Following approval by the Nonferrous Division of the Washington-based Institute of Scrap Recycling Industries (ISRI), the full ISRI board of directors will vote whether to approve the changes when it meets in early February in Coral Gables, Florida.
For the grade known as “saves,” which consists of discarded die-cast zinc scrap, the phrase “material can include zinc dies/molds for shoes or other industrial purposes” has been proposed as an addition to the existing specification.
Another grade known as “scroll,” which consists of unsorted die-cast zinc material, may have its specification changed to include additional metals in a list of other nonferrous metals that may be present in a shipment.
The current scroll specification reads in part, “Other nonferrous metals such as aluminum, stainless steel, etc., to be about 40 percent.” The proposed revision would add the words “brass/copper/copper alloys” after stainless steel.
According to ISRI, its board “may choose to adopt, amend or reject” the recommendations of its Nonferrous Division or to table the changes pending further review.
