Revenue model

1. Demolition and deconstruction services: Project-based contracting for demolition, controlled deconstruction, industrial decommissioning, rehabilitation, and decontamination of buildings, infrastructure, and industrial sites. Revenue is earned through one-time service contracts with both public and private clients, priced per project based on scope, complexity, and site conditions. Services span from pre-project studies through to full on-site execution.
2. Circular economy and materials valorization: Revenue derived from recovery, resale, and recycling of materials recovered during deconstruction. Materials such as metals, concrete, wood, and urban equipment are sorted, processed, and either reintegrated into the client's new project or sold to secondary markets. Services include inventorying, selective stripping, conditioning, and sale or donation through channels including foot-of-site collection, Box Réemploi, and permanent or pop-up material recovery centers.

Core offering

Demcy provides integrated demolition, deconstruction, industrial dismantling, rehabilitation, and decontamination services for buildings, industrial sites, hospitals, and urban infrastructure across France. Its core delivery is supported by a circular economy pillar offering material reuse (Réemploi) and recycling (Recyclage) services, with a documented capability to valorize over 90% of deconstructed materials. Projects are executed under bespoke contracts managed by a single point of contact (interlocuteur unique) from feasibility studies through site execution, using a fleet of specialized equipment including long-reach excavators, mobile decontamination units, and remote-controlled demolition machinery.

Product overview

Demcy offers a unified portfolio of deconstruction and environmental services as a single brand under Eiffage Génie Civil. The core service offerings include controlled demolition, industrial dismantling, rehabilitation, and decontamination, which are supported by two complementary service pillars: reuse (Réemploi) and recycling (Recyclage). These services are delivered through a network of agencies throughout France, enabling the company to offer end-to-end solutions from preliminary studies through to work execution, with a strong focus on circular economy principles and sustainable development.

• Decontamination (Décontamination) Hazardous material removal and decontamination services for asbestos, lead, refractory ceramic fiber, mercury, hydrocarbons, and hexavalent chromium, including mobile decontamination units (UMD), clean rooms, air monitoring, and regulatory documentation. Delivered across buildings, industrial sites, hospitals, and infrastructure.
• Material Reuse (Réemploi) Inventory, selective removal, traceability, preparation, storage, and reintegration of recovered materials and equipment from deconstruction sites, including resale or donation via foot-of-site collection, Box Réemploi, and partner recovery centers.
• Material Recycling (Recyclage) Recycling of demolition waste including concrete, wood, metals (copper, steel, aluminum, scrap), paper, cardboard, plastic, and glass. On-site crushing and recarbonation of concrete to produce backfill, road sub-base, or new concrete aggregate. 97% of demolition waste is valorized.
