Steel reduces waste and features a material recovery rate greater than 98%! Structural steel features an incredibly sustainable manufacturing process. Consider these facts:
The structural steel making process boasts a 95% water recycling rate with no external discharges, resulting in a net consumption of only 70 gallons per ton.
Steel is the most recycled material in the world. Domestic mills recycle more than 70 million tons of scrap each year and structural steel has a 93% recycled content!
Steel production productivity levels are up by a factor of 24 and labor hours have been reduced from 12 to just 0.5 per ton.
Steel’s carbon footprint is down 37%, energy use has decreased 32%, and greenhouse gas emissions have dropped by 45%.
Steel is the most resilient material, designed to last, whether it’s exposed to fire, blast, or the ravages of time. And when a steel building reaches the end of
its life, the steel is recycled and retains all of its fantastic physical characteristics. Today’s beams and columns are nearly 40% stronger and offer greater constructability benefits!
The American Institute of Steel Construction provides environmental product declarations (EPDs) for fabricated hot-rolled structural sections, fabricated steel plate and fabricated hollow structural sections. These EPDs cover the product life cycle from cradle to fabricator gate and are available at www.aisc.org/epd.
