Questions: How has single stream changed the dynamic
of the recycling industry? How and why are recycling programs making
the switch to single stream?
Explore: The impact that single stream is having Best Management Practices for the single
stream age

Overview Why Single Stream Matters Looking at the Results Curbside Recycling and Carts Drop-off Recycling and Compactors Expanding Access to Single Stream Recycling BMPs Some Thoughts about Glass

Why is Single Stream So Significant?
Collection is the most expensive aspect of providing recycling service
Single stream recycling enables more efficient collection for both drop-off and curbside programs
Ability to commingle removes a barrier to participation
Change to single stream is associated with significant increases in participation and diversion

Carts Matter
NC Recycling Program Collection Averages (FY 2010-11)
Bin-based Programs 247 lbs / household
Cart-based Programs 445 lbs / household
![Page 11: Single Stream Recycling ~exploring the impact~ Rob Taylor NC Division of Environmental Assistance and Outreach](https://reader033.vdocuments.net/reader033/viewer/2022061305/5513f3015503463a298b60f9/html5/thumbnails/11.jpg)
Cart-Based Collections Enabled by single-stream processing Make automated collection possible Make use of RFID systems possible Reduce work-related injury Increase ease for citizens Increase capacity for storing recyclables (18 gal vs.
95 gal)
Easier to add new materials to program Make every-other-week collection less
problematic Business case: ROI~ 5 to 7 years, can be even
quicker

Single-Stream and Drop-off Recycling Simplify – no need for sorting Fewer containers taking up less space Allows for compaction to maximize hauling efficiency Counties should strongly consider compactors at
staffed convenience sites (more payload, fewer hauls)

MRFs Make Single Stream Possible
Recent additions to MRF landscape serving NC: • American Recycling in Asheville, NC; Bay Disposal in Hampton, VA• Benfield Sanitation MRF in Mooresville, NC; North Davidson MRF in Lexington, NC• Sonoco MRF in Jacksonville, NC, Waste Management in Winston-Salem, NC
![Page 16: Single Stream Recycling ~exploring the impact~ Rob Taylor NC Division of Environmental Assistance and Outreach](https://reader033.vdocuments.net/reader033/viewer/2022061305/5513f3015503463a298b60f9/html5/thumbnails/16.jpg)
Hubs & Spokes: Transfer Systems Help Communities Access MRFs
= accessible single stream MRF
= transferring county = good candidates for transfer

BMPs for Single Stream Programs
Carts for curbside programs Compactors for drop-off systems (when practical) Don’t miss the chance to add materials to your
program: All grades of paper? Gable-topped and Aseptic Cartons? Non-bottle Plastics?
Think of the future when buying / replacing equipment: Automated or semi-automated collection using one staff RFID in carts & readers on new trucks
Refresh your PR when making program changes Don’t forget to track program data

What’s This?
![Page 19: Single Stream Recycling ~exploring the impact~ Rob Taylor NC Division of Environmental Assistance and Outreach](https://reader033.vdocuments.net/reader033/viewer/2022061305/5513f3015503463a298b60f9/html5/thumbnails/19.jpg)
Single Stream and Glass Glass can impact the quality of materials
produced by single stream systems
MRF operators love to complain about glass: Issue 1 - Equipment wear and tear Issue 2 - No profit for MRF in handling glass
Not all MRFs are created equal when it comes to the quality of glass produced
![Page 20: Single Stream Recycling ~exploring the impact~ Rob Taylor NC Division of Environmental Assistance and Outreach](https://reader033.vdocuments.net/reader033/viewer/2022061305/5513f3015503463a298b60f9/html5/thumbnails/20.jpg)
More on Glass Glass recycling really matters to:
Glass bottle producers Glass Cullet Recyclers (Reflective Recycling, Strategic
Materials) Consumers (who want convenient glass recycling)
System Cost of Glass Recycling vs. Cost of Glass Disposal
Solutions? Communities can keep glass separate, maybe… MRFs can get better at handling glass, maybe… End users can pay more for recovered feedstock,
maybe…

Conclusion: Single Stream is Advancing Recycling in the Carolinas.
Let’s make it work!
