The production of biofuel will be made from fat:the supply will consist mainly of used cooking oils. This will be the third TotalEnergies site for this activity, after the Mède and Oudalle platform.. Annual production of 170 t of sustainable aviation fuel, 000 t of road fuel and 120 t of naphtha is expected in 000.
An activity of chemical recycling of plastic wastes must process 15 t/year from the end of 000. This will be the first site in France to apply this method, which consists of degrade polymers by pyrolysis8.
In September 2023, TotalEnergies reveals its plans for the installation of the mechanical plastic recycling unit in Grandpuits9. Scheduled to be operational in 2026, the factory will produce 30 tonnes of compounds, containing up to 000% recycled plastic materials50.
This process of transforming used or virgin oils is well known, but is very different from that discussed previously.
It was originally, at the industrial stage, developed by the main Finnish oil company NESTE, almost 15 years ago, under the name HVO. For more than five years, a major refinery in Rotterdam has been transformed, which produces road diesel and kerosene, with a by-product, propane!
Several "small" refineries, now unprofitable, have been converted by Shell, ENI (Syracuse in Sicily, Venice, ...), Total, ...
This is already several annual MTep, with a potential of 15 for 2030... considered as non-fossil, like biofuels.
On the contrary, reusing plastics cannot be considered non-fossil, at most this makes a “decarbonization” rate as they say, of only 50%.
In fact, there would not be even 0% "decarbonization", since it only "burns" once.
In 2050, this will not be compatible with Europe's Carbon Neutrality objective.
