  1. Bio-based Floor-Stripping Jason Marshall Investigating the ecological, health & safety implications of using bio-based floor strippers Or something like that

  2. 2000 Mockingbirds 1 millionth of a fish 4 nickels = two kilomockingbirds = 1 microfiche = 1 paradigm Useful Metric Conversions

  3. 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

  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. www.ofee.gov/gp/USDA_Secretary's_Memo.pdf

  5. This is where we want to be Whole or Significant Part • What does that really mean? • Lab set up four categories • Whole 100% • Significant ≥50% • Partial ≥25% • Minimal <25% • must be greater than 0%

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

  7. Journal of Environmental Health Article May 2007 • From work conducted in 2005 • by Ephraim Massawe • Part of doctoral dissertation • 2nd Article on performance comparison • Journal of Cleaner Production (not publication date yet)

  8. Journal Article Context • Preliminary work with the VA • Identify potential areas for using biobased products • All purpose cleaning • Hard surface cleaning • Floor stripping • Vehicle maintenance

  9. Pilot Study • Biobased Products Pilot Study at the Edith Nourse Rogers Memorial Veterans, Bedford, MA • Two Areas of Focus • Floor Stripping • Hard Surface Cleaning

  10. Process • Product Identification • Lab Testing • Field Testing • Evaluate Economics • Recommendations for Change

  11. Biobased Product Identification • Existing floor strippers • Not many out there • Lab’s website: www.cleanersolutions.org • Wax removal • Coating removal • Web Search

  12. Lab’s Website

  13. Partial List of Possible Floor Strippers

  14. Product Profile

  15. Lab Safety Screening • EHS analysis • Based on five parameters • VOC • GWP • ODP • HMIS/NFPA • pH • Provides quick screening of the EHS impacts of cleaning alternatives

  16. Source control Eliminate products that have high levels of VOCs Purchase new products that contain low or no VOCs (Environmentally Preferable Purchasing) Screening Values VOCs

  17. 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 GWPs

  18. 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 ODPs

  19. Individual Indicator Scores Add up HMIS/NFPA for each category Use table to determine the number of points to assess HMIS/NFPA

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

  21. Example Safety Screening Results

  22. 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 • TURI’s 5 Chemical Assessment

  23. Lab Testing • Bench scale testing • Preliminary screening • Manual wipe • Mechanical abrasion • See handouts • Pre-pilot testing • Floor stripping machine

  24. 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

  25. 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 solvent’s components linked to significant negative health, safety, and environmental impacts

  26. Recommendations • TURI’s Plan • Work with Bedford facility to implement biobased floor stripping products • VA’s End Goal • Take results and assist in the adoption with all of the VA Hospitals

  27. 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

  28. CleanerSolutions • Anyone want to see it? • Anyone? • Anyone? • Class? • Anyone? • Anyone? • Bueller? • Bueller? • Bueller?
