While yesterday it was in the air, today it is present in the water and tomorrow it will be in the soil. What is it? A drop of water, a gas bubble or a grain of sand?
There is no simple answer to this question. Water, air and soil are strongly related. That doesnt make it easy to classify a solution for an environmental problem.

The Trevi strategy is using a wide approach for each environmental problem, involving a team of environmentalists, all experts in their own environmental field. Our first concern is to achieve a maximum reduction at the source, which has been our main objective ever since the beginning in 1992.

Thanks to an enthusiastic team of people with different specialities, Trevi can handle most projects from start to finish with its own experienced staff. Indeed, the diversity of employees is one of the keystones of Trevi: laboratory assistants, environmentalists, technical designers, welders, mechanical engineers, electricians, programmers and project engineers, all working together for a better environment.

Every project, big or small, is continuously increasing our know-how, resulting in a growing competence for the next project. As a result, Trevi offers a wealth of experience in environmental advice and technology in a wide range of environmental fields. All this is illustrated on this website.
