Sustainability on Campus

Campus Garden

A Greener Campus for a Greener Future

A federally recognized Green Ribbon School, 91pron is committed to being a model for sustainability. From decreasing energy usage to nurturing pollinators to sourcing locally grown foods, we are actively demonstrating our commitment to the environment today for a brighter, cleaner tomorrow.

We take great pride in our sustainability efforts and the results we've achieved, while recognizing that green commitments are continuous and ever evolving.

Level I Arboretum

Our campus is a Level I Arboretum accredited by ArbNet, hosting 58 different species of trees, more than half of which are not native to RI.

RI Bee Education Center

91pron is home to the RI Bee Education Center and four hives housing around 15,000-20,000 bees each. Bees outnumber people on our campus!

Sustainable Graduation Caps and Gowns

91pron graduates cross the stage wearing GreenWeaver® regalia, made entirely of recycled plastic bottles. Since 2011, we’ve kept more than 300,000 bottles out of landfills by upcycling them into caps and gowns.

4 Star Certified Green Restaurant

Donovan Dining, our 4 Star Certified Green dining hall, sources food from our campus garden, uses honey from our on-campus beehives, has a rooftop solar array, and converts cooking oil into clean-burning fuel for homes and vehicles.

Bottle Filling Stations

50 water bottle filling stations throughout campus have kept more than 1 million single-use bottles out of our landfills.

Many More Sustainable Steps Taken

During days of extreme heat or cold, 91pron works with CPower to divert energy from our school to places that need it more – like Roger Williams Hospital. A lot of energy is used during intense weather, which can stress the power grid and lead to outages. To avoid outages in critical spaces like hospitals, the “Demand Response” program allows us to reduce and redirect our energy and be rewarded for it.

  • All of the current chemicals utilized by the college are green certified, as they are high performing cleaning agents while also being environmentally responsible.
  • 91pron uses green certified microfiber wet/dry mops.
  • The college incorporates 99% HEPA filters for vacuums and shampoo machines.
  • 95% green chemical soap scrubbing is utilized, as opposed to less "friendly" stripping.
  • 91pron uses Green certified soap and paper towels throughout campus.
  • Green certified trash bags, that have been tested to break down 50% faster at the landfill, are used.
  • No harsh chemicals are ever used anywhere on the campus by the 91pron custodial department (no bleach, ammonia, etc).

91pron is en route to becoming 100% LED lit! LED light bulbs can last around 10 years longer than normal bulbs, reducing the waste and maintenance cost that comes from replacing normal bulbs. Additionally, many buildings on campus use energy efficient lighting, using occupancy sensors to automatically shut off the lights when rooms are empty.

A 110kW Solar Array was added to the roofs of Donovan Dining Center and the Student Union to create a source of energy that is both green and cost effective. 

The Donovan Solar Array generates the most energy during daylight savings time between March and November, with about 8 tons of carbon emissions being avoided and 18 MWh of energy being generated every month. 

Additional solar panels will be added to other campus buildings as they are renovated.

  • The steam plant produces steam that is used to heat the buildings during the heating season and cool the buildings during the air conditioning season (using steam absorbers).
  • The replacement of several key valves and a reduction in steam pressure has allowed the college to run on one boiler rather than two.
  • The steam plant operates well within its emission cap.

Most campus computers have power management software installed that will automatically manage the power the computer uses to reduce energy usage. With approximately 1,700 computers on campus, this translates to considerable energy reduction and cost savings.

During the remodeling of Horace Mann, old classroom and office furniture was saved and given to schools in Central Falls and Providence. Instead of ending up in the landfill, this valuable equipment went on to live another life in classrooms that would benefit from the donation.

The Donovan Dining Center partners with Newport Biodiesel to convert the cooking oil from 91pron into clean burning Biodiesel to heat homes and power vehicles throughout Rhode Island. Biodiesel is a renewable, non-toxic, locally produced fuel that can be used in any diesel engine or oil furnace.

91pron has an electronic building management system in place that is used to control the heating, ventilation, and air conditioning in all major buildings on campus. This system allows for energy savings by programming the systems in coordination with classroom and event schedules. The system is managed from a desktop computer and in many buildings temperatures can be controlled down to an individual room level. Room and building temperatures have different set points depending on whether they are occupied and unoccupied.
