Lab Brown Glass

Brown Glass Recycling Rules and GuidelinesIt is very important that labs follow the rules on the signage at right to recycle brown glass so we ensure we are able to keep this recycling opportunity! Click on the yellow sign for further details. The rules are similar to those for the lab metal container recycling. Do not place lab brown glass in regular container recycling recepticals around campus. They are a contaminant. 

Lab brown glass collection containers located at:

  • Cristol Chemistry (toters located in basement)
  • Jennie Smoly Caruthers Biotechnology Building (toters at caged loading dock)
  • Satellite collection areas at:
    • SEEC loading dock
    • MCDB Stores in the Gold Building​

Where does it go?

→ Our lab brown glass is collected by a local company Clear Intentions and processed into new glass bottles, terrazzo (a durable type of flooring) and fiberglass insulation.

 


Lab Paper Towel Composting

Lab Compost Half Sheet imageLab paper towel composting is now available in any building on campus that has composting in the building restrooms. New buildings are being added all the time. The program includes any paper towels that would normally go into the trash, but not paper towels that are contaminated with hazardous chemicals, radioactivity, or biohazardous materials which need to be properly disposed of as hazardous waste. CU Green Labs can distribute 6 gallon collection containers free of charge to labs interested in participating. Lab members are responsible for taking their lab's paper towels to their lab paper towel composting containerbuilding's bathroom/restroom when their collection container is full.

Currently available in:

  • Jennie Smoly Caruthers Biotechnology Building
  • Ramaley
  • Gold
  • Porter
  • Wilderness Place

Where does it go?

→ Compost from CU Boulder is hauled to A1 Organics in Keenesburg, CO

 


#6 White Block Foam

#6 White Block Foam Instructions for RecyclingOnly #6 expanded polystyrene (EPS) can be recycled through CU Green Labs. To test whether yours is the correct kind of foam, try pulling a few beads off the foam with your finger. If you can and the foam is white (not black, not grey), then you can recycle it. If you can't peel beads off with your finger, it is a different kind of plastic foam and must be put in the landfill dumpsters at this time. Please remove all tape and labels from foam before placing it in the recycling carts.

White block foam collection carts are available at:

  • Gold/Porter building junction in NE corner, on the basement "B" level
  • Muenzinger lobby just off Colorado Ave
  • Muenzinger D00 level right outside elevatorPicture of piled up white block foam
  • Ramaley 1st floor, east side of building near the teaching labs
  • JILA 2nd floor main hallway
  • JILA basement in the X wing
  • RL4 on East Campus
  • Wilderness Place near the loading dock on 1st floor
  • JSCBB on each floor of the building
  • SEEC/MacAllister loading dock (C184)
  • SEEL in the Recycling Rooms on 1st, 2nd, and 3rd floors (Rooms 196, 289, 389)
  • USGS (RL6) near loading dock

Where does it go? 
→ From Eco-Cycle it becomes interior paint-grade architectural molding, such as baseboard.
