2. Environmental Products Have Been Used In a Wide Range Of Applications

3. Infrastructure Applications 3 Marine – Tugs - Barges Offshore Drilling Dredging Pile Driving – Cutting - Repair Dewatering Lift Trucks - Vertical Concrete Breaking – Cutting Cranes

4. Dredging Applications 4 Hydraulics Grease Wire Rope Winches Cranes Port Equipment Pumping

5. Only recently have bio lubes been able to withstand the tortures and extremes of modern vessels 5 Long Term Durability Testing Wet and Dry Testing Frequent Retest Requirements Products Disapproved Component Review

6. What are Environmentally Safe Fluids? Readily Biodegradable? Inherently Biodegradable? Environmentally Friendly? Synthetic? Food Grade? Clean? Glycol? Ester? Vegetable?Sheen?

7. Two Tests: Primary Vs. Ultimate Biodegradation Biodegradation Reaction: Lubricant CH+ O 2 + Bugs CO 2 + H 2 O + More Bugs (Biomass) Primary BiodegradationUltimate Biodegradation CEC L-33- A 93OECD 301, ASTM D 5864, ASTM D7373 > 80% >60%

8. Types of Biodegradability Readily Biodegradable Hydraulic Fluids Break Down Over 80% in 21 Days – 60% in 28 Days Inherently Biodegradable Products Break Down… Someday … after fines, cleanup, downtime and environmental destruction!

12. None Inherently NOT BIOGRADABLE HETGVegetable HEPGPAG HEESESTER HEPRPAO and related product

13. Inherently Biodegradable Not Truly Biodegradable Expensive for petroleum

14. Conventional Vegetable Fluids HETG Oxidative Weakness Temperature limitations Life expectancy Hydrolytic Weakness Care must be taken

15. Polyglycol Synthetic (PAG) Fire Resistant Specifically Designed System Not Compatible with Petroleum or Vegetable

16. Synthetic Esters (HEES) Hydrolytic Unstable –“unzips” with water Acid formation Seal Deterioration

17. Ester Chemistry Vegetable Oil + Alcohol + Acid Synthetic Ester + Water + Heat

18. Bio-polyolefin Synthetic (HEPR) Durable Low Cost/Long Fluid Life Separates From Water Good Seal Compatibility Broad Temperature Range

19. Application ClassTypical Performance Seal & Hose Compatibility Water Tolerance LimitationsApplication HETG EL 100 VariesMixedMedium Water, HeatLight Duty, Short change out, low temperature. HEPG EL FR 46 WeakVery PoorMiscible Incompatible with many seal materials. Absorbs moisture. Prices vary Fire hazard, especially designed system HEES EL 2000 MixedVery PoorVery Weak Hydrolyzes in water. Creates acids. Expensive. If dry, high performance. HEPR EL 3000 EL 200 Excellent ExpensiveHeavy duty, chance of contamination

20. Conclusions Making the determination to change to bio lubricants one should consider many factors A bio oil can be more expensive initially but can save money in the long term Bio oils have been proven in the field and can perform as well as petroleum
