What they say

Director Industry and Environment

Advising our industrial clients is always a pleasure for us as engineers. We revel in the contact with our clients and fellow stakeholders and we take great pleasure in analysing processes and proposing ways of managing risks and environmental issues. Our first industrial project dates from 1987, but we still work tirelessly and continuously to reap the fruits of our industrial culture and incorporate changing practices and the evolving regulatory context.

Director Regions and Environment

We are fortunate to be able to travel the length and breadth of the regions in France in the course of the assignments entrusted to us. Obviously, we view the places we visit through the trained eyes of urban planning professionals and compilers of environmental assessments on different projects. But for us it is also always a pleasure to meet the stakeholders in the regions, whose commitment commands our respect and who we endeavour to guide and assist in their desire to show their authority/organisation or company in the best light by means of a harmonious development which incorporates the sustainable in the management work they accomplish every day.

Director Technical Polluted Sites and Soils

Whether your project involves the sale or acquisition of real estate, stock transactions or purely financial investments, the application of an increasing number of ever-more complex regulations in relation to the environment, and workplace health and safety can transform a simple investment into a real ordeal in legal and financial terms.
As specialists in environmental due diligence, we enable you to manage all the risks involved in your investment.

Director Occitanie

When we observe the way waste management has changed over the last 10 years, and we understand the challenges that face us going forward, we draw enormous satisfaction and a great sense of ambition from our profession.  The theme of waste is revealing of the reality in our regions in many respects. That allows us to remain aware and invested in the environmental significance, but also the economic and social importance of waste management. Ensuring those aspects remain at the heart of our assignments is an ambition which can only enhance the standards of quality we aim to achieve in our work.

Director Nouvelle Aquitaine

Players involved in the redevelopment of polluted sites need to be able to easily identify the well-established specialist service providers who can meet their needs, and comply with the legal and regulatory requirements in force and the state of the art. Special consideration must also be given to the issues of public health, safety and environmental risks.

That is why the Ministry of Ecology, Sustainable Development and Energy (MEDDE), introduced certification for services to polluted sites and soils, issued by the French National Laboratory for Metrology and Testing (LNE).

Soler Ide holds LNE Polluted Sites and Soils certification. The certification covers Domains A and B of French Standard NF 31-620 concerning the provision of services in respect of polluted sites and soils:

  • Domain A: Studies, Assistance and Checks
  • Domain B: Rehabilitation engineering works

For the contracting party, LNE certification is the assurance that the services will be provided in a manner which is safe and trustworthy.
