There is therefore no question of injecting the frying oil that you have at home into the tank yourself. These are processing companies that must take care of the oil, which will be filtered and transformed into biodiesel to be usable as fuel. And as the specialist points out, in the diesel that we buy at the pump (B7)we find 7% biodiesel created with frying oil.
We must not believe that we can replace all of our fuel consumption
“It remains interesting because it is waste. But we must not believe that we can replace all of our fuel consumption with frying oil.“, relativizes the professor at the Polytechnic School of UCLouvain.
Certainly, the approach is advantageous both economically and ecologically. By reusing used oils, oil is not produced exclusively to create biodiesel. But don’t get carried away: the quantities of frying oil are limited. “It is estimated at five to ten liters per person for an average European population. And so imagine this quantity transformed into biofuel… it remains minimal compared to what we consume as fuel over a year“, concludes Francesco Contino.
From a practical point of view, consumption remains similar to that of conventional diesel. And from an ecological point of view, the approach is not necessarily greener, as Christine Rousselle explains to our colleagues from TF1: “Oil is hydrocarbon” indicated the specialist to French journalists, before specifying that we do not produce less CO2 with oil than with diesel.
It would also seem that the pollution is more important in winter since the oil being more viscous in extreme cold, it can produce more particles according to her.
