1. Challenges Facing MRFs: Material Flow Study Resa Dimino Director of Public Policy 26 th Annual NYS Recycling Conference November 6, 2015

2. Promoting and Protecting the PET Package Introduction to NAPCOR NAPCOR is the trade association for the PET packaging industry in the United States and Canada 50 members encompass all parts of the PET value chain from resin production to end of life/recycling NAPCOR’s priorities are to: – Promote the introduction and use of PET packaging – Overcome hurdles to introduction, use and recycling of PET packaging – Communicate the attributes of the PET container as an environmentally sustainable package 2

7. Goals Why? The material mix at the MRF is constantly changing Understanding how categories of materials flow will help the industry improve recovery 7

8. Methodology 8

9. MRFs Tested (5) 9

10. Paper Materials Plastic Materials 10 Gable-top and aseptic cartons Beverage cups (hot/cold) Ice cream containers Clamshells Trays Bottles & Jars Small/Large plastic containers Small/Large plastic lids Clamshells/Domes/Trays Beverage Cups

11. Two Types of Analysis Where did study materials end up? 100 PET cups What was in each of the target bales? nHDPE Bottles cHDPE Bottles Trash Other 11 PET Bale (80) Mixed Plastic (6) Mixed Paper (7) Residue (7) nHDPE Bale

12. Product Characterizations were Calculated for: Mixed Paper Mixed Paper Newspaper cHDPE Newspaper PET nHDPE CartonsMixed Plastics Residue 12 1.Some facilities only marketed one grade of paper 2.Also included a HDPE/PP Tubs and Lids grade 1 2

13. What Did We Learn? 13

14. Screen maintenance is key to consistent performance Clean screens of material that are wrapped around the shafts Replace worn and damaged discs More screens produced better separation Large facilities both had 1 extra screen than medium facilities and had lower loss rates of plastics to the paper stream Likely reasons for high loss: 8% loss at large facility had unusually compacted and wet material due to equipment failures and snowstorms 12% loss at both medium facilities likely had worn disc screen discs Material preparation had a strong effect Minimize compaction of material by residents and collection trucks Keep material dry Avoid overloading screens past their design throughput Overall loss rates of plastic materials varied from 3% to 12% 14

15. No material is perfect Even plastic bottles had on average 5% loss to the paper stream Rounder materials like cups, containers and bottles had lower average loss rates than square materials like clamshells and cartons Materials that held their shape had a higher tendency to flow to the container line than those that flattened Lightweight water bottles had a loss rate of 15% Loss rates above are to the paper stream only, each type also had losses to other commodities and to the residue 15 Loss rate of packaging materials to the paper streams

16. Increasing benefits as stream evolves into being more diverse and lightweight Manual sorters can be overwhelmed by number of individual pieces and confused by similar looking resins or packages (i.e. clear PET and clear PP) 16

17. Factors Improving a Package’s Recovery 17

18. Example Results 18

19. Where Did the Material End Up PET Bottles – Small (< 1L), regular weight Size – not too small Holds 3D shape relatively well Very common material in the MRF cHDPE Bottles - All Size – noted numerous small single serving type bottles Holds 3D shape relatively well Very common material in the MRF 19 Small, regular weight PET beverage bottlesAll CHDPE bottles

20. Size – many small containers More likely to flatten due to open top Very common material in the MRF Size – noted numerous small single serving type containers More likely to flatten due to open top Very common material in the MRF, but easily confused with PP containers 20 Where Did the Material End Up Small PET ContainersAll CHDPE Containers

21. Size – not many small school milk cartons observed Holds 3D shape relatively well Smaller percentage of overall stream Size – not too small More likely to flatten due to open top Not currently accepted by any of the test MRFs 21 Where Did the Material End Up CartonsPaper beverage cups

22. Conclusions Each player in the recycling value chain has a role to play to improve recovery Packaging Designers Design with recovery in mind Municipalities Work with MRFs to add new materials and educate residents on proper material preparation MRF Operators Adequate separation equipment and continual maintenance improves separations 22 MRF Equipment Designers Research designs to improve separation of new materials
