Eni and RenOils to boost collection of used cooking oil for biofuel production

Eni and RenOils, the Italian national vegetable and animal oils and fats Consortium established in 2016 to ensure the correct management of the collection, transport, storage, processing and reuse of vegetable oils and animal fats, are promoting the recovery of used cooking oils (UCO) for biofuel production.

Eni currently makes use of approximately 50% of the used cooking oil available in Italy and, in part thanks to RenOils-member regeneration companies, will extend its capacity to produce high-quality biofuel from this waste in the company’s bio-refinery in Venice, at Porto Marghera, and soon also in Gela.

The goal is to increase collection and proper disposal, since used oils from households are currently wasted almost entirely. Around 75,000 tonnes of waste food oil were collected in 2018, almost exclusively from the food service and industrial sectors, which represent just 25% of oil produced in Italy, which in turn totals around 280,000 tonnes per year.

The majority comes from homes, and goes down the drain for the most part, since most people don’t know that using the sewage network to dispose of cooking oil can have serious consequences for the environment.

As well as clogging domestic drains and the network as a whole, increasing maintenance costs, disposal through the sewage network impairs the correct operation of the purification systems and increases those costs too.

One liter of oil generates up to four kilograms of sewage sludge which then needs to be treated as waste, can arrive at aquifers and make the water undrinkable and pollute surface water, harming the ecosystem, flora and fauna. If it ends up in water, it forms a film that prevents the passage of sunlight, causing huge damage to the environment.

RenOils aims to make an efficient contribution to the Italian system for recycling used oil and to boost collection. There are 254 member associations and companies from the supply chain to date, from food oil producers to recycling and waste recovery organisations.

The Consortium acts collectively to achieve the environmental targets established by the Italian Ministry of the Environment (by which it was recognised in 2018) for the sector.

In collaboration with Tor Vergata University of Rome, RenOils has produced the first used vegetable and animal oils and fats monitoring system for the sector (R_O_S) which operates on a geographical basis and can be used on a web platform. This tracking is fundamentally important for the purposes of the agreement with Eni for reusing vegetable oil to produce biofuel.
