The cement industry is one of the world’s largest producers of atmospheric carbon dioxide. The reason is that cement’s calcium carbonate releases the greenhouse gas. Now researchers have shown that they can replace up to 10% of the cement in mortar mixtures without harming the strength of the widely used masonry paste. The cement’s replacement is environmentally friendly, to boot: a waste product from olive oil production (Environ. Sci. Technol., DOI: 10.1021/es200968a).
