Organics recycling

Organics recycling

We receive and process much of metropolitan Adelaide’s green organics through council kerbside and business collections, as well as food organics from hotels, supermarkets, schools, office buildings, food processors and manufacturers.

Landscape and garden supplies

We offer a range of popular Jeffries-manufactured compost, soil and mulch products. They are available at retail outlets across South Australia or provided directly to landscapers, civil contractors, schools, local government organisations and home gardeners. For larger jobs, bulk landscape products can often be spread with our unique PowerScaper service.

Horticultural products

We cater to vineyards, vegetable growers, orchards and turf management specialists with our range of Australian Standard and NASAA certified organic compost, soil, mulch and top-dressing products. Our knowledgeable team also arrange and supply custom blends.


The best recycled products on the market

Jeffries composts, soils and mulches are of the highest quality on the market. They are used in commercial projects, landscapes and growing applications, especially vineyards and vegetable growing, but are also used in home gardens (making tomatoes taste like real tomatoes all over Adelaide!).

Adding nutritional benefits to soil, increasing soil carbon, improving water retention and reducing water evaporation, using Jeffries products can help increase crop yields and grow healthier plants.

When you choose a Jeffries compost, soil and mulch, you are choosing the safest and cleanest recycled organic products on the market.

What goes into Jeffries products?

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.

Technology turning organics into a quality product

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.

Our Story

Over the Years


The Jeffries family arrived in Adelaide

John Jeffries, born in 1805, and his wife Susannah and young son Johnson arrived in Adelaide on the ship, City of Adelaide in 1842. He bought land at Gawler Plains and named the property Sturton. John and Susannah had 11 children.


Fred Jeffries was born

The farm was eventually divided between four of John’s sons including the youngest, Robert Nelson Jeffries. Robert and his wife Mary, who was under age at the time, eloped and had five children. The eldest, Frederick Nelson Jeffries, was born 15/5/1885.


Fred Jeffries marries 

Fred married Ethel Painter in 1912 and went on to have six children. Fred did not carry on with the family farm as by now there was not enough land to share. He was a hard worker and put his hand to many things including butchering and driving buses. 


First truck purchased

Fred eventually bought a truck and, carted manure from Balaklava and Mallala to some of the new nurseries starting up around Adelaide at that time. As it had to be shovelled on and off by hand, one load a day was all he could manage.


Expanded to soil deliveries

His eldest son, also Fred (born 6/2/1913), sourced and delivered soils to the home gardens of Adelaide and the emerging landscape trade. He married Delia Nordhausen on 10/8/1940 and had five children: 3 girls and 2 boys, including eldest sone Leonard Frederick Jeffries born 14/3/1946).


Quality loam began to run out

Eventually the local supply of quality loam used by Jeffries to blend their soils began to run out. With increased demand for their products, Jeffries needed to completely review the way they operated in order to move forward. Eldest son, and third generation Managing Director Len Jeffries recognised that the company’s survival lay in manufacturing material to meet the needs of their customers and suppliers.


First move into manufacturing

Eldest son, Len, and now third-generation Managing Director, recognised that the company’s survival lay in manufacturing material to meet the needs of their customers and suppliers.


Len has two sons

Len Jeffries has two sons, Lachlan Jeffries (born 1971) and Martin Jeffries (born 1974)

By the 1980s there was becoming a better understanding of the need for material that would both improve soils and assist plant growth.


Idea for compost and mulch

Len struck upon the idea of producing soil additives in the form of compost and mulches. 

Len and the Jeffries team wrote the instruction manual for commercial composting as they went along, heavily researching and drawing on worldwide information and experience to produce compost from recyclable material and green organics.


Sign agreements with councils

With the increasing volume of green organic material being produced by Adelaide’s gardeners and local councils, Jeffries signed agreements with local councils to ensure a regular supply of kerbside green organic material.


Relocated to Winfield

Jeffries expanded to larger premises to allow space for processing material and building composting windrows.


Lachlan Jeffries takes the helm

Lachlan and Martin Jeffries both have two children, Beau, Sky, Hugh and Aston. The future fifth generation Jeffries.


New generation of Jeffries are born

World-class facility created at Buckland Park

Further improvements have seen the expansion of Jeffries Group including the construction of a multimillion dollar, world class environmental recycling development located on a 125 hectare site at Buckland Park just north of Adelaide.


Martin Jeffries becomes Managing Director

In 2014, Martin Jeffries takes over from his brother as Managing Director of the Jeffries Group. 


150,000 tonnes of green organics recycled each year

The Jeffries Group which now employs more than 70 people and recycles over 150,000 tonnes of green organics each year, receiving the majority of kerbside-collected green organics from Adelaide metropolitan councils. The company supplies quality compost, soil and mulch products to landscape yards and leading vineyards and vegetable growers across South Australia.
