McGill University researchers use pulp and paper waste to scrub carbon from emissions

McGill University researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. According to a university press statement, the technique they’ve pioneered using the Canadian Light Source at the University of Saskatchewan not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.

“We are one of the first groups to combine biomass recycling or utilization with CO₂ capture,” said Ali Seifitokaldani, Assistant Professor in the Department of Chemical Engineering and Canada Research Chair (Tier II) in Electrocatalysis for Renewable Energy Production and Conversion. The research team, from McGill’s Electrocatalysis Lab, published their findings in the journal RSC Sustainability.

McGill University’s statement explains that capturing carbon emissions is one of the most exciting emerging tools to fight climate change. The biggest challenge is figuring out what to do with the carbon once the emissions have been removed, especially since capturing CO₂ can be expensive. The next hurdle is that transforming CO₂ into useful products takes energy. Researchers want to make the conversion process as efficient and profitable as possible.
