The Waste Audit Process
• We collect the landfill
waste from buildings
and bring it back to the
office to sort.
• We sort into six
categories: Cardboard;
Mixed Paper; Metal and
Glass; Landfill; All
Plastics; and Compost

Areas of Improvement
• Enclose Odor
• Compost < 24 Hours =
Stinky
• Students in the LAEP
studio removed the
compost container and
covered up the opening.
We made lids in the Shop.

Container Aesthetic
• This is the Design School!
• Top of header board does
not line up with concrete
wall behind it
• Dean did not like big
plastic box in entry lobby
• Solution is to clad waste
cabinet with nicer looking
material/Flat headerboard

Lessons Learned
• Open Compost Container in Closed Space will
Smell
• Aesthetic matters in high visibility space
• Sorting waste takes time
• Compost is a major component of the waste
stream
• Five is the magic number of people
