Putting carbon back into the soil, for generations…

About Jeffries

We have had our hands in South Australian soil for generations, growing strong since 1842. Driven by wholesome family values and innovation, we have developed world-leading organic recycling technologies including our BioChar plant. 

Jeffries BioChar

In 2021, we commissioned one of the largest biochar plants in the Southern Hemisphere. Fuelled by recycled woody green organics, our plant is designed to produce around 1500 dry tonnes of biochar each year.

Jeffries BioChar is a very stable form of carbon which is returned back into the soil, safely storing the carbon out of the atmosphere for hundreds of years.

Not only does the plant create high quality biochar, it also generates it’s own energy. 

We recycle organics

We compost over 150,000 tonnes of organic material from South Australian homes and businesses every year through our facilities in Northern Adelaide, saving them from being lost to landfill.

Turn them into compost

This organic material is composted and transformed into compost, soil, mulch & organic fertiliser, with oversized woody material turned into Jeffries BioChar. This is returned back into the soil by local farmers, viticulturalists, landscapers and home gardeners.

Produce our own power

Syngas produced by pyrolysis in the creation of Jeffries BioChar is used to power our operations including R.O.S.S, our state-of-the-art recycled organics screening system. Any unused power is exported to the grid.

Our focus to combat climate change

1. Reducing greenhouse gas emissions

  • Reducing methane production from landfill by recycling 150,000 tonnes of organic material means we are stopping 315,000 tonnes of CO2 – e from being produced.

2. Improving South Australian soils

  • Recycled organics are composted and transformed into compost, soil, mulch, organic fertiliser and biochar.
  • Jeffries has been supporting South Australian farmers, viticulturalists and gardeners to improve their soil and quality of harvest for generations.

3. Utilising renewable energy

  • Fueled by recycled woody green organics, 100% of syngas produced from our biochar plant is used in specialised oxidisers to produce waste heat to run Organic Rankine Cycle (ORC) turbines and supply more than enough power to run our state-of-the-art ROSS compost screening plant. Any unused power is exported to the grid.
