Recycle passes ESCR test for pipe.Post-consumer recycled HDPE has been "demonstrated to be suitable for use in production of corrugated cor·ru·gate v. cor·ru·gat·ed, cor·ru·gat·ing, cor·ru·gates v.tr. To shape into folds or parallel and alternating ridges and grooves. v.intr. pipe for culverts and storm drains," according to test results just reported to the U.S. Environmental Protection Agency Environmental Protection Agency (EPA), independent agency of the U.S. government, with headquarters in Washington, D.C. It was established in 1970 to reduce and control air and water pollution, noise pollution, and radiation and to ensure the safe handling and by the University of Toledo National recognition In its 125-year history UT has garnered several national accolades. The University’s programs, faculty and facilities have been highlighted in the media, including (Ohio) Polymer Institute. These results are significant because corrugated drainage pipe consumes a major portion of all PCR PCR polymerase chain reaction. PCR abbr. polymerase chain reaction Polymerase chain reaction (PCR) HDPE, by some estimates (see Industry Newsfocus). Double-walled, 24-in.-diam. pipe made with a mix of virgin resin and 25%, 50% or 75% post-consumer detergent-bottle regrind was tested over months for environmental stress-crack resistance. In ESCR tests using modified ASTM D1693 procedures, no failures were found at even 75% PCR content. All three recycle blends, and 100% virgin resin, were also tested by a more stringent ASTM test for ESCR, which none passed--not even the virgin sample. Testing was funded by the EPA EPA eicosapentaenoic acid. EPA abbr. eicosapentaenoic acid EPA, n.pr See acid, eicosapentaenoic. EPA, n. and the Ohio Departments of Transportation and Natural Resources. The purpose of the research was to show that PCR-content resins perform no worse than 100% virgin resins, according to John Hurd, Ohio DOT assistant hydraulic engineer. |
