What is Biochar?
Biochar is a form of charcoal produced from sustainable sources in an energy efficient way and used for any purpose that does not result in the immediate release of carbon back into the atmosphere.
The biochar is produced from biomass by a process called pyrolysis. The biomass is heated to very high temperatures in the absence of oxygen leading to the formation of carbon residues or charcoal.
When biochar is applied to the soil it can last for thousands of years, acting as a stable carbon store capturing carbon from the atmosphere and locking it in a solid form. It also has received a lot of attention due to its potential ability to increase plant growth and ultimately crop yield.
What are it's Benefits?
Biochar has a multitude of applications from being used to enhance plant growth to the treatment of slurry and sequestering carbon. Developing biochar’s use across the world will aid in the development of a sustainable carbon economy, benefitting not only individual clients but also the world.
Recently, Earth Systems and Territory Natural Resource Management conducted biochar soil trials at an organic farm in Northern. The biochar was produced and supplied by Earth Systems’ CharMaker MPP20 using waste wood as the feedstock. Key results of the trials include a 25% crop yield increase in one of the zucchini plots, increased pH, soil carbon and available water capacity.

Other Products of the Pyrolysis Process
The pyrolysis process causes organic compounds to volatise and in traditional charcoal production these are released into the atmosphere or incinerated. However with technology and expertise at Earth Systems we are able to capture these gases and condense them to form a number of different bio liquids which have agricultural and power generating applications.
