The new EU Legislation provides a global reference for green tire development towards a more environmentally friendly world.

Usage of conventional RPO that contains carcinogenic substances should be reduced as much as possible in order to provide low level emissions of the 8 Polycyclic Aromatic Hydrocarbons (PAH) into the environment.

In 2010, the EU REACH Regulation 1907/2006 Annex XVII entry 50 was enforced. The Regulation states that RPO containing more than 1 mg/kg of BaP or more than 10mg/kg of the sum of 8 PaHs must not be placed on the market and used for the production of tire or parts of tires.


In 2012, an additional EU Legislation on tire labelling (EC/1222/2009) requires a label on each tire with information on fuel efficiency, wet grip and external rolling noise.

The above legislations were enacted to improve safety and increase environmental and economic efficiency. This affected tire manufacturing globally.


In response to this challenge, ENERCO came up with a patented cutting edge innovative technology to produce TDAE that complies with all the EU Legislations and beyond.

Enerco is currently researching a newer RPO that will be more efficient and economical for all stakeholders.



Directive 2005/69/EC (PAHs in tires) is published by EU Commission.



EC 1907/2006 Annex XVII, entry 50 for Extender Oils :

  • Benzo (a) Pyrene / BaP < 1ppm.
  • 8 PAHs < 10 ppm.
  • Or PCA < 3% wt.
  • Aromaticity of oil in vulcanize rubber compound < 0.35, Bay Proton (ISO 21461)
