Attachment A <br />Primer an De#initions <br />One of the key barriers to professional discussion and dialogue about the nature of tl�e <br />problem and alternative solutions to increasing zecovery from municipal residential <br />recycling programs is a lack of standardized definitions. The following set of terms is <br />proposed to the Ciiy and Ramsey County as a basis for such discussion. <br />"Non-Tar�eted Materials" - Materials that are defined by the municipality as <br />not acceptable but yet are still included by residents in their curbside bins. <br />Thus, this is a ciry-specific definition as determined by cont�ract and/or public <br />education tools comxnunicating acceptable recyclables and non-acceptable <br />materials. For the City's defiruition, see the Roseville web page <br />htt ://www.ci.roseville.mn.us/info/rec cle/sort.htm under "Don't include the.se <br />iteins" <br />The Project Team also uses the term "Rejects as collected" for purposes of the <br />Roseville composition analysis {R.W. Beck, Ci o Roseville Rec clable <br />Materials Sorts — Dra t Data Analysis: Attachment A- Compositian Analvsis <br />Categories, March 23, 2005). The following sub categories were used as <br />"Non-Targeted Materials" as collected and sorted for the City's composition <br />analysis: <br />• Beer, Pop & Water Boxes <br />• Other Paper Trash <br />• Plastic Bags and Other Film Plastic <br />• Other Trash <br />The City and R.W. Beck also used the term "contaminants" in their recent draft <br />reparts to refer to non-ta.rgeted materiaIs. <br />"Processin� Residuals" - Materials that are disposed as mixed solid waste as <br />an unwanted by-product after processing of recyclables at materials recovery <br />facilities (MRFs}. For exarnple, paper trash items that are not acceptable by <br />the MRF operator or contaminated to the point of rendering the items as not <br />marketable. <br />"Contaminants in nuarketed product" - Outthrows and prohibitives as <br />defined for spec�fic commodities and grades by each end xna.rket (i.e., znills or <br />other manufacturing plants that utilized processed recyclable materials). For <br />example, glass is a prohibited conia�ninant in most end tnarket specif.cations <br />for newspaper bales from recovezed paper suppliers. <br />The Institute for Scrap Recycling Industries (ISRI) defines a set of <br />standardized specifications that many buyers and sellers in the metals, glass, <br />7noros DR,qF'F <br />
