Used disposable diapers are mostly landfilled or burned, but up to 8% of the volume of concrete and mortar to make a basic house could be replaced by recycled disposable diapers. A study has shown that shredded and cleaned diapers could replace 10% of the sand in concrete for structural columns and beams in a 3-story house; 27% of the sand in concrete for columns and beams in a 1-story house; 40% of the sand in mortar for partition walls; and 9% of the sand in mortar for floors and garden paving. Moving forward with this could help with climate change. Hopefully governments and people will be able to get over the ick factor.
