Revenue model
- 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.
- 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.
