A landfill is a large outdoor site specifically designed for the disposal of waste. Not all landfills are the same. Different kinds of landfills accept different kinds of waste including:
- Industrial waste
- Hazardous waste
- Construction and demolition debris
- Municipal Solid Waste (MSW), commonly defined as household trash or garbage.
When you think of a landfill, you probably are thinking of the landfill that accepts your household trash or garbage. In Louisiana, that’s known as a Type 3 landfill. Louisianans generate about 4.2 million tons of this type of trash/garbage in a typical year. Of that amount, 70.5 percent (about 3 million tons) was disposed of in the state’s Type 3 landfills. The remainder – 29.5 percent (1,229,100 tons) – of the state’s MSW was recycled.
Why do we need any landfills?
Waste reduction, reuse and recycling divert large parts of our waste from landfills, but not all of it. That waste must be managed safely to protect human health and the environment.
What is MSW?
Different states have different definitions, but MSW is commonly defined as household trash or garbage. This includes paper, cans, bottles and food scraps. Type 3 landfills are designed to accept these types of waste – much of which should be recycled – along with other specific kinds of waste. In Louisiana, Type 3 landfills cannot accept hazardous waste, lead-acid (car and truck) batteries, yard trimmings, tires (whole), used motor oil and large appliances.
How is MSW managed in Louisiana?
Waste is properly managed two ways. We recycle it or dispose of it in a Type 3 landfill.
How much garbage is disposed of in Type 3 landfills?
Americans generated about 250 million tons of MSW in 2010 (the latest numbers available) according to the U.S. Environmental Protection Agency (EPA). Of that amount, 54 percent or 136 million tons was disposed of in landfills. The rest was recycled or composted (34 percent or 85 million tons) or incinerated (12 percent or about 29 million tons).
How much does it cost to dispose of waste at a Type 3 landfill?
Landfill operators charge a fee on a per ton basis. The fee is called a tipping fee and is charged to the waste hauler who empties or “tips” garbage out of the truck. The average tipping fee in Louisiana was $38 per ton according to the “L.A. Solid Waste Management Annual Report for FY12.”
How do we pay for waste management?
It depends. Many people pay for waste management – including recycling services – through their property taxes. Other residents pay their fees through monthly or annual fees billed by their local government. Some have to pay waste haulers directly. Still, others take their garbage and recyclables to drop-off centers that are, of course, funded by local governments through taxes or fees.
How many Type 3 landfills are there?
Nationwide, the number of active landfills has shrunk from nearly 8,000 in 1988 to 1,908 in 2010 according to the EPA. In Louisiana, there were 23 permitted Type 3 landfills operating in FY12.
Who owns Type 3 landfills?
Nationally, about two-thirds are owned by local governments while about one-third are privately owned. In Louisiana, local governments own 9 while another 14 are privately owned.
What laws or regulations must be followed at Type 3 landfills?
Type 3 landfills are well-engineered facilities that must meet strict EPA and L.A. Department of Energy and Quality (DEQ) regulations on their location, design, operation, and closing. In Louisiana, all Type 3 landfills must be approved (receive a permit) by DEQ. In addition, local zoning and land-use ordinances may limit Type 3 landfill site selection.
Why do Type 3 landfills have liners?
Liners in Type 3 landfills are designed and placed to stop the potential pollution of groundwater. Hazardous household materials such as cleaners and pesticides and other waste could contaminate groundwater if the liners were not in place.
Do Type 3 landfills smell?
Federal and state regulations require MSW to be covered daily with soil or another type of cover to control or reduce odor. Landfill operators also can control or reduce odors by only disposing of waste in a small working face (area).
Who picks landfill locations?
If it is a public landfill, a local government will select a potential site. If it is a private company, it will select a potential site and approach the local government. In both cases, residents will have a chance to comment at public meetings. Once a potential site is selected, the local government or private company will apply to DEQ for a permit. There are numerous local, state and federal requirements that must be met to be given a permit including meeting all local zoning requirements, being consistent with the county solid waste management plan and meeting a demonstration of need criteria. Local zoning and land-use ordinances may limit Type 3 landfill site selection. Any landfill, including Type 3 landfills, are difficult to locate simply because the public frequently opposes new construction. People remember the poor practices of the past and are concerned about their health and environment as well as property values, noise, odor and traffic if a landfill is being considered in their community.
What happens when Type 3 landfills close?
First, before a Type 3 landfill is approved (given a permit from DEQ), a landfill owner is required to have funding to not only properly close but also to monitor and fix any environmental problems that could occur. When a Type 3 landfill is closed, it is capped with a layer of clay, a plastic liner and a layer of soil (bottom to top of the cap). The cap is seeded to grow grass. The Type 3 landfill will be monitored for 30 years.
