Environmental Benefits of Repurposed Tubular Steel Sourced from Pipe Mill Secondary and Oil Field Surplus-Video

Video Transcription

Video Summary

The presentation describes a life-cycle assessment of repurposed secondary-market steel pipe used in construction foundations. Because verified emissions data for reused pipe was unavailable, the company worked with environmental consultants to assess 2022 operations across five life-cycle stages, from incoming materials and transport through installation. The study analyzed roughly 27,000 tons of steel and established that the pipe carries 13.2% of the carbon burden associated with new mill steel.<br /><br />For one metric ton of pipe, emissions were 455 kg CO₂-equivalent from production through the distribution yard, and 694 kg when delivery and installation were included. Compared with new mill steel, repurposed pipe reduced emissions by 77–83% before installation and 68–75% when installed. A foundation project using about 1,100 tons of pipe avoided an estimated 2,132 tons of CO₂ emissions.<br /><br />The verified results are available in an environmental product declaration and have been incorporated into the DFI carbon calculator, helping construction teams assess and reduce project emissions.
