  • Slide 3
  • Useful Metric Conversions 2000 Mockingbirds 1 millionth of a fish 4 nickels = two kilomockingbirds = 1 microfiche = 1 paradigm
  • Slide 4
  • Why Biobased Floor Stripping May 2002, Section 9002 of the Farm Security and Rural Investment Act (Public Law 107-17) 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
  • Slide 5
  • 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. www.ofee.gov/gp/USDA_Secretary's_Memo.pdf
  • Slide 6
  • Whole or Significant Part What does that really mean? Lab set up four categories Whole100% Significant50% Partial25% Minimal
  • 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 0-2410 25-499 50-748 75-996 100-1495 150-1994 200-2993 3002 >3000 Screening Values

  • 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
  • Slide 19
  • 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
  • Slide 20
  • 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

  • pH Neutral substances receive the highest Individual Indicator points Both very acidic and very basic are both avoided pHPts 0-1.00 1.1-2.44 2.5-2.96 3.0-4.07 4.1-5.98 6.0-6.49 6.5-7.510 7.6-8.99 9.0-9.98 10-11.47 11.5-11.96 12-12.44 12.5-12.92 13-140
  • Slide 22
  • Example Safety Screening Results
  • Slide 23
  • 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 higher Safety Screening Scores TURIs 5 Chemical Assessment
  • Slide 24
  • Lab Testing Bench scale testing PPreliminary screening MManual wipe MMechanical abrasion SSee handouts Pre-pilot testing FFloor stripping machine
  • Slide 25
  • Field Testing Top performers used on site Work completed by hospital staff Witnessed by Lab staff Survey of work process During stripping with existing solvent With biobased alternative
  • Slide 26
  • Evaluate economics Product cost Current solvent from the paper Found to be the cheapest product Operating cost Initial biobased alternatives required longer times Some needed to be heated Environmental cost Current solvents components linked to significant negative health, safety, and environmental impacts
  • Slide 27
  • Recommendations TURIs Plan Work with Bedford facility to implement biobased floor stripping products VAs End Goal Take results and assist in the adoption with all of the VA Hospitals
  • Slide 28
  • Finishing Work with VA Phase 2 of project Hard surface cleaning Floor & wall Completion of both phases by December 2 Case studies 2 Executive summaries
