Western Composting Technology (WCT) – specialists in alternative waste treatment

We have the expertise and agility to build, own or operate alternative waste treatment facilities in Australia. Our waste treatment technologies include in-vessel (tunnel), windrow and aerated static pile composting, and anaerobic digestion (wet and dry).

Our Shepparton success story - bringing tunnel composting to the communities of northern Victoria

In 2005, Greater Shepparton City Council awarded WCT the contract to process 8,000 tonnes annually of municipal source-separated kerbside garden waste.

We completed construction of our flagship Shepparton tunnel composting plant in October 2008. Our facility can receive and process:

  • green wastes
  • municipal food organics and garden organics
  • solid commercial food and food processing wastes including fruit and vegetable products (from SPC and Campbell Soups), solid milk residue, scallop shells, food retail (out of date and damaged food) and post-consumption (leftover food waste generated from restaurants).

We have since expanded our reach via long-term contracts to receive waste from surrounding areas including councils in Moira, Benalla, Strathbogie and Wangaratta, and local retail and commercial businesses. More recently, WCT was awarded contracts by Surf Coast Shire Council and Borough of Queenscliffe to accept and process approximately 3,500 tonnes of green waste per year. The contract commenced in August 2017.

Why choose alternative waste treatment technologies (such as tunnel composting)?

When done well, they are better for the environment and more cost-effective for the community. They use a natural process to recycle organic materials and free-up landfill space.

The collection and transportation of mixed source-separated kerbside organic waste (including bin, kitchen caddy and compostable bags) and processing at a best practice alternative waste treatment facility costs approximately $1.90 per household per week in a regional municipality with 22,000 households.

Best practice management of organic waste is not “beyond the budget”. The reality is this: tunnel composting costs only $0.15 to $0.20 more per household per week than windrow or aerated static pile composting technologies. When you understand the biosecurity and environmental risks involved in composting wastes, it’s a small price to pay for risk mitigation.

The key is having an experienced specialist partner on board to provide the facilities and expertise, manage the processes and market the end-product.

How can you help

What goes in makes all the difference

Feedstock is the raw material that goes into the composting process. Feedstock contamination can seriously affect how our processing plant functions and the quality of our end products.

Tunnel composting is an environmentally sound way to recycle organic materials that significantly reduces waste stream volume and offers economic advantages for communities.

You and your community play a crucial role in the success of our composting program. When you eliminate contaminants (household hazardous wastes, plastic, glass) from composting feedstock (food scraps, grass, branches, leaves), you help make us more efficient, and our high-quality end product more consistent. You help us deliver more benefits back to your community.

At WCT, we’ve been working to educate you and your community about feedstock contamination and we’re already seeing results. You can keep helping us by staying informed and helping educate those around you.

Why tunnel composting technology?

Tunnel composting technology lets us carefully control environmental conditions during the composting process to produce minimal odours and little or no leachate (water draining off).

We enclose the feedstock in tunnels that operate in a batch mode. Because we monitor and control the process, including air supply, moisture and pH levels, we can generate rapid composting and produce consistently high-quality end product. Oxygen sensors in the tunnels tell us when and where air supply is needed and other systems help us capture exhaust gases for odour control and treatment.

With retention times ranging from one to four weeks, we can recycle more organic materials, in less time, in a smaller space and using fewer resources than other methods.

This technology allows us tighter controls on product quality and the ability to produce products that are weed-free and to higher standards than simple windrow technology.


High-quality compost you can rely on

WCT consistently produces high-quality compost and mulch products (GV10 and GV40) that meet the Australian standard 4454-2012 for composts, mulches, soil conditioners and related products.

Our products are consistent, safe, and reliable and marketable because we’re stringent about using feedstock that’s relatively free of inorganic materials and potential chemical and heavy metal contaminants. GV Compost is devoid of weed seeds and organisms that may be pathogenic to humans, animals, or plants, is relatively stable and is resistant to further rapid decomposition by microorganisms.

Safe, reliable, high quality and enviro-friendly – our products tick all the boxes.
