Buildings consume 40% of raw material and primary energy and generate 35% of industrial waste worldwide, making this sector play a main role in raw material depletion, energy consumption and carbon emissions which provoke great environmental impact and worsen Global Warming. Latin American countries including Mexico have the world's highest urbanisation rate (84%) but lack effective construction and demolition waste (CDW) management to thrive in regenerative sustainability, climate change mitigation and post-pandemic economic recovery. This work applies the Spanish current model to quantify on-site 61 Mexican social housing CDW with surveys to workers and supervisors as an additional source of data. The results of the case study show that social housing consumes 1.24 t.m-2 of raw materials and produces 0.083 t.m-2 of CDW. Cement-based, ceramic and mixed CDW represent 83.44% of total CDW. When considering inert soil as a recyclable resource, 78% of the remaining CDW ends in landfills and only 22% of it goes to recycling plants. The implementation of this methodology will deliver sustainable CDW management in Mexico, by minimising CDW production, promoting related legislation and allowing replacement of current construction materials for eco-efficient ones. Furthermore, these data can broaden the Spanish coefficients of the construction resources that become CDW to build an internationally sourced database.
