Abstract The global olive oil production for 2010 is estimated
to be 2,881,500 metric tons. The European Union countries
produce 78.5%of the total olive oil, which stands for an average
production of 2,136,000 tons. The worldwide consumption of
olive oil increased of 78 % between 1990 and 2010. The
increase in olive oil production implies a proportional increase
in olive mill wastes. As a consequence of such increasing trend,
olivemills are facing severe environmental problems due to lack
of feasible and/or cost-effective solutions to olive-mill waste
