Mechanism of bio-carbonation on leaching behavior: a case study of coal gasification slag-based binder

Puntos clave

• Leaching behavior improves significantly with bio-carbonation, enhancing the stability of coal gasification slag.
• Important findings indicate a reduction in leaching by approximately 30%, which suggests better environmental safety.
• Analysis of coal gasification slag binders through controlled laboratory setups demonstrates effective bio-carbonation mechanisms.
• This work highlights the potential of bio-carbonation methods to mitigate leaching, calling for further exploration in real-world applications.
