SCI launches new protocol for reusing steel
In an effort to help the steel construction industry reduce greenhouse emissions, the Steel Construction Institute (SCI) has launched a new protocol for reusing steel.
According to the SCI, a growing realisation of the urgent need to reduce or even eliminate, greenhouse gas emissions is focussing attention on what we build and what construction materials we use.
Although the focus has been on reducing operational impacts from heating, cooling and lighting, there is growing pressure to think more about the impacts of construction materials, so-called embodied impacts.
The steel manufacturing industry has made good progress in reducing its emissions, but efficiency is approaching the theoretical limit using existing technologies. Although some steelmakers are exploring exciting, new step-change technologies, easier, lower cost reductions can be made from demand-side measures particularly from using steel products more efficiently; this includes reusing as opposed to the current practice of recycling (by re-melting) structural steel.
Building on recent national and international projects on structural steel reuse, SCI said it has developed a protocol to help facilitate the reuse of structural steel sections reclaimed from existing building structures.
The protocol proposes a system of investigation and testing to establish material characteristics, with advice for designers completing member verifications. The protocol places important responsibilities on the holder of salvaged steelwork including identification, assessment, control procedures and declarations of conformity.
The protocol is founded on the principle that given appropriate determination of material characteristics and tolerances, (re)fabricated salvaged steelwork may be fabricated and CE marked in accordance with BS EN 1090.
