The European Union (EU) has issued a proposal to expand the scope of restrictions on eight polycyclic aromatic hydrocarbons (PAHs) in granules or mulches used in synthetic turf pitch infill materials.
The eight PAHs are:
• Benzo[a]pyrene (BaP)
• Benzo[e]pyrene (BeP)
• Benzo[a]anthracene (BaA)
• Chrysene (CHR)
• Benzo[b]fluoranthene (BbFA)
• Benzo[j]fluoranthene (BjFA)
• Benzo[k]fluoranthene (BkFA)
• Dibenzo[a,h]fluoranthene (DBAhA)
Under the draft regulation, the sum of these eight PAHs must be no more than 20 mg/kg.
The proposal was circulated by the World Trade Organization (WTO) on September 8, 2020, attached to WTO document number 20-6061. If adopted, it will expand the scope under entry 50 of Annex XVII of Regulation (EC) 1907/2006 ‘Registration, Evaluation, Authorization and Restriction of Chemicals (REACH).
Granules and mulches are used as infill material in various situations:
• Synthetic turf pitches
• Playgrounds (loose form)
• Sports application (loose form) – e.g. golf courses, athletic arenas, horse arena footings, nature trails and shooting ranges
Granules and mulches can be made from recycled or virgin materials but are often made from end of life tires (ELT). Entry 50 to Annex XVII of REACH does not currently regulate them as they are classified as ‘mixtures’. They are defined as:
• Granules – mixtures that appear as solid particles, 1 to 4 mm in size and are made of rubber, other vulcanized or polymeric materials
• Mulches – mixtures that appear as flake-shaped solid particles, with a length of 4 to 130 mm and a width of 10 to 15 mm, and are made of rubber, other vulcanized or polymeric materials
It is proposed that the draft document will be adopted in Q1 of 2021. The restrictions would then come into effect twelve months after the date of entry into force (mid-2022).
