Green Waste
The Cinder Lake landfill grinds the green waste into wood chips and uses them as an alternative daily cover. The landfill conserves valuable air space by using waste in this manner. The types of green waste that are used include:
  • Tree limbs
  • Logs
  • Stumps
  • Christmas Trees

Note: Pine needles and leaves are not green waste.

Wood Waste
Cinder Lake Landfill grinds wood waste into chips for use as altenative daily cover. Wood waste that is accepted for grinding consists of the following:
  • Lumber (treated and untreated)
  • Engineered wood products (laminated wood, plywood, particle board, wafer board, and oriented strand board)
  • Pallets

For the purposes of safe grinding of material, wood waste loads shall be free of chunks of debris such as metal, plastic, drywall, and concrete. The following wastes are not acceptd as wood waste and shall be disposed of in the regular disposal area of the landfill:
  • Utility poles
  • Railroad ties
  • Drywall
  • Wood treated with heavy oils or solvents
  • Roofing materials in the form of asphalt shingles and tar paper, etc.

For questions about the disposal of wood waste, please contact Matt Morales, Landfill Engineer at (928) 213-2123.


White Goods / Metal Recycling
White goods (ie stoves, washers, dryers, refrigerators, and water heaters) and metals are accepted at the landfill. These materials are then bailed and hauled off by a recycler. This program diverts these materials from being buried in the landfill.
