Pirelli Eco Technology S.p.A. – Technologies for Sustainable Development

Pirelli Ambiente

Pirelli Eco Technology operates with considerable success in the sustainable development technology sector, with the objective of drastically reducing the particulate emitted by diesel engines and power stations. The company is a member of the European Emulsion Fuel Manufacturers’ Association (EEFMA) and the Italian Particulate Filter Manufacturers’ Association (AIFP).

Eco-sustainability forms the DNA of Eco-technology’s products like the GECAM, the white diesel™ and Feelpure™ antiparticulate filtering systems, described below.

GECAM, the White Diesel™

GECAM™ - patented by the Group - is an emulsion of water (10%) in diesel oil for use in vehicles and heating systems that reduces particulate emissions by 50%.

The tests performed on GECAM™ by the European Commission Joint Research Centre in Ispra and Eni Tecnologie Laboratories showed reductions of over 50% in particulate emissions, 5-6% in nitrogen oxides, and over 30% in carbon monoxide.

Pirelli Eco Technology received a Special Award for the GECAM™ emulsified diesel and its innovative solutions in sustainable transport at the 2006 World Renewable Energy Congress (WREC), an international conference held by the University of Florence and the ABITA Centre (Architecture, Bioecology and Technological Innovation for the Environment).

The sales of Gecam for 2007 has consolidated in the passenger transport, waste collection and mining sectors.

Feelpure™

Feelpure™ è is an exhaust gas treatment system capable of reducing particulate emissions by over 90%, for diesel vehicles already in circulation (via retrofit) with a mass of over 2.5 tonnes.

Feelpure™ is made up of three elements:

  1. A particulate filter in porous silicon carbide (SiC) fitted in a stainless steel can inside the exhaust silencer.
  2. An additive to be added to ordinary fuel, which allows for the complete combustion of the carbonaceous particulate previously trapped by the filter (a process of regeneration).
  3. A control unit that monitors the entire system, which detects counterpressure at the exhaust and the exceeding of alarm thresholds. It doses the additive to be added to the fuel on vehicles with this kind of feature. Recent tests, conducted by Eni Tecnologie Laboratories, the European Commission Joint Research Centre in Ispra and the University of Biel under the VERT programme, have shown reductions of over 90% in mass particulate and 99% in finer particles, over 90% in carbon monoxide and up to 69% of unburned hydrocarbons.

The sales of antiparticulate filtering systems rose sharply in 2007, with over 1000 systems sold to more than 40 customers operating in the public transport, and in the mining and construction sectors. Nine of these customers are industrial vehicle/bus dealers or major industrial vehicle repair shops that have installed and sold the systems on their customers’ vehicles.
