Holcim hosts Decarbonisation Accelerator Demo Days

3D-printed custom formwork and AI-powered supply chain software were among the new technologies on display during the annual Holcim Accelerator Demo Days at Lyons, France. Nine start-ups from seven countries came together to explore breakthrough solutions to reduce carbon emissions at production, material, design and construction level.

During the Demo Days event, the start-ups pitched their solutions and demonstrated an MVP (minimum viable product) to stakeholders ranging from corporate executives to investors, as well as a jury including representatives from corporate partners. Participating startups included SAEKI, presenting a system for robotic manufacturing of 3D-printed custom concrete formwork, and Low-Carbon Materials, presenting a carbon negative lightweight aggregate that can be used to produce net-zero concrete blocks. The field also featured software-based solutions, including from ThroughPut AI, which uses AI-powered supply chain software that draws on existing industry data to accelerate material flow, optimising costs and reducing CO₂ emissions. iNex Circular presented a digital tool to locate waste sources in a given area and then identify potential partners and suppliers.
