Shredding a Path to Better Recycling
Tutt Bryant shredding a path to better recycling with M&J Recycling. M&J Recycling shredders are known for its heavy-duty strength and play an important role in Australia’s transition towards a circular economy.
Efficient waste processing can reduce the reliance on landfill and lead to better recycling. Wires, a metal grille, even a discarded cabinet cling together as a load for crane claw hovers over churning saw teeth. It releases its grip and waste clatters into the feedlot and disappears. What appears on the conveyor belt below is barely recognisable.
Tutt Bryant Equipment is one the largest national multi-franchise distributor of earthmoving and construction equipment, consumables, parts, and services, as well as used equipment. Tutt Bryant industries coverage include recycling, demolition, construction, government, general equipment hire, infrastructure and mining. Since 2019, Tutt Bryant Equipment has been the exclusive national distributor of M&J Recycling Mobile Shredding Equipment.
M&J Recycling takes its name from the two founding fathers, Moeller and Jochumsen, who began making steam engines in Denmark, in 1857. With the industrialisation in Europe, they moved to manufacturing diesel engines and evolved into waste shredders in 1988, as one of the leaders of Denmark’s ‘green transformation’, which focused on turning waste into resources.
Now with more than 1000 installations worldwide, and with a continued focus on research and development, M&J is a leading supplier of industrial waste shredders for the recycling industry.
Paul Doran, Tutt Bryant Equipment National Business Manager, Crushing and Screening, says M&J Recycling’s success lies in understanding customer requirements and a respect for individual preferences.
“M&J Recycling knows from experience that co-operation with customers, partners, and suppliers – based on mutual respect and trust – leads to the best results,” he says.
M&J Recycling pre-shredders and fine shredders have great features and a robust construction enabling them to tackle a range of waste materials – either in bales, rolls, bricks, or as loose material.
The pre-shredder is suitable for construction and demolition (C&D) waste that often contains everything from wood and plastic through to concrete and metals. The open-cutting table design minimises wear while ensuring high throughput.
Other features include shredding in both directions and online monitoring of performance and health status.
“The shredders have a double hydrostatic system, which means the shafts work independent of each other and cut in both directions, doubling shredding time in the hopper,” Paul says. “The open cutting table technology and welded-on-knives means that these shredders are not sensitive to stronger and tougher material. They also provide the highest possible availability factor, lowering production cost.”
The 35-tonne M&J 4000M has 8-12 knives per shaft to provide a range of product sizes, depending on the desired output. Paul says this is why its M&J’s most popular mobile model globally.
Why Shred?
The primary purpose of shredding waste is to reduce the incoming material to a more manageable particle size. For waste operators, this means fine materials comingled with bulky materials can be separated and used for other purposes, such as a day cover, rather than take up landfill space. The size reduction also increases the recovery rate through a picking station. Because the pieces are easier to manage by hand, there’s more recoverable such as wood, metals, and concrete, diverted from landfill.
Paul says the size reduction of material also improves payload density, making transport more cost-effective. Smaller material means more tonnes per truck load for the same cost, or less vehicle movements per day, lowering the carbon footprint of an operation.
Shredding waste to a smaller size and breaking hard materials also ensures landfill compaction is achieved with less effort, either by fewer passes of the compactor or by using a smaller compactor. Both will reduce site operational costs.
This density improvement, Paul says, extends the life of landfills in the current environment where new approvals are difficult and expensive to obtain.
He recalls and M&J 4000M owner/operator who confirmed that the shredded and baled municipal waste being placed in landfill was 20 per cent heavier than the non-shredded waste.
Another owner said the in-situ density at his landfill was three times that of the incoming waste stream once it had been shredded and compacted. And a municipality in America, which has four shredders on its landfill sites, believes shredding the waste has extended the landfill life by seven years.
“Imagine how much money an operation could save if recoverable at transfer stations were higher and transport payloads increased by 20 per cent,” Paul says.
Applications
Paul says the design of the M&J Shredder allows it to cut through the hardest of shredding applications.
“Whether it’s municipal waste, C&D or construction and industrial, all timber types, light gauge aluminium and white goods, tyres or even cars, the M&J 4000M can handle it with low operating costs and up to 100 tonnes per hour (tph),” Paul says.
“If waste volumes require higher capacity than that, the 4000M has a big brother – the 6000M – that can produce up to 200tph, dependent on the application.”
Paul says it an operation needs material shredded at a high production rate with minimal downtime, chances are the team at Tutt Bryant Equipment can help.
Proof of his confidence in the shredders, Paul’s happy to refer potential customers to existing customers to directly discuss the performance of the machine. Stock units are also available for inspection.
