Cutting costs and closing the loop in construction

Sunshine Coast–based Rowcon is reshaping how governments and the construction industry manage and reuse waste material. As demand grows for projects that minimise waste and incorporate recycled materials, Rowcon has become a key supplier by helping industry reduce costs, minimise landfill, and support more circular construction practices.

What Rowcon does

Rowcon accepts and processes construction and demolition (C&D), green and commercial waste—from concrete and timber to metals and soil. These materials are transformed into high quality recycled products such as aggregates, roadbase, engineered fill, crusher dust, mulch and soils.

Their Corbould Park facility at Caloundra has capacity to process a tonne of waste per minute, and produces up to 350,000 tonnes of recycled material each year. That’s the equivalent of around 80–90 Olympic size pools of material which is recycled annually.

Origins of the business

Founded in 2017 by Benn Rowley, the business was built in response to the Sunshine Coast’s growing pipeline of civil and infrastructure projects. Rowley saw the opportunity early:

“I’d worked in C&D recycling for 20 years. After observing the pipeline of civil work planned for the Coast, I knew there was an opportunity for projects to save costs and divert waste from landfill. It didn’t take long before major government and private projects were partnering with Rowcon for their waste disposal solutions. We then built on these relationships, giving our clients confidence in compliant recycled concrete products, and started supplying quality recycled materials back into their projects.”

The financial advantage

Rowcon’s model offers a major financial advantage for their customers. Most mixed C&D waste sent to landfill attracts premium gate fees and levies. By processing this material locally, and resupplying it as specification ready product, Rowcon helps contractors avoid high disposal costs while purchasing recycled materials at more competitive rates than virgin equivalents.

A key driver for customers is source separation of C&D waste. This has a significant impact for sustainability, but it’s also commercially beneficial in terms of reducing disposal charges. With tip-and-reload options close to project sites, transport distances and costs are also reduced, this lowers the total cost of delivery and provides clear evidence for waste diversion and recycled content reporting.

Customer Service & Sales Manager Matt Gigney highlights the significance of these savings:

“Competitive disposal costs have been key. Disposing of clean concrete at our facility is significantly cheaper, usually offering savings of up to 80% of disposal rates at alternative locations. Using recovered material also means we’re not paying to source or process virgin materials, so we can pass those savings directly to customers.”

Growing demand and industry momentum

Demand for Rowcon’s products is rising as governments and industry look for delivery methods that reduce waste, improve efficiency and incorporate recycled content. Councils, state agencies and tiered contractors are increasingly specifying recycled options where performance is proven.

Rowcon’s consistent grading and local footprint have made their products a preferred choice for subdivisions, roads, utilities, car parks and commercial builds, especially where projects aim to reduce embodied emissions by prioritising recycled materials over virgin inputs.

Council projects

Moffat Beach Seawall Reconstruction Project - Recycling in action

Recognisable blue Rowcon skip bins could be found on‑site at the Moffat Beach seawall reconstruction project. These bins played a big role in helping Council manage construction waste responsibly. By using specialised skips, crews were able to sort and recycle materials directly at the site. This meant far less waste heading to landfill and significantly reduced disposal costs for Council – a win for both the environment and the community.

Not only did this approach save ratepayer dollars, but it also eased pressure on natural resources by reducing the need for new, or “virgin,” materials. It’s one of the many ways Council is working to deliver essential infrastructure while keeping sustainability front and centre.

Council landfill roads and hardstand

The need for low-cost recycled products is important to council as the organisation strives to reduce waste and emissions. Council sourced over 6,000 tonnes of recycled concrete aggregate from Rowcon for roads and hardstand at local landfill sites.

Rowcon was contracted to supply when council’s own stock of recycled concrete ran low. Rather than sourcing virgin materials, council sourced from the local supplier who could provide a low-cost recycled option.

Why it matters

According to Gigney:

“More customers are looking for ways to do business that are less resource and emissions intensive. That’s where we step in—we work directly with government and contractor clients to develop solutions that deliver better outcomes economically and environmentally.

I encourage businesses to look at how they can deliver goods and services that help buyers achieve their sustainability goals while remaining cost competitive.”

Rowcon offers a simple proposition: pay less to tip, pay less to buy, and keep valuable materials circulating for longer. For councils and major buyers, Rowcon strengthens the regional supply chain needed to deliver projects efficiently, cost effectively, and with reduced material and emissions impacts.

Aligning with procurement priorities

From federal down to local, governments and private industry are placing stronger priority on sustainability in procurement practices. Businesses that prove to align with buyer ambition in this space can improve supplier competitiveness. 

With a large pipeline of work taking place on the Sunshine Coast leading up to Brisbane 2032, local businesses have a great opportunity to build capability and join government and private industry supply chains.
