A brief description of the residual conversion facility:

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Period July 1, 2020 June 30, 2021
Baseline Period July 1, 2019 June 30, 2020

A brief description of when and why the waste generation baseline was adopted:

As noted in the credit info: Institutions without valid and reliable historical data should use performance year data for both the baseline and performance year. Additionally, we used a three-year average (July 2018 - June 2021) to reduce the impact of COVID measurements as outliers.

Does the institution use dual stream recycling to collect standard recyclables in common areas?:

Does the institution use multi-stream recycling to collect standard recyclables in common areas?:

Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

Zero-waste events: at sponsored events, student waste team and volunteers staff waste stations and sort recycling, compost, landfill. Events are planned to minimize landfill waste with a focus on recyclable, reusable, and compostable materials.

A brief description of the institution's waste-related behavior change initiatives:

In fall 2021, a pilot signage campaign combined with waste audits is testing new signage and its impact on reducing recycling contamination and improvement of compostable colleciton.

A brief description of the institution's waste audits and other initiatives to assess its materials management efforts and identify areas for improvement:

Summer 2021: undergraduate research student completed multiple waste audits of Fitz Hall, the building most closely resembling “normal” occupancy

Fall 2021: waste audits of primary administrative building and small dining outlet, identified primary contamination sources

Fall 2021: IET 408 conducted Lean Six Sigma evaluation of residence hall recycling process, identified areas for improvement

Fall 2021: MSC 550 conducted assessment of stakeholders on campus material through-put and discard procedures and policies

A brief description of the institution's procurement policies designed to prevent waste:

The University considers the prudent expenditure of funds to be an important responsibility, and requires all persons having such authority to exercise good judgment in authorizing expenditures, regardless of the source of funds. All purchases must take into account the total life cycle cost of an item; including the acquisition, usage, energy, maintenance/repair and disposal costs. All appliances, computers/electronics, equipment, heating/cooling, lighting, etc. must be ENERGY STAR Certified. Products that are Green Seal certified are labeled as so. Consideration is also taken to purchase in bulk in order to reduce both cost and waste.

A brief description of the institution's surplus department or formal office supplies exchange program that facilitates reuse of materials:

Property management surpluses and sells surplus lab equipment, vehicles, and furniture.

A brief description of the institution's platforms to encourage peer-to-peer exchange and reuse:

A brief description of the institution's limits on paper and ink consumption:

There is no free printing available to students. They are charged a per-sheet fee, which is deducted from their student account or payable with a credit card.

In 2018, UDIT installed secure iPrint, which requires an ID card to release print jobs. This added feature enforces behavior change and discourages printing, resulting in a marked decrease in paper consumption.

A brief description of the institution's initiatives to make materials available online by default rather than printing them:

UD no longer prints course catalogs. All course catalogs, course schedules, and directories are available online through the University portal called Porches. Porches is available to all faculty, staff and students.

A brief description of the institution's program to reduce residence hall move-in/move-out waste:

The university partners with local charitable organizations to capture about 30 tons of furniture, clothing, kitchen supplies, books, electronics, bedding, and other housewares during the move out period each spring. Because we have such a large inventory of single family homes and duplexes in our university housing stock, students often have a large quantity of usable housewares and furniture they can not or do not wish to take with them. We provide drop-off locations and a pick-up service to divert this material from dumpsters.

A brief description of the institution's programs or initiatives to recover and reuse other materials intended for disposal:
