per ton of metal. Mainly due to the fact that the energy
of hydroelectric power plants (HPPs) is used in the
production of aluminum. The global average is 12
tons of СО
2
. In China, the largest producer of
aluminum, where coal plants form the basis of
energy, the carbon footprint reaches up to 18 tons per
ton of metal (Strohmeier, 2007; Tzafrir, 2005).
RUSAL has registered its own brand of "low-
carbon" aluminum Allow, including for its more
successful promotion with the "green brand" on the
world market. RUSAL plans to develop its
advantages, has begun a large-scale modernization of
its four largest plants in Krasnoyarsk, Bratsk,
Shelekhov (near Irkutsk) and Novokuznetsk. This
project will require 380 billion rubles and is designed
for 2022-2027. RUSAL expects that by updating
production and switching from the traditional
electrolysis technology used worldwide to the
prebaked anode electrolysis technology, it will make
its aluminum production even more productive,
environmentally friendly and economical.
Along with aluminum producers (RUSAL, etc.),
manufacturers of metal products made of aluminum
alloys (tapes, sheets, profiles, pipes, rods, stampings)
adopt and implement their strategies and programs for
the transition to "green technologies" and "green
metal products" together with increased productivity.
So, for example, Arconic Corporation (Arconic),
which includes the company Arconic SMZ JSC
(hereinafter SMZ - Samara Metallurgical Plant), due
to the "greening" of their technologies, significantly
improved environmental indicators for 2020 -
according to the corporation, greenhouse gas
emissions were reduced at plants around the world (-
14%), consumption energy (-12%) and water (-8%);
SMZ reduced the consumption of electricity (-6%),
gas (-7%) and water (-13%) (Sarukhanyan, 2016)
(Sarukhanyan, 2016;GOST R ISO 14001-2016).
In 2020, SMZ once again confirmed compliance
with the requirements of the international
environmental standard ISO 14001, and also received
professional recognition from the international
organization ASI (Aluminum Stewardship Initiative),
which develops and promotes standards for
responsible management of aluminum production
and marketing. In the annual regional competition of
the Samara region "Eco-leader – 2020", SMZ took
first place in the nomination "Industrial Giant".
Constant investments help the plant to comply with
advanced technologies and environmental standards:
since 2005, USD 0.5 billion have been allocated for
the modernization of the SMZ, including for the
improvement of environmental protection and
industrial safety systems – more than USD 40 million.
A multi-year program for the conservation of the
biodiversity of the Samara region, which is supported
by the Arconic Foundation, contributes to the
protection of the ecological well-being of the Samara
region. Over 5 years, the Fund has allocated USD 235
thousand for the implementation of environmental
projects in the Samarskaya Luka National Park and
the Zhiguli State Reserve (Amrutha, 2020; Zakharov,
2019).
Arconic and SMZ aluminum metal products can
be attributed to the leaders in environmental
friendliness – to "green semi-finished products".
Their use in subsequent technological conversion
industries (packaging, mechanical engineering,
construction, etc.), producing the final "green
products", carries not only an improvement in the
technical characteristics of products and economic
benefits, but also positive environmental effects.
3 RESEARCH RESULTS
An example of a "green metal product" of SMZ is an
aluminum tape for beverage cans. Aluminum can is a
leader in recycling and environmental friendliness.
The figure 2 shows the scheme of production and
recycling of aluminum, tin tape and cans. From 4 tons
of bauxite, 2 tons of alumina are obtained, of which 1
ton of aluminum. Further along the production cycle
and recycling, all waste (there is a permanent program
to reduce them) and recycled cans are fully involved
in production. Treatment and recycling of one
aluminum can (0.5 liters – 14 grams) instead of
producing an appropriate amount of primary
aluminum by electrolysis, prevents the release of 100
grams of
CO2
. In Russia, there are factories for the
production of aluminum cans with a total output of
several billion pieces per year. Aluminum alloys, due
to their advantages, are increasingly used in transport
engineering. Arconic Corporation is actively working
in this direction. Along with the supply of metal
products for the aircraft industry, Arconic, together
with manufacturers of ground transport equipment,
participates in the creation of new types and models
of machines using aluminum parts and structures. The
corporation's enterprises master and supply the new
types and sizes of metal products necessary for this.
For example, Ford uses an all-aluminum body made
of Arconic sheets and profiles in the manufacture of
the F-150 SUV pickup truck. SMZ initiates and
participates in a number of projects for the use of its
products in special road and rail transport. Examples
of such machines are railway hoppers – for the
transportation of bulk products, tankers for the
