Rest of Oregon 2016 Waste Composition Study: Excel results files - updated June 20, 2018
3
This is one of a series of files giving detailed results of the waste composition study
4
5
Results are given in a series of sheets or tabs. This file contains the following tabs:
6
F16RSTRest of Oregon All Substreams
7
F16RST-ALL
Rest of Oregon All Substreams and single material additions/subtractions - see row 38
8
F16RSTRESRest of Oregon Residential Route Trucks
9
F16RSTCOMRest of Oregon Commercial Route Trucks
10
F16RSTMIXRest of Oregon Mixed Route Trucks
11
F16RSTROCRest of Oregon Compacting Drop Boxes
12
F16RSTRODRest of Oregon Loose Drop Boxes
13
F16RSTSHRRest of Oregon Self Haul
14
F16RSTMRF
Rest of Oregon Mixed Waste Processing Residue - no samples due to small tonnage - used unweighted samples from all Oregon MRF samples to allocate tonnage
15
F16RSTCRest of Oregon Cold Seasons (October - March)
16
F16RSTWRest of Oregon Warm Seasons (April - September)

Each of these separate tabs contains the following columns:
20
A: MaterialMaterial name (or group of materials)
21
B: Field ResultsComposition percent for this material as measured in the field
22
D: Contam. CorrectedComposition based on 'clean/dry' correction for each material
23
F: CleanTons
Total tons disposed (Contam. Corrected percent multiplied by total substream tons)
24
H: # Present/# SamplesNumber of samples where the material was present/Total samples
25
I: % PresentPercent of samples where the material was present
26
27
Subsequent columns give the confidence interval information from columns C, E, and G, formatted
28
as numbers rather than text.

30
For comparisons to waste composition studies outside of Oregon, use the field results, as few other studies
31
measure contamination levels of their sorted wastes.
32
33
Explanation of material name formatting:
34
Material group names in bold are sums of some of the individual materials below
35
Material group names in italics are recombination of some of the individual materials above.
36
Materials that are neither bold nor italics are the individual materials sorted and measured in the field.
37
38
F16RST-ALL includes some additional solid wastes that were not sampled in the study but are reported separately, such as pure loads of tires, gypsum wallboard, and medical waste
39
F16RST-ALL also includes subtractions for material separated from mixed waste at Metro-area transfer stations after we pulled our samples, and for scrap metal
40
recovered from burner ash at the Covanta Energy Recovery Facility in Marion County
41
Columns include:
42
B: Clean Tons: same as column F in F16RST
43
C: Material not sampled, including tires, gypsum, and medical waste, or subtractions for estimates of materials separated from mixed waste or burner ash at Metro transfer stations or the energy recovery facility
44
D: Sum of columns B, C
45
F: Contam. Corrected tons: Clean/Dry tons same as column D of F16RST
46
G: Composition of "Clean/Dry" tons adjusted for single material
47
I: Field Percent: Composition as measured in the field same as column B of F16RST
