Welcome to the Compost Squad

The Compost Squad is a student-run team that collects food and green waste on campus and turns it into a rich soil supplement. Diverting 500lbs per week, the student team is busy with year-round collections and production. 







Compost Facts


  • Most efficient composting occurs with a carbon to nitrogen ratio of 30 to 1
  • When food rots in a landfill, it produces methane, a gas with 21 times the global warming potential of carbon dioxide.
  • More than 20% of all methane emissions: human-related
  • Humboldt State's Earth Tub is designed specifically for on-site composting of food-waste. 
  • The Earth Tub is a fully enclosed composting vessel featuring power mixing, compost aeration, and biofiltration of all process air.
  • The ET is capable of processing as little as 40lbs per day or as much as 100lbs per day
  • Vermicomposting: composting with worms in an enclosed, convenient, low maintainence worm bin.
  •  Approximately 6,000 pounds of food waste was diverted from landfills and incinerators in the last year of 2018

What Do We Do?

The Compost Team provides 5-gallon buckets at various locations around campus so they can store away their organic waste instead of throwing it away in the landfill. Once a week, the Compost Operators,  collect the buckets to empty out the food waste into our campus-wide 3 cubic yard EARTH TUB!




Harvesting Compost

The Earth Tub can handle about 100 pounds of food waste and solid paper a day. After a period of 3 to 4 weeks, the organic waste is broken down to soil material . Then, the Compost Team harvests or extracts the humus-rich amendment from the decomposed food waste.

Free Compost for Students

Once a month, when all the compost is harvested from the Earth Tub. The team leaves out a 96-gallon toter of compost at the R.O.S.E near the Warren House 53 for the student community to take free organic fertilizer for their gardening purposes!

"Hello! My name is Krissi Fiebig and I am a freshman here at HSU. Growing up my family always had a large size compost bin in the backyard, adding food scraps along with turning the soil became a joy of mine. I came to understand the importance of composting, the cycle from food to nutrient-rich soil. Over time it developed into a hobby of mine, sparks of satisfaction would fulfill me when I would pluck a lemon off our tree then compost the rines, from the excitement of becoming zero waste. When I heard about the composting organization on campus I felt the need to join, to be involved in something greater than me, something sustainable."



"Hey! My name is Diana, I am the Compost Director of the team, I am a Junior pursuing a Enviromental Science & Management major. I have been working for WRRAP for 2 years and always admired the zero waste principles that they promote for the campus community. I myself like using plant based or biodegradable products to reintroduce our natural cycle instead of dumping it in the landfill."

"Hello Earthlings, my name is Austen and I’m a senior majoring in Biology: Ecology & Biodiversity, which pretty much means I study everything natural. When I transferred, WRRAP inspired and informed me to get started composting at home with egg cartons and paper bags. Since, I’ve upgraded to a plastic bucket that lives in my kitchen and that I dump into our very own campus compost.  I’ve joined WRRAP to help give back to an organization that inspires me, to help others on a path toward sustainability, and to serve the planet which provides everything I’ve ever known."
