Trend: Recycling Safety vests into New Concrete Materials in Australia

A Creative and Sustainable Concrete Material Innovation Made from Recycled High-Visibility Vests in Australia

A laboratory in Melbourne, Australia has recently announced a promising invention of recycling old high-visibility vests into a new concrete material. This breakthrough is a significant step toward reducing plastic waste and protecting the environment in the country!

Why Create Concrete from Safety Vests?

Firstly, Reflective Safety Vests Are Often Made from Polyester Fibers and Enhanced with Flame Retardant Materials or High-Temperature Resistant Fibers like Aramid and Nomex, Which Are Slow to Ignite and Burn.

Based on this, a laboratory research team in Melbourne has successfully extracted these types of fibers to create a foundation for fire-resistant concrete materials with a high-density, strong bonding structure.

Furthermore, Associate Professor Malindu Sandanayake from Victoria University, who leads the project, highlighted that many safety vests are discarded as waste — approximately 11,000 tons every year. These vests are typically used for short-term construction projects, with an average of 25 washes before they are deemed unusable. As a result, damaged safety vests are often thrown into landfills, contributing to environmental pollution risks.

Because of this, Associate Professor Malindu Sandanayake and his team discovered an innovative solution by finding an alternative material to replace cement in concrete.

Effectiveness of Concrete Made from Safety Vests

Expected Results:

• Concrete with higher durability and better load-bearing capacity.
• Reduction in plastic waste.
• Creation of a sustainable construction material.

Actual Results:

These types of concrete have already been applied in the grounds of the Mahamevnawa Buddhist Monastery and in a material storage facility at a construction site in Melbourne.

According to the researcher:

"The results show that the target strength we aimed for was achieved earlier than expected, which is really good. It is almost on par with the traditional concrete mix we designed, and it demonstrates superior durability. In terms of fire testing, it performs exceptionally well. Therefore, we believe that the presence of these fibers enhances the fire-resistant properties within the concrete slab. This could potentially be a great fire-resistant concrete material for future use."
