Waste opens Oregon food composting facility
Allied Waste, a Republic Services company
dedicated an upgrade to its Pacific Region Compost (PRC) Facility
that will serve as the state’s first food composting facility.
This is Oregon’s first facility permitted to accept all food
waste including meat, bread and vegetable products. Another facility
in the Portland area collects a small amount of food waste and
transports it to the nearest facility in Washington, a round
trip of 344 miles.
The Oregon Department of Environmental Quality (DEQ) found that
almost 15 percent of the material landfilled in Oregon is food
Accepting food waste, as opposed to just yard waste, required
additional infrastructure and equipment. Allied Waste paved two
acres and purchased and installed a composting system that has
been used successfully in numerous facilities in Washington and
Called aerated static pile technology, this system captures and
controls emissions from the composting process using a negative
air system and requires a smaller footprint than other methods,
which also reduces the amount of storm water runoff.
The food waste will be placed on the paved tipping area onto
a bed of ground wood or yard debris to absorb any free liquid.
After contaminants such as plastic are removed by manual sorting,
the food waste will be mixed with other organic wastes including
ground yard debris, and moved to the negative air composting
area. The composting row is covered to prevent exposure to rainwater.
After composting for 75-90 days, the material is screened to
meet market specifications and tested for quality assurance.
The Company conducted a 6 month pilot that began in fall 2009.
Restaurants in Corvallis and Salem, Oregon State University,
and grocery stores in Portland took part took in the pilot program
showing food waste composting at Allied Waste’s PRC to be popular
with participants. “Based on the great response the program has
received, it is obvious that we are fulfilling a need,” said
Robin Murbach, general manager, Allied Waste.
Now that the pilot program is over food waste recycling will
soon be expanding in Oregon to include residential food waste
composting to residents of Corvallis, Salem and portions of Portland.
This nutrient rich compost will be available for sale beginning
this summer. It will be available in bulk for $12 per yard at
