Concrete is one of the largest industrial sources of CO2, responsible for roughly 8% of global emissions. This article from Building Design looks at experimental approaches to lower the carbon footprint of concrete, including alternative binders, carbon capture during curing, and recycled aggregates. It profiles researchers and startups testing these methods in real projects, not just labs. The piece focuses on the practical challenges of scaling these alternatives. Many low-carbon concretes face issues with cost, supply chain readiness, and building code approval. The article gives a grounded look at which experiments are moving toward commercial use and which still need years of testing. For anyone tracking industrial decarbonization, this is a useful snapshot of where concrete innovation stands right now.
