Habitat for Humanity partnered with Engineering for Change to research strategies and technologies that can improve circularity in Mexico’s housing sector. Drawing from desktop research and semi-structured interviews with more than 15 experts in the local housing ecosystem, the investigation determined four main strategies: (1) improving the reuse and recycling of building materials within its value chain; (2) developing building materials by using recycling plastics; (3) shifting towards innovative construction systems that use industrialized production processes; and (4) increasing the use of natural and bio-based materials that have less of an ecological footprint.
