In a major advancement for sustainable construction, scientists have created a cement-free soil solidifier from industrial waste. By combining Siding Cut Powder and activated by Earth Silica, an alkaline stimulant from recycled glass, scientists produced a high-performance material that meets compressive strength standards exceeding the 160 kN/m construction-grade threshold and eliminates arsenic leaching through calcium hydroxide stabilization. The technology reduces landfill volumes and carbon emissions, offering a circular solution for infrastructure development worldwide.

Reducing travel speeds and using an intelligent queuing system at busy ports can reduce greenhouse gas (GHG) emissions from oceangoing container vessels by 16-24%, according to researchers. Not only would those relatively simple interventions reduce emissions from a major, direct source of greenhouse gases, the technology to implement these measures already exists.
