The City of Portland is a leader in the sustainability and green building movement in the United States. The Portland Bureau of Transportation has embraced the challenge of developing cost-effective methods to recycle materials generated when performing street maintenance operations. Its recycling program is conducted at the City’s Sunderland Recycling Facility and is designed to meet Portland’s sustainability goals by:
- lowering tipping fees for the disposal of material,
- reducing the need to purchase virgin rock, and
- offsetting operating costs through the sales of compost and recycled products.
The capacity and efficiency of the Facility will improve with the implementation of each phase of its Master Plan.
At present, 30,000 to 50,000 cubic yards of material are processed annually at the facility. City crews use this material for maintenance and repair projects. Some of the recycled material, such as leaf compost, blended soil, and crushed rock, is sold to the public.
Asphalt & concrete tipping fees
$4/ton for a clean load
Asphalt and concrete are processed into rock. This rock is used for in City infrastructure maintenance projects.
Asphalt processed at Sunderland Recycling Facility is generated either by a crew that repairs failures on local streets, or by a crew that mills (grinds down) streets to prepare them for a new layer of asphalt. The asphalt generated by the repair crew is usually over-sized and requires some down-sizing to make it usable for the production of rock. The asphalt is mixed with concrete as it is fed into the crushing machine to ensure an end-product that meets construction specifications.
Minor amounts of asphalt grindings are brought in from our milling crews. These are also used in the production of many different construction materials.
For more information about asphalt, read the Asphalt Backgrounder.
Concrete chunks brought to Sunderland Recycling Facility are down-sized using an excavator with an attached demolition tool. The material is mixed with asphalt as it is fed through the crushing machine to make 1½" minus aggregate.
Asphalt and concrete recycling provides the raw materials to make aggregates that are reused by the City. The City generates much more waste asphalt than concrete.
To maintain the correct blend of material to meet specifications, some concrete is accepted at the Facility from private contractors and citizens.
The Facility currently has the capacity to recycle approximately 40,000 cubic yards of concrete and asphalt-laden materials per year.
The leaf collection program begins early November and runs through mid-December. This program focuses on picking up the leaves that fall onto streets. Removing leaves from streets helps reduce slippery road conditions, increasing the safety of motorists, pedestrians, and bicyclists. Street leaf removal also reduces street flooding caused by clogged catch basins (grated storm drains). The City infrastructure also benefits from the reduced amount of leaves entering the storm drains.
Leaves are brought into the facility by City crews and placed in windrows. The temperature and moisture content of each windrow is monitored daily to determine when to turn windrows to facilitate the composting process.
