3 Why Biobased Products May 2002, Section 9002 of the Farm Security and Rural Investment Act (Public Law ) –Federal agencies are mandated by this law to purchase and promote the purchase of biobased products United States Department of Agriculture –Memorandum in January of 2005 –Establishing the USDA biobased procurement program –Intent to increase the purchase and use of biobased products by Federal Government

4 What is Biobased A biobased product as defined by the Secretary of Agriculture –To be a commercial or industrial product (other than food or feed) that is composed, in whole or in significant part, of biological products or renewable domestic agricultural materials (including plant, animal, and marine materials) or forestry materials.

5 Whole or Significant Part What does that really mean? Lab set up four categories –Whole100% –Significant≥50% –Partial≥25% –Minimal<25% must be greater than 0% This is where we want to be

6 Biobased Sources General source of materials in products –Soy –Corn –Plant –Citrus –Other

7 Compare Current Products with Alternatives Evaluate traditional cleaning products for performance under controlled setting Evaluated bio-based alternatives under laboratory conditions as well –Green Seal GS37 certification process Industrial and Institutional Cleaners –Green Seal GS40 Industrial & Institutional Floor-Care Products

8 Find Out What Your Potential Applications Are Identify potential areas for using biobased products –All purpose cleaning –Hard surface cleaning –Glass Cleaning –Carpet Cleaning –Floor finish & stripping –Vehicle maintenance

9 Start Small Pilot on One Possibility –Floor Stripping and Cleaning

15 Product Profile

16 Laboratory Testing Floor Finish Stripping

17 Lab Testing Floor Finish Stripping Bench scale testing –P–Preliminary screening –M–Manual wipe –M–Mechanical abrasion –S–See handouts Pre-pilot testing –F–Floor stripping machine

18 Screening Floor Finish Stripping Have identified over 50 possible biobased products Established a screening process to aid in the identification of products that may be effective –Necessary as many of the identified products were not manufactured for floor stripping applications –Generally designed to remove other types of coating systems

19 Screening Results Floor Finish Stripping Reduced the number of possible products down to 20 –Half of were very effective –Half were partially successful

20 Bench Testing Floor Finish Stripping Vinyl composition floor tile Scrub pad Stripping was performed at 175 rpm –Using pad attached to variable speed drill 15 effective products –Some had strong odors

27 Evaluate EH&S

28 EH & S Comparisons Current Product Top alternative products evaluated in the lab and on-site –SSL’s Safety Screening –TURI’s Pollution Prevention Options Analysis System (P2OASys)

29 Lab Safety Screening EHS analysis –Based on 5 parameters Volatile Organic Content (VOC) Global Warming Potential (GWP) Ozone Depletion Potential (ODP) National Fire Protection Association hazard rating (NFPA) or Hazardous Material Information System ratings (HMIS) pH –Provides quick screening of cleaning alternatives based on SSL’s focus

30 VOCs Source control –Eliminate products that have high levels of VOCs –Purchase new products that contain low or no VOCs (Environmentally Preferable Purchasing) VOC content (g/l) Pts >3000 Screening Values

31 GWPs Some greenhouse gases occur naturally in the atmosphere –Include water vapor, carbon dioxide, methane, nitrous oxide, and ozone Others result from human activities –Very powerful greenhouse gases that are generated in a variety of industrial processes, including cleaning processes GWP ScorePts GWP = 010 GWP = 1 (CO2)5 All others =0

32 ODPs The ratio of the amount of ozone depletion of a chemical compared to the amount of ozone depletion of the same mass of CFC-11 Certain manufactured substances can destroy stratospheric ozone much faster than it is formed ODP PointsPts ODP = 010 All others =0

33 HMIS/NFPA Individual Indicator Scores –Add up HMIS/NFPA for each category –Use table to determine the number of points to assess HMIS/NFPA Point Assessment TotalPtsExamples 010 H-0 F-0 R-0 19 H-0 F-0 R-1, H-0 F-1 R-0 28 H-1 F-1 R-0, H-2 F-0 R-0 37 H-1 F-1 R-1, H-2 F-1 R-0 32 H-3 F-0 R-0 46 H-2 F-2 R-0, H-1 F-2 R-1 41 H-1 F-3 R-0 55 H-2 F-2 R-1 50 H-1 F-3 R-1, H-2 F-3 R-0 64 H-2 F-2 R-2 60 H-3 F-3 R-0 7, 8, 90 H-3 F-3 R-1, H-3 F-3 R-2

34 pH Neutral substances receive the highest Individual Indicator points Both very acidic and very basic are both avoided pHPts

37 Safety Screening Should not be concluded from these results alone that all biobased products are safer with respect to EHS A full EHS study should be conducted on the products with better Safety Screening Scores –TURI’s 5 Chemical Assessment –P2OASys

38 Pollution Prevention Options Assessment System P2OASys –Helps companies determine if TUR options being considered have any unforeseen negative environmental, worker or public health impacts –Specific process information used to establish baseline of hazards associated with current system

61 Next Steps TURI’s Plan –Work with facility to implement biobased floor stripping and hard surface cleaning products Facility –Identify next focus area and repeat process

62 Future Work Several projects that could be conducted to increase the amount of biobased products being purchased –Evaluation of biobased floor finish or other “green” finish can be tested So that lower dilutions of biobased floor strippers could be used effectively thus reducing operating costs further –The expansion of biobased cleaning products beyond the floor finish stripping and hard surface cleaners would be a logical next step Glass cleaning Bathroom cleaning All purpose cleaning activities Cleaning of equipment and transport vehicles during maintenance and repairs
