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:
Newsprint: $100 - $125 1
PET: $530 - $570 2
In California, value of one metric ton of:
Curbside PET: $2,066 3 (CRV + processing payment)

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
– Is the MRF a protected structure? – How the material is dumped on MRF floor– Is the material presorted?– Wet conditions– How many screens are used? – The size and depth of the sort stream– Speed of sorting belts

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
