Model ALLU Transformer D-Series (DS 3-23 / 40 XHD)

Rethinking Gypsum Board Waste Management

Efficient waste processing is critical for industries dealing with large volumes of construction materials, and Gyproc S.p.A., part of the Saint-Gobain Group, faced this challenge on a major scale. With three production plants across Italy—Asti, Rimini, and Guglionesi—the company generates between 1,000 to 5,000 m³ of plaster board waste per month.

Traditional waste handling methods were proving inefficient and costly, prompting the company to look for a more sustainable and cost-effective solution to process plaster board waste directly on-site.

Gyproc S.p.A. optimized plaster board waste processing by crushing, screening, and refining material directly on-site with the ALLU Transformer D-Series.

The Challenge: High Maintenance and Operating Costs of Traditional Crushing

At Gyproc’s Milan headquarters, the company relied on a REV crusher already available on-site. However, this approach came with several drawbacks:

  • High maintenance and operating costs – The stationary crusher required frequent servicing, increasing overall expenses.
  • Additional machinery required – A separate excavator was needed for loading, adding fuel and labor costs.
  • Limited flexibility – The fixed crushing system meant additional handling time and transport logistics.

With increasing waste volumes, Gyproc needed a solution that was mobile, efficient, and cost-effective, without compromising processing quality.

Gyproc S.p.A., part of the Saint-Gobain Group, needed a cost-effective way to crush and screen large volumes of plaster board waste without relying on high-maintenance crushers.

The Solution: ALLU Transformer D-Series – A Mobile, One-Step Approach

To replace the high-maintenance stationary crusher, Gyproc introduced the ALLU Transformer D-Series, specifically the DS 3-23 / XHD 40 equipped with long hammers on the center drum, mounted on their Volvo L110G wheel loader.

This upgrade enabled crushing, screening, and refining of plaster board waste in a single operation, eliminating the need for a separate crushing unit. With the ALLU D-Series, Gyproc:

  • Reduced equipment needs – The wheel loader handled both processing and loading, eliminating the need for an additional excavator.
  • Lowered operational costs – Fewer machines running meant significant savings on fuel, labor, and maintenance.
  • Increased efficiency – Waste was processed directly on-site, reducing handling time and transport needs.
Plasterboard Recycling in Italy

The Results: Faster Processing, Cost Savings, and a Quick ROI

To validate the efficiency of the ALLU D-Series, Gyproc conducted a two-day trial, testing both capacity and final product quality. The results demonstrated clear benefits:

The company previously spent €16,000 per month on the REV crusher, including maintenance and additional operating costs. The ALLU Transformer purchase cost was recovered in approximately six months, making it a highly cost-effective solution. Additionally, with the wheel loader now handling both processing and loading, Gyproc no longer needed an extra excavator, further streamlining operations.

This more efficient and mobile approach helped Gyproc improve material recovery, reduce costs, and simplify its waste processing workflow.

Expanding the Success Across Italy

Following the success of the ALLU D-Series screening bucket, similar setups were adopted by multiple companies across Italy, including:

  • Gessi del Lago d’Iseo (GR) – DS 3-23 / 40 XHD
  • Knauf Interni (PI) – DN 3-17 / X75
  • Biondi Srl (PG) – SC 3-15 / 35 XHD
  • Lafarge Gessi Spa (AQ) – DS 3-23 / 40 XHD
  • Gyproc (Saint-Gobain Group, Milan) – DS 3-23 / 40 XHD

The introduction of the ALLU Transformer D-Series at Gyproc’s Milan plant set a new benchmark in waste management, proving that mobile, on-site processing can replace high-maintenance crushers while delivering significant cost savings.

Looking Ahead: Smarter Waste Processing for a More Efficient Future

With the success of the ALLU D-Series, Gyproc has demonstrated that on-site waste processing is more efficient, cost-effective, and sustainable. By investing in mobile screening technology, they have optimized their production workflow, reduced their environmental footprint, and set a new standard for smarter material handling in the gypsum industry.

COST EFFECTIVE CRUSHING
ALLU screening buckets transform contract crushing & screening business

When Leicestershire-based MRD Plant, which provides nationwide services to the UK recycling, construction, quarrying & mining sectors, first invested in a second-hand ALLU screening bucket just over a year ago, they quickly realised the benefits of this innovative Finnish-manufactured hydraulic attachment. Since then, they have added three new models to their machinery fleet, all supplied by dealers Blue Group.

“The ALLU screening bucket is so much more efficient, productive and less expensive than bringing a mobile crushing plant on to the work site…”

They were initially attracted to the ALLU DS 3-23 screening bucket after securing a series of relatively small crushing and screening contracts, as it was more cost-effective for their clients than employing an expensive mobile crusher on the job site. Earlier this year, they took delivery of a brand-new ALLU DH 4-17 model, primarily to process asphalt road planings that would otherwise end up in a landfill.

MRD Plant’s Managing Director, Tom Chapman, has nothing but praise for the ALLU transformer buckets, which can screen, crush, pulverize, mix, and separate a wide range of materials. If the material is particularly wet or dirty, they are far more efficient at processing it than a standard mobile screener.

Using the machine’s hydraulic system, the ALLU screening buckets—virtually converting your excavator or loading shovel into a mobile processing plant—are user-friendly and allow for quick attachment, ensuring easy control and operation. With interchangeable blades and spacings of various sizes, you can easily adjust the particle size to meet the different requirements of job sites.

“In many cases, an ALLU screening bucket is much more efficient, productive, and less expensive than transporting a mobile crushing plant to the work site. That’s something we began to realize when we invested in that second-hand model last year. Some of the contracts we secure now involve processing just a few hundred tonnes of material over a couple of days, and it would have been inefficient to set up a standard mobile crusher on-site.

Had we done that, we would still have to use a loading shovel to feed the crusher. The fact that we can fit an ALLU screening bucket to the shovel means we are literally halving our fuel costs and using less labour on-site,” said Tom. “As a result, we can pass those cost savings on to our clients, which they appreciate.”

The ALLU DH 4-17 screening bucket, one of the largest in the D-Series range, is specifically used by MRD Plant to process road planings. However, it can also screen and separate various other materials, including different soil types, sand, gravel, topsoil, compost, demolition waste, biomass, processing, and products of different fractions. This makes the D-Series suitable for various applications, including construction, excavation, recycling, landscaping, and agriculture.

DOING MORE FOR LESS


More or less permanently fitted to a 35-tonne Hitachi Zaxis 350-7 excavator, the ALLU DH 4-17 screening bucket is in constant use.

“It essentially does the same job for less than a top-of-the-range mobile crusher,”

added Tom, who established MRD Plant in 2022 after working alongside his father in a similar business before it was sold in 2019.

Tom Chapman, Managing Director, MRD Plant

“Apart from the versatility of the ALLU screening buckets, I was also attracted to them because of their simplicity. They are easy to use and much easier to maintain compared to a standard mobile crusher. Plus, being fitted to an excavator or loading shovel, they enable us to access restricted sites where we might not be able to bring in a separate crusher unit.”

The other three ALLU buckets in the MRD Plant crushing and screening division are fitted to two JCB loading shovels and a smaller Hitachi excavator. They are easily interchangeable to suit various applications. One of the ALLU transformer buckets has been used to break up and screen Pulverised Fuel Ash (PFA), also known as fly ash, which can then be partly used as a cement substitute in the manufacture of concrete blocks. Extremely wet PFA would be impossible to screen using a conventional mobile screener, and this material would normally end up going to landfill.

In just a few short years, Tom Chapman has built MRD Plant into a successful and growing contract crushing and screening operation that can take on projects ranging from small-scale work to larger, long-term contracts. In addition to the ALLU buckets, he currently operates two mobile crushers, three excavators, and five loading shovels.

PLANT HIRE DIVISION


The business also includes a plant hire division with an expanding fleet of excavators, loading shovels, mobile jaw crushers, and screeners, all available on either an operator or self-drive rental basis.

The plant hire division also offers a variety of ALLU transformer buckets, which are not only limited to aggregate processing but can also be used to meet the requirements of almost any application—from pipeline filling and compact soil processing to highway construction and asphalt recycling. These buckets serve a range of sectors, including quarrying and mining, and wood chip & biomass production.

Since starting the company, Tom has enjoyed a highly successful working relationship with both Blue Group and ALLU.

“They have been very supportive and have put in a lot of effort to ensure we have screening buckets that work for us, especially with the DH 4-17, which we primarily use for processing asphalt. Any issues or queries we have are dealt with promptly and efficiently, and we look forward to building on that relationship going forward.”

With interchangeable blades and spacings of various sizes, you can easily adjust the particle size to meet the different requirements of job sites.

“In many cases, an ALLU screening bucket is much more efficient, productive, and less expensive than transporting a mobile crushing plant to the work site. That’s something we began to realize when we invested in that second-hand model last year. Some of the contracts we secure now involve processing just a few hundred tonnes of material over a couple of days, and it would have been inefficient to set up a standard mobile crusher on-site.

Had we done that, we would still have to use a loading shovel to feed the crusher. The fact that we can fit an ALLU screening bucket to the shovel means we are literally halving our fuel costs and using less labour on-site,” said Tom. “As a result, we can pass those cost savings on to our clients, which they appreciate.”

The ALLU DH 4-17 screening bucket, one of the largest in the D-Series range, is specifically used by MRD Plant to process road planings. However, it can also screen and separate various other materials, including different soil types, sand, gravel, topsoil, compost, demolition waste, biomass, processing, and products of different fractions. This makes the D-Series suitable for various applications, including construction, excavation, recycling, landscaping, and agriculture.

DOING MORE FOR LESS


More or less permanently fitted to a 35-tonne Hitachi Zaxis 350-7 excavator, the ALLU DH 4-17 screening bucket is in constant use.

“It essentially does the same job for less than a top-of-the-range mobile crusher,”

added Tom, who established MRD Plant in 2022 after working alongside his father in a similar business before it was sold in 2019.

Tom Chapman, Managing Director, MRD Plant

“Apart from the versatility of the ALLU screening buckets, I was also attracted to them because of their simplicity. They are easy to use and much easier to maintain compared to a standard mobile crusher. Plus, being fitted to an excavator or loading shovel, they enable us to access restricted sites where we might not be able to bring in a separate crusher unit.”

The other three ALLU buckets in the MRD Plant crushing and screening division are fitted to two JCB loading shovels and a smaller Hitachi excavator. They are easily interchangeable to suit various applications. One of the ALLU transformer buckets has been used to break up and screen Pulverised Fuel Ash (PFA), also known as fly ash, which can then be partly used as a cement substitute in the manufacture of concrete blocks. Extremely wet PFA would be impossible to screen using a conventional mobile screener, and this material would normally end up going to landfill.

In just a few short years, Tom Chapman has built MRD Plant into a successful and growing contract crushing and screening operation that can take on projects ranging from small-scale work to larger, long-term contracts. In addition to the ALLU buckets, he currently operates two mobile crushers, three excavators, and five loading shovels.

PLANT HIRE DIVISION


The business also includes a plant hire division with an expanding fleet of excavators, loading shovels, mobile jaw crushers, and screeners, all available on either an operator or self-drive rental basis.

The plant hire division also offers a variety of ALLU transformer buckets, which are not only limited to aggregate processing but can also be used to meet the requirements of almost any application—from pipeline filling and compact soil processing to highway construction and asphalt recycling. These buckets serve a range of sectors, including quarrying and mining, and wood chip & biomass production.

Since starting the company, Tom has enjoyed a highly successful working relationship with both Blue Group and ALLU.

“They have been very supportive and have put in a lot of effort to ensure we have screening buckets that work for us, especially with the DH 4-17, which we primarily use for processing asphalt. Any issues or queries we have are dealt with promptly and efficiently, and we look forward to building on that relationship going forward.”

Model ALLU Transformer DN 3-17 screener crusher with TS 25 crushing Axe blade setup

Problem

On a site set aside for construction, demolition waste, including concrete, wood, metal and fines cannot be processed further, with the area needing to be cleaned and the material dealt with before any new buildings could be built. 

Solution

The waste was processed with an ALLU Transformer screener crusher. About 30% of the material could be reused as a construction material, with about 10%, including the wood and metal, being separated and recycled properly. The rest of the material comprised of concrete which was crushed and reused as sub base and for foundations.

Benefit

By processing the waste with the ALLU Transformer screener crusher, there were considerable savings made in landfill fees and transportation costs as only about 10% was transported to landfill. The rest of the material was reutilized on the new construction site.   TRANSFORMING YOUR GREEN CREDENTIALS.
