Compost Products

Supporting our customers on their way to a more sustainable future, we offer two types of compost products: super compost and premium compost.

The Notion of Compost

What is Compost?

Compost is the product resulting from the controlled biological decomposition of organic material that has been sanitised through the generation of heat and stabilised to the point that it is beneficial to plant growth. Compost bears little physical resemblance to the raw material from which it originated.

Compost is an organic matter resource that has the unique ability to improve the chemical, physical, and biological characteristics of soils or growing media. It contains plant nutrients but is typically not characterised as a fertiliser.

We provide two types of multi-purpose organic compost; Super and premium. These composts have been processed under controlled conditions to produce a high quality product.

Super compost is a natural product made by mixing, stacking and turning biodegradable materials under managed conditions. The compost sold by A+E has been made wholly from plant materials recycled from parks, gardens and households.

Premium compost is a natural product made by mixing, stacking and aerating biodegradable materials under strictly controlled conditions in an in-vessel composting system with a separate maturation phase. The compost sold A+E has been made from a mixture of food waste from our commercial food waste collections, along with plant materials and organic waste recycled from parks, gardens and households.

The Production of Compost

How Compost is produced?

Compost is produced through the activity of aerobic (oxygen- requiring) microorganisms. These microbes require oxygen, moisture, and food in order to grow and multiply. When these factors are maintained at optimal levels, the natural decomposition process is greatly accelerated. The microbes generate heat, water vapour, and carbon dioxide as they transform raw materials into a stable soil conditioner. Active composting is typically characterised by a high-temperature phase that sanitises the product and allows a high rate of decomposition, followed by a lower-temperature phase that allows the product to stabilise while still decomposing at a lower rate. Compost can be produced from many “feedstocks” (the raw organic materials, such as leaves, manures or food scraps). State and federal regulations exist to ensure that only safe and environmentally beneficial composts are marketed.

The Production Method of Compost

Compost In-Vessel

It is an accelerated version of the natural composting process where biodegradable waste is fed into large, enclosed chambers with added heat, carefully controlled pH and microbial action to create premium-grade compost in three days. Take a look at the individual steps above. 

We also use open windrow composting to recycle purely garden waste. The material is shredded and formed into trapezium shaped piles and then monitored for moisture and turned to aerate over eight weeks. This produces a quality compost which is screened and sold to the agricultural or horticultural industry.

Physical Benefits of Using Compost

Improved Structure

Compost can greatly enhance the physical structure of soil. In fine-textured (clay, clay loam) soils, the addition of compost will reduce bulk density, improve friability (workability) and porosity, and increase its gas and water permeability, thus reducing erosion. When used in sufficient quantities, the addition of compost has both an immediate and long-term positive impact on soil structure. It resists compaction in fine- textured soils and increases water holding capacity and improves soil aggregation in coarse-textured (sandy) soils. The soil-binding properties of compost are due to its humus content. Humus is a stable residue resulting from a high degree of organic matter decomposition. The constituents of the humus act as a soil ‘glue,’ holding soil particles together, making them more resistant to erosion and improving the soil’s ability to hold moisture.

Moisture Management

The addition of compost may provide greater drought resistance and more efficient water utilisation. Therefore, the frequency and intensity of irrigation may be reduced. Recent research also suggests that the addition of compost in sandy soils can facilitate moisture dispersion by allowing water to more readily move laterally from its point of application.

Chemical Benefits of Using Compost

Provides Nutrients

Compost products contain a considerable variety of macro and micronutrients. Although often seen as a good source of nitrogen, phosphorous, and potassium, compost also contains micronutrients essential for plant growth. Since compost contains relatively stable sources of organic matter, these nutrients are supplied in a slow-release form. On a pound-by- pound basis, large quantities of nutrients are not typically found in compost in comparison to most commercial fertilisers. However, compost is usually applied at much greater rates; therefore, it can have a significant cumulative effect on nutrient availability. The addition of compost can affect both fertiliser and pH adjustment (lime/sulfur addition). Compost not only provides some nutrition, but often makes current fertiliser programs more effective.

Modifies and Stabilises pH

The addition of compost to soil may modify the pH of the final mix. Depending on the pH of the compost and of the native soil, compost addition may raise or lower the soil/compost blend’s pH. Therefore, the addition of a neutral to slightly alkaline compost to an acidic soil will increase soil pH if added in appropriate quantities. In specific conditions, compost has been found to affect soil pH even when applied at quantities as low as 10-20 tons per acre. The incorporation of compost also has the ability to buffer or stabilise soil pH, whereby it will more effectively resist pH change.

Biological Benefits of Using Compost

Provides Soil Biota

The activity of soil organisms is essential in productive soils and for healthy plants. Their activity is largely based on the presence of organic matter. Soil microorganisms include bacteria, protozoa, actinomycetes, and fungi. They are not only found within compost, but proliferate within soil media. Microorganisms play an important role in organic matter decomposition which, in turn, leads to humus formation and nutrient availability. Microorganisms can also promote root activity as specific fungi work symbiotically with plant roots, assisting them in the extraction of nutrients from soils. Sufficient levels of organic matter also encourage the growth of earthworms, which through tunnelling, increase water infiltration and aeration.

Suppresses Plant Diseases

Disease incidence on many plants may be influenced by the level and type of organic matter and microorganisms present in soils. Research has shown that an increased population of certain microorganisms may suppress specific plant diseases such as pithier and fusarium as well as nematodes. Efforts are being made to optimise the composting process in order to increase the population of these beneficial microbes.
