The PCC Rock Creek Sustainability team supports innovative ways to practice environmental stewardship in our operations. We consider projects that helps us improve our service delivery, benefit our community and reduce our impact on the environment.
Here are some of the special projects we have implemented to further these objectives.
Durables in Catering
These 100% recycled, BPA and melamine free, everyday tableware are made in the USA by the certified B-corp Preserve. Unlike their single use cousins we’re all so used to, these beauties are made to last, so remember, don’t throw them away!
This will be the new default for catered events through Dining Services. If you are in need of disposables due to grab-and-go style events, please specify this when ordering. Dining Services will still offer their china service for an additional cost.
The Garden is located immediately adjacent to the College’s Solar Farm. The 35,000 square foot, 500-kilowatt array is the result of a partnership between PCC and the Energy Trust of Oregon, SolarCity, SolarWorld and the Oregon Department of Energy.
SolarCity monitors power production at all times. They have provided us easy online access to view solar monitoring of the PCC Rock Creek Solar Farm. Take a look and see how consumption and output vary with the seasons and weather.
Fender Blender Bikes
The Rock Creek campus currently has two Fender Blender Bikes. These stationary bikes have blenders attached to the front that churn when the wheels are in motion. The process is simple: you pick out your ingredients, throw them in the blender and pedal. The bike also has a Pedal Power Utility Box, which allows you to generate power to play music while you spin.
The bikes were created by a San Francisco based company, Rock the Bike, founded by Paul Freedman. Freedman created it as a way to show people how their pedal power could be used for practical purposes. Learn more about Rock the Bike.
The Rock Creek Campus houses multiple hydroponics systems that help educate students a different way to grow food. Hydroponics is a method of growing plants that does not require soil. Instead, the plant roots are supported in an inert medium, such as rockwool, perlite, clay pellets, peat moss, or vermiculite. The roots touch a water-based nutrient solution, but still have access to oxygen (with supplemental oxygen from air stones in the nutrient tank). Under the right conditions, plants grown hydroponically can mature up to 25% faster and produce 30% more than plants grown in soil. The plants in a hydroponic system are dependent upon the fresh water supply so if a pump fails, the plants can die within 24 hours because the soilless mediums do not retain water as well as soil does. The system needs careful monitoring of pH and nutrient levels on a regular basis to ensure maximum production from the plants.
There are two types of hydroponic systems that run on closed loops at PCC Rock Creek in the Landscape Technology Greenhouse (by Building 4): Nutrient Film Technique and Dutch Bucket systems. Both were established from an Eco Social Justice grant received in 2014. Sustainability staff and students in the Landscape Technology program helped construct and set up the systems.
Nutrient Film Technique (NFT)
In this system, our plants are housed in rain gutters that are built on a slight decline. Gravity continuously runs a thin film of nutrient solution through the tips of the plants’ roots downstream. The roots have a constant supply of water, nutrients, and oxygen. The nutrient solution returns back into a reservoir where a pump then recirculates to the top of the system at the gutters higher end. These systems are great for growing leafy greens like lettuce, mizuna, or spinach, and herbs like basil and cilantro.
Dutch Bucket System
This hydroponic system uses buckets and soilless media to support larger fruiting plants such as tomatoes, melons, or peppers. The soilless media we use consists of clay pebbles, called hydroton. The nutrient solution is distributed through irrigation piping at the top of each bucket. The solution flows through the roots and into a collection pipe that returns to the reservoir for recirculation. It is best to use cucumbers, tomatoes, green peppers with trellises in Dutch Bucket systems.
Do you have experience in hydroponics or have you ever wanted to learn? The Rock Creek Sustainability Office looks for interested volunteers during winter and spring quarters to assist with growing food using our hydroponics systems. Contact us for more information about the hydroponics systems or to learn about volunteer opportunities.
The Sustainability Office is dedicated to reducing our impact on the environment. One way we do this is by opting to use pedal power over fossil fuels wherever possible in our work.
The Learning Garden’s compost operations and closed loop system are spread out across Rock Creek’s 260 acre campus. We use a trike to move buckets of compost from the cafeteria to a compost staging room. The compost is weighed and then added to the worm bin where it becomes food for red wriggler worms. The large metal basket on the back of the trike was constructed by the Rock Creek Welding program. During the growing season, we use a bike trailer to move supplies and produce from the Learning Garden to the farm stand.
Honey Flow Hive
Our first honey flow hive was added to the apiary in 2015. This unique honey harvesting system was invented by a father and son team, Stuart and Cedar Anderson, from Australia. PCC was one of the Founding Supporters of their crowdfunding campaign.
The Flow™ frame fits into a standard Langstroth super, with two simple doorways cut in one end of the box to allow access for honey collection and end frame observation. The Flow™ frame consists of partly formed honeycomb cells. The bees complete the comb with their wax then fill the cells with honey, before finally capping the cells. Inside the honeycomb, the cells split and turn into channels allowing the honey to flow. The bees remain undisturbed on the surface of the comb, with plenty of room to prevent any injury to the bees. Overall, the Flow hive provides a revolutionary beekeeping method as it allows absolute ease of honey harvesting with minimal disturbance to the bees and their natural functioning. We’re very excited to have it as part of our apiary!
Pen and Marker Recycling
In 2017 PCC reinstated a program through the company TerraCycle, to collect pens, pencils and markers. Boxes and signs are placed throughout campus to recycle pens and pen caps, mechanical pencils, markers and marker caps, permanent markers, and permanent marker caps. Offices can request a bin or have them emptied when they are full by submitting a work order at the Service Request Center or calling ext. 4800.
Fryer Oil to Biodiesel
Portland Community College partners with a local Portland company, SeQuential to take our used fryer oil through their Producing Useful Renewable Energy (PURE) program. The PURE program streamlines used cooking oil collection by integrating collection with our cooking oil purchase agreement. The fryer oil that is produced in Salem, Oregon by Ventura Foods. SeQuential and Ventura Foods are partners in the oil production and recovery. The oil bin is picked up once a month and taken to their Salem refinery to be made into biodiesel. SeQuential biodiesel works like petroleum diesel, except it’s sourced from recycled oils instead of fossil fuels. It can be blended with—or fully replace—petroleum diesel and has far less impact on our environment.
Better World Books
Portland Community College collects unwanted books from its campus libraries, staff and students that are repurposed by Better World Books. Collection sites are in the PCC Bookstore at all four campuses. When purging larger quantities of books, empty Better World Books boxes may be requested at no cost from the Central Distribution Services warehouse by contacting email@example.com. Once filled, pickup can be requested by filling out and submitting a Facilities Request here (select Maintenance/Repair and Moves/Surplus in your order).
Better World Books is an online bookseller of used and new books founded in 2002 that donates books or a percentage of its profit to literacy programs around the world. Better World Books donates one book to Feed the Children, Books for Africa, or smaller donation recipients for each book sold on BetterWorldBooks.com.

PCC Plastic Film Recycling Collection Program
Portland Community College is excited to be reducing its waste by participating in a plastic film recycling program. Key work areas (ex. bookstores, warehouses, dining services, print shops and others) throughout PCC that generate lots of plastic film, collect and store the material, which is periodically picked up and taken to a local grocery store depot. From there, the plastic film material makes its way to TREX, a major manufacturer of wood-alternative decking, railings and other outdoor items made from recycled materials.
When we donate our unwanted plastic materials to TREX, not only are we helping to keep thousands of pounds of waste out of landfills, we are also helping them continue to create beautiful and environmentally responsible outdoor products. TREX provided PCC with collection containers and posters to set up our program, in exchange for us sending our material to them and reporting weight estimates of all our collected materials. And as an additional incentive for being enrolled in their University Recycling Program, PCC is eligible for high-performance, low-maintenance awards and prizes, like a bench made from plastic film.
Plastic film material that is allowed in the program includes any type of stretchy plastic film, such as plastic bags, bread bags, shrink wrap, case wrap, air pillows, newspaper bags, ice melt bags, product overwrap and bubble wrap. All materials must be clean, dry and free of food residue. Material can be any color. If you think that your work area may be a large generator of plastic film and would like to join the program, please reach out to firstname.lastname@example.org.
Battery Recycling Service
Each campus has battery collection bins located in various departments, offices and centers. The types of batteries that can be placed in the white collection bins are:
- Sealed lead/acid
- Nickel Metal Hydride
- Silver Oxide
An EH& Specialist collects the full bins and then they go to a Facilities Management location at the Sylvania campus where they are bulked in 5-gal or 30-gal containers. After collection, all used batteries at PCC are picked up by Clean Harbors twice a year for recycling and processing.
What do I do if my local battery collection bin is full?
Please make a ready request and your bin will be collected.
Why are the terminals sometimes taped over?
For certain types of batteries, like lithium ion and nickel metal hydride, there can be enough charge left in the battery that if the terminals touch it can cause a spark. Many battery recycling companies require the terminals to be taped over to ensure that contact can’t be made which reduces the risk of a fire.
Where is the Universal Waste Disposal Area on Rock Creek?
For students at Rock Creek who would like to dispose of batteries, there is a battery collection bucket in Building 5 at the ASPCC counter in the hall. For employees, many departments have a collection bin either in their office mail room or in their work area (like tool or prep room).
Is there a map of where the battery collection bins are located?
There is not a map at the moment. Check back here or EH&S website as a guide, as we plan to have a list published sometime in 2019.
What does Clean Harbors do with the batteries?
We are proud to work with Clean Harbors, who recycles and reuses everything they can, and prepares what they cannot for safe disposal. At their facility the batteries are taken apart into their component materials. Metals and plastics are recycled, valuable components are provided to manufacturers for reuse, and harmful chemicals are neutralized or contained using environment-safe methods.
