The project building proposes to earn credit toward EQ 3.4-3.6 by purchasing high density plastic trash can liners that contain less than 10% recycled content but also have a thickness of no more than 0.70 mils. This proposed exclusion to the EPA\'s procurement guidelines for plastic trash can liners is based on the principal of source reduction and the desire to minimize the project building\'s purchase of virgin plastic. The proposed guideline of 0.70 mils is based on the California Recycled Content Trash Bag Program outlined in the California Code of Regulations Title 14, Chapter 4, Article 5. While the EPA\'s procurement guidelines call for plastic trash can liners that contain a minimum 10% recycled content, it is impractical for liner manufacturers to produce a functional plastic trash liner which contains at least 10% recycled content but is also 0.77 mils thick or less. Major manufacturer\'s Heritage Bag, Pitt Plastics and Berry Plastics each produce bags with 10% recycled content, but the minimum thickness of these bags is 1.0 mil. These manufacturers have informed the project team that it is impractical to manufacture a thinner bag with 10% recycled content without compromising the tensile strength of the bag and consequently requiring "double bagging" in the field. From a source reduction standpoint, a 0.70 mil virgin bag contains 24% less virgin plastic than a 1.0 mil bag that contains 10% recycled content. The California Recycled Content Trash Bag Program requires trash liners to contain at least 10% recycled content, but the Board also provides an exclusion for liners with a thickness of 0.70 mils or below. Please clarify whether the US Green Building Council would allow the project building to earn credit toward EQ 3.4-3.6 for the purchase of high density plastic trash can liners that contain less than 10% recycled content but also have a thickness of no more than 0.70 mils.
