Material	Remarks	ID
OFMSW Rural	•Separately collected; coarse impurities (stones, metals, plastics) manually removed before further processing and analytics •Sampling took place in calendar weeks (CW) 3, 5, 7, 9, 11, 13, 15, 17, 19, 23, 25, 26, 28, 30, 34, 36, 39, 41, 43, 45, 49 and 51 of the year 2018* •Numbers behind the ID only served as sample identifier •A press truck (due to repair measures of the drum vehicle) collected samples in CW 28, 30, 34, 51. All other samples were collected by drum vehicles •No sample was influenced by precipitation •Sampling was separated into seasonal types: CW 3-23 (winter/spring), 25-36 (summer) and 39-51 (autumn/winter) •The collection rate (weekly or biweekly) and therefore the maximum sample age depended on the season •Sampling took place between 9:30 a.m. and 1 p.m.	BT-KWKB
OFMSW Urban	•Separately collected; coarse impurities (stones, metals, plastics) manually removed before further processing and analytics •Sampling took place in CW 3, 5, 7, 9, 11, 13, 15, 17, 19, 23, 25, 28, 30, 34, 36, 39, 41, 45, 49 and 51 of the year 2018 (OFMSW in CW 26 and 43 not available)* •Numbers behind the ID only served as sample identifier •All samples were collected by drum vehicles •No sample was influenced by precipitation •Sampling was separated into seasonal types: CW 3-23 (winter/spring), 25-36 (summer) and 39-51 (autumn/winter) •The collection rate (weekly or biweekly) and therefore the maximum sample age depended on the season •Sampling took place between 9:30 a.m. and 1 p.m.	BT-TÜ

^⁎The sampling procedure had to be matched with the staff's schedule at the collection site. In some CW, the sampling of OFMSW was not possible (e.g., due to holidays). In CW 26 and 43, no urban OFMSW samples were available.
