The City of Port Adelaide Enfield and APR Composites have together completed a major environmental project along the Semaphore foreshore, installing an 883-meter-long retention wall made from recycled materials to protect the coastline from erosion.
The project uses over 105,000 kilograms of reclaimed timber and recycled plastic, which is equivalent to more than one million two-litre plastic milk bottles. It has diverted around 3,680 cubic meters of plastic from landfills – a significant achievement in waste reduction and sustainability.
Designed and manufactured entirely in South Australia, the new retention wall is chemical-free, low maintenance, and durable. Unlike traditional wood or steel options, it features no sharp edges or splinters, making it safer and user-friendly. The new structure replaces an old fence that was damaged by a storm a few years ago.
Local business APR Composites played an important role in the project by repurposing local waste materials into high-quality products, such as boardwalks and bollards. With over one million kilograms of plastic repurposed annually, APR Composites is a leader in the circular economy, demonstrating how recycled materials can benefit both the environment and the community.
“Our work with the City of Port Adelaide Enfield is a testament to what can be achieved when local governments and businesses collaborate towards a sustainable future,” says Ryan Lokan, CEO of APR Composites.
“We are proud to play a critical role in the circular economy, showcasing how recycled materials can be effectively utilised to both preserve our environment and enhance our community.
“We’ve had the pleasure of working on some incredible local projects such as the Grange Jetty, Hallett Cove and Arno Bay Mangrove Boardwalks and other significant projects across the nation.
“But our current challenge is getting key decision makers and stakeholders to consider the more sustainable option when it comes to infrastructure projects within local communities.”
“This Semaphore Project is a prime example of how all parties involved have worked seamlessly to reimagine the lifecycle of recyclable materials to create products that not only benefit our community, but the planet in the long run,” says a CAWRA (Central Adelaide Waste and Recycling Authority) spokesperson.
“This project not only marks a significant advancement in managing coastal erosion but also sets a benchmark for future projects that aim to combine ecological preservation with community development.”
