VI Background and Mission The Vinyl Institute, founded in 1982, is a U.S. trade association representing the leading manufacturers of vinyl chloride monomer, PVC resin, vinyl additives and modifiers. VI Mission To advocate the responsible: – manufacture of PVC resins and compounds – life cycle management of vinyl products – promotion of the value of vinyl materials to society Vinyl is Widely Used in Building and Construction: Additional Organizations Involved with Vinyl Product and Additive Manufacturers • • • • • • • • • • • American Architectural Manufacturers Association Vinyl Siding Institute Fence, Deck and Rail Association Moulding & Millwork Producers Association Plastic Pipe & Fittings Association Uni-Bell PVC Pipe Association Chemical Fabric and Film Association Wallcovering Association Resilient Floor Covering Institute Global Vinyl Council, ECVM, VCC, JVC, VCA, & Others American Chemistry Council – Plastics Division, Chlorine Chemistry Division Building Certification Programs that Include Recovery and Recycling Standard Category Green Globes Pollution (emissions, solid waste, effluents) Green Globes Material/Product Inputs GBI™ Pollution Draft ANS 01- (emissions, solid 2008P waste, effluents) LEED® LEED® LEED® LEED® Material and Resources (MR) Material and Resources (MR) Material and Resources (MR) Material and Resources (MR) Sub Category E.5 Reduction, Reuse, and Recycling of Demolition Waste E.2 Minimal Consumption of Resources Requirement Award Implement a construction, demolition, and renovation solid waste management plan 5 points Specify materials with recycle content 10.5 Reduction, Reuse, and Recycling of 25% or more of C&D was Demolition Waste diverted from Landfill 2.1 Construction Waste Management Divert 50% from Landfill 2.2 Construction Waste Management Divert 75% from Landfill 10% Post-consumer + 1/2 Pre-consumer 4.1 Recycled Content 20% Post-consumer + 1/2 Pre-consumer 4.2 Recycled Content 3 points 2 to 6 points 1 point 2 points 1 point 2 points Proposed Building Codes that Include Recovery and Recycling Standard Category Material and IGCC Waste Recovery Material and IGCC Waste Recovery Material IGCC Properties IGCC Material Properties Sub Category Requirement Award 502.1 Construction Recycle or Salvage 35% of NonMaterial and Waste Hazardous Waste N.E.

Carpet with Post Consumer Recycle Content Vinyl Backing Vi Suggested Guidelines To Consider for Reclamation of Vinyl Plastics Understand your purchaser’s requirements – Know what materials are contaminants and what their capabilities are to handle contaminants. Photos and samples are helpful. Sort and Separate – Purity is key to recycler. One thermoplastic while recycleable by itself is typically considered a contaminant if mixed in with another thermoplastic. Finer separation allows greater ability to successfully recycle the material, <0.5% non-melts Keep the material Clean – Fewer contaminants (rocks, dirt, trash, wire, paper, glass, bottles) are always preferable, <0.5% non-melts Bale the Separated Materials – Densify material for trucking longer distances, allows for final sort before processing steps Create Full Truckload Quantities of a Separated Material – Partial loads increase shipping expense Where to Begin: The Low Hanging Fruit Installation Drops and Cutoffs from construction or renovation Typically less contaminated e.g. no caulking or fasteners Less comingled plastics More identifiable plastics Manufacturer take back programs often available Set up designated roll-offs at job sites to begin sort process as scrap is generated Sortation Can Begin On the Job Site with Designated and Identified Bins (Courtesy: Wisconsin Waste Cap Project) The Next Frontier: Deinstallation/Demolition Materials Tough to Recycle Due to: Difficult contaminants e.g. caulking and nonmetallic fasteners Frequent comingled plastics Plastics identification can be challenging Manufacturer take back programs often for just their product Fewer reprocessors due to limited clean up capabilities Full truckload quantities are required for economical shipping Reprocessing Reclaimed Vinyl Materials Understand needs of market: Amount of contaminants allowed, form required, restricted materials, colors, resin compositions, etc. Dry Processing: Typically involves debaling, hand sort, shredding, metal removal, granulating, dedusting, but decision to pulverize depends on customer’s ability to handle powders Wet Processing: May be necessary to remove dirt, but drying product to <0.5% moisture content adds cost Melt Filtering: Produces high quality product, but practical incoming contaminant level is <0.5% Blending: Minimizes variability across a truckload Clean Rigid PVC Recyclate Product Photo Courtesy of RPG Regrind for Single Screw Extrusion Blended Powder for Twin Screw Extrusion Where to Find Vinyl Recyclers • Vinyl Institute Recycling Page: The Vinyl Institute maintains a directory on its web site at: www.vinylinfo.org/Recycling.aspx • Vinyl Recyclers Directory lists over 70 companies involved in vinyl recycling services spread out geographically across the U.S. and Canada • Directory for Manufacturers lists over 80 manufacturers who make products using recycled vinyl spread out geographically across the U.S. and Canada.
