ttc a -1 ri er o ei iins One of the key barriers to professional discussion and dialogue about the nature of the problem and alternative solutions to increasing recovery from municipal residential recycling programs is a lack of standardized definitions. The following set of terms is proposed to the City and Ramsey County as a basis for such discussion. "Non-Targeted Materials" -Materials that are defined by the municipality as not acceptable but yet are still included by residents in their curbside bins. Thus, this is acity-specific definition as determined by contract and/or public education tools communicating acceptable recyclables and non-acceptable materials. For the City's definition, see the Roseville web page http://www.ci.roseville.mn.us/info/recycle/sort.htm under "Don't include these items" The Project Team also uses the term "Rejects as collected" for purposes of the Roseville composition analysis (R.W. Beck, City of Roseville Recyclable Materials Sorts -Draft Data Analysis: Attachment A -Composition Analysis Categories, March 23, 2005). The following sub categories were used as "Non-Targeted Materials" as collected and sorted for the City's composition analysis: Beer, Pop & Water Boxes Other Paper Trash Plastic Bags and Other Film Plastic ® Other Trash The City and R.W. Beck also used the term "contaminants" in their recent draft reports to refer to non-targeted materials. "Processing Residuals" -Materials that are disposed as mixed solid waste as an unwanted by-product after processing of recyclables at materials recovery facilities (MBEs). For example, paper trash items that are not acceptable by the MRF operator or contaminated to the point of rendering the items as not marketable. "Contaminants in marketed product" - Outthrows and prohibitives as defined for specific commodities and grades by each end market (i.e., mills or other manufacturing plants that utilized processed recyclable materials). For example, glass is a prohibited contaminant in most end market specifications for newspaper bales from recovered paper suppliers. The Institute for Scrap Recycling Industries (ISRI) defines a set of standardized specifications that many buyers and sellers in the metals, glass, paper, and plastics recycling industries use as a basis for more customized B 1 cos
