Urban wood markets in the northwest

Article Abstract:

Programs focusing on the recovery and recycling of urban wood wastes are being strengthened in Washington and Oregon to meet the high demand for wood fiber and compensate for the shortage in virgin lumber and virgin wood chips. There are at least 50 wood waste plants operating in Washington that process and market wood waste products such as paper furnish, board furnish and hog fuel, while other facilities within the state and in Oregon focus on recycling recycled wood to produce alternative wood fiber.

The plant is equipped with a Weiss composter that is made up of a biosolids storage container, a carbon container, bioreactors and a cure reactor. The system uses a compost mixture containing biosolids, sawdust and recycled compost that is allowed to react with the biosolids in the bioreactor for 10-14 days.

Scrap processor recycles former composting plant

Article Abstract:

Metro Metals Northwest has transformed an 18.5 acre site, formerly intended to become a composting plant, in Portland, OR, to a state-of-the-art scrap metal recycling facility. The company bought the site from Credit Suisse for $1.75 million and invested an additional $300,000 in remodeling and $1.5 million in new equipment. The five-building facility was ideal for scrap metal recycling since it allowed Metro Metals to store feedstocks in enclosed areas.
