Our proven capabilities

Over the last 30 years we have worked on many major projects, both locally and internationally to expose the value of land and groundwater. We have successfully assisted in the remediation of land, creating a cleaner, greener earth for future generations.


When land needs to be nurtured, repaired, sustainably utilised or its value unlocked, our name should be foremost in mind. We are committed to producing scientifically sound work that offers our clients the best value.

To understand how this is going to impact the cost of your project you need to understand what areas of Queensland the levy a...

Bioremediation Processes at Soil Recycling Facility

  Bioremediation is a process in which the natural microbes in the soil are promoted to digest hydrocarbon based contaminants. Contaminants that fall into this category include polycyclic aromatic hydrocarbons (PAHs), such as those produced as a waste by-product in gas manufacture, and petroleum hydrocarbons (TPHs), such as those typically found at service stations (including petrol, diesel and oils). The bioremediation of these materials does not necessarily occur in-situ. This is wh...
