As the construction industry shifts to using "green" products for a sustainable future, scientists are recreating the most basic materials such as concrete to make that goal a reality. This article notes developments of three innovative building materials: a phase-change material called "bioPCM" gel; Solidia's plastic-based concrete alternative; and Novacem's carbon-negative magnesium oxide-based concrete alternative, which absorbs more carbon from the air during its production process than it releases.
