The finding delivered to the clientFor an EfW plant director role, the strictly EfW talent pool no longer exists in France. Yet an incineration furnace, a cement kiln and a heavy chemicals boiler rely on the same combustion physics and the same ICPE regime: when the target does not exist in volume, our job is to say so and propose a reasoned widening.
05 · The method
How we work
Four principles,kept on every assignment
The mapping before the first message
A census of France's EfW plants, biomass heating plants and SRF units, then of the leaders in post at each. This is the work that lets us tell IDEX, figures in hand, that the strictly EfW talent pool is exhausted.
Fully direct approach, zero job ads
At this level of role, the right profiles are not looking. A job ad would have yielded nothing and would have exposed the assignment. 1,284 messages for the Villers-Saint-Paul site alone, all personalised.
The brief reopened when the market says so
At Villers-Saint-Paul, a candidate approached for the deputy role proved to be cut out for the top job: the brief was reopened with the industrial management.
Follow-up does not stop at the signature
Onboarding check-ins held with the hire and then reported back to IDEX: 90 days on leadership assignments, up to a year for shift leaders in training.
The candidate hired
Florian did what few still do: he saw the person behind the skills and the experience. An approach built on trust and precision that I strongly recommend.
