Soil for generations

At 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 and collection partnerships.

Combining our passion and process the team at Jeffries delivers premium compost, soil and mulch for farmers, viticulturists, landscapers and home gardeners. Together, we are securing the future of healthy soil for generations to come.

Organics recycling Collection

The green organics received at Jeffries are from most of metropolitan Adelaide’s council kerbside collections. In addition, organics collections from supermarkets, hotels, restaurants and food processors are a rapidly growing market, with commercial enterprises seeking a green alternative to the disposal of their organic waste.
Large quantities of tree trimmings, street sweepings and end-of-life wooden pallets make up much of our clean green and clean timber inputs. We also accept liquid organics from various sources including grease traps, stormwater, wineries and food processors.



We pride ourselves on having an innovative approach to processing organics.
We start by sorting our raw materials – garden trimmings, food scraps, tree prunings, liquid organics, wood chips – pretty much anything that once grew.
We then compost the organic material using our customised aeration system for six to eight weeks. Once matured, the sweet smelling compost is sorted through our state of the art Recycled Organics Sorting System (ROSS). This is where the majority of inorganic pieces that have historically been a major problem for compost processors are removed using innovative, mechanical, technological and manual sorting techniques.
