Global leader in turf • One of the world’s largest synthetic turf manufacturers with four state-of-the-art plants on three continents. • ISO 9001 Quality Certified, Synthetic Turf Council Certified Manufacturer and a FIFA Preferred Producer • 80 million square feet produced for sports fields, commercial and residential landscape, rooftops and airports in the most demanding climates, from North America to Asia to Europe and the Middle East • Highest Manufacturing Quality Assurance (MQA) processes and procedures at Arkansas and Georgia production facilities. Landscape Sports – Brazil National Training Facility Landscape – Residential/Commercial FIFA Preferred Producer Aviation Turf – US Air Force Academy. 1.4million sf

  3. The Evolution of Environmental Closure Leads to LiteEarth

  4. Side by Side Comparison LiteEarth Traditional • A long-term synthetic grass/EPDM liner closure system for MSW, C&D, Hazardous Waste, Industrial, Monofill, Mining and other environmental applications • Active discussions with regulatory agencies and projects in many states in the U.S., Canada, Europe and Asia

  5. The LiteEarth System Mechanical (Earth) Anchors Durable Synthetic Grass Liner

  6. Key Material and Components • EPDM Geomembrane Liner • Proven material. Over 30 years of application history; billions of square feet have been installed and seamed in all types of environments, including MSW landfills, ash liners, digester caps, rooftops, etc. • Highly resistant to weathering • Impermeable to water • Highly elastic • Key Test Data • ASTM D 1204: 100% better linear dimensional performance than LLDPE • ASTM D 5617: 230% better multi-axial elongation performance than LLDPE • ASTM D 6693: 108% greater elongation than LLDPE • Not affected by Leachate as confirmed by EPA Method 9090A testing

  7. Key Material and Components • Synthetic Turf • Advanced synthetic polyethylene turf yarn and polypropylene 18-pic primary with 4X UV stabilizers than sports field turf • Both fibers and primary independently tested for extreme weathering conditions • Durable, spined monofilament stands up without infill • NO SAND INFILL = NO WIND or WATER EROSION • Stable tuft bind secures turf into system (does not fibrillate) • Minimal annual maintenance, no seeding, mowing, fertilizing, pesticides, watering • Green, sustainable natural looking grass 24/7/365 Monofilament Fiber • Key Test Data • ASTM D 3218: 2X competitive turf thickness (Spine monofilament 200 micron provides greater pigment and UV stabilization in the yarn) • ASTM D 1577: 35% greater yarn weight than competitive fibrillated products • ASTM D 5848: 38% higher pic for the woven polypropylene geotextile • ASTM D 1335: 4X greater pull-force for yarn (>4 lbs/force) 50% Retention Tensile Strength/Color after 50 years (1000 hours = 1 year)

  8. Key Materials and Components • Advanced Composite Adhesive • Automotive proven synthetic elastomer hot melt technology for bonding EPDM and like substrates • Factory bonding of the synthetic grass composite to EPDM through high compression/heated rollers for permanently “welding” of the components • Performed at Act Global’s ISO 9001 synthetic turf manufacturing facility in Calhoun, GA • Key Test Data • Operating range: -40 deg F to 200 deg F • Softens at 250 degrees F • Comparative testing to 60 years • Flash point 400 deg F

  9. Efficient Installation (with earth anchor option) Completed Assembly Job Site Seaming

  10. Key Materials and Components Mechanical Earth Anchors • Reference: Platipus Anchors (http://www.platipus-anchors.us/) • Anchors spaced parallel along the seam and covered by adjacent roll • Quick and easy to install for maximum, certified load lock • Adjustable site specific depth and lock back options • HDPE plate with stainless steel cable and anchor available Pull test using metal 5.9” plate achieved an ultimate load greater than 1,300 lbs force

  11. System Design and ApplicationCross Section with Anchoring System

  12. Proven Seaming Technology • LiteEarth Liner Roll size: 15’ x 100-260’ w/14” (for mechanical anchors) or 7” wide “tail” for seaming • LiteEarth Liner Weight: 8.8 oz/sf • 7 inch high-performance splicing tape • Industry proven bonding adhesive technology with rapid flash-off and curing cycle ¹45 mil non-reinforced EPDM seamed to polypropylene primary, as tested by TRI ²50 mil textured HDPE, GM13 ³50 mil textured LLDPE, GM19

  13. System Design and Application Cross Section Prior to Bonding with Anchor Installed

  14. System Design and Application Cross Section of Completed System

  15. LiteEarth – Extensively Tested • Synthetic grass fully tested for stability, longevity and performance in the most demanding environments • MQA (Manufacturing Quality Assurance – Firestone and Act Global) • Composite tested by accredited, independent laboratories for: • Thickness • Tensile properties • Puncture resistance • Linear Friction • Tear resistance • Multi-axial tensile • Methane gas permeability • Seam peel and sheer • Ply adhesion • Comparative interface friction • Falling head permittivity • UV weathering

  16. Test performance comparison ¹LiteEarth consists of a 45 mil non-reinforced EPDM liner factory bonded to a 4.4 oz/sy, ½” tufting gauge single layer 18 pic woven polypropylene primary ²45 mil, non-reinforced EPDM per GSI GM21 ³50 mil textured HDPE, per GSI GM13 ⁴50 mil textured LLDPE, per GSI GM17 ⁵Testing conducted by TRI - Primary rupture / EPDM rupture ⁶Testing conducted by TRI (available upon request)

  17. EPDM Long-Term Performance Predicted Geomembrane lifetimes based on 50% reduction of strength and/or elongation. Note: Tested as an Exposed Geomembrane* *LiteEarth’s 45 mil EPDM is covered by a compound adhesive, a UV stabilized primary and high-grade monofilament turf that reduces the amount of UV exposure to the EPDM Source: http://geosyntheticsmagazine.com/articles/1012_f3_landfill_covers.html

  18. Pricing/Feasibility • Assumptions: • 1 Acre • Subgrade: free of aggressive angle changes, ruts, loose stones in excess of 3/8” and small cavities. Compacted to 90-95% Standard Proctor Density (not included in cost) • Final layer: Layer of sand and/or geotextile underlayment of at least 8.0 oz/yd2 (not included in cost) • 15’ linear earth anchors • 20 pipe flashings • Further cost reductions (in material) are possible based on volume • Maintenance = • LiteEarth: $50/acre/year • Traditional: $400-1900/acre/year for traditional • Competitive turf systems with infill: est. $500/acre/year High performance closure providing net present value cost savings at closure and post-closure

  20. Summary • An advanced, engineered and fully-tested environmental closure system providing equivalent infiltration and erosion protection for a Final Cover as specified in RCRA Subtitle D (Part 258 Subpart F, Section 258.60 for MSWLFs) – but is also well suited to monofil and similar applications • The system’s higher tensile strength is beneficial for wind uplift protection and steeper side slopes • Lower system elongation minimizes field-induced wrinkling • Also provides airspace benefits at full elevation and side slopes • 30 year permeability and performance warranty
