Our rice factory is located in Olen, in the province of Antwerp. Our Associates there proudly manufacture and distribute Uncle Ben’s® rice to more than 35 countries – in fact, 94% of the production is destined for export, mainly within the European region. Built in 1977, it is the only factory of its class outside the United States and it is Mars Incorporated’s global dry rice expertise centre. It has its own R&D and Engineering Centre, where a team of Belgian and international experts develop new technologies. Various innovations have seen the light of day in Olen including the invention of boil-in-bag rice in 1983, followed by 10-minute rice in 1987, ready to heat microwaveable rice in 2002 and the new “Rice and Grains” range in 2015.
