(by Cristiana Missori) (ANSA) - ROME - The Polish economy grows by an average of 3.5% a year and its global exports grow, too (about half of its GDP). In particular, exports to Italy are growing: in 2014, exports more than doubled, reaching a turnover of about 7.2 billion. The Polish Embassy in Rome awarded the four best companies in the country: in the construction industry, electromechanical products, raw materials and food products. The Prize ''Centaur'' is a sort of ''Academy Award'' for the best exporting companies (to Italy). The first one is Oknoplast - a leading European manufacturer of PVC doors and windows - which has been active in the Italian market for 9 years (exports last year, 35 million euros). Pesa Bydgoszcz, Poland's largest train-manufacturing company, won the award for its electromechanical products. As a provider of raw materials, the company PolskiKoks SA has been awarded for reaching a sales volume of about 4 million tons of coke and about 16 million tons of coal per year (28,000 jobs). In the food sector, the award was won by Pini Poland Sp. Z o. o., which is among the top three producers of sausages and smoked meats in the EU (exports to Italy, about 61.5 million).(ANSA).
