Campus presenter details three compost streams, collection logistics and odor controls
Summary
A presenter described campus composting operations — composted bedding, regular compost, organic compost — and explained collection methods (small rear-load packer, 24-gallon carts), manual sorting challenges, and biofilter odor-control systems used at the facility.
A campus presenter described the facility's three compost products (composted bedding for animal care, regular compost and an organic compost stream) and the reasons food waste often goes into regular compost rather than organic compost because some collection materials prevent organic certification. The presenter said, "We have 3 different types of compost," and explained that carcasses and certain materials go to the organic compost stream while food waste usually goes into regular compost due to contamination concerns.
The presenter walked the committee through collection operations — small rear-load packers and 24-gallon rolling carts for dining halls — and said staff sometimes have to hand-pick contaminants from incoming loads. The presenter emphasized worker safety improvements over the years and described the site's air-management system: negative-air extraction into a biofilter made of wood chips and finished compost to reduce odors toward nearby towns.
Committee members asked about smell complaints and the presenter said the facility has not experienced community complaints because of those controls and location advantages. The presenter offered to provide annual composting numbers to the committee at a future meeting.
