ECT is part of a dynamic circular economy in which inert excavated soil is reused. This soil comes from building and public works sites.
Our development projects promote biodiversity and quality of life. They are put to different uses depending on the local issues at stake: landscape parks, reforestation, soundproofing mounds, photovoltaic power plants, agricultural land raising, urban farms, golf courses, sports and leisure grounds and facilities, etc.
