Who we are
PRO‑JEM, your technical partner for industrial projects
For over 30 years, PRO‑JEM has supported companies in machine design, project management, and installation development. Our expertise is built on diverse assignments across industries — CBR, SUEZ, AGC, MONDELEZ, BRUSSELS AIRPORT, EXIDE, TATA STEEL, COSUCRA, ISCAL SUGAR, SAINT‑GOBAIN… — and driven by a constant passion for technical innovation.
As a human‑scale firm, we combine responsiveness, proximity, and multidisciplinary know‑how. We work with SMEs, public entities, and industrial groups in a spirit of partnership based on trust, listening, and commitment.
Technical expertise in waste recovery, energy and environmental solutions
Since 1992, we’ve been developing treatment and recovery solutions for a wide range of waste types: organic (green waste, wood, bark, sludge…), inert (concrete, stones, bricks), non-hazardous industrial waste (NHW), screening rejects, polluted soils and dredging sludge.
In 2005, we designed the BIOTOP’R ventilation system for green waste composting, offering precise control of fermentation and emissions. It can be integrated into both new projects and existing platforms.
Our expertise also covers process optimization, industrial ventilation, noise control, metal construction, and civil engineering supervision.
Since 2019, we’ve specialized in energy management, now a key driver of industrial performance. Drawing on this experience, we provide reasoned technical opinions, in professional or legal contexts, and guide you toward the most appropriate solution for your specific needs.
Mechanical engineering, custom design and advanced simulation
We intervene on production lines to enhance performance, reduce nuisances, or develop custom machinery.
Our designs are created using Solidworks Premium and Solidworks PDM, ensuring realistic renderings and clear plan sharing for manufacturing and assembly. With Solidworks Simulation, we validate the mechanical integrity of structures and components through finite element analysis.
Our broad expertise, advanced design tools, and agility ensure fast delivery of technical solutions that are simple, reliable, and perfectly suited to your needs.
Project management, full oversight and single point of contact
We oversee your projects from the preliminary phase through to the end of the warranty period, managing technical, commercial, and budgetary aspects. Acting as your single point of contact throughout development ensures consistency and clarity. Our field experience is valued by our clients’ technical teams.
