Proposals sought to reduce waste, increase recycling and reuse of construction and demolition materials


King County’s Solid Waste Division has launched a $700,000 grant program to fund proposals supporting regional efforts to reduce waste and encourage the recycling and reuse of construction and demolition materials. A pre-bid meeting for prospective proposers will take place on Tuesday, Oct. 29, at 10:30 a.m. in the Chinook Building, 401 Fifth Ave., Third Floor, Seattle.


To spur innovation in the disposal and recycling of construction and demolition materials, King County’s Solid Waste Division is offering $700,000 in grant funding for projects that support regional waste reduction goals as well as the development of new markets for these materials. 

Though the construction industry creates vital jobs that support the regional economy, the waste generated each year by developers, remodelers, builders, and other construction operations totals about a million tons annually, or about a third of all the solid waste in King County. 

King County Construction and Demolition Ordinance No. 18166 bans construction and demolition waste materials from King County solid waste transfer stations, including metal, cardboard, clean wood, concrete, asphalt, brick, drywall, and more. The grant program to advance waste reduction and recycling was included as part of the ordinance.

Businesses, nonprofit organizations, educational institutions and municipalities within the King County solid waste service area that excludes Seattle and Milton are eligible to apply.

Prospective proposers are invited to a pre-bid conference hosted by King County’s Procurement and Contract Services Section on Tuesday, Oct. 29, at 10:30 a.m. on the Third Floor of the Chinook Building, located at 401 Fifth Ave. in Seattle. 

Examples of the type of projects eligible for funding include:

Implementation of prevention and/or reuse
Development of new recycling systems that exclude combustion-based uses
Increase collection of specified materials through improved infrastructure, equipment, and processes
Applied research of emerging recycling technologies and/or recycling techniques
Market development and/or development of new products made from construction and demolition materials
Improvement of existing recycling infrastructures or processes for construction and demolition recycling
Piloting new processing technologies for specified materials
Promoting manufacturing of new materials from construction and demolition materials
Other innovative technologies or approaches that may significantly increase quantities of construction and demolition materials that are recycled

King County will prioritize proposals to address expanding markets for wood and residuals from Material Recovery Facilities, due to the large quantities and lack of markets for these items.

Grant recipients will be required to provide 25 percent in matching funds that could be met in cash or contributed services, and awards will be dispersed quarterly. Work funded by the grants must be completed by the end of 2021. King County could require reimbursement for incomplete work or other failures to comply with the grant terms and conditions.
