Finlay: woodchips to energy

Veolia’s recent moves in the waste-to-energy market has seen them team up with specialist equipment supplier Finlay.

Populations are growing and, as a result, so too is waste generation. Conversely, landfill capacity is declining as urban areas become increasingly dense.

While the waste hierarchy privileges avoidance, reuse and recycling, interest in waste-to-energy as a solution for material that falls through the cracks is growing. Capturing this potential was the driving force behind Veolia’s decision to open a new facility in Horsley Park, New South Wales.

According to site manager Stephen Bernhart, the new resource recovery facility handles wood waste material, which it then processes into a wood chip product.

“After running multiple equipment trials in 2018, we have recently kicked into operation,” Stephen says.

He adds that the wood chip product will be provided to a customer where it will be used as a substitute for coal within a cement kiln.

Veolia’s facility processes a significant amount of wood waste, such as pallets, offcuts and plywood which need to be shredded, and has the capacity to receive 430,000 tonnes of general solid non-putrescible waste per year.

“We have detailed specifications we need to meet to supply our waste-to-energy customer, and a big part of that is ensuring we achieved a material size sub 50 millimetres,” he says.

“It’s quite a challenging task because it’s such a small grade, so we decided to invite multiple suppliers out to the site to run tests and demonstrate their equipment.”

Stephen says Finlay Screening, Crushing and Recycling Systems, a supplier of screening and processing equipment for the waste and recycling industry, stood out during the trials.

“Finlay were heads and shoulders above the rest in demonstrating not just what their equipment could achieve, but how it could achieve it consistently,” he explains.   

Finlay initially trialed a medium speed shredder, however, the resulting material didn’t quite meet specifications. Three weeks later they were back, with a Terex Finlay 693+ Super Track Screening Plant that, according to Stephen, worked extremely well.

“During the second trial there was a large lump of steel which had passed through the primary shredder into the secondary shredder,” Stephen says.

“The TDSV20 shredder shut down as intended, and Finlay representatives opened it up to remove the steel. The machine was back up and running in approximately three minutes – I was very impressed with how the equipment handled it.”

According to Stephen, Finlay also demonstrated how the shredding equipment could maintain the required tonnage throughput in spite of the small material specifications.

In addition to the screening plant, Stephen purchased a Terex Finlay TDS 820 Slow Speed Shredder and a Terex Finlay TDS V20 Mid Speed Shredder and Finlay 5032HD wheeled conveyor.

Built to process bulky, solid waste, the TDS 820 has a two-metre shaft manufactured with a fully welded tooth configuration. Stephen explains that the length allows for significant throughput and size reduction of material.

“The machine’s independent gearboxes enable each shaft to be run separately, which reduces material wrappage and facilitates viable shredding,” he adds.

The Terex Mid Speed Shredder has a twin-shaft, allowing it to perform both primary and secondary shredding. The TDS V20 also has the ability to self-protect against uncrushable material like steel, making it well suited to shredding waste wood materials.

“We have had no trouble meeting specifications after procuring the equipment, all three machines have been running very well.”

According to Stephen, there has been very little down time at the Horsley Park facility.

“There were one or two minor teething issues initially, but Finlay were able to handle them quickly and without fuss,” he says.

Finlay representatives also assisted on-site equipment training when the facility was commissioned.

“They are very forthcoming with their information and we were able to get local contractors trained up on how to run and maintain the shredders and screening plant as well,” he says.

“We are at a really exciting stage in our capability with an eye for expansion, so it’s crucial to have equipment that’s both reliable and efficient.”

Finlay: separating the grime

Phoenix Environment Group is sorting problematic C&D waste from all over Melbourne into saleable streams, with the assistance of Finlay Screening, Crushing and Recycling Systems.

Mixed waste from construction and demolition sites is regularly left out in the rain or intense heat for long periods of time by some contractors and site managers. As a result, construction and demolition waste (C&D) often arrives at processing and recycling facilities as a wet, sticky mass, loaded with heavy and bulky debris.

Phoenix Environment Group, a recycling company based in Melbourne’s northern suburbs, receives waste from all over the city and deals primarily in C&D. Phoenix operates largely as a sorting facility, separating C&D into seven different streams before sending it to alternate facilities for remanufacturing.    

Company Director Ash Walker says given the nature of C&D, the material Phoenix receives is often quite contaminated, with multiple mixed materials needing to be screened and separated simultaneously.

To facilitate the cleaning of grimy material, Phoenix purchased a Terex TRS 500 from specialist equipment suppliers Finlay Screening, Crushing and Recycling Systems last year.

“We needed a recycling screen capable of separating heavy weight material from recyclable waste before we send it to separate picking stations for further separation,” Ash says.

“Our previous screen worked well. However, as the company grew and began to work with larger, more commercial clients, we required a new recycling screen to keep up with processing demands.”

The TRS 500 recycling screen is a versatile mobile screen that operates with a specialist screen box designed by German manufacturer Spaleck.

Ash says he spent a number of months researching recycling screens online before coming across the TRS 500.

After contacting Finlay about the machine, Ash was flown to Queensland to view the screen in operation.

“Once I had watched the TRS 500 in action at Finlay’s facility in Burpengary, I became confident in its ability to fulfil Phoenix’s business requirements,” Ash says.

“The Terex machine is much bigger than our previous screen, so we are able to put significantly more material through each hour – it ticked all the boxes for me.”

Phoenix has been using the TRS 500 for just under 12 months, and Ash says it hasn’t missed a beat.

“We use the screen to reclaim a lot of mixed soil and it works 100 per cent of the time,” Ash says.

“Every inch of soil is screened and cleaned effectively and quickly, which means we can remove all the contaminants at a cheap price.”

According to Ash, the machine was specifically designed for difficult applications, with the combination of a three-way split system and Spaleck 3D Combi screen box allowing operators to process material previously classed as problematic.

Phoenix uses the TRS 500 to process a minimum of 2000 tonnes of C&D waste at its Coolaroo recycling centre each month.

“Most of our material comes from Campbellfield Bins, Ben’s Bins Hire, Cleanaway and a handful of smaller waste removal companies,” Ash says.

Spaleck screen boxes are designed for efficient screening of wet inhomogeneous material, with separation cuts between 0.2 and 50 millimetres.

The TRS 500 incorporates the Spaleck screen box into a standard Terex platform and frame, with features including a steel apron feeder for feeding heavy bulk material, a 3D top deck screening panel and an aggressive flip-flow bottom deck.

The base frame is agitated by a shaft and unbalanced motor drive, with the vibration passed to the frame via thrust rubbers.

Ash says the tracked heavy duty screen can be operated in a wide range of primary and secondary screening applications.

“The 3D flip flow bottom deck mats can handle high-moisture material, even when screening as small as two millimetres without blinding,” Ash says.

“This ability is critical given the nature of the material we’re processing, as it reduces downtime and maximises our production capabilities.”

Additionally, Ash says the TRS’s 3D screening segments facilitate correct grain size and eliminate long and extraneous material for the tension shaft screen on the lower deck.

“The screwless mounted screening mats create less contamination than regular mats and the high acceleration has a self-cleaning effect,” he says.

Ash says Finlay has a services and parts division in Melbourne, meaning it is just around the corner when the machine needs servicing.

“They respond straight away when I make a booking and are always on call. I’ve been really happy with the service,” Ash says.
