PrecastAn Eco-friendly option? Jim Lewis, RA, LEED AP ASTM E60 Sustainability October19, 2009
LCA and Precast Why is an LCA important? What will PCI and the industry do with the results? Will we be transparent?
Greenwash (grenwosh,-wôsh) – verb: the act of misleading consumers regarding the environmental practices of a company or the environmental benefits of a product or service. Source: www.sinsofgreenwashing.org
Truth? Lighter, cleaner and more energy efficient than precast…
The process An credible LCA requires: Good data: oManufacturer data (9 precasters); oPCA reports with LCI data on cement and concrete; and oU.S. LCI database (NREL) A good process: oISO 14040 oISO 14044 Transparency: oExternal review team; and oExperienced consultant.
Credible partner LCA consultant –RFP creation –Lit review –Interview moderator Interviewed 3 –Athena/Morrison Hershfield –PE Americas/Five Winds –CIRAIG External review team –Professor, Carnegie Mellon –Berkeley Labs –British Precast Association
Why an LCA? To benchmark industry and back claims RequestsOwners Requirements Congressional Caucus Coalition (hpbccc.org)
Comparative analysis 3 partners Phase 1: Comparative analysis Per ISO, specific requirements for disclosed, comparative assertion LCAs. Data for all products must be treated equally and be of similar quality.

New Eco-shape bottle uses 30% less plastic. The new bottle weighs 12.5 grams which is 15% less. Nestle estimates it will save 65 million lbs of plastic with Eco-shape. Cap was blue, which wasnt recyclable. Example: manufacturer changes
What do we do with an LCA? Improve our processes Improve our products Improve structures
Next steps Phase 2-Building use Transportation products
