How do you actually create a system that functions, especially when the most fundamental resource – topsoil - is limited?

Across Australia, one of the most persistent challenges in mine closure is the availability and quality of topsoil. Even where topsoil exists, volumes are often insufficient, variability is high, and storage can degrade its biological and structural integrity rapidly.

The result? Rehabilitation strategies that rely on topsoil alone are increasingly constrained - and in many cases, fundamentally misaligned with the scale of the challenge. But there are solutions.
