Pirelli Researching the Use of Rice Husk Ash in Tyre Compounds
From an ecological point of view, the new Pirelli Cinturato P7 offers three headline benefits – a CO2 emission reduction of up to 4 grams per kilometre driven, 30 per cent lower noise emissions and a 4 per cent fuel saving. Pirelli’s clincher (particularly aimed at current and potential OE customers) is that it is already in position to meet the targets set by the new EU regulations that are due to take effect from 2011 and that it does this without compromising on wet or dry performance. However, none of this explains how the company is able to achieve these goals.
In mid-February, Pirelli gave details of how its 2009 – 2011 industrial plan means the company will have an increasingly “green” focus. In particular Pirelli committed to developing a series of new materials that for use in tyre compounds. One particular silica rich material is rice husk ash (RHA). Pirelli is already (as far as the technological requirements are concerned) in a position to use this material in tyre production this year. However, the material is currently the subject of a large scale viability study focusing on the availability of the kind of tonnages needed for tyre industral scale tyre manufacturing. Tyres & Accessories understands that Pirelli already has research and development teams in place in Brazil and the areas surround Milan, which just happen to be some of the best rice production areas in the world.
