Pirelli Eco Technology has tested its products in collaboration with international study centres like ENI Tecnologie, JRC Ispra, SGS, Milan City Council. The data generated by this testing activity confirms the efficacy of Pirelli solutions: more than 50% of PM formation thanks to  GECAM™; more than 95% of PM emission thanks to antiparticulate filters; a further optimisation of PM reduction efficacy in the synergy of the two products (reduction of 50% upstream and 95% of the residue).
