USU Earth Flow system installed in 2015
CLIENT NEED
Utah State University (USU) in Logan, Utah sought an on-site, in-vessel composting system to help it:
- Conduct closed-loop food-waste composting on campus
- Reduce greenhouse gas emissions
- Reduce solid waste and disposal costs
- Reduce costs for purchasing soil amendments
- Provide a high-quality, nutrient-rich soil amendment for campus landscaping and garden beds
USU issued a request for proposals (RFP). After a competitive bid process, they selected the EF-14 Earth Flow system from Green Mountain Technologies.
GMT SOLUTION
This Earth Flow system is approximately 8 feet wide by 14 feet long and can receive up to 840 pounds of feedstock per day (assuming a 21-day retention time in vessel).
Alexi Lamm, Sustainabilty Coordinator at USU recently reported, “It’s been going well. We’re happy with the compost product. The compost will be in flower beds this spring with signs telling students where it came from.”
The following table lists USU’s system requirements and how the EF-14 was able to meet these requirements.
