Hi everyone, I am trying to learn how to compare the embodied carbon of concrete with natural aggregate vs concrete with onsite recycled aggregate. I found CarbonStar, which provides the methodology. But I don’t know where to source the emissions factor for recycled aggregate. Would a custom EPD need to be generated?
Probably a silly question but I’m more familiar with the vertical building world where recycling concrete onsite for aggregate isn’t common. I’m hoping the contractors have more context from horizonal infrastructure projects.
