MINIMIZING OUR IMPACT AND PROTECTING NATURAL RESOURCES.
Steel is the most recycled material in the world — and few companies can claim to recycle as much metal as CMC. After being melted in our high-efficiency electric furnaces, recycled scrap metal is transformed into finished products in our rolling mills or fabricated to customer specifications for use in projects around the globe. All told, this vertically integrated manufacturing process saves more than 18 billion pounds of scrap metal from being landfilled annually — enough to fill an Olympic-sized swimming pool 11 times every day for an entire year!
We’re also finding ways to recycle steel more efficiently and cleanly. Our innovative electric arc steelmaking technology consumes fewer natural resources and generates less emissions compared to the traditional blast furnaces. For every ton of steel that’s recycled, we conserve the use of 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone. What’s more, by using a scrap-based EAF steel making process, our CO2 emissions are 8 times less than the global steel making average and we are able to help preserve our natural resources.
RECYCLED STEEL IS USED TO MAKE NEW PRODUCTS
LESS CO2 IS EMITTED FROM CMC'S EAF TECHNOLOGY THAN OTHER TYPES OF MILLS
LESS ENERGY USAGE THAN INDUSTRY AVERAGE
As part of our overall effort to promote environmental responsibility, CMC focuses on these key areas:
- Encouraging recycling, recovery and reuse when possible in all of our processes
- Improving our energy efficiency
- Increasing our water reuse and recycling rate
- Encouraging greater environmental awareness and responsibility among our employees
- Reducing our overall carbon footprint
To further reduce energy consumption, CMC has partnered with the U.S. Department of Energy to take part in the “Better Buildings, Better Plants” Program. The goal of this initiative is to drive significant improvements in energy efficiency across all U.S. industries. Through our participation, CMC is committed to improving efficiency in our existing operations and making energy conservation a primary factor in purchasing or upgrading equipment at all our facilities.
As part of Commercial Metals Company’s Guiding Principles, CMC takes seriously the responsibility that comes with being a good corporate citizen. We’re dedicated to making a positive impact in our local communities where we live and work. And at the core of what we do to better our communities, we encourage recycling, recovery and reuse of residual materials.
CMC is committed to conducting all aspects of our business to ensure we are in compliance with state and federal environmental rules, including all applicable laws, regulations, permits and authorizations and internal requirements governing our operations.
We endeavor to communicate effectively with our employees, neighbors and stakeholders, and continually improve our environmental compliance program through regular evaluations and technological advances. And by identifying areas where we can do better than compliance, we are preventing pollution, avoiding and minimizing environmental impacts, and using advances in technology to operate our facilities in a cleaner, more sustainable way.
CMC SUPPORTS THE LEED® INITIATIVE
CMC is committed to sustainability from recycling to production to fabrication of steel products. We are dedicated to being transparent about reporting the environmental impact we have on the Earth.
We support the efforts of the U.S. Green Building Council and are active in the Leadership in Energy and Environmental Design (LEED®) initiative. LEED® is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across a number of metrics.
All of CMC’s steel mills utilize state-of-the-art Electric Arc Furnace technology to make steel. This technology uses pre- and post-consumer recycled scrap as the primary raw material for the steelmaking process and averages 98.0% recycled content. With a significantly high percentage of recycled materials, all of CMC’s products play a major role in “green construction” and are a positive contributor to the LEED® rating system.
CMC can supply fabricated rebar that can contribute a full credit under LEED® v4 or LEED® v3 (2009), since we have a national fabrication footprint and manufacturer-specific USGBC EPDs.
On October 31, 2016, USGBC officially transitioned to LEED® v4. The sunset for LEED v3 is currently set for was June 31, 2021. The below links will direct you to CMC’s LEED® data for the current LEED® v4 as well as LEED® v3 for those projects that are qualifying under the legacy rating system. CMC is helping to “LEED®” the way to sustainable steelmaking.
This analysis was conducted according to the North American Product Category Rule (PCR) created by SCS Global Services for Designated Steel Construction Products (SCS 2015) and reviewed and certified by ASTM as conforming to the requirements of ISO 21930 and ISO 14025.
To meet LEED® v4 requirements, these Environmental Product Declarations (EPDs) have been developed for the following steel products manufactured at CMC steel mills.
