HVO producers embrace circular economy – The cases of Eni and Neste



It appears that HVO producers are abandoning palm oil, primary feedstock up to now, and are being seduced by used oils. This trend is a clear consequence of the implementation of circular economy principles in this sector. Let us review two recent examples: the announcement on Eni and CONOE last week and the launch of the Neste MY Renewable Diesel earlier this year.

The case of Eni

Eni and CONOE (the National Consortium for the Collection and Treatment of Used Oils and Fats in Italy) have just signed a Memorandum of Understanding to promote and increase the collection of vegetable oils that will supply Eni's biorefineries (see press release). The agreement was presented officially last week in Rome (see program of the event).

The agreement also envisages joint ventures between Eni and CONOE, as well as with local public administrations and public waste collection companies, to promote the collection of increasing amounts of oil waste produced by Italian households, which are currently almost entirely wasted. According to the press release, CONOE has increased waste collection from 15,000 tons in 2002 to 65,000 in 2016. The figure of the last year corresponds to 23% of potentially collectable.

What are the biorefineries that will benefit from the agreement?
This plant is the first refinery in the world to be converted into a biorefinery. Since May 2014, the plant produces green diesel, green naphtha and LPG and has the capacity to generate green jet fuel. It is currently predominantly fed by palm oil, supplied exclusively from certified sources in line with industry standards. This will be partially replaced by used vegetable oils and animal fats.
2. Gela biorefinery
Eni is converting other refinery into a HVO biorefinery in Gela (region of Sicily). As the Venice biorefinery, it will be based on the EcofiningTM technology developed by eni and UOP.

Once the Gela refinery begins operations in 2018, Eni’s capacity to process vegetable oils will be approximately one million ton per year. So, it will have the capacity to acquire all products from CONOE oil-purchasing companies on the national market. The Consortium estimates potential savings up to 3.13 kg of CO2 equivalent per ton of renewable diesel produced and used as fuel.

The case of Neste

In January, Neste launched a renewable diesel made entirely from waste under the brand name Neste MY Renewable Diesel at select service stations in the Helsinki region (see press release). Its production is based on Neste's proprietary NEXBTL technology which can be used for producing renewable diesel and other renewable products from almost any waste fat or vegetable oil. The feedstock selection available has been successfully expanded to more than 10 raw materials and Neste is engaged in continuous development work to further expand it.

According to the information provided by the company, the product enables up to 90% lower greenhouse gas emissions throughout the life cycle of the fuel compared to conventional fossil diesel. For instance, Neste's renewable diesel is already extensively used in California where it helps cities and counties to reduce greenhouse gas emissions from traffic. Companies such as Google and UPS in the United States and DB Schenker and Lassila & Tikanoja in Finland have also decided to reduce their carbon footprint with Neste MY Renewable Diesel.
