3. LEVITAN, CORNELL UNIVERSITY Topics What is recycling? Challenges to recycling horticultural plastics. Overcoming the challenges. Products made with recycled horticultural plastics. By whom? What I hope to learn from growers. 3

5. PLASTICS RECYCLING CONFERENCE 2014 – LEVITAN, CORNELL UNIVERSITY 5 Plastics-to-Oil HEAT + PRESSSURE ( + catalyst)  oil or wax + inorganic residue (e.g., carbon black)

6. LEVITAN, CORNELL UNIVERSITY 6 Waste-to-Energy ≠ RECYCLING ENERGY RECOVERY BY INCINERATION (COMBUSTION AT HIGH HEAT) Graphic: SICK Sensor Intelligence. http://www.sick.com/group/EN/home/solutions/industries/waste/Pages/waste.aspx United States: 67 large Municipal Solid Waste incinerators + several hundred industrial, medical and hazardous waste incinerators of all sizes (Source: Waste Incineration. Unites States Response to UNEP Questionnaire for Paragraph 29 Study, Enclosure 4a, Rev. May 2010) Organic waste  inorganic ash, flue gas + heat

7. LEVITAN, CORNELL UNIVERSITY 7 Fuel Pellets PLASTIC PELLETS or 10% PLASTIC + BIOMASS  burns hotter, flows better

9. PP bulk bags LEVITAN, CORNELL UNIVERSITY Horticultural Plastics Many different film and rigid products. Many colors, multi-colored. Different resins, & mixes of resins, with additives. Mostly low density PE, but also HDPE, PP, PS. PVC used historically; some still used, particularly in imported products. 9 Greenhouse & tunnel covers Mulch film Plant pots, flats, trays: PE, PP, PS

11. Challenges to recycling: characteristics inherent to complex, technical products Thin films with multiple extrusion layers, each with additives and colorants for specific agronomic or horticultural purposes: Block UV Repel insects Absorb or reflect heat EVOH O2 barrier Hold moisture Reinforce structure Prevent backwash Stretchability Stickiness Tensile strength Flexibility Rigidity Longevity Degradability LEVITAN, CORNELL UNIVERSITY 11 John Deere Max-Flat PE irrigation drip tape Jphn Deere Pro-Flat PVC drip tape

Lays on soil, gets very dirty. White, black, silver, occasionally clear or other colors. Sometimes 2+ color layers. Some with nylon or EVOH O 2 barrier layer. Photo: Sky Plastics

17. Pesticide containers, chemical drums. HDPE. Example of Extended Producer Responsibility (EPR): Ag Container Recycling Council (ACRC) financed by pesticide manufacturers and distributors. ACRC protocols require triple rinsing, special handling & approved end-uses that minimize exposure. ACRC oversees a national network of collectors, processors, end-product manufacturers. 10 million lb collected 2014; 150 million lb since began in early 1990s.

21. Best Management Practices (BMPs) What not to do! Keep plastic clean and dry as possible Shake out pebbles & clumps of soil Roll or fold into pillow-sized bundles Store off ground, out of mud, grit, gravel Separate plastic by color and type 21 LEVITAN, CORNELL UNIVERSITY 21 Photo: Jim Zecca.

22. Greenhouse, hoophouse, high tunnel covers Clear or white sheets of (L)LDPE. Excellent quality for recycling. Challenge: Keep clean & remove efficiently, meeting needs of growers & recyclers Photo: Lois Levitan, RAPP LEVITAN, CORNELL UNIVERSITY

25. Challenges to recycling: Cost & logistics of collection and transport from fields or nurseries, etc. to recycling markets In most of the U.S., agricultural plastics are dispersed acrosss the rural landscape  high costs of collection LEVITAN, CORNELL UNIVERSITY 25 Difficult to amass full 40,000 lb truckloads

26. LEVITAN, CORNELL UNIVERSITY Why should society & recyclers care about this particular set of plastics? Less than 2% of plastic discarded in US, but possibly 10% of film* Very visible 2-10% When left in the fields catches in bushes, ditches, ravines Alternatives to recycling not pretty: burning, burying in fields bad for air & water quality Landfilling costly to society Societal value of recycling >> economic value: All society benefits from conservation of resources & energy. 26 Plastic discarded in US Agr film *based on VT data calculated by Annie Macmillan, VT Agency of Agriculture.

27. LEVITAN, CORNELL UNIVERSITY Agricultural Plastic Recycling Markets: Processors (Reclaimers) & Manufacturers 27 Domestic markets can & do process used horticultural plastic. Location. Location. Location. More options, less costly to recycle where farms (& plastic use) are concentrated: FL, CA. Smaller, regional recycling markets important for co-mingled supply from less concentrated areas. Some recycling markets vertically integrate to guarantee supply & increase efficiency. Some pick up & some require drop-off. Only a few pay for material. Some take-back products after use & give credit on purchases. Recycling markets typically put < value on difficult-to-recycle plastic than it costs to collect & transport.
