Eni said its unit Ecofuel had reached an agreement with FRI-EL Greenpower, a Gostner family holding, to buy FRI-EL Biogas Holding, but did not provide any financial details of the deal.
The deal is part of Eni's broader decarbonization strategy, which aims to eliminate all emissions from industrial processes and products by 2050.
The news comes the day after an Italian court cleared Eni and Shell of charges related to a major oil exploration deal in Nigeria in which $1.1 billion allegedly ended up in the pockets of corrupt politicians and middlemen.
