this Directive urged
the member States to establish a 10% biofuel share in the motor fuel
market by 2020. Its adoption led to the construction of many biodiesel
plants in Spain; in 2010, there were 45, but one year later,
only 31 plants were working at 25% of their production capacity
(4.5 Mt/year) (CNE, 2012). Nowadays, most of the current 44 production
plants are at a standstill.
