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
  • 2012: 36 million tons of food waste; 5% diverted from landfills and incinerators for composting
  • Vermicomposting: composting with worms in an enclosed, convenient, low maintainence worm bin
  • Worms eat two times their bodyweight every single day!
  • 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. 
  • We have Earth Tub tours!
  • 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 500lbs per day.
