Single Stream Recycling

• If done properly, it will work

• What may be required– Proper technique– Capital expenditures

* Source: Harman Paper

Issues to Address

• Increase in residuals

• Loss of valuable recyclable commodities

• Lost revenue due to downgrade of recyclables and lost sales opportunities

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
