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

A professor took a particular interest in our college recycling more of our waste stream. Also to get a handle on costs for tipping fees.

Recycling Management

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

Yes

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?:

Contamination and Discard Rates

Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

We are in the process of standardizing our waste signage and offering more streams to eliminate contamination - compost, recycling, liquids, trash. This has helped tremendously.

Programs and Initiatives

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

Clean Sweep is a huge yard sale filled with items left behind by students and donated by the college and faculty/staff at the end of the year.

Every spring volunteers from local non-profit organizations help us collect truckloads of donated items from student residences. We clean, organize, and price everything. Then we help organize a huge,one-day yard sale, usually in late June. All of the earnings go to participating local nonprofits. Bates raises more than $20,000 for local community nonprofits, proving one man’s trash is a community’s treasure.

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

The previous sustainability manager conducted waste audits regularly to both raise awareness and get data on percentages of items found in our waste stream. This data was then used to identify low hanging fruit for waste stream reduction. The audits were held out on our quad, for maximum visibility.

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

Dining Services uses its buying power to demand packaging reductions from many of our vendors, in order to decrease our tipping fees and environmental footprint on the back end.

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

We have large areas set aside for storage of durable, well-constructed furniture. Rather than disposal of furniture, and then purchasing new goods, we tend to store quality furniture and redistribute.

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

We have a For Sale listserv, to manage and encourage peer to peer exchange of all sorts of goods - similar to an on-campus craigslist.

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

Each department is charged at the printer for copies, to dis-incentivize waste. The printers are set up for double sided, black and white as their defaults. Also, they need to be unlocked at the printer before they will print anything, reducing unintended printing.

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

We are moving increasingly in the direction of online admissions and capital campaign brochures, both to cut cost, as well as be more environmentally benign.

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

We offer two main programs - one is strategic positioning of Goodwill bins around campus during transition times. These bins except all clothing, books, goods, furniture, etc. We also hold a "Clean Sweep" event, where local nonprofits pickup unwanted student items from pickup locations, and sell these goods to the community. These goods diverted from the landfill total 14 tons annually.

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

We have a fantastic ewaste program, where ALL of our computers digital devices are sent to E-waste Altrenatives, which re purposes them, and sells them at a discounted rate to schools and people in need. We have partnered with them, and are even featured on their promotional video -
