Abengoa halts its main Spanish ethanol plant again

MADRID, Sept 23 (Reuters) - Spanish engineering and energy company Abengoa (ABG.MC: Quote, Profile, Research) said on Sunday it had suspended bioethanol production at the biggest of its three Spanish plants because it was unprofitable.

It cited high grain prices and uncertainty about the national market for ethanol.

The plant, in Salamanca province in central Spain, is half owned by food group Ebro Puleva (EVA.MC: Quote, Profile, Research) and stopped for several months earlier this year for similar reasons.
