Recycled plastic conveys a strong message

Recycled plastic

DYNA conveyor guarding is made out of recycled plastic as an environmentally friendly, sustainable alternative to steel guarding.

DYNA Engineering’s high-density polyethylene plastic conveyor guards are not only helping to reduce risks on-site, but also helping the environment, as they are made from recycled plastic bottles that would otherwise be sitting in landfill.

Materials handling is one of the most crucial parts of the mining process and doing it safely and efficiently is an art that DYNA Engineering has perfected.

DYNA Engineering’s range of high- density polyethylene (HDPE) plastic conveyor guards provides all the benefits of the older steel alternatives, but in a more robust, lighter and sustainable package.

Steel guarding has been used in the industry for decades, and there have always been issues with safety and longevity with these products, including corrosion and rust, resulting in some hefty maintenance costs.

DYNA Engineering general manager Thomas Greaves said the company saw a niche in the market to design and make conveyor guarding out of recycled plastic as an environmentally friendly, sustainable alternative to steel guarding with all the other benefits tied in with it.

“While DYNA has competitors in the market, no one else is using recycled plastic for the guarding like DYNA is,” he said.

“We’ve got that sustainability focus by trying, as much as possible, to use recycled material. We have used large volumes and get a really good life out of it.

“A lot of the plastic that we’re using is commonly used to make plastic drink bottles, milk bottles and juice bottles. That sort of plastic only has a month or two of life and then it gets thrown away.

“So having a product that uses a really large volume of that, and for such a long period of time, 10+ years, is a real benefit of our product over our competitors.”

The HDPE guarding meets all the Australian standards, but a major difference between it and steel guarding is that HDPE is a robust and flexible material.

One issue that often arises on-site is when steel guarding gets hit by rocks or gets bent, it generally has to be cut out to do maintenance and it doesn’t fit back in properly, or it has sharp edges and bits of wire sticking out.

“HDPE solves quite a few of those issues because if the guard gets impacted it flexes back into shape rather than being permanently damaged,” Greaves said.

DYNA Engineering’s lightweight HDPE guarding allows workers
to easily put it back in place following a shutdown.

Whilst having a standard design that’s applied to every application, DYNA operates under the statement ‘no conveyor is identical.’

“When we do guarding, we go on- site, we measure, we design and we supply the guards for that particular application,” Greaves said.

“Because you have to guard around the conveying equipment, the monitoring equipment, and all that sort of stuff as well. You can’t just get one design and slap it on everything. It just doesn’t work that way. Every conveyor is different. So, even using our base design it still needs to be made for each application to make it work properly.”

HDPE is corrosion-resistant and immune to rust and is the common choice when it comes to working in high-corrosive mining environments.

“We’ve done jobs for iron ore, coal, gold, copper, nickel, a lot of different sites. But we’ve had the most interest from those who are operating in a corrosive environment or are using corrosive chemicals,” Greaves said.

“Since we released our product, we’ve seen increased interest and implementation of HDPE guards on-site and we don’t see that slowing down. We get more and more inquiries from different companies each day.”
