Oregon State University (OSU) and Sandia National Laboratory have received a three-year, $540,000 grant from the US Department of Energy to explore capturing carbon dioxide from industrial emissions and sequestering it in a mineralized form in 3D printed building materials.

Pavan Akula, assistant professor of civil engineering in the OSU College of Engineering, will team up on the project with researchers from Sandia, the Indian Institute of Science, the Indian Institute of Technology Roorkee, and two industry partners – Graymont and Verdant Building Alternatives.

According to Pavan, the researchers’ goal is to take a sector of the economy that accounts for a large portion of the carbon dioxide emissions and make it significantly greener.

“The construction industry is responsible for generating 13% of global CO2 emissions,” said Pavan. “In recent years, 3D printing technology for concrete has been gaining popularity in building construction as it is a more sustainable alternative – it reduces both waste and transport costs. However, most 3D printing of concrete still relies only on traditional materials that are really carbon intensive.”

According to OSU, Portland cement, developed in England in the early 1800s, is the most common type of binder used in concrete. It is usually produced by mining, grinding, and heating clay and limestone in industrial kilns to temperatures as high as 2,820 degrees Fahrenheit. The process alters the materials’ chemistry and creates ‘clinker’ – cement’s main component – and also generates carbon dioxide.

“We plan to capture CO2 emitted from the lime and cement industries and develop sustainable binders capable of storing and mineralizing the captured CO2 in printed building components such as walls,” said Pavan. “Our project aims to develop technologies and materials that can significantly reduce the carbon footprint of materials used in 3D printing.”

Something especially important, he added, as demand for concrete is expected to keep rising as trends toward urbanization continue globally. “Shrinking the carbon footprint of cement-based construction materials is imperative if we’re to hit decarbonization and climate targets set by the Paris Agreement.”
