4meeting with WssTP, september 27 2010

The SRA of ESTEP answers the

following challenges

Development of Safe, clean, energy-efficient and cost-effective technologies

Reducing the CO2 emissions directly in steelmaking and indirectly by offering suitable steel solutions

Promoting conservation of resources, recovery of wastes and societal value of materials ( SOVAMAT)

Contributing to the development of Energy sources for the future

Attracting and securing highly skilled people

5meeting with WssTP, september 27 2010

ESTEP’s Roadmap on

sustainable use of resources

6meeting with WssTP, september 27 2010

Resources: issues and R&D areas

Iron ores and scraps

• Optimising the use of lower grade ores

• Recovering Fe units from in-plant residues in

dedicated tools ( field for R&D and demo projects)

– BF and BOF dusts and sludges

– Electric Arc Furnace (EAF) dusts, oily mill scales

• Optimising scrap recycling

– Today 40% of crude steel within EU27 is produced by

the scrap + EAF route

– Still a potential to increase gradually this rate up to 50%

in the next 20 years thanks to larger available quantities

and better control of scrap qualities

7meeting with WssTP, september 27 2010

Resources issues and R&D areas

Resource & Energy efficiency (1)• Resource & Energy efficiency partnership ( REP)

– Energy Intensive Industries ( EIIs) are key actors in today’s

European Economy

– Recently was established informally a R&D network with

material producers ( steel, non ferrous, glass, cement,

chemicals, paper..) and equipments suppliers ( represented

by Eunited) named REP

– Steel industry is in favor to reinforce this REP R&D network,

publishing an position paper ( oct 2010) in order to :

• Exploit the potential of REP in European research, fully integrated

in the Framework Programme ( FP7 and FP8)

• Strengthen the role of REP in the PPP Factory of the Future

• Promote demonstration projects and deploy key enable technologies

• Coordinate skills development within REP

8meeting with WssTP, september 27 2010

Resources issues and R&D areas

Resource & Energy efficiency (2)

• Energy efficiency in the steel industry

– adoption of the SET-Plan methodology, with a single format

of the definition and the follow-up of energy consumptions

– To address both integrated BF/BOF and scraps+EAF plants

– Identification and evaluation of potential gains

• Carbon needs for reduction

• Energy efficiency of the equipments and processes : roadmap

« intelligent steel manufacturing » in the frame of the PPP FoF

• Energy recovery

• Maximizing the use of scraps

• Process yield improvement

• Application of steel products : transport, construction, steel for energy

9meeting with WssTP, september 27 2010

Resources: issues and R&D areas

Ecological services

• Ensure the water supply for the long term– Improvement of water intake, water discharge, close loop

concept, minimization of water use/waste

– EU steelmakers active in the Worldsteel water project

• Monitor and improve the air quality

• Prevention of the noise

• Steel industry very active in the BREFs and

IPPC approach.

• Preservation of the biodiversity and the land

quality & use

• Ecological village : synergy between industries

and communities. 10meeting with WssTP, september 27 2010

Resources: issues and R&D areas

Global warming

• Medium term approach

– Strong link between energy efficiency and GHG issue:

Energy savings induce reduction of CO2 emissions

– Increase scrap recycling : scrap route emits by the factor

5 significantly less CO2 emissions, including carbon for

electricity

• Long term approach: the ULCOS project

– 2 demonstrations projects are planned so far:

• the BF with TGR( Top Gas Recycling) and CCS with 50%

reduction of CO2 emissions

• Hisarna ( direct reduction with pure oxygen ) with 80% reduction

11meeting with WssTP, september 27 2010

Sustainable water management ( 1)

2 main production routes :

-Blast furnace & converter- Scraps + Electric Arc Furnace

12meeting with WssTP, september

27 2010

Sustainable water management ( 3)• EU 27 steel production is around 200mt/year, before

the crisis with 60% by Blast Furnace route and 40%

by scraps+ Electric Arc Furnace Route.

• The BF/BOF (Blast Furnace/ Basic Oxygen furnace)

route is much more demanding in water than the EAF

route.

• For the 120mt/y of crude steel with BF/BOF , the net

consumption of water is between 1 and 5m3/ ton of

steel and average at around 2.5m3/ton of steel.

• Total intake is around 30m3/ton , so total discharge

water is 27.5m3/ton. Some plants are working in

close loop. 13meeting with WssTP, september 27 2010

Sustainable water management ( 4)

• In steelmaking water is used for

– Cooling ( the major part), especially for the Blast

Furnace, the coke cooling, the continuous casters and

the hot rolling.

– Cleaning ( waste gas cleaning) , mainly for Coke Oven

gas and Blast furnace gas

– Steam use

– Other chemical use such as HCL pickling, emulsions

for rolling, degreasing of steel sheet surface etc…

14meeting with WssTP, september 27 2010

Sustainable water management ( 5)

• Within the World Steel Association, a water

management working group was set-up in 2008.

• The purpose is quantified the amounts of water

used, the different treatment methods, the rate of

reuse of treated water, the quality of discharged

water .

• Exchanges on techniques applied and best

practices.

15meeting with WssTP, september 27 2010

Sustainable water management ( 6)

• Topics of interest between ESTEP and WssTP

– Water and energy

– Water sourcing

– Water treatments

– Water related costs

– Water qualities ( depending on the processes)

• Trends for discharged water ( like Chemical Oxygen

demand, Suspended materials)

• Softening optimisation

• Health & Safety ( ie legionella )and environment

• Sludges and brines

- Global water management for industry 16meeting with WssTP, september 27 2010
