New Commission proposal puts EU on path from hero to zero to address global mercury crisis

Brussels, 8 February 2016 – The European Commission has quietly launched its new mercury package on 2nd February 2016 [1], moving the EU a step closer towards ratifying the Minamata Convention, a UN treaty to stamp out mercury [2]. While the European Environmental Bureau (EEB) welcomes the new package, its content fails to meet even the lowest of expectations.

We are deeply disappointed with this bare-bones proposal from the Commission,” said Elena Lymberidi-Settimo, Zero Mercury Campaign Project Manager.  “Under the guise of Better Regulation, it is putting the EU on an embarrassing path from hero to zero in addressing the global mercury crisis.  The proposal effectively ignores a public consultation, progressive industry voices, and even the scientific findings of its own impact assessment.”

The package sets out plans to update existing EU law in line with the internationally-agreed goals to limit mercury supply, use and emissions under the treaty. Despite the EU having played a leading role in the formation of the Convention, the new plan to put it into practice appears to have fallen victim to the EU’s Better Regulation agenda. The package was already delayed by over a year – pushing back the UN treaty ratification process [3] – and ambition is thin on the ground.

The new proposals follow the lowest-cost approach across the board rather than promoting higher environmental protection, according to the EEB. Elsewhere, other ‘new’ proposals are simply repackaged existing EU legislation, and some of the treaty requirements seem not to be covered by the proposal at all.

Mercury and its compounds are highly toxic to humans, especially to the developing nervous system. Mercury transforms to neurotoxic methylmercury, which has the capacity to collect in organisms (bioaccumulate) and to concentrate up food chains (biomagnify), especially in the aquatic food chain – fish, the basic food source for millions of people.

Recent studies indicate that mercury levels are increasing in tuna by 4% per year, correlating with the continuing rise in mercury in the global environment. If steps are not taken to reduce global mercury pollution, levels of mercury are expected to double by 2050 [4]. 

The EEB will now be calling on the European Parliament and Member States to recognise the gravity of the situation and adopt measures that will reduce and eliminate all unnecessary uses and releases of mercury.

Notes to editors:

[1] Ratification of the Minamata Convention on Mercury by the EU

http://ec.europa.eu/environment/chemicals/mercury/ratification_en.htm

[2] The Minimata Convention on Mercury http://www.mercuryconvention.org

To meet the Convention requirements, six areas are identified which need additional legislation at the EU level:

  • The import of mercury

  • The export of certain mercury added products

  • The use of mercury in certain manufacturing processes

  • New mercury uses in product and manufacturing processes

  • Mercury use in artisanal and small scale gold mining (ASGM)

  • Mercury use in dental amalgams

[3] NGOs Letter to the European Commission - The EU and its Member States should rapidly ratify the Minamata Convention on mercury, 14 December 2015

[4] Over the past year, it has become more apparent than ever that the global mercury crisis is affecting the food we eat.  Mercury concentrations in tuna are increasing at a rate of 3.8 percent or more per year, according to a new study that suggests rising atmospheric levels of the toxin are to blame. This correlates with recent studies showing that mercury levels in the global environment are set to double by 2050, if current pollution and deposition rates continue.

In polyurethane manufacture, for many applications, the catalysts of choice for catalysing the reaction between a polyol and an isocyanate composition, i.e., for hardening or curing polyurethane (PU) materials, have long been organic mercury compounds. This is because, for a wide range of polyurethane materials, these catalysts provide a robust and desirable “reaction profile” characterised by:

• an initial induction period in which the reaction is either very slow or does not take place, which continues for sufficient time to permit the “system” (combination of polyurethane materials and catalyst) to be mixed and cast (or sprayed); and

• a subsequent rapid reaction period during which the product cures, taking on its final properties (shape, hardness, flexibility, strength, etc.).

Like any catalyst used in PU elastomer systems, the mercury catalyst is incorporated into the polymer structure and remains in the final product. Over time – and accelerated by exposure to harsh environments, UV, abrasion, etc. – the polymer structure breaks down and mercury is released.

Mercury in PU products already attracted attention some years ago. According to an investigation by the Minnesota (USA) Department of Health, some PU elastomer flooring manufactured from about 1960 through at least 1980 contained up to 0.1% mercury in phenylmercuric acetate or other organo-mercuric salts that were used as catalysts (Reiner 2005, as cited by MDH 2006). Ambient mercury concentrations in school gyms ranged from 0.13 to 2.9 Pg/m3, and in 5 of 6 gyms was above the RfC level of 0.3 Pg/m3 established by US EPA as the exposure level below which no adverse health effect is expected (MDH 2006). A separate investigation in Ohio (USA) showed that PU elastomer floors in schools also emitted mercury is excess of the 0.3 Pg/m3 RfC level (Newhouse 2003).

It is estimated that 300-350 tonnes of mercury catalyst may be used globally in PU elastomer applications, of which some 60-105 tonnes in the EU (industry communications; SRI 2006). If one assumes the mercury catalyst is added to a system at an average of 0.5-0.6%, then approximately 55,000 - 65,000 tonnes of PU elastomers globally are catalysed with mercury each year. Assuming the global market for PU elastomers is 1.6 million tonnes, this suggests that around 4% of that global market uses mercury catalysts. As a percentage this is not high, but it represents over 100 tonnes of mercury consumption worldwide, and 20-35 tonnes of mercury consumption with PU elastomers in the EU27+2. The mercury catalyst mainly ends up in the final product, and it is roughly estimated that the mercury consumption in PU elastomer end products corresponds to the consumption during production of 20-35 tonnes within the EU27+2.

Tin and amine catalysts are alternatives to Hg catalysts for some PU elastomer applications, titanium and zirconium compounds have been introduced for others, while bismuth, zinc, platinum, palladium, hafnium, etc., compounds are marketed for still others. In fact, known mercury-free catalysts could be used for nearly all elastomer applications, but some reduction in the key performance characteristics of activity, selectivity, catalyst lifetime, etc., may have to be accommodated until the best system is identified for a given application. (Shepherd 2008).

As suggested, a large number of Hg-free catalysts for PU elastomers have been developed as alternatives to mercury – the large number reflecting the fact that there does not appear to be a “drop-in” substitute for mercury catalysts that can be used in so many different systems, that confers similarly desirable curing properties, and that is so forgiving and easy to adjust to the needs of the user.

Despite these challenges, it should be stressed that perfectly viable substitutes to mercury catalysts are already in use for over 95% of PU elastomer systems, and have been in use for many years.

The cost of most mercury-free catalysts is quite competitive with the typical mercury catalyst cost, and even more so if one takes account of waste disposal costs, environmental and other customer concerns. The cost of Thorcat 535 has increased significantly in recent years, and is presently in the range of €40-50/kg, compared to €25-35/kg for medium-priced mercury-free catalysts, and €10-20/kg for cheap mercury-free catalysts (IMCD 2008). A bismuth catalyst would be fairly close to the cost of Thorcat

Relevant legislation and NGO policy work

In the EU

In 2010 the Norwegian authorities submitted a report (report Annex XV) to the European Chemicals Agency (ECHA), asking for the restriction of use of phenylmercury compounds as catalysts in polyurethane systems,  

The report is open for consultation and comments are due by 24 March 2011.

The Risk Assessment and Socio-economic Analysis Committees of ECHA (RAC, SEAC) will give their opinions on the suggested restriction taking into account comments submitted by the interested parties during the public consultation (see Art 70 and 71). [expected by March 2011].

Furthermore, interested parties will have a possibility to comment the draft opinion of SEAC. [expected summer-autumn 2011]

For more information, about the timetables and procedures, please, consult the new ECHA website at http://echa.europa.eu/reach/restriction_en.asp

Please see the  EEB comments on Phenymercury compounds that were submitted during the public consultation that was concluded on the 24 March 2011.
