Environment - Production and Processing
Reducing Our Impact
We strive to reduce our environmental impact. Our facilities are or are becoming
state-of-the-art with the latest pollution control technology. Our production of
stainless steel through electric arc furnaces is the most energy efficient and
eco-friendly form of steel production available, limiting greenhouse gas
emissions. We make constant improvements to our processes to become even more
environmentally friendly.
We are always looking for ways to become more efficient. A recent example is our
new state-of-the-art titanium sponge facility being built in Rowley, Utah. We built
the facility next to an existing producer of magnesium. This saves direct
transportation costs and reduces our need to remelt the magnesium before processing,
thereby reducing our carbon emissions and energy usage. We are also able to easily
ship a magnesium byproduct back to the producer for reprocessing, further improving
our production efficiency.
In the construction of the new advanced specialty metal hot rolling
and processing facility in Brackenridge, PA, we are reusing and
recycling the structural steel and masonry, concrete and
bricks from old buildings that were on the site and razed during site
preparation. The new facility will be equipped with advanced technology
pollution controls and energy-efficient technology.
Monitoring
We consider environmental compliance to be an integral part of our operations.
We have a comprehensive environmental management and reporting program, and require
compliance with all federal, state, regional and local environmental laws and
regulations.
Each of our operating companies has an environmental management system. Through
these systems we monitor our environmental performance, particularly in the
face of changing business operations. We strive to be in
compliance but any noncompliance is promptly corrected and root cause analysis
is employed to prevent any recurrence.
Recycling
We always look for opportunities to recycle and reuse materials. In fact one
of the hallmarks of our Allegheny Technologies Incorporated Business System
(ATIBS) is the elimination of waste in all phases of our manufacturing
processes. Besides reducing our environmental impact, recycling improves our
bottom line by cutting our operating costs.
Many of the products that we manufacture, such as stainless steel and
nickel-based alloys, begin as used materials (i.e., scrap metal), and the
finished products are themselves recyclable. Approximately 75% or more of the
raw materials that ATI Allegheny Ludlum and ATI Allvac use to manufacture specialty
metals start from scrap material, which is either purchased or
internally-generated by our own manufacturing processes. Once those specialty
metals reach the end of their life span, as scrap metal they can be recycled as
raw material for new specialty metals. Most of our other operating companies
also use scrap metal as starting materials, although on a smaller scale. See
this article for a discussion of recycling
at ATI Allegheny Ludlum.
Our commitment to recycling and reusing materials is also evident in the
following examples:
-
Some of our slag materials remaining from melting specialty metals are
processed to remove valuable metals, such as chromium and nickel, which is then
reused in our melting processes.
-
The remaining slag components are usable as construction material, such as for
road building.
-
Substantial recycling and regeneration occurs at our facilities in our acid
pickling operations, such as the recirculation and regeneration of nitric and
hydrofluoric acids.
-
ATI Allvac recirculates processing water for minimal water consumption, instead
of drawing new water from rivers and streams.
-
Waste stainless steel liners from ATI Wah Chang are recycled by ATI Allegheny Ludlum and used as raw material input.
-
We have implemented various environmentally friendly practices throughout the company,
such as recycling office paper, aluminum cans, plastic bottles and waste wood products,
replacing lights with compact fluorescent light bulbs, and keeping lights off when a
room is not in use. In fact, over the past two years,
our office paper recycling efforts have saved over 200 trees.
-
Where possible, we promote scrap buy-back programs with our customers to
encourage recycling.
