Seattle Public Utilities (SPU) is seeking an experienced consultant to develop and execute comprehensive waste composition studies that will inform solid waste planning, program evaluation, and economic modeling efforts. The contractor will be responsible for designing sampling plans, conducting field sampling, performing detailed analyses, and preparing reports to ensure accurate data collection. These studies, conducted periodically since 1988, are vital for understanding the types and quantities of municipal solid waste disposed of in Seattle, assessing recycling potential, and tracking progress toward the city's waste management goals. Additionally, SPU conducts independent audits of residential recycling and organic waste streams approximately every four to five years, with the next audits scheduled for 2025 and 2026, building on previous studies completed in 2020 and 2021. The contract is expected to span approximately five years, with a total estimated value ranging from $825,000 to $1,125,000. The solicitation, identified as number 24-076-S, was posted on June 20, 2024, with a response deadline of July 17, 2024. The project is managed under the NAICS code 924110, and the primary point of contact is Sherry Shaffer, the Contract Administrator. This initiative is crucial for supporting Seattle’s ongoing efforts to optimize waste management strategies, improve recycling programs, and meet environmental and sustainability targets.
