US: AquiPor Technologies has developed a concrete additive that makes concrete permeable to water, while filtering 97% of suspended solids. Additionally, the additive filters up to 82% of 6PPD-q, a tyre-derived pollutant threating urban waterways. The additive is suitable for production using established precast and ready-mix concrete production processes.
AquiPor Technologies has completed demonstration projects deploying the additive and is now working with partners on its commercial scale-up.
