Italy's antitrust authority said on Tuesday it had imposed fines exceeding 32 million euros ($37 million) on energy company Eni and its plastics unit Novamont for abusing a dominant market position in the production of plastic bags.

Eni SpA agreed to sell a 20% holding in its renewable arm Plenitude to Ares Alternative Credit Management for about €2 billion ($2.3 billion), its second sale of a stake in the unit.
