Eni and Hera together for the circular economy: from spent vegetables oils the biofuel for waste collection vehicles


Eni and Hera, companies long engaged in promoting a circular economy model through the continuous technological and organizational development of their respective businesses, have today signed a partnership aimed at transforming used vegetable oil into biofuel to fuel the Hera waste collection company vehicles.

The agreement provides that exhausted vegetable oils for domestic use, such as those for frying, recovered by Hera through approximately 400 road containers and in about 120 collection centers, will be sent to the Eni biorefinery in Venice, in Porto Marghera, the world's first example of conversion of an oil refinery into a biorefinery, which will transform it into green diesel, a completely renewable product which constitutes 15% of Enidiesel +. The biofuel will feed the Hera company vehicles for the collection of urban waste. In the experimental phase Enidiesel + will be used by some thirty large vehicles, in order to optimize the environmental benefit, in the Modena area.

The agreement signed today extends the virtuous circle already initiated by Eni with the multi-utility companies of Turin, Venice and Rome and whose tests have already demonstrated important benefits in terms of air quality, economic and industrial. In fact, compared to traditional diesel, Enidiesel + has a renewable component that reduces polluting emissions by up to 40%, saves fuel consumption by around 4% and reduces engine maintenance costs. The same technical improvement parameters deriving from the use of the biofuel will be subject to joint monitoring by the two companies, in collaboration with the CNR Institute of Motors.

To further support the initiative, Hera has chosen to enhance the collection of vegetable oils by introducing 300 new dedicated containers in the areas served. In 2017 alone, 800 tons of waste vegetable oils were collected, recovered and then processed to be valued as lubricants or through energy recovery. An increasingly widespread service which, by encouraging correct recovery, also aims to prevent behavior, such as the spillage of oils in the sink, which is harmful to domestic pipes and water purification plants.
