A team of Japanese researchers has developed a novel geopolymer-based soil solidifier using siding cut powder (SCP) and Earth Silica (ES), both derived from industrial waste. 

Beyond structural performance, the study addresses key environmental challenges in the construction sector. By partially replacing traditional cement, responsible for up to 8% of global CO₂ emissions, with recycled materials like SCP and ES, the approach significantly reduces the carbon footprint. It also promotes the reuse of industrial waste that would otherwise be destined for landfills.

Durability tests revealed high resistance to freeze–thaw cycles, sulphate attack, and alkali–silica reactions, ensuring long-term performance under demanding conditions. This innovation represents a decisive step towards circular economy practices in construction, with direct implications for the sustainability of urban and infrastructure developments.
