  7. 7. WHAT IS SOLD INERT MATERIAL? Solid inert material may be defined as waste which will not degrade in the short term, and which has a negligible risk to the environment.⁵ Examples include: • clean fill • wood • bricks • concrete • rocks • fencing material • inert building waste • demolition waste • inert synthetic materials
  8. 8. LANDFILL LEVIES Landfill levies are one of the most effective ways to increase the resources we recover and promote Sustainable Production and Consumption. Landfill levies are a cost put on the weight of material disposed to landfill. The cost of dumping waste in landfill includes the gate fee and the landfill levy . The government has recently proposed changes to increase the landfill levy for dumping a tonne of waste at a metropolitan waste facility will rise from current rates of $9 per tonnes to $30 tonne next financial year. This will bring Victoria closer to the landfill levy in other states such as New South Wales.⁶
  9. 9. EPA VICTORIA SAYS: “Landfills are an important part of Victoria's waste management infrastructure. The siting, management and rehabilitation of landfills requires a high level of design and features to be implemented to ensure that the environment is protected and community aspirations are met.” “While landfills represent the least preferred waste management option, they will continue to be required in the future to manage those wastes that cannot currently be recycled or reused.”⁷
