BSW ENVIRONMENTAL DECLARATION 2012

1. Preface

Active protection of the environment is a fundamental challenge and one of the

most important tasks for safeguarding our future standard of living. This means

that from the start in the developmental stage of a product, the manufacturer

must consider how it can be recycled or disposed of without harming the

environment.

Yearly, world crude steel production amount to more than 1 billion tons (approx.

50 million in Germany), 40 % of this is based on scrap. No other material has a

similarly proven and efficient recycling system as steel. Due to its complete

recyclability, steel renders closed material circuits possible.

BSW's objective in publishing this document is to provide information about its

environmental activities at its Kehl location and to enter into an open dialogue.

This review furnishes data for an assessment of the environmental issues and

describes the company's environmental and energy policy, its targets, and the

environmental and energy management system already in place.

Kehl, 04.04.2012


2. Environmental and Energy policy of Badische Stahlwerke

2.1 Environmental policy

Steel is one of the most important materials in the world and with its various

fields of application and application possibilities the development of mankind

cannot be imagined without it. Under ecological aspects, steel is an excellent

material as it may be used mainly infinitely and without any loss of quality. In the

course of the last few decades steel production in the electric arc furnace has

developed into an efficient process. Badische Stahlwerke GmbH (BSW) has

managed to develop their environmental activities in a sustainable way and will

continue on this way in the future as far as possible with regard to technical and

environmental aspects. The environmental policy is reflected in the environmental

guidelines.

The Environmental guidelines are: Management system, program and objectives Our environmental management system, the environmental program and the

objectives defined in this context aim at the safeguarding and sustainable

improvement of the environmental protection. Compliance with legal regulations

is our minimum standard and is compulsory for us.

Environmentally friendly production We make sure that our products are manufactured with minimum input of

resources and environmental impact. It is our aim to keep the environmental

influences related to steel production as low as possible and to improve the

associated processes continuously.

Appearance of the plant We attach great importance to cleanliness and order in our plants, which

contributes to the positive appearance of our facility.

Motivation and qualification of staff The training and qualification of our staff as well as our information policy aim at

enhancing an environmentally conscious behaviour. The ideas management

existing at BSW further serves for an active improvement and motivation in the

field of environmental protection. The employees are obligated to keep to the

legal requirements and the environmental regulations established by BSW.

4 | 5

Public authorities and the public We participate in various regional task forces and thus enter into an open

dialogue with the public. We attach great importance to a good cooperation

with residents, associations and public authorities and approach environmental

topics conjointly.

2.2 Energy policy

The introduction of the Renewable Energy Law (EEG) in 2009 provided for energy

intensive companies like BSW the opportunity to make use of compensation

schemes in order to minimize costs for the promotion of regenerative energies. In

order to fulfil these requirements and to counteract the increasing energy prices,

an energy management system acc. to DIN EN 16001 was integrated in the

existing environmental management system (DIN EN ISO 14001 and EMAS III).

The energy management comprises all measures to guarantee minimum energy

consumption. All relevant energy fluxes are systematically recorded in order to

assess and effect respective investments for improving energy efficiency. The

energy management is meant to exert influence on the design of the information

and organisation structure, the energy policy of the company, planning,

operation of the equipment, control and adjustments and the internal audits.

The following objectives shall be achieved in the long term:

Cost reduction

Elimination of weak points and use of potentials for savings

Reduction of greenhouse gases

Efficiency of resources in the field of energy carriers

Positive external presentation of the energy and climate policy

Compliance with legal demands

Utilization of legal facilitations


3. The Enterprise and history

Location Badische Stahlwerke (BSW) currently produce approximately 2.1 m tons of rolled

products with a staff of approximately 800 employees and thus belong to the

productivity leaders worldwide. BSW is the only steel plant in Baden-

Württemberg. The location in the Rhine harbour of Kehl, on a small headland

with a surface of ca. 300.000 m2 between one of the three harbour basins and

the river Kinzig is still one of the decisive factors for the success of the company.

The city of Kehl and the French metropolis Strasbourg are in close vicinity of

BSW. The community of Auenheim is their direct neighbour in Eastern direction.

4. From scrap to steel the electric steel production as a recycling process

Today more than 1 billion tons of steel are produced worldwide, and more than

400 million tons are based on scrap. In this way, the natural resource as well as

the related auxiliaries and energies are saved which would have been required for

production in a blast furnace or a converter. At the same time impacts to the

environment are reduced.

1 ton of steel

made from scrap

reduces water consumption by approx. 40 %

reduces air pollution by approx. 85 %

reduces energy consumption by approx. 75%

Electric steel mills play an important role in industrial society's materials cycle:

They produce steel from scrap metal. Charging materials for electric steel mills

include scrap from vehicles (shredded scrap), demolition scrap, and new scrap

like sheets and turnings.

Start of steel production at the scrap yard Over 70 percent of the scrap used in steel production is delivered directly by

Rhine barges, the remainder coming by rail. The quality of the scrap is

continuously monitored. Overhead cranes unload the approximately 2.5 million

tons of scrap delivered each year. The storage capacity of approx. 50,000 tons is

sufficient for around a week’s production. The so-called scrap buckets which are

loaded on scrap cars are filled with scrap by means of the gantry cranes and are

then transferred to the steel plant through the two furnace bay gateways.

Electric arc furnaces The steel plant is comprised of two AC-arc furnaces (EAFs) that melt the scrap

with an arc, boosted by gas-oxygen burners. Up to 110 tons of scrap are melted

per heat and the tapping weight (molten steel) is up to 100 tons. The furnaces

are tapped after an average meltdown time of 40 minutes. Tapping temperature

averages 1,600 °C.

Dust Collecting Plant The continuous development of energy-conserving technologies is essential for

economic survival for a steel producer based in Germany, because energy costs

make up approximately 30 % of controllable revenue. Environmental benefits –

the reduction of atmospheric, water, and noise emissions – are usually “mere”

side-effects. We are nonetheless proud of the environmental protection

technology which we market worldwide with our affiliated company BSE

(Badische Stahl Engineering GmbH).


Central alloying plant When steel is produced from scrap, fluxes and alloys have to be added to obtain

the required grades.

At BSW the fluxes and alloys are delivered to the alloy storing silos unit by truck

where they are unloaded through a funnel and transported to a hopper plant on

a conveyor system. The materials needed for production are collected from the

hopper with the help of weighing equipment and transported to the furnaces via

conveyor belts and chutes.

An automated alloy feeding system was installed in 1996 to reduce dust

emissions as well as on-site transportation of fluxes and alloys. Dust generated in

the vicinity of the additive and alloy truck unloading station is directly extracted

through a de-dusting system (jet filter plant).

Explanations ng: nanogram: 1 ng = 10-9 g corresponds to one billionth of a gram TE: Toxicity equivalents: all dioxins and furans are valued with factors ranging from 0.001 to 1, depending on their toxicity, and are represented as a sum Nm3: Standard cubic meter: to be able to compare gas volumes they are represented in a standard state (0 °C and 1.013 bar)

The direct extraction system including dust collecting plant is a typical example:

The generated off-gases are sucked off directly in the furnace bay as well as by a

meltshop ventilation system with a capacity of approx. 1.8 million Nm3/h and

cleaned in the de-dusting systems with a filter area of 38,000 m2. The average

total dust value in the clean gas is approx. 1 mg/Nm3. Dioxines and Furanes are

reduced before the filter in a post combustion chamber with subsequent

quenching system to a value below 0.1 ng TE/Nm3.

Ladle furnaces While the electric arc furnaces melt the scrap as quickly as possible, the alloys are

added in the ladle furnace based on the chemical analysis of the steel and the

temperature is adjusted to the correct level. The steel stays in the ladle furnace

for approximately 20 to 30 minutes, after which the ladle is traversed by crane to

the continuous casters.

Continuous casting plant At the continuous casting plant, the molten steel is poured from the ladle into a

tundish (a tub-like vessel) with five (casting plant 1) or 6 (casting plant 2) nozzles,

through which it runs into a 1,000 mm long copper mold. A lifting table

oscillates the molds while the molten steel is water-cooled until billets are

formed. Casting speed depends on the capacity of the cooling system. The billets

are then transported to the rolling mills by means of the crane units. Installations at the rolling mill Pusher type furnaces The billets are reheated in pusher-type furnaces fuelled with natural/liquid gas

which are located upstream of the two rolling mills. This process is computer

controlled. Before the billets produced by the two continuous casters can be

heated to rolling temperature in the pusher furnace, a chemical analysis is

performed on them. The results determine how the billets are to be used. The

evaluation process is time-consuming, due to the large volume of data analyzed

and other factors that have to be taken into account. A program has been

developed to help staff decide how to process each heat. This saves time and

energy because it enables billets to be charged into the pusher furnace while

they are still hot.

Bar mill (rolling mill I) In the bar mill the billets are rolled into deformed rebar with a diameter of 10 -

40 mm and a length of 6 - 20 m. The bars are strapped into bundles weighing

around 2.5 tons ready for shipping. The 10 - 20 mm dimensions are produced by

slit rolling, in which a billet is divided into two, three, or four final cross-sections

simultaneously. An Average of 100 tons of finished steel products are rolled per

hour.

Wire rod mill (rolling mill II) The two-strand wire rod mill produces plain wire rod (5.5 mm up to 13.5 mm

diameter) as well as ribbed reinforcing bars. (6 up to 14 mm diameter).

The wire rod mill consists of a roughing, intermediate and finishing train. After

the finishing train the wire is cooled down in the primary water cooling line and


Reference year 2000 (see 5.3 Key indicators) * In 2010, short-time work for a period of 6 weeks due to the economic situation

disposed on a roller table which at the same fulfils the function of a secondary air

cooling line. The end of the roller table already belongs to the wire adjustment.

The wire drops through an opening and will be gathered as a coil with a total

weight of 1.8 t. The wire is then forwarded with a hook conveyer to the coil

tying machine.

At the moment the converting speed is up to 95 m/s and shall be increased to

more than 100 m/s. An average of 180 t finished steel products is produced per

hour.

Recycling at steel and rolling mills

Besides the finished product "steel" by-products and wastes are generated

during the steel production process which in terms of the closed loop recycling

management can be returned again to the production process or utilized as

environmentally friendly resources, respectively.

Internal scrap

Refractory breakout material The steel vessels of electric arc furnaces, ladles and tundishes are lined with

refractory materials to protect them from the molten steel.

The refractory material has to be renewed at regular intervals. The breakout

material is processed in a screening plant and some of it is reused by BSW. The

remaining material is sold to the producers of refractories who process it into

refractories for use in steel mills, completing the recycling process.


Internal scrap Internal scrap consists of reinforcing steel only. It is generated in the continuous

casters as shrink heads, ladle and tundish skulls, and in the rolling mills as

shearing waste, cobbles and scrap bundles. Before being charged into the

furnace some of the internal scrap has to be cut into furnace sizes in the torch

cutting area.

Electric arc furnace slag (EAF slag) 120 - 150 kg of furnace slag, a fused rock material very similar to natural rock, is

generated with each ton of steel produced by BSW. The main components of this

slag are natural compounds like iron (as oxide), unhydrated lime, sand and oxides

of magnesium, manganese and aluminum.

Mechanical processing into high-standard road construction and hydraulic

engineering materials takes place in an external slag treatment plant. The final

products, similar to processed gravel, with different granulations which are

monitored by an independent scientific institute. Only approved and quality-

tested material is delivered to construction sites.

Depending on its grain size the processed slag can be used for various purposes:

Road construction

Hydraulic engineering

Construction of parking lots

Rail construction

Electric arc furnace slag serves as an alternative building material to gravel, thus

conserving natural resources.

Casting bay slag The casting bay slag is also processed in an external plant. It is mainly used for

dirt road construction e.g. for forest tracks and for piling up of noise protection

walls.

14 | 15

Meltshop dust In all steelmaking processes, wastes in the form of dust are generated in the de-

dusting plants.

The dust is extracted by direct suction and bay suction systems and conducted to

the filter baghouse where the dust-loaded crude gas is cleaned via filter bags.

The dust load in the crude gas exceeds 4 g/Nm3. The clean gas side of the

baghouse shows a residue of approx. 1 mg/Nm3 on average per year, which is

equivalent to a separation degree of over 99.9 %.

The dust contains elements that evaporate at high temperatures during melting

and condense again when the gases cool. These include zinc and lead as well as

minute quantities of dioxins and furans. The dust is supplied to authorized plants

which recover elements such as zinc.

Principal components of dust:

Iron oxide (Fe2O3) approx. 30 %

Zinc (Zn) approx. 25 %

Calcium oxide (CaO) approx. 5 %

Anorganic chloride compounds (Cl) approx. 2 %

Lead (Pb) approx. 2 %

Mill and continuous casting scale Scale consists mainly of iron oxide and forms on the hot steel surface. It is

severed from the steel by mechanical stress and contact with cooling water. Scale

particles fall into the cooling water and are deposited in worm classifiers, laminar

separators, hydro cyclones, sedimentation tanks and sand filters. The scale

generated in the continuous casters and the rolling mills is processed to

briquettes in external plants and used in blast furnaces for pig iron production.

Here also, the material flow loop is closed. For protection of resources the scale is

used as substitute material for iron ore in the cement industry.


5. Environmental and Energy aspects and key indicators

5.1 Environmental aspects

According to EMAS all activities, products and services must be audited from the

point of view of their effects on the environment. Based on the results of the

audit, it must be decided which effects have the greatest impact on the

environment and how they can be controlled or improved.

Direct environmental aspects are related to activities controlled by the

company. The aspects considered to be "essential" are as follows:

1. Generation of waste (industrial waste and hazardous waste, see Chapter

5.3.4) 2. Waste water (sewage disposal and generation, see Chapter 5.3.3) 3. Climate relevant gases (CO2 generation, see Chapter 5.3.5) 4. Energy (see energy aspects, Chapter 5.3.1) 5. Noise (Generation by equipment, vehicles, monitoring via noise

measurement, see Chapter 5.3.5) 6. Air emissions (dust, NOX, CO, see Chapter 5.3.5) 7. Water (well water and public water consumption, see Chapter 5.3.3)

Indirect environmental aspects can comprise activities, products and services

which the company may possibly not be able to control completely. Indirect

environmental aspects are:

Hazardous materials transportation (hazardous waste disposal and supplies) Hazardous materials transportations are transports of waste material like e.g.

waste oil, paint and acids, but it can also mean supplies of technical gases and

other operating materials. Collection and deliveries are controlled by the risk

prevention officer. We only employ special waste management companies or

companies with the respective qualification for hazardous material

transportation. Suppliers and contractors Suppliers and service providers are informed about the energy and environmental

management system of BSW. The purchasing guidelines include environmentally

and energy relevant topics. Environmental protection is a key criterion for the

evaluation of suppliers. Contractors working on the company site apply the same

environmental standards as BSW.

16 | 17

Recyclability of products (steel products) and by products (slag, refractories) In terms of the closed loop recycling management the steel products

manufactured by BSW can be reused by 100 % as starting material for steel

production after their use. All by-products generated (see page 13) are

recirculated or used as environment-friendly material in the production process

according to the closed loop recycling management. Traffic volume (external) Scrap delivery and finished products shipment are mainly realized by barge or

railway. As far as possible, the same barges and wagons are also used for

shipping the finished products

5.2 Energy aspects

Energy aspects are all activities, products and services having an influence on the

energy utilization and energy consumption. The main energy aspects were

determined on the basis of current and former data. An energy aspect is

regarded to be essential if it has a high portion of the total energy consumption

and has a potential regarding

Efficient energy utilization

Increased use of local renewable energies

The main energy aspects (main consumers of the respective energy carrier) are as follows: Current Area Process / activity Organisational unit Electric arc furnaces Melt-down of scrap Steel plant Rolling mills Rolling of billets in the rolling

mills Rolling mill

Ventilation De-dusting

Air pollution prevention Steel plant

Ladle furnaces Treatment of the molten steel Steel plant Natural gas Area / Unit Process / activity Organisational unit Pusher furnaces Heating of billets Rolling mill EAF burners Melting of scrap Steel plant


The biological diversity (land consumption) is no key indicator for BSW, as the

land consumption is limited due to the narrow headland and no additional area

can be added.

5.3 Key indicators

The improvement of the environmental performance is the concern to which

BSW direct their environmental management system. This is the reason why in

the previous BSW environmental declarations data regarding vital environmental

aspects like consumption of energy and resources, waste volume and emissions

were presented. Since the implementation of EMAS II these main aspects (key

indicators) are made concrete in key performance indicators. In the future, the

environmental performance shall be presented in a uniform and clear way.

Reference parameters (production capacity, billets or finished products in tons)

are provided to be able to reasonably compare improvements or trends over a

longer period. With a few exceptions (e.g. emission trading; start 2005) we have

chosen the reference year 2000, as from this moment a comparison to the

following years is possible. The reference year 2000 is defined with the index

number “100”. The key indicators are summarized in the following table and

presented and explained in the subsequent chapters.

18 | 19

5.3.1 Energy efficiency

Badische Stahlwerke GmbH has achieved a world class high standard in the

steelmaking process from the melt shop to the rolling mill. In the past, several

procedural improvements have been implemented which lead to considerable

energy savings for example in the field of electric steel making. While the energy

saving potentials in the field of steelmaking are rather limited today due to

physical basic conditions, there are still further potentials for savings in other steel

treatment areas like for example infrastructure, maintenance, supply and disposal

as well as administration. At the beginning of 2011 we have therefore

implemented an energy management system according to DIN EN 16001 for the

entire company in order to reveal possible potentials for savings in the different

areas.

The main energy carriers at BSW are

electrical energy, natural gas, coal

and diesel-fuel. Carbon is mainly

used for the generation of foaming

slag but will be considered.

The reference year chosen is 2009.

5.3.2 Material efficiency When buying raw materials and supplies BSW always makes sure that they

conform to its environmental policies. Purchasing guidelines were therefore

extended to include certain environmental aspects. Environmental protection is

also an important criterion for the evaluation of suppliers and their products.

Environmental considerations and safety criteria form part of the evaluation and

selection process because materials that can be detrimental to the environment,

if improperly used, often require special precautionary measures. The main raw

materials required for steel production are scrap, carbon, lime and various alloys.

Production and rain water are collected in one collection system at BSW. The

waste water quantity depends on the rain water quantity and is thus subject to

annual deviations. In 2011 the rain water quantities have additionally increased

due to new roof areas. We will certainly keep to the approved waste water

quantities.

Substantial investment in installations to improve the quality of the production

water/waste water (e.g. sand filter system, laminar separator, worm classifier)

have enabled BSW to meet or fall below the minimum legal requirements for

direct discharge. As a result of this investment, the flocculants used to improve

sedimentation in the sedimentation tank are eliminated with the solid material

and do not get into the waste water. The waste water is of such high quality that

BSW has been exempt from paying waste water tax since 1994. When handling

hazardous materials we make every effort to comply with the requirements of

the Water Resources Act and the directives on handling water-contaminating

substances.

5.3.3 Waste water and well water Waste water Various (partial) circuits in our water treatment operations enabled us to reduce

significantly the amount of additional water needed for production.

Consequently, the waste water quantity discharged into the Rhine decreased as

well.


To meet these regulations we have taken the following action:

Obtained a license to operate as a specialized plant as per Article 19 l,

Water Resources Act

Provided training in handling water-contaminating substances

Established a working committee for water protection

Defined tasks for specially designated water protection officers

Distributed leaflets to employees

Listed all potentially water-contaminating equipment

Purchased additional collection tanks for storage and transportation of

water-contaminating substances

Ensured that contractors working on site observe regulations

Well water BSW obtains water for production from deep wells located in the works area.

Water fulfills the following functions in the steel and rolling mills:

Steel mill: Cooling of melting furnaces

Cooling of molds

Cooling of billets (through spray risers)

Rolling mills: Cooling of rolls

Cooling of rolling stock

Means of transportation for mill scale

Cooling agent for machinery and electrical installations

The Fifth Amendment to the German Water Resources Act of September 23,

1986 defined plants' obligation to install water-saving technologies and circuits.

BSW consequently adapted its water management step by step to a system of

water circuits and has reduced the consumption of well water and discharge of

waste water.

22 | 23

Due to the increase of production cooling water quantities technical measures

were required in 2009 to reduce the fresh water quantity. Investment measures

of 4.5 m Euro have been implemented in 2010. It shows a considerable

reduction in 2010.

5.3.4 Waste

BSW commit to returning the waste materials generated during production to

the production process in terms of the German Closed Substance Cycle Waste

Management Act or to recycle them, respectively. BSW strictly adheres to the

principle of "avoidance before recycling before disposal". Waste like packaging

material is collected and separated on site before being passed on for recycling.

Non-recyclable components are passed on to the district authorities in

accordance with the waste handling by-laws. Waste requiring special monitoring

is handed over for recycling or disposal after obtaining the necessary approval.

A waste report and a waste balance for hazardous waste is prepared once per

year. The waste report gives information about the status of the waste

management at BSW. The waste balance serves as internal control instrument

and shall document the type, the quantity and the fate of the disposed of or

recycled wastes.

To improve the waste management situation at our site we have introduced the

Industrial waste Basically mixed waste, foil, wood, paper, plastics and packaging waste accrue at

BSW. BSW assigns the required waste disposal only to specialized waste

management facilities or EMAS certified companies; this is also valid for

hazardous waste

All industrial wastes at BSW are recycled. Hazardous Waste The above mentioned dusts accruing in the de-dusting system represent the

largest part of the hazardous wastes. The other hazardous wastes arising at BSW

are mostly non-chlorinated, PCB free hydraulic and machine oils, washing water

and old cleaning rags. They are used for material recycling or energy recovery by

the waste management enterprises. Small quantities of hazardous waste like for

example acids or bases are disposed of. With the commencement of the

compulsory for manufacturers, carriers and waste management companies. Metals for recycling Metals accruing for reutilization at BSW are for example copper cables, old motors and brass. Wastes as by products BSW has developed certain procedures and quality requirements and has thus

created the possibility to market some waste products as by-products. Those by-

products are slags, scale and refractory materials. The specific quantity of EAF

slag depends on the available scrap quality.

5.3.5 Emissions

Dioxin and furan emissions A BREF document published in March 2000 cites BSW as a reference for state-of-

the art technology (BREF = Best Available Techniques Reference Document on

the Production of Iron and Steel).

The development and installation of technology that significantly reduces the generation of dioxins and furans during scrap melting is one of BSW's prime achievements.

During the melt down process in the electric arc furnace, gases and dust

containing dioxins are generated. Dioxins and furans disintegrate at temperatures

of more than 700°C. As the melt has a temperature of more than 1,600°C all

dioxins and furans have disintegrated. In order to avoid regeneration during

normal cooling down (de novo synthesis) the off-gases are shock-cooled by

quenching.

A major problem with dust removing plants is burn holes in filter bags. BSW has

taken threefold precautions to ensure that its dust collecting facility operates

safely and effectively:

1. The gas is moist after being quenched with a mixture of air and

water, so sparks rarely fly right up to the filter bags.

2. The filter bags are made of special material, so a spark can only burn

a small hole.

3. The dust removing plant is continuously monitored so any problems,

even minute holes in a filter bag, are immediately detected and the

filter section affected is closed off. This does not adversely impact the

plant’s dust extraction performance because the system has around

15 % surplus capacity (a filter section corresponds to about 3 % of

the area).

BSW thus determines state-of-the art technology in electric steel making. The

BREF document states on page 308 (chapter 9):

„Operational data and economics: The post-combustion unit at ProfilARBED, L-

Differdange and at BSW, D-Kehl are operated without significant problems.“

26 | 27

Explanations ng: nanogram: 1 ng = 10-9 g corresponds to one billionth of a gram TE: Toxicity equivalents: all dioxins and furans are valued with factors ranging from 0.001 to 1, depending on their toxicity, and are represented as a sum Nm3: Standard cubic meter: to be able to compare gas volumes they are represented in a standard state (0 °C and 1.013 bar)

Carbon monoxide and dust in the steel plant: The specific amount of dust could be reduced in the course of the last few years

by means of different measures with regard to maintenance at the filter units.

In other words we have our processes under control and produce steel with a

minimum of emissions, especially dioxins.

The following graphic illustrates the success of our efforts:

Reduction of limiting values in the framework of modification approvals: Limiting value as of 1991 : 0.5 ng TE/Nm3

Limiting value as of 1994 : 0.3 ng TE/Nm3

Emissions as per the greenhouse gas emission trading act The steel plant is liable to emission trading. The CO2 emissions are calculated on

the basis of a balancing of the in- and output of carbonic materials, i.e. only

directly generated emissions (electric current is not considered in this context).

kg CO2/ t billets

In the first trading period of the emission trading system (CO2 trading) from 2005

to 2007 Badische Stahlwerke in Kehl were defined as a benchmark for electric

steel plants, i.e. we have the lowest CO2 emission for comparable plants. This

was approved by an independent expert. The reference year chosen is 2005, the

start of the first trading period.

28 | 29

Pusher type furnaces at the rolling mill Two pusher-type furnaces - one in each rolling mill - reheat the billets produced

in the meltshop and continuous casting plant to the required rolling temperature

of approximately 1,150 °C. Both natural and liquid gas can be used as fuel in any

ratio of mixtures. Until 1985 the furnaces were fueled with heavy oil and the

change of fuel has clearly improved emission levels and eliminated the risk of

water and soil contamination due to heavy oil storage.

The waste gases generated during pusher-type furnace operation are evacuated

through recuperators to preheat the combustion air and thus save energy. BSW

makes a special effort to charge billets into the pusher furnaces at as high a

temperature as possible to minimize fuel consumption. Waste gases are released

into the atmosphere from chimney stacks. The continuous measurement of

nitrogen oxides at the pusher furnace is realized since 2004; therefore, this year

is taken as reference year.

Noise prevention measures In 1976 the first noise measurements were carried out in the vicinity of BSW. As

a consequence, a 600 meter long and 10 meter high noise insulation dam

parallel to the steel mill was built and vegetation was planted between the dam

and the village of Auenheim. This project was carried out with the support of the

Technical University of Karlsruhe and was completed by 1983. In 1987 changes

in production and stricter environmental legislation prompted BSW to develop a

noise reduction concept in conjunction with a leading company in this field.

The following year BSW submitted the associated expert reports to the

authorities and made them publicly available. Planning of the measures to be

performed and a second revision of the prognosis takes nearly two years. A noise

reduction program was defined with the target to achieve the prognosed values

by 1995.

BSW has performed noise reduction measures for a continuous reduction of

noise emissions and noise immissions for 25 years. The achievements are the

result of the following measures like:

Erection of a noise insulation dam in Auenheim (1980)

Planting of vegetation in Auenheim (1983)

Construction of noise insulation wall in scrap yard (1990)

Construction of noise insulation wall in billet yard (1990)

Construction of noise insulation wall alongside steel mill (1992)

Construction of noise insulation wall in rolling mill (1993)

Improvement of noise production of furnace and casting bay

during the extension (2002)

as well as to a multitude of smaller measures which are not mentioned in detail.

In the environmental declaration 2003 we set ourselves the target to further

decrease the noise level of the billet yard by building a roof and at the rolling mill

by a complete reconstruction of the roof. A specialized company for acoustics

calculated on the basis of the drawings a possible noise reduction before

commissioning of the roof construction works.

The calculations revealed that emissions cannot be reduced to the full satisfaction

of BSW by installation or re-construction of the roofs.

In cooperation with specialized companies an essentially more efficient noise

protection wall was calculated for the boundary of Auenheim. Only the

installation of a noise protection wall will reduce immissions in the neighborhood

considerably and permanently. After having received the building licence

construction work started in the year 2006, and in 2011 the noise protection wall

was finished with respect to its height. The greening and designing of the noise

protection wall is about 75% finished. The eastside of the noise protection wall

will be finished in 2013/2014. In addition; we have initiated a 16-point plan for a

further reduction of noise levels in the plant and in the municipality of Auenheim

(level see Environmental program 2011-2014 target No.1). Due to the redesign

of the rolling mill a continuation of the 16-point program will only be possible

after completion of the modifications.

The objectives are mainly based on

Legal requirements

Results of eco-audits

Annual auditing of the management system

Result of management review

Site inspections

Environmental and energy audits

Evaluation of environmentally and energy relevant data

Need for action due to environmental and energy aspects

Proposals for improvement by employees

The total of all objectives make up the environmental and energy program.

The management of the company is responsible for the check-up and the

adjustment of the environmental and energy objectives. The current objectives

and the respective program are printed in the Environmental Declaration. The

financial means and the time frame are fixed by the company management.

The improvement measures are completed with responsibilities and dates and

integrated in the environmental and energy program. The figures stated in the

Environmental Declaration show that we already have a very high environmental

standard. The objectives determined in the last Environmental Declaration have

all been achieved.

Now we have set new objectives which will have to be put into effect.
