With its business spanning multiple sectors in Corsica, the Petroni Group recently acquired a Vario 939 for its company STOC Specialising in waste management and treatment, this group has been working with professionals, companies and public bodies for over 20 years and has become a major player on the island in this sector.
Established in 1926 by Jules Petroni, the Group of the same name is today one of the major players in Corsica's public construction industry. At almost 90 years of age, the company has grown exponentially and now owns four companies specialising in each sector of the construction industry. Firstly, we have SNT specialising in public construction work, earthworks and structures; then there is ADIMAT, specialising in lifting, handling, transportation and rental; SCOFI, which also specialises in the production of aggregates and concrete; and finally STOC specialising in waste management.
The Group has dozens of employees in total spanning every part of the business.
STOC invested €7 million over a period of 10 years in this site south of Aléria, which handles all the waste from Upper Corsica. For this type of construction there are a number of conditions to follow, especially from an environmental point of view. Divided into 8 chambers each with a storage capacity of around 15 months, the planning of each chamber follows a precise and controlled process. The main objective is to avoid polluting the groundwater from the percolating waste seepage. To avoid this, each chamber is equipped with a passive barrier and an active barri.
Two layers safeguard the quality of the soil and groundwater on the site and in the surrounding areas. The passive barrier consists of a mixture of clay and bentonite while the active barrier is composed of a geomembrane.
It is in the making of the passive membrane that the Vario 939 comes into its own, bringing in the mixer to create a homogeneous mixture of clay and bentonite. Stéphane Laurosch-Cheney, one of the Group's managers, explains the reasons behind the acquisition: "We chose the Fendt Vario 939 for its versatility and transmission precision. Until now, we were mainly working with public construction equipment that was generally "mono-tasking"; with the arrival of this tractor we can consider a wider range of jobs and make more intensive investments. Exposed to variable working conditions, mainly because of the nature and moisture of the soil, the 390 hp of the tractor is applied by the 2.5 m rotor working at an average depth of 40 to 50 cm. With a forward speed shown in m/h instead of km/h the Vario transmission unleashes every bit of precision and intelligence through its TMS control and limit-load control to compensate for varying terrain without any need for driver intervention.
Jean-Baptiste Alberti, the head driver of the Fendt mixer, found the equipment intuitive to get to grips with. "Unlike the equipment used on public sites, like loaders or shovels, I was initially surprised with how many options the tractor has in terms of settings and its different operating modes. A little reluctant at first, I quickly realised that it was as easy to drive as any car, and as for comfort, the public construction equipment comes nowhere near. The cab's so comfortable and silent!". With a slight smile, he continues, "To be honest, I think other drivers are starting to get jealous...". Topping much awaited list, the versatility and modest fuel consumption of this tractor would stand out in a conventional public construction environment where the low hand-operated accelerator and fuel truck still prevail.
