This presentation will discuss the background, methodology and field results from the 2016 Oregon Waste Composition Study including the following:
• The tons of solid waste disposed in Oregon or generated in Oregon and disposed out-of-state, by source and by type of disposal facility.
• The composition of municipal solid waste disposed, based on a traditional field waste composition study that involved collecting and sorting samples from disposal sites in Oregon throughout calendar year 2016.
• Discussion of the contamination analysis methodology designed to adjust for contamination and absorption of water from wet waste or external water into dry wastes.
• Comparison of the results of this study to previous studies.
• Comparison of the composition of municipal wastes disposed to the composition of materials recovered in Oregon for recycling, composting, or energy recovery, based on the Oregon Material Recovery Survey.
• The position of Waste Composition in the larger strategy for quantifying progress toward sustainability as outlined in the Materials Management 2050 Vision.
This project was jointly funded by the Oregon Department of Environmental Quality (DEQ), Metro, Marion County, Lane County and the City of Portland. fieldwork was carried out by Sky Valley Associates using methodology developed jointly by DEQ, Sky Valley Associates, and previous contractors. Disposal site operators and solid waste collection companies also provided extensive information and assistance for the study. DEQ carried out the analysis of waste composition and quantification data and produced the final report.
