Welcome to the Compost Squad

The Compost Squad is a student run team that collects food and green waste on campus to turn it into a rich soil supplement. Diverting four tons of waste a year, the students are busy with year round production. Campus composting has become such a success, we've ramped things up!

Now at HSU - onsite Earth Tub! The Earth Tub is designed specifically for on-site composting of food-wastes. The Earth Tub is a fully enclosed composting vessel featuring power mixing, compost aeration, and biofiltration of all process air. The Earth Tub is capable of processing as little as 40 lbs per day or as much as 500 lbs per day. 

Contact us for more information and to schedule a tour to see the Earth Tub in person!
