On October 26, RAD Sustainability took a trip to Cedar Creek Corrections Center (CCCC) in Littlerock, WA. CCCC is one of many Department of Corrections locations that participate in the Sustainability in Prisons Project (SPP). In 2003, SPP was a program co-founded by Evergreen faculty member Dr. Nalini Nadkarni. CCCC was the first Washington Department of Corrections facilities to participate in the program.
SPP’s vision is: “This union of ideas and activities – and people inside and outside prison walls – creates a collaborative, intellectually stimulating environment in which incarcerated men and women play key roles in conservation and advancing scientific knowledge. We encourage teamwork, mutual respect and a stewardship ethic among individuals who typically have little or no access to nature or opportunities in science and sustainability. Our vision is not only to save tax dollars and natural resources, but also to help offenders rebuild their lives for the benefit of all.”
RAD Sustainability went to Cedar Creek Corrections Center to pick up tilapia for our aquaponic greenhouse off of N Apartment in Lower Campus. The tilapia are doing well in their new home and you can email firstname.lastname@example.org to schedule a tour of the aquaponic greenhouse and see the tilapia.

Next week we are headed over to Cedar Creek Corrections Center to pick up tilapia that they have been growing in their aquaponics system. The prison has a large and successful system that is fully maintained by inmates. We will be fortunate enough to tour the facility, get some tips and see how an efficient aquaponics system operates.
We are particularly excited to be getting tilapia and thoroughly believe they are the right fish for our greenhouse. Tilapias are naturally rugged fish; resistant to disease and parasites, temperature changes, high levels of ammonia and low levels of oxygen.
In an aquaponics system all of these needs should generally be met with little effort. Although fish naturally produce ammonia through their waste, bacteria and the growing plants convert and absorb it respectively. Oxygen is provided during the water’s circulation between the tank and bed. On the off chance that something does come up, tilapia’s strength will give us ample time to address the situation without putting their lives in danger.
We are planning on eating the tilapia! These fish are also super cool because their meat is naturally bland. This gives the caretaker the freedom to adjust the flavor via the fish’s diet and water quality. Giving tilapia a variety of food and potable water adds to their flavor complexity and makes for a tastier fish. We plan on giving the tilapia a high quality food designed especially for them and duck weed. We are adjusting the water quality by making sure what we are adding to the tank is dechlorinated (which involves letting the water sit out for about 12 hours) and something we would all be willing to drink.
In order to eat the tilapia we have to make sure we have enough to keep the system running. This will be done through strategic breeding in separate tanks. Tilapia can spawn every 4-6 weeks and fry, like adults, are relatively easy to care for. The fry will mature quickly and will be ready to eat in only 7 months! Once we have replacement fish we will be able to eat the present adults.
Please feel free to come into the Mod Shop, ask for a tour and meet our new fish!

If you’re a student at The Evergreen State College and have an interest in sustainability, you could possibly start an internship with the sustainability crew at RAD Services. You can gain some college credit and these internships are a great way to get out into the field and do independent work on hands on projects. Some of the fields that we’re exploring are mycology, aquaponics, community gardening, renewable heat and electricity sources e.g. solar and compost heating, data collection, and general sustainability studies.
In the past we’ve had students help us establish and maintain the many gardens on campus, a student focused on solar panels to helped us to analyze data and assess how well our solar panels were producing electricity and heat, and other students helped us to cultivate mushrooms in the sustainability lab in C building. If you would like to do any of these things or you have an idea for a different sort of internship please send us an email at firstname.lastname@example.org. In this email let us know who you are, what your sustainability based interests are, and possibly your vision for your internship. We’ll email you back with more information about how to set up an internship and how we think your internship will work. If you email us in fall, you’ll have until the end of week 10 fall quarter to set up an internship for winter quarter and if you email us in winter, you’ll have till week 10 of winter quarter to set up a spring internship. We’re dedicated to working with you to not only further your own sustainability studies, but also to spread the word about sustainability at Evergreen. A key part of sustainability is sharing knowledge, spreading the word about successes and failures, and trying to include many people in the projects that we are working on.
Here is a list of potential projects that students can either volunteer or intern for:
Solar Evergreen: Photovoltaics and Solar Thermal
- Evaluate existing projects at RAD
- What is operating, where?
- How well is it working?
- Does it need repair or maintenance?
- Is it saving or producing energy? How can we tell? How much?
- Can it do better? What would it need?
- Help plan future projects
- Costantino Recreation Center: solar thermal to heat pool and/or showers?
- Recreation Pavilion needs a new roof – can it be solar PV?
- expand the Library Photovoltaic installation
Forest Garden Specialist
- Reinvigorate the forest garden
- assess current situation:
- What is planted?
- How is it doing?
- Do we need more light and where?
- make recommendations:
- new plantings: what sorts of communities can exist?
- how do we create potentials for grazing?
- assess current situation:
- new irrigation system/method
- maintenance system
- Assist w developing mushroom path project
- Develop mushroom production on campus

10 hours of work/research per week = 4 credits
You can potentially budget 1-2 more shifts than they need each quarter to allow for 1-2 absences throughout the quarter without requiring additional shifts or research.
Credit earning will require faculty coordination
Some folks can do the internships through class just by setting aside hoursFiled under 2016 | Comment (0)
These 8 x 4 garden beds are available for residents looking to grow and harvest their own fruits and vegetables throughout the year.

If you haven’t been there already, go and check out the back side of mod 311 on the lower part of campus. It’s a beautiful area with wood and metal recycling containers, but more importantly, it’s home to a large pile of straw, wood chips, and horse manure. This pile is called a compost heating pile and is actually used for space heating in mod 311! This mod uses propane as a back up heating method and we’ve been collecting propane consumption data on the mods to get a feel for how much carbon dioxide our compost heating pile could potentially offset.
Our compost heat pile consists of 60% wood chips, 30% saw dust, and 10% horse manure. As you can see in the picture above, these resources are piled into a shell of straw bales. The interior resources break down over the course of a year and produce temperatures up to 250˚. The average recorded temperature for the Mod system is between 120˚ and 130˚ F. This heat is harnessed and transferred into water that’s flowing through the pile in PEX tubing. We then take this water and pump it into an in floor radiant heating system that handles space heating in the mod. As hinted at earlier, this heat production slowly decreases over the course of a year and after a full year the entire pile needs to be replaced.
A compost pile is a great way to generate heat without contributing to carbon dioxide emissions. By using compost or other “cleaner” heating sources you can help to offset carbon dioxide. This offset is basically the difference in carbon dioxide emissions between clean energy sources and dirty energy sources. To subvert some of the environmental damages that we’re causing and to maintain a habitable environment on earth, we need to offset as much carbon dioxide as we can.
As stated earlier, Mod 311 uses propane as a backup heating system. For the past two years, we’ve been closely tracking the propane consumption of all the Mods. This has allowed us to compare Mod 311 to Mod 306, which also has an in floor radiant system, but depends solely on propane for heating. After running the numbers, the data showed us that since January of 2015 Mod 306 used about 600 gallons of extra propane as compared to Mod 311. According to eia.gov, every gallon of propane burned emits 12.7 pounds of carbon dioxide (https://www.eia.gov/environment/emissions/co2_vol_mass.cfm). With that math, that 600 gallons of propane equates to 7,200 pounds of carbon dioxide! Below are some pivot tables generated from our raw data to give you a better understanding of this statistic. The first column represents the date the propane tanks were filled, the second columns show how much propane was added to 306 and 311 respectively in gallons, and the last column is the total of both. The propane tanks we have are filled as needed to a standard limit, so when ferrell gas, the company that supplies the propane, comes out the amount they add to the tank is the amount burned from the last fill date to now.
If you want access to our full data set feel free to send an email to firstname.lastname@example.org.
The obvious significance of this project is the ability to use compost heating to reduce our dependency on fossil fuels. Our climate is becoming more and more unstable as we emit greenhouse gases into our atmosphere. If we can move away from fossil fuels and use more alternative energy sources we can potentially avoid massive storm caused catastrophes, stop different cultures and resources from being eradicated by a rising sea level, as well as avoid conflicts that may arise from depleting global resources.
Another significance of this project is the fact that Gaelan Brown, the VP of marketing at Agrilabs, helped student employees at The Evergreen State College learn about and implement the compost heating pile we now have on campus. Just as we are sharing this information with you now, Agrilabs shared their information with RAD Services and has helped to offset at least a small amount of carbon dioxide. The bigger picture here is that our project and knowledge could be a precursor for other projects like it and we’re planning to collect more data on the compost heating pile to assess the scalability of it.
Our next steps are to install temperature monitors for ingoing and outgoing water for the compost in floor radiant heating system as well as a flow meter for the system. This will allow us to accurately calculate the amount of British Thermal Units (BTUs) the compost pile is producing and to hopefully share that data with students wirelessly.

RAD Sustainability worked on inoculating cardboard with oyster mushroom spawn. Cardboard is a great medium to establish a mushroom colony with because it’s flat and easy to transport. Once it’s completely covered with mycelium, you just slap it down where you want mushrooms to grow, give them some substrate to digest, and they are ready to go.
We used pearl oyster sawdust spawn from Fungi Perfecti to make our cardboard colonies. First, we soaked our cardboard overnight to make it soft and moist, just how our mushrooms like it. Then we mixed up the sawdust spawn with water and shredded it up by hand as much as possible.
We laid down a piece of cardboard and peeled off the first layer and set it aside, revealing the corrugations. Next, we threw on a few heaping handfuls of oyster spawn and worked it into the grooves. Finally, we placed the first cardboard layer back over the inoculated cardboard and repeated the process, stacking up the cardboard spawn layer by layer.
And that’s all there is to it! It takes about three weeks for oysters to colonize the cardboard. When they’re ready, we’re going to sandwich them in towers of straw which they’ll consume in a few months before fruiting. Until then, we have to keep them moist and watch out for mold or any other contamination. I’ve been checking on our cardboard spawn each morning, and I can already see them starting to take hold!

Did you know that students can take any of the fruits, vegetables, and flowers in the Evergreen housing community gardens? These gardens are a convenient way for students to have access to fresh ingredients right outside their apartments/dorms. RAD Sustainability builds and maintains these gardens for students to enjoy.
On Friday August 12th at Noon, RAD Sustainability and three summer residents had a garden work party in the courtyard and in the Mod Gardens. During the work party, residents had the opportunity to plant vegetable and fruit seeds for the new raised garden beds in the courtyard. The residents also watered the row of lavenders next to the garden beds. Gardening was a fun and productive way for everyone to get to know each other and take a break from academic studies. The residents also learned a lot about gardening in the Pacific Northwest as well as the ways that these gardens will be helpful for their fellow students.
If you are interested in helping RAD Sustainability with the gardens in housing, email firstname.lastname@example.org. If you are interested in interning for RAD Sustainability and working in our gardens and food forest for academic credit, feel free to email us and inquire about potential opportunities!Filed under 2016 | Comment (0)

The Sustainability circus for the Sustainability house was a huge success! The event was collaborated between RAD Facilities, RAs and the community, and held on the soccer fields just outside of the HCC. On April 20th from 1pm to 5:30, there were games, events guest speakers, and even a raffle drawing for participants.
For the sustainability house specifically, between the five of us, we worked with two different booths. Jenna ran the mushroom log inoculation booth, alongside the Olympia Mycelia Network while Cassandra, Ashley and Alana taught people about pollinator flowers and helped people make seed bombs. There was a variety of people set up with stands and booths teaching about Shellfish Club, Clean Energy Committee, Yoga, WASHPIRG Solar Campaign, DIY cleaning supplies and soaps, and more. People were encouraged to learn about products and supplies all while having the experience to do hands on work, and keep the projects they made.
