Family-owned SBI Group, in operation for three generations, has transformed from supplying sand and topsoil to landfill and waste management for the building and construction industry.
The independent drill and blast quarry operator started in the early 1970s and obtained a quarrying license for its Cranbourne site in Victoria in the late 1980s, extracting the sedimentary rock that lay deep beneath the sand to supply the local construction industry.
Materials quarried at Cranbourne have been used for several large scale state road projects including the EastLink, Western Port Highway, the Mornington Peninsula Freeway and, more recently, the Mordialloc Freeway.
In early 2020, the landfill side of the business became fully operational, with non-recyclable building and construction waste filling the original quarry, the largest inert landfill in Melbourne’s south east.
Introduction to M&J PreShred 4000M
Paul Williamson, SBI Group Director, is always looking for ways to improve operations. When someone suggested he consider using an M&J Shredder at the landfill, he explored the idea with Paul Doran, Metso Business Development Manager of Tutt Bryant Equipment (TBE). Doran proposed a hire to buy option, enabling SBI Group to evaluate if the Shredder and TBE can both support the business’s high activity.
Currently, a M&J PreShred 4000M shredder is pre-shredding all SBI Group’s inert waste, reducing the size of the material being handled, dramatically reducing the air voids in its landfill, and increasing payloads for transporting recyclable products.
SBI Group has achieved adequate waste compaction with reduced effort; by less compacting hours or by using a smaller compactor providing greater in situ density. The higher compaction capability, combined with a process which recycles construction and demolition material would traditionally end up in landfill, is extending the sustainable life of its landfill for many years.
Michael Lawlor, SBI Group Operation Manager, was a big fan of a competitor shredder before receiving his M&J 4000M. He suggests, “the machine has performed very well, day in day out and never blocks up like other shredders. Not having any lost production time due to clearing blockages means the machine’s shredding availability is amazing.”
The focus on recycling has grown significantly in Melbourne in recent years and SBI Group says the addition of the M&J 4000M shredder was timely. The company took delivery of the machine in September 2020, purchasing the unit after several month of proving.
Williamson is so pleased with the shredder he has advise Tutt Bryant Equipment to “tell any prospective buyers to call me and I will tell them how good the unit is.”
Moeller & Jochumsen (M&J) iron foundry manufacture the M&J 4000M in Denmark. The foundry opened 1857, producing the first waste shredder in 1988.
Known as ‘crawler units’ the M&J 4000M shredder can be moved during operation and is easy to load and transport. Its robust and strong structure, as well as easy to operate, efficient, easy to service, help reduce running costs
M&J waste recycling shredding technology is based on an aggressive knife design and open cutting table. The knives cut in both directions through the table and the shafts run asynchronously, which means they run in any direction required to optimise production.
The units are extremely resistant to wear caused by materials and waste normally considered un-shreddable, such as metal, reinforced concrete, and rocks.
Tutt Bryant Equipment is providing technical support to SBI Group with its ongoing equipment, parts, and service needs, as required.
