With Lack of Raw Materials, Rising Prices, Solutions Come From Waste Material

It’s a problem affecting everyone, from suppliers to their customers: we’re in the middle of a supply shortage.

The planetary crisis behind finding aggregates has hit all sectors, mechanics and construction and doesn’t seem to have an end in sight.

Prices also change from month to month, becoming unsustainable for companies already struggling to meet all of their orders. The jobs are there, but no one knows when they’ll finish them; public and private works risk delaying their construction sites and struggling to recover.

“One of the first things that came to mind about this problem was to manage our materials to become more autonomous and not depend on third parties for everything,” a company, who handles demolitions in Belarus, said.

“When dealing with demolitions, we have a lot of rubble to dispose of on-site — reinforced concrete, bricks, tiles, reinforced poles, etc. — so we asked ourselves, ‘why not process this rubble directly on-site and reuse them?’ Above all, how do you successfully carry out this process?”

How did they give waste materials a second life? Using a BF70.2 crusher bucket to reduce the material’s size, add an MB-S18 screening bucket and they cleaned and sorted the material on-site with their two excavators. With two attachments and one excavator, they produced quality material themselves, all ready to be reused.

With MB Crusher’s equipment, the rubble becomes a resource capable of keeping the construction site active, even on locations where there aren’t materials readily available, or in areas with difficult access, or within cities while managing restrictions, and be watchful of noise and dust emissions. The whole process takes place on-site and transforms waste crushed and selected to become excellent recycled material. A practical and economically advantageous method makes the process perfectly autonomous, lets them save time and money with disposal fees, and purchasing new materials. Once transformed, the “clean” rubble can be reused for other jobs, for example, as a foundation to construct new roads. Recently, in Serbia, after demolishing an old commercial building, the mix of bricks, reinforced concrete and demolition materials has been used to construct the subgrade of the streets in the area. Time and the costs of transporting, disposing, and purchasing new material have been eliminated. All due to the MB80.3 crusher bucket installed on the excavator that is already on site.

By facilitating the construction during the process to recover demolition materials, one helpful tool is the MB Crusher sorting grapples.

“These are agile and practical machines, perfect both for demolition and when handling post-demolition materials,” said an Italian project manager.

The winning feature of MB’s grapples is the unit’s grip sensitivity: it allows extreme precision and progressively increases the closing force.

Due to the interchangeable claws and the 360 hydraulic rotation, they managed larger loads and odd shapes despite the confined space.

With MB Crusher’s machines, you receive the advantages of an ethical process when recovering demolition materials, which extends to the environment and community. Due to reusing materials, companies don’t have to worry about disrupting the area’s ecosystem, reducing vehicles traveling to and from the demolition area, and decreasing noise and dust emissions. Fundamental discussions surround how responsible companies are becoming more aware of the circular economy-oriented market.

MDS International manufactures heavy duty and recycling trommels, apron feeders and conveyor systems (pictured left), a product range that complements other Terex brands such as EvoQuip (pictured right).

Terex Materials Processing (MP) announced the purchase of MDS International (MDS), a manufacturer of heavy-duty and recycling trommels, apron feeders and conveyor systems, based in Co. Monaghan, Ireland.

MDS was founded in 1995 by Liam and Una Murray, with a vision to design and develop engineering solutions to industry. Over the past 25 years MDS has built a highly skilled work force along with global distribution partners, and has a valued reputation for innovation, offering bespoke solutions to serve client needs with equipment that can withstand the harshest of environments.

This acquisition supports Terex MP’s growth strategy to expand its offering in the crushing and screening and environmental industries, with products that complement the existing portfolio.

Trommels from MDS are heavy duty trommels that will enable expansion into areas of the market that Terex MP does not currently serve. Additionally, Terex MP expects strong commercial synergies from this deal, as several Terex MP distributors already carry the MDS line, while others will be new to Terex, offering the potential to develop new channel partner relationships. MDS’ 34,000 sq. ft. facility will be the first Terex location in the Republic of Ireland, which diversifies its footprint and provides access to a new labor pool. Additionally, the facility is within a short driving distance to the Terex Dungannon and Omagh sites, providing ready access to Terex MP’s Northern Irish team and enabling close coordination with the resources at these facilities. The MDS facility and its highly skilled team members will be led by Conor Hegarty, general manager and business line director. Previously, Hegarty held the position of international sales director of Terex Ecotec, and his commercial background and product knowledge will be a huge asset as he takes leadership responsibility for MDS, the company said. MDS will remain a standalone brand along with Terex MP’s Crushing and Screening businesses including Powerscreen, Terex Finlay and EvoQuip. Terex MP will build on the momentum of MDS International’s long-standing reputation, continuing to develop the brand, its product portfolio and its distribution channels. Commenting on the announcement, Pat Brian, vice president, mobile crushing and screening, Terex MP said, “The addition of MDS to our portfolio of businesses will bolster our growth and improve our product offering. The business has been well managed, is on a terrific growth trajectory, and its heavy duty trommels address a gap in our own product lines while also having a lot of synergy with what we already manufacture and distribute.” Liam Murray, co-founder of MDS International said, “I am so proud of how MDS has grown over the past 25 years — to have a multinational company like Terex interested in our business is a testament to what we have achieved. MDS will now have the global resources of Terex to develop and grow it to new levels; I feel this is the right move for our business and team. This sale will also bring new levels of support to customers and dealers worldwide. I will always care deeply for our MDS family and will remain on board for a period of time, in order to support a smooth transition to Terex ownership.” For more information, visit www.terex.com. 
