Lead industry’s contribution to a sustainable future is key theme at ILA’s record-breaking conference
Delegates to the 18th International Lead Conference (Pb2013), in Prague, have heard how lead and its products are making a significant contribution to a sustainable modern society.
Over the two days (20-21 June) of the conference The Future of Lead: Meeting the Challenges and Seizing the Opportunities run by the International Lead Association (ILA), a record number of delegates heard speakers highlight the importance of the lead industry economically and socially and the continuous improvement made by companies to reduce worker exposures and minimise environmental emissions.
Opening the first session, Geert Krekel, Managing Director of ILA member Campine, said: “The lead industry’s current image is outdated and undeserved. It already has a good story to tell in terms of its positive contribution to society – it just needs to start telling it more proactively and confidently.
“It is an industry that is focused on the responsible management of a material that delivers huge benefits in its existing applications and has significant potential to contribute further to a sustainable society.”
Some of the key messages delegates heard were:
- More than 95% of lead-acid batteries are now recycled
- There is an increasing global demand for energy storage solutions with lead-based batteries at the forefront
- 75% of new vehicles in Europe are equipped with Start-Stop systems using advanced lead-based batteries
- Advanced lead-acid and UltraBatteries are reducing CO2 emissions and play an important role in renewable energy storage for the wind and solar energy industries
- Architectural lead sheet is ‘the new eco building material’
- Regulatory challenges are significant, but companies continue to find innovative solutions to improve health, safety and environmental performance.
Presentations by analysts Helen Matthews (Wood MacKenzie,) and Huw Roberts (CHR Metals) highlighted significant and sustained growth in the global lead industry over many years, driven largely by increasing demands for energy storage solutions – a trend which is forecast to continue into the future.
Michel Baumgartner, of EUROBAT, explained how in Europe the lead-acid battery continued to be the dominant chemistry. However he highlighted that fuel economy and CO2 reduction targets will play a big role in future technologies adopted by car manufacturers.
Today more than 75% of new vehicles placed onto the European market are equipped with Start-Stop systems using advanced lead-based batteries. “We can therefore not speak anymore of new markets and technologies, but of a very advanced mass market already,” added Mr Baumgartner.
Dr David Wilson, President of the Advanced Lead-Acid Battery Consortium (ALABC), spoke of the important work of the ALABC in supporting the development of these advanced batteries and of the impressive performance expected from the next generation of batteries.
It was a message emphasised by Kevin Smith, of the East Penn Manufacturing Company, who demonstrated how the benefits of advanced lead-acid and UltraBatteries extend beyond CO2 emissions saving in vehicles and played an important role in renewable energy storage for the wind and solar power industries.
Delegates also heard from several speakers on a range of practical actions being taken by the lead industry to continuously improve the management of lead in respect of health and the environment. This ranged from a presentation on the independent environment and health research sponsored by the lead industry through the International Lead Zinc Research Organization (presented by Dr Craig Boreiko of ILZRO) to innovative waste management technology solutions reported on by Mark Stevenson of Ecobat Technologies Asia.
Community engagement was recognised to be an important activity for the lead industry and Richard Deane, of Teck, explained how the Canadian lead producer had partnered with the local community in Trail, British Columbia, to lower the blood lead levels of children and tackle wider social health issues as well.
Lead’s environmental credentials were a recurring theme throughout the event, and ILA’s Dr Alistair Davidson, demonstrated the major contribution made by recycling, reporting that more than 95% of lead-acid batteries were now recycled, helping to make lead the most recycled major commodity with a recycling rate of 75% for the lead industry as a whole.
The environmental benefits of another product, architectural lead sheet, were also highlighted by Doug Weston, CEO of the UK Lead Sheet Association, who concluded that lead should be considered as the ‘new eco building material’ based upon its low carbon footprint and lower lifecycle costs compared to other products.
Against this positive backdrop the lead industry also recognised the increasing regulatory pressures it faced globally. Dr Steve Binks, ILA Regulatory Affairs Director, said that the industry would be able to meet these challenges so long as it continued its existing efforts to go beyond regulatory requirements by adopting a culture of continuous improvement in EHS controls.
Co-operation with organisations such as the Blacksmiths Institute, who presented on legacy pollution challenges in developing countries, will be important in rebuilding trust in the lead industry and the work undertaken by the International Lead Management Center described by Brian Wilson was a tangible demonstration of this commitment.
Summing up ILA Managing Director Dr Andy Bush said “The success of Pb2013 confirmed the event’s place as the leading forum for the lead industry and its users around the world to discuss the future for lead. This year’s event clearly demonstrated that while the lead industry will undoubtedly face many challenges in the coming years, it is committed to demonstrating its value to society and indeed further enhancing this through a variety of continuous improvement initiatives.”

Lead exposure to workers in the European and North American lead industry is well managed and reductions continue to be recorded
Delegates to an international Lead Occupational Exposure Workshop, in Prague, (June19) organised by the International Lead Association (ILA) heard how data collected recently by the Lead REACH Consortium showed that blood levels in the majority of European workers were below those set to support the EU REACH Regulation at 40µg/dl (1) and well below the current EU Binding Limit Value of 70µg/dl. A similar picture is also evident in North American lead workers.
Aggie Kotze, ILA-Europe’s REACH Manager, told the workshop: “The blood lead dataset we have collected is robust and representative of all EU sectors manufacturing or using lead and lead compounds. It demonstrates that if companies adopt risk management measures specified in REACH Chemical Safety Reports, workplace exposures will be under that generally accepted to result in occupational health issues.”
Data was collected from primary and secondary lead producers, as well as users of lead in the manufacture of batteries, lead sheet, lead oxides and stabiliser compounds.
The workshop provided a platform for companies involved in the mining, manufacture and use of lead to exchange information on the latest developments in global regulations, science and industry initiatives to manage worker exposure to lead.
In his presentation Michel Baumgartner, of EUROBAT, announced that its membership which represents the major European battery manufacturers, along with US battery manufacturers represented by Battery Council International (BCI) had now set a voluntary target to reduce blood lead levels for all employees below 30µg/dl blood by the end of 2016 . This demonstrates that this sector recognises the benefits in continuous improvement by establishing targets below the limits set by current European Union and U.S. legislation.
“This is evidence to regulators that industry can be a credible partner and deliver results on its own,” said Mr Baumgartner.
The workshop was the first organised by ILA and was supported by the Association of Battery Recyclers, BCI and EUROBAT. The international audience also heard speakers from companies such as East Penn Manufacturing, Exide Technologies, Johnson Controls and RSR Corporation give examples of how developments in health and safety practices, and widespread adoption of initiatives such as behavioural based safety programmes, had led to significant reductions in employee blood lead levels.
Examples of successful company safety schemes that were presented included rigorous personal hygiene practices, an emphasis on hydration at work, personal counselling for employees with elevated blood lead levels and incentives for employees to maintain low lead in blood levels.
Improvements to plant design and engineering controls were also illustrated including the effectiveness of supplied air islands to reduce dust and the increased use of automation.
ILA Managing Director, Dr Andy Bush, said: “This workshop has shown that there is a genuine global commitment across the lead industry to adopt safety practices that deliver continued reductions in blood lead levels in its workers.
“Delegates can take away from the workshop plenty of practical information and the ILA will be working in partnership with other lead industry associations to ensure continuous improvement remains high on the industry’s agenda.”
