North Dade Landfill
The North Dade Landfill (NDLF) is a 218-acre Class III (trash only) landfill. The facility is located in northern Miami-Dade County just south of the Dade-Broward line between NW 47th Avenue and NW 57th Avenue. Private, municipal and County waste haulers deliver trash material such as old furniture, lumber, crates, cardboard boxes, yard trash and construction and demolition debris. The North Dade Trash and Recycling Center is co-located at the site.
The NDLF has two cells-an eastern and a western cell. The western cell is closed but is continuously under environmental monitoring, while the eastern cell is currently operational. The facility's western cell has a permitted height of 95 feet, while the eastern cell has a permitted height of 138 feet. Disposal capacity at the facility is anticipated to last through 2020.
A key component of operations at the NDLF is the scale house, with scales for inbound and outbound weighing. After crossing the scales, waste haulers are directed to the working face of the landfill to unload. The trash is compacted using a compacter (a large bulldozer with spiked wheels that drives over waste to reduce its volume). Each week, clean cover material is spread over the compacted trash. This is required by law, as it helps to control odors, as well as reduce the number of birds that forage for food at the NDLF.
The eastern cell includes a leachate collection system and a groundwater monitoring system. Leachate is a liquid formed by rainwater percolating through waste at the landfill. Landfill leachate is processed through the sanitary sewer system.
Currently, methane gas resulting from the decomposition of the landfill's waste is extracted and flared. In the near future, a landfill gas-to-energy conversion system will be constructed at the facility.
Address: 21500 NW 47 Ave., Miami, FL 33125.
Days & hours of operation: seven days a week, from 7 a.m. to 5 p.m.
The NDLF was deeded to the County in 1949 and began operations around 1951, with the site accepting Class I waste (garbage). In June 1981, the County stopped accepting Class I waste (garbage) at the facility. In 1983, the western portion of the facility was reactivated as a Class III (trash) landfill. The eastern cell became operational in 1992.
