What it means to be certified compostable

6 Jan, 2020

Compostable defines a product that is capable of decomposing into natural elements, leaving no toxicity in the soil. If a material is considered compostable, controlled composting process should transform it into organic matter within 3 months, while under normal conditions this takes 1 to 2 years.

Australian standards compostable certification determines the compostability of a product and the effect it has on the quality of the resulting compost.

Every product, even if made of the same materials, have quite different chemical, physical and biological properties consequently performing differently in a soil.

At Jeffries, we currently prefer to accept compostable products that are certified to  Australian Commercial Composting Standard AS 4736 and/or Certified Home Compostable AS 5810. Look out for the below symbols on your compostable products.


The Australian Standard means that your product will break down into compost material with no toxic effect of the compost on plants and earthworms.

Producing safe, high quality compost for renewing our soils is one of our environmental pillars.  We require compostable packaging to meet the Australian Standard so that we and you know that our composts, fertilisers and mulches are safe to use even for organic farming, food production, in public spaces and in your home garden.  

Other standards including from the European Union do not meet this toxicity test and so we cannot take them in our compost.

How compost reduces irrigation requirements and conserves water

How compost reduces irrigation requirements and conserves water

One major advantage of compost is its ability to hold moisture, retain it for longer, increase the amount of water available to plant roots, and minimise the need for irrigation. Ultimately, improving water saving practices and reducing economic overheads for farmers. But how exactly does it do this?

If we dig deeper, we find that compost helps to save on water in a few different ways.
