Before you understand the environmental benefits of soil transfer and soil reuse, you have to know what it is and why civil works, construction and mining companies are starting to use it at the end of their projects.

Defining soil reuse

The concept behind soil reuse is very simple and straightforward. At the end of a construction or civil works project, you may find that you have a lot of soil and scraps or debris leftover. Normally, these leftovers get wasted or simply left at the project site. While this may not necessarily change the surround environment's composition, you're essentially wasting a valuable resource.


Instead, you could perform a soil transfer and reuse the leftover soil or debris for other projects or uses. For example, you could take the leftover soil from a trenching project and use it in a potholing project.


You could also use it to fill in any gaps or holes in your next project without having to worry about digging into the land more and disrupting the natural flow of the landscape. If you have scraps like timber, rocks or concrete and brick, you can recycle it and cut your cleanup costs by transporting it to a recycling centre and letting them handle it.

There are several environmental benefits that come with soil reuse - this is why both large and small companies are starting to incorporate it into their project practices. 


A few key environmental benefits include: 

1. Reduced Greenhouse Gas Emissions

A popular way to perform soil transfer is by performing non-destructive digging and transporting a slurry of waste away from the project site in a sucker truck. Since you can compact a lot of the slurry, there are fewer and smaller sucker trucks taking the waste away. This is healthier for the environment, and it reduces greenhouse gas emissions, too.        


2. Reduced Damage to the Surrounding Environment

To get the most out of soil transfer projects, companies continue to turn to non-destructive digging. This form of digging uses pressurised water to break up the soil and suck it into a holding tank. It allows you to get precision results without tearing up large portions of the soil or leaving a large mess upon project completion.


3. Reduced CO2 Emissions

Since you can compact the waste into the holding tanks, there are usually fewer vehicles travelling to and from your Brisbane project site. In turn, there are fewer CO2 emissions released into the surrounding environment. It also helps to keep the roadways clear for other vehicles and traffic because there are fewer large vehicles travelling to recycling centres.


4. Reduced Debris Left at the Project Site 

There can be a lot of miscellaneous debris left at the end of the project, and this debris can pollute the surrounding environment, more or less severe depending on the type of debris. By performing soil reuse, you remove anything that is left over and either recycle it to use again or take it to the appropriate centre and have them dispose of it for you.
