RECYCLING
Single Stream Recycling
• If done properly, it will work
• What may be required
– Proper technique
– Capital expenditures
Issues to Address
• Increase in residuals
• Loss of valuable recyclable commodities
• Lost revenue due to downgrade of recyclables
and lost sales opportunities
Value of Paper and PET Recyclables
Value of one metric ton of:
$100 - $125 1
$530 - $570 2

MRF Conditions Affect
Residuals Loss
• The quality of material entering a MRF greatly affects the amount
of residuals leaving the MRF
• Once material enters the MRF, specific conditions at the MRF
greatly affect the amount of residuals leaving the MRF

Recommendations To
Prevent Bottle Loss
• Educate residents so that incoming stream is decent
• Strive to handle the appropriate tons per hour for the MRF
• Adjust belt speed so that fiber piles do not grow too deep, thereby
hiding other recyclables
• Remove film before material goes through the screen
• Add another star screen to single screen system
• Send residuals back through the system

What’s Next?
• Analyze the stream of material from your
community
• MRFs must be designed to handle the planned
incoming stream of material
• Be sure that what is diverted to the recycling
stream can be recycled
