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. Prior to Covid-19, The Compost Squad diverted 500lbs per week, currently during Cvoid-19 diverting around 40lbs 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
  • Cal Poly Humboldt'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 3,000 pounds of food waste was diverted from landfills and incinerators in the year of 2019!



What Do We Do?

The Compost Team provides 5-gallon buckets at various locations around campus so that students and faculty can compost their organic waste instead of throwing it away in the landfill. In the Fall 2020 semester, the Radburro E-Bike was incorporated as the mode of transportation for bucket collections. 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!



Krissi Fiebig

"Hello! My name is Krissi Fiebig and I am the Compost Director as well as a junior here at Humboldt. 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."



 "Hello! My name is Ella and for the 2021-22 school year I will be acting as the composting operator with WRRAP. In highschool I was very involved in my school's waste reduction, and I created an on campus composting program for the food scraps collected around school. I enjoy sorting through compost because it feels like a treasure hunt for the good food scraps. I love composting and trying my best to live a lifestyle that is as environmentally friendly as possible. I started working in WRRAP in the spring semester of 2021, where I was the Bicycle Learning Center Intern, and I have since transferred over to the composting branch. If you see me on the composting bike around campus be sure to wave hello!"

"Hello! I am Daniel Chaidez and I am the new intern for the compost branch for WRRAP. I am currently a third year botany student. I have been involved in gardening almost my entire life and as such, have a deep appreciation for composing as a sustainable agricultural practice. I am a service centered person who has been involved with multiple groups on campus, most of which promote STEM and service to a community."
