BUILDING A FRESH FUTURE
FOR CONTAMINATED SITES
core activities
TOGETHER, WE NEUTRALIZE POLLUTION TO BUILD THE FUTURE
For more than 10 years, REMEA has been working for the good of the environment and its clients, by giving polluted sites a fresh future.

SERVICES FOR CONSTRUCTION
SITES
Remediation of waste water and optimization of spoil
Decontamination of ponds, effluents, and sludge on operational sites
Remediation of soil and groundwater,
both on and off site
THE GROUND IS A RESOURCE THAT SHOULD BE PRESERVED
Our services allow former industrial sites on the periphery of urban areas to be reused, thereby preserving the rural environment. By protecting the balance between urban and rural spaces, we are contributing to the local ecology.
We offer remediation solutions for operational sites and management of pollution migration so you can undertake your construction projects on safe ground.
As a subsidiary of the soil specialist Menard, we employ innovative treatment procedures in situ or on site. This limits off-site transfer of contaminated material, which can be costly from both a financial and an environmental point of view.
The decontamination of industrial sites is a major challenge for the previous user of a site, and for its future user, especially in terms of remedial costs and time schedules. Thanks to a wide range of remediation solutions, we can design and implement responses adapted to the constraints of your project. At our laboratory, we test and scale solutions, thus reducing the technical uncertainties.
We offer 360°, turnkey solutions: Demolition, remediation, decontamination, and geotechnical improvement to deliver platforms ready for construction, as part of the global delivery of reconversion projects.

OUR SERVICES AND RELATED TECHNIQUES
WATER AFFECTED BY SUSPENDED SOLIDS
• Sizing and on-site supply of the appropriate mobile wastewater treatment units
• Analytical follow-up
POLLUTED SOILS
• Soil characterization• Excavation mapping• Optimization of waste treatment outlets,
resulting in cost savings• Supervision of waste evacuation including
regulatory traceability• Turnkey service for the excavation and removal
of contaminated soils
SLUDGE
• Sludge treatment, drying/dewatering and disposal or recovery
ODORS AND DUST
• Environmental follow up on site and around sites (digital measures or quantitative captors)
• Impact reduction: control of the airflow, masking agents, atomizers, work under depressurized tents…
SERVICES FOR CONSTRUCTION SITES
With increasingly dense urban environments, construction companies regularly have to deal with pollution of soils and groundwater, which, during the construction phase, can have an impact on: • Pumped groundwater • Excavated soil • Site sludge • The local environment, in terms of odors
and dust
We make our expertise available to you to deal with these issues, advising you on the best strategies to adopt.
• Operational engineering with a commitment to results
• Modular treatment units designed for each site
• Connected systems allowing a reliable monitoring

Industrial activities may generate on-site effluents and sludge that must be treated and removed. We facilitate industrial processes by handling:• cleaning of sludge from settling tanks and
ponds• treatment of effluents• sludge dewatering as a continuous process• on site pre-treatment of sludge or waste
We meet all the necessary environmental, safety and quality standards: ISO 14001, ISO 9001, OHSAS 18001, and we can rely on a team of engineers and project managers with full knowledge of the regulations governing sites.
• A multi-technique approach• Process and equipment engineering capability• In-house supply of dredging, dewatering, and
physical-chemical treatment equipment• Integration from the design phase of health
and safety concerns

HEALTH, SAFETY, ENVIRONMENT
HEALTH, SAFETY, ENVIRONMENT
As a responsible company, we put health, safety and the environment at the heart of our concerns.
Our objective is zero accidents, so our safety policy is built on the commitment of both management and every employee towards a profound change in behavior.
On our sites, we regularly monitor the level of pollutants in the air to check that it is in line with collective and individual protective measures to preserve the health of our staff and of all the stakeholders involved.
REMEA has OHSAS 18001 and MASE certification. OHSAS 18001:2007
ENGINEERING SOLUTIONS
We have a team of highly qualified, multi-disciplinary engineers to provide state-of-the-art expertise in: • The analysis of problems• Designing the best treatment
strategies • Laboratory testing• Digital simulations• Implementation of the recommended
solutions
The choice of treatment solution is dictated by the expected outcomes for each approach: Chemical, biological, physical, thermal. It also takes into account the costs and associated technical and financial considerations, along with health and safety issues.
INNOVATION AND RESEARCH & DEVELOPMENT
We invest heavily in the area of innovation. Either as part of our in-house research, or in collaboration with our main partners, our R&D program involves: • the continual quest for new processes capable
of degrading, neutralizing, or extracting pollutants • the improvement of techniques and materials used
to enhance pollutant-reagent contact, which is the key to the success of any treatment
We have a unique portfolio of proprietary expertise and patents.
