Sustainability: Waste Diversion

The CSU Sustainability Policy calls for HSU to reduce its solid waste disposal rate by 80 percent by 2020, and then move to zero waste by reducing the amount of waste sent to the landfill to zero. The amount of landfill waste generated on campus continues to decline each year. Since 2012, the amount of waste HSU sends to the landfill has dropped by 23%. Because everything from food waste to computers to office furniture gets reused and recycled, HSU has won a number of awards for its waste reduction efforts, including a 2012 CSU Energy Efficiency and Sustainability Best Practices Award for its food waste diversion program, and as the winner of the 2014 national recycling competition Game Day Challenge in the "National Diversion Rate" category. 


All plastic containers numbered 1 through 7, metals, aluminum foil, glass, as well as paper, magazines, and cardboard can be thrown together into any bin labeled "recycling" on campus. You can also throw rigid plastics, like buckets and laundry baskets, into the recycling dumpsters.  We also accept clear film plastics (e.g, shrink wrap, clear plastic bags) in our recycling bins.

Electronic Waste (E-waste), Batteries, Discs, Printer Cartridges and CFLs Collection

E-waste is the name given to electronic products nearing the end of their "useful life." Computers, televisions, VCRs, stereos, copiers, cell phones, mp3 players and fax machines are common electronic products. Recycling bins for these items are conveniently located across campus.

  • 2nd floor of the Jolly Giant Commons
  • Inside the main exit of the Library
  • Inside the UC Lounge

  • Outside Warren House 53 R.O.S.E office


Composting and Food Waste Collection

With your help, HSU is keeping close to 150 tons of food waste and compostable materials out of the landfill each year! There are now even more food waste collection containers conveniently located on campus:

  • At the entrance to the Depot and inside the Depot
  • On the University Center Quad
  • Main entrance to the library and in the Library Cafe
  • At the main entrance, behind and inside the South Campus Marketplace
  • At the main entrance to BSS
  • In green wheeled totes at all residence hall trash and recycling areas

All these containers accept biodegradable materials such as coffee grounds, soiled paper products, eggshells, fruits, vegetables, legumes, and grains. Meat and Dairy are OK! No plastics or Bio-plastics please.


Of this organic waste 8,000 pounds stays on campus and is composted by WRRAP to produce soil amendment for the campus grounds and CCAT.  The remainder of the biogenic waste produced on campus resides in an in-vessel composting system before it is taken to a vermi-composting operation off campus.
