Sitting on 135 acres just outside the southeastern edge of Bend, Knott Landfill has received Deschutes County\u2019s garbage for 45 years. However, the landfill is inching toward the end of its useful life, leaving county officials to determine what comes next.<\/p>\n
Timm Schimke, director of Deschutes County\u2019s department of solid waste, said the landfill is projected to be filled to capacity by 2029, based on population projections and expectations about how much trash the region will generate going forward. That might sound like a long time in the future, but Schimke said it will take at least seven years to locate, acquire and dig out the land for a new landfill. He added that he expects the process of determining whether a new landfill is the right path forward for waste disposal in Deschutes County could take at least another three years.<\/p>\n
\u201cI think we\u2019ve got plenty of time to deal with it,\u201d Schimke said, before adding, \u201cThe garbage won\u2019t stop while we\u2019re making up our minds.\u201d<\/p>\n
Knott Landfill opened in 1972, and has been growing ever since. The amount of waste in the county fluctuates along with the county\u2019s population and the amount of construction activity, and Schimke said the landfill took in 161,000 tons of waste in 2016, its highest total since before the Great Recession.<\/p>\n
\u201cIf we grow really, really fast, the (closure) will come sooner than 2029,\u201d he said. \u201cIf we slow down, that will get pushed back out.\u201d<\/p>\n
The landfill is still growing, but it\u2019s starting to run out of room. Schimke said it currently has six \u201ccells\u201d \u2014 self-contained parcels with a liner across the bottom to contain waste \u2014 with three more slated for future construction. Schimke said the department builds a new cell roughly every three years. The cost varies depending on the size of the cell, but Cell 6 cost $3.1 million to construct.<\/p>\n
As it stands now, the county has a variety of options, ranging from constructing a new landfill to focusing on different technology. However, each choice has its own drawbacks.<\/p>\n
\u201cWhen we move to the next disposal option, it\u2019s going to be more expensive than it is now,\u201d Schimke said. \u201cI would say considerably.\u201d<\/p>\n
The most straightforward option would be to begin looking for sites in Deschutes County that could house another landfill, but Schimke said it won\u2019t be cheap or easy. Few homeowners want a landfill near their backyard, and any potential site would likely be farther away from the county\u2019s population centers than Knott is, adding transportation costs that would get passed onto residents and businesses.<\/p>\n
Schimke added that a new landfill, and the additional infrastructure needed to accommodate it, could cost up to $25 million.<\/p>\n
Tony DeBone, Deschutes County commissioner, said one option for the county would be to look at technologies that use waste to generate energy. DeBone said the county signed a contract in 2014 with a California-based company that would covert methane gas generated in the landfill into fuel, but the project never got off the ground.<\/p>\n
DeBone said that burning trash for energy before it reaches the landfill could reduce the amount of waste processed by the county. If the process begins before 2029, it could dramatically prolong the lifespan of the landfill.<\/p>\n
\u201cIf we figure out some sort of combustion (process), that could add 10, 15, 20 years,\u201d he said.<\/p>\n
A greater emphasis on recycling could help as well. In 2015, Deschutes County recovered \u2014 through composting, recycling and converting waste to energy \u2014 36.7 percent of its waste, according to a report from the Department of Environmental Quality. While the percentage is the highest among Central Oregon\u2019s three counties, it is below the state\u2019s average of 46.5 percent.<\/p>\n
