01 · The essentials

In 30 seconds

Hire wherethe plant never stops

What we recruit

The operations, site and plant management directors, project directors, then maintenance and HSE managers, process and flue gas treatment engineers, and 3x8 and 5x8 shift leaders of energy-from-waste plants.

Who it is for

EfW operators, public service delegates, energy companies, biomass and anaerobic digestion developers, manufacturers that produce their own heat and steam.

How

By direct search : these profiles are in post and do not read job ads. Each candidate is assessed by an engineer from Mines Saint-Étienne and AgroParisTech on furnace operation, the boiler, flue gas treatment and ICPE.

The proof

23 hires for the IDEX group, including the two management roles at the Villers-Saint-Paul EfW plant and the first SRF cogeneration plant in Brittany.

02 · The problem

What a vacant directorship costs

A plant that never stopscannot wait for its director

At an energy recovery site, an empty post does not stay empty for long: someone covers it on an interim basis, and the availability of the plant pays the price.

  1. Availability drops

    An unplanned shutdown means untreated tonnage, contractual penalties and lost electricity or heat output.

  2. ICPE rules leave no room for approximation

    Flue gas treatment, emission limit values, relations with the DREAL: the director must have lived these issues, not just know about them.

  3. The talent pool is exhausted

    On the Villers-Saint-Paul assignment, three months of searching reached almost every EfW site director in post in France. No job ad reaches them.

  4. The sites are far from towns

    Industrial or rural areas, 3x8 and 5x8 shift patterns, on-call duty: each constraint shrinks the pool of possible candidates further.

Site management roleson new sites and operating sites

For the IDEX group, we hire the heads of plants that exist only on plans as well as those of plants already up and running. Two different hires: a start-up is not an operation.

The director of an SRF cogeneration plant that does not exist yet

The context
A new plant worth €70m, including €14.5m from ADEME: 40,000 tonnes of SRF a year, 85 GWh of heat and 20 GWh of electricity. Start-up planned for 2027, 14 jobs created.
The challenge
A newly created post, with no predecessor, in a Breton area where this profession is rare. The brief is a site start-up brief, not day-to-day operations: the search has to be national.
What we did
The search ecosystem existed before the assignment: more than 400 energy site directors mapped in six months. The candidate is approached and called back the very evening the assignment opens.
The result
François Wawczyniak, then director of a biomass and SRF plant in Finistère. Offer made and accepted on day 25.

Hiring a site directorwithin 3 weeks

A 1-hour scoping session and a scorecard, mapping of the search ecosystem, a shortlist within 10 days, a hire within 3 weeks. The 3 weeks run from scoping to the chosen candidate, offer accepted, when the five key success factors are in place. The candidate's notice period, often three months for a manager in post, then comes on top.

  1. Day 1

    A 1-hour scoping session and a scorecard

    Deliverable: 3 to 5 reasoned profiles

  4. Within 3 weeks

    A hire within 3 weeks by direct search

    Two interview rounds at most, with the direct manager. The package and the counter-offer are prepared before the final interview: the offer goes out within 24 hours and the chosen candidate says yes.

    Deliverable: Offer accepted, start date set

On an EfW siteThe mapping covers every site director in post in France and a 60 to 100 km radius around the plant for shift teams. The technical interview covers operation, availability and ICPE.

  • Replacement guarantee of 3 to 6 months
  • Onboarding follow-up over 90 days

Frequently asked questionson energy recovery

Which recruitment firm for an energy-from-waste plant (EfW)?

A recruitment firm specialised in EfW, that knows how an energy-from-waste plant is run: furnace and boiler operation, flue gas treatment, ICPE compliance, availability rate. Volta Executive is a Parisian executive search boutique whose historical core business is energy recovery: 23 hires for the IDEX group, including both directors of the Villers-Saint-Paul EfW plant, 368 EfW site directors mapped in France, and an SRF cogeneration director hired on day 25 in Brest. Every finalist is assessed by an engineer from Mines Saint-Étienne and AgroParisTech. Shortlist within 10 days, hire within 3 weeks through direct search, under an exclusive mandate.

How do you recruit in anaerobic digestion and biogas?

Recruitment in anaerobic digestion is a niche market under double pressure: few candidates trained specifically in running digesters, and demand accelerating with the France 2030 plan (target of 10 TWh of biomethane in 2030). Profiles that master the biology of the anaerobic process, biogas recovery systems (cogeneration, grid injection), digestate management and regulatory constraints (ICPE, GRDF connection) are scarce. Volta Executive identifies them through direct search in operating units, agricultural and industrial projects and wastewater treatment plants. Shortlist within 10 days, hire within 3 weeks, candidate's notice period on top.

What is the difference between biomass recruitment and anaerobic digestion recruitment?

Biomass (energy wood, green waste, agricultural residues) and anaerobic digestion (fermentation of organic matter) call for different skills. Biomass centres on combustion, the boiler, solid fuel supply and flue gas treatment. Anaerobic digestion relies on the biology of the anaerobic process, biogas treatment (H2S, moisture), cogeneration or grid injection, and agronomic use of the digestate. Candidates are rarely interchangeable between the two sectors. Volta Executive has hired in both areas and knows how to assess the real skills of each.

How do you recruit an EfW site director?

Recruiting an EfW site director relies on direct search. The best profiles are in post and do not respond to job ads. You have to map the energy recovery sites, identify the executives currently working, then approach them directly. The candidate must be able to run a continuous operation, maintenance, ICPE compliance and the plant's availability rate. These profiles combine a solid technical background (furnace operation, boiler, turbine, flue gas treatment) with operational leadership ability. At Volta Executive, the shortlist arrives within 10 days and the hire is concluded within 3 weeks by direct search, provided there is a reply within 48 hours and an exclusive mandate; the candidate's notice period comes on top. For this niche profile, the mapping of the search ecosystem is wider. Volta Executive has hired several EfW site directors and deputy directors since its creation.

Which profiles does an energy-from-waste plant need?

An EfW plant needs profiles that combine a grounding in combustion with the demands of continuous production. Site director, operations director, maintenance manager, energy performance manager, process engineer, flue gas treatment engineer, control manager, shift leaders. What these profiles have in common is the ability to keep availability high while meeting ICPE and safety constraints. They are scarce and rarely actively looking for a job.

How do you recruit in biomass and cogeneration?

Recruitment in biomass and cogeneration runs into two difficulties. Sites are often in rural areas, which limits the local talent pool. And the skills expected (biomass boiler, plant operation, fuel supply, availability rate management) are scarce. Direct search among candidates already in post at comparable plants is the only reliable method. That is what Volta Executive does, notably on recurring biomass shift leader assignments.

Why use a specialist firm for an ICPE-classified site?

An ICPE site demands constant regulatory rigour. Flue gas treatment, emission limit values, DREAL relations, process safety. A bad hire at the head of such a site exposes the operator to environmental, legal and availability risks. A specialist firm assesses the candidate on concrete command of these subjects, not only on their CV. A generalist firm does not master the vocabulary, the operational reality or the specific stakes of an energy recovery site.

What is the difference between a generalist firm and an energy specialist firm?

A generalist firm knows how to run a recruitment process but does not master the trade. It cannot tell a good operator from a good communicator, nor assess command of a furnace, a biomass boiler or a contractual availability rate. Volta Executive is led by an energy engineer, a graduate of Mines Saint-Étienne and AgroParisTech. The technical assessment is done by someone who has lived plant operations. Engineers before headhunters.
