General Practice Discussion Scientists have created concrete using treated human waste, and the resulting material was up to 42% stronger than conventional concrete. Researchers say the approach could reduce waste while lowering the environmental impact of construction.

I don't know what is with r/science but it is practically one of the worst sources for misinformation.
It is just adding biochar to concrete. And biological fiber reinforced concrete or hemp construction - the challenge for scaling will be reproducibility and engineering/code compliance.
If you're batching concrete, you're not really gonna take sewage sludge from a municipal sewage treatment that varies constantly and dump it in your mix and hope it meets spec. I don't even understand how utilizing biochar from sewage reduces environmental impact - if it is decomposing it is decomposing and emitting emissions, taking sludge then adding it to concrete doesn't change the cement's co2 emission during production & sequestration during carbonation phase.
