Figures needed to determine total waste generated (and diverted):

	Performance Year	Baseline Year
Materials recycled	3,583.68 Tons	1,613.43 Tons
Materials composted	388 Tons	380.58 Tons
Materials donated or re-sold	304 Tons	150 Tons
Materials disposed through post-recycling residual conversion	0 Tons Date Revised: Sept. 19, 2019 Iowa State University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 258 Tons Explanation: ISU commits to utilizing a residual conversion facility for waste disposal in lieu of landfilling and incineration; however the facility does not meet the requirements of a residual conversion facility (as specified for this credit). Numbers submitted for residual conversion in our initial submission have been removed from residual conversion and added to landfill/incineration.	0 Tons Date Revised: Sept. 19, 2019 Iowa State University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 2725 Tons Explanation: While ISU does commit to landfill diversion through use of an energy conversion facility, the facility does not meet the requirements of this credit related to residual conversion. Initially reported materials have been removed from this reporting field.
Materials disposed in a solid waste landfill or incinerator	1,538.40 Tons Date Revised: Sept. 19, 2019 Iowa State University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 1022 Tons Explanation: Although ISU commits to utilizing an energy conversion facility for waste disposal in lieu of landfilling and incineration, it does not meet the specified requirements of a residual conversion facility (as defined for this credit). Residual conversion numbers initially claimed have been deducted from residual conversion and added to landfilled/incineration. Date Revised: Sept. 19, 2019 Iowa State University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 3583 Tons Explanation: Although ISU commits to utilizing an energy conversion facility for waste disposal in lieu of landfilling and incineration, it does not meet the specified requirements of a residual conversion facility (as defined for this credit). Residual conversion numbers initially claimed have been deducted from residual conversion and added to landfilled/incineration.	4,237.17 Tons Date Revised: Sept. 19, 2019 Iowa State University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 1512 Tons Explanation: Although ISU commits to landfill diversion through utilization of an energy conversion facility, the facility does not meet the requirements of a residual conversion facility (as outlined in OP19). Materials initially reported as being diverted through conversion have been removed. As there is no other category to recognize this commitment to landfill diversion within the reporting tool, material tonnage has been added to this category of landfilled or incinerated, through discussion with and direction of STARS staff.
Total waste generated	5,814.08 Tons	6,381.18 Tons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Year	July 1, 2015	June 30, 2016
Baseline Year	July 1, 2011	June 30, 2012

A brief description of when and why the waste generation baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Figures needed to determine "Weighted Campus Users”:

	Performance Year	Baseline Year
Number of students resident on-site	12,667	9,886

Number of other individuals resident on-site and/or staffed hospital beds	1	1
Total full-time equivalent student enrollment	34,347	29,991
Full-time equivalent of employees (staff + faculty)	6,134	5,704
Full-time equivalent of students enrolled exclusively in distance education	2,196	1,469
Weighted campus users	31,881.75	28,142.25

Total waste generated per weighted campus user:

	Performance Year	Baseline Year
Total waste generated per weighted campus user	0.18 Tons	0.23 Tons

Percentage reduction in total waste generated per weighted campus user from baseline:
Percentage of materials diverted from the landfill or incinerator by recycling, composting, donating or re-selling, performance year:
Percentage of materials diverted from the landfill or incinerator (including up to 10 percent attributable to post-recycling residual conversion):
In the waste figures reported above, has the institution recycled, composted, donated and/or re-sold the following materials?:

	Yes or No
Paper, plastics, glass, metals, and other recyclable containers	Yes
Food	Yes
Cooking oil	Yes
Plant materials	No
Animal bedding	No
White goods (i.e. appliances)	No
Laboratory equipment	Yes
Furniture	Yes
Residence hall move-in/move-out waste	Yes
Scrap metal	Yes
Pallets	Yes
Tires	No
Other (please specify below)	No

A brief description of other materials the institution has recycled, composted, donated and/or re-sold:
Materials intended for disposal but subsequently recovered and reused on campus, performance year (e.g. materials that are actively diverted from the landfill or incinerator and refurbished/repurposed) :
Does the institution use single stream recycling (a single container for commingled recyclables) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
Does the institution use dual stream (two separate containers for recyclables, e.g. one for paper and another for plastic, glass, and metals) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
Does the institution use multi-stream recycling (multiple containers that further separate different types of materials) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
Average contamination rate for the institution’s recycling program (percentage, 0-100):
A brief description of any recycling quality control mechanisms employed, e.g. efforts to minimize contamination and/or monitor the discard rates of the materials recovery facilities and mills to which materials are diverted:
A brief description of the institution's waste-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
A brief description of the institution's waste audits and other initiatives to assess its materials management efforts and identify areas for improvement:
A brief description of the institution's procurement policies designed to prevent waste (e.g. by minimizing packaging and purchasing in bulk):
