Seeking: Biological Approaches to Solidify Saturated Soils

Spread the love

A yet2 client is seeking approaches to aid in the handling of large volumes of slurry-like materials like saturated soils by solidifying and binding particles, desaturating it to produce a product that is much easier to handle and store.

Guidelines and Constraints

Biological approaches often has issues of activation and inactivation of bacteria, so anything shown to overcome this challenge will be highly valued
Solution must either cause cementation of material or modify the viscosity in some way to improve handleability
This organization is open to hearing non-biological approaches, but the primary focus is on biological approaches
Any approaches that reduce presence of harmful contaminants may also be of interest

Possible Solution Areas

Bio-grout
Self-healing concrete
Soil improvement
Tailings stabilisation
Carbon sequestration
Bio chemical Acid Mine Drainage (AMD) mitigation
Bio-engineered bacteria
Bio-cementation

Desired Outcome of the Solution

Improved understanding of the landscape of biological approaches to solidify slurries
Understanding of the current state of the art of activation/termination mechanisms of bacteria
