ALLU’s Screening Bucket quickly became two for Garnborns Åkeri & Maskin AB. The flexible, high-quality buckets fit perfectly into their various operations and bring benefits in the form of time savings, reduced costs, and environmental gains.

Garnborns Åkeri & Maskin AB was founded back in 1964 by Göran Garnborn and is today run by his sons Niklas and Joakim. The company is still based in Ronneby, Blekinge, but much has changed since father Göran started the business with a 1952 Volvo BM 35. Today, the company employs 70 people and operates an impressive fleet of machinery and trucks. Around ten years ago, they added their own recycling facility, and five years ago they developed a new area where they built their own wash hall and warehouse for the business.

A business with many legs to stand on

Today, Garnborns Åkeri & Maskin AB’s operations can be divided into three main areas: haulage, contracting, and recycling. High flexibility has been a conscious goal, clearly reflected in the haulage operation, where a large number of hook-lift trucks are in use. The company currently operates around 30 trucks, serving both internal needs and external customers.

On the contracting side, their machinery fleet consists of approximately 25 machines ranging from 2 to 33 tonnes. Their clients include municipal companies, the Swedish Fortifications Agency, the construction sector, and a certain number of private customers.

Ten years ago, the company established its own recycling facility, which we visit on a mild winter day in mid-November. Here, their trucks deliver excavated materials and other materials generated through their contracting operations. The materials are processed on-site and then reused in their own projects or sold to external customers.

“We want to maintain full control over what comes in, and we also sample all incoming material. With today’s regulations, this is necessary even though we only recycle material from our own projects,” explains Joakim Garnborn.

More on-site recycling motivated the investment in ALLU Buckets

Despite having their own recycling facility and trucks, Niklas and Joakim Garnborn felt there was still room to improve material flow in their projects. From an efficiency standpoint, it is not optimal to excavate material, transport it away by truck, and then replace it with other material delivered by truck. This led to a desire to reuse and refine more material directly on-site — bringing them into contact with ALLU.

“There are several benefits to increasing on-site material recycling. Sometimes job sites are tight, and trucks simply don’t have enough space. If we’re working in residential areas, residents naturally want as little truck traffic as possible. From a purely economic perspective, it’s also most cost-effective to recycle as much material as possible on-site, provided the site conditions allow it. Finally, there’s a clear environmental benefit in reducing unnecessary transport. So it’s not just one advantage — we’re ticking several boxes by working this way,” explains Niklas Garnborn.

The ALLU bucket handles a wide range of materials and fractions

At the recycling facility in Kallinge, the company’s ALLU DS 4-17, TS16 (TS32) is currently mounted on a Hitachi ZW 250 wheel loader in the 20-ton class. It is equally well suited for larger excavators, as it is equipped with a combination mounting that includes large BM as well as S70/S80.

The machine is operated today by Thomas Ottesen, who has over 20 years of experience in recycling and material processing. He shows us around the well-organized facility, where all materials are neatly arranged — whether awaiting processing or transport to customers. Although Thomas has only used the bucket for a short time, he finds it easy to learn and especially appreciates its flexibility.

“We’ve processed compost material containing branches and stumps, excavated material, soil, and crushed asphalt — without me even needing to leave the cab. If necessary, I can adjust the drum configuration or even replace them with different ones. But being able to handle such varied materials without changing anything is impressive,” notes Thomas Ottesen.

Perfect bucket for backfilling

Garnborns Åkeri & Maskin’s second ALLU bucket is the DL 2-17. It is smaller in size and has two drums — half as many as their DS 4-17. They were looking for a more specialized product, and low weight was a key requirement.

“When we work on water and sewage projects, we encounter the same challenges I mentioned earlier. It’s about cost efficiency, minimizing environmental impact, and the logistics of getting trucks to the site. If we can sort out our own material for backfilling, the savings can be significant. Thanks to the ALLU DL 2-17 being a small and lightweight bucket, we can easily mount it directly on the tiltrotator of our excavators. This allows us to backfill by sorting the excavated material directly on-site,” explains Joakim Garnborn.

The opportunity for a real demo was decisive

After testing a number of different solutions for on-site recycling, Garnborns Åkeri & Maskin AB now feels they have finally found the right one. The ability to test the buckets in real working conditions before purchase made the decision both easier and more accurate. They quickly gained a positive impression of both the products and the sales representative from ALLU Sverige AB, but the opportunity for a proper demo ultimately made the difference.

“We had the luxury of testing the buckets both at our own recycling facility, where there’s a wide variety of materials, and out in the field before making an investment decision. After that, both buckets went straight into active projects, and everything has worked exactly as well as we had hoped,” concludes Niklas Garnborn.

    Soil Recycling Co. is at the forefront of soil screening in Australia, dedicated to promoting the reuse of soil as a valuable resource rather than disposing of it in landfills. This innovative company specializes in soil handling and recycling, collaborating with major waste management firms like ResourceCo to transform organic waste into usable products such as soil mixes for gardening and landscaping. Currently, Soil Recycling Co. is working at the South Gippsland Highway, Hampton Park in Victoria.

    Founded in 2012, Soil Recycling Co. emerged from a passion for soil and organics, recognizing the inefficiencies in how materials were handled. The company saw countless trucks transporting soil and organic materials, only for them to return to the site soon after. This inefficiency sparked the mission to make onsite resources usable, eliminating unnecessary transport and fostering sustainable practices in the industry.

    Chris Keay, the Director of Soil Recycling Co.

    When Chris Keay, the Director of Soil Recycling Co., faced the challenge of processing wet, clumped soil that affected the performance of the Terex Ecotec Trommel, he recognized the necessity for a more effective solution. Two main issues arose due to the damp and wet soil:

    • Less aerated soil resulted in clumps clogging the hopper and Trommel.
    • The operator, Craig Jameson, had to clean the trommel multiple times a day, leading to significant downtime and fatigue, thus affecting productivity.

    Initial attempts with another type of screening bucket featuring outdated drum technology failed to break down the lumps and dense soil, resulting in clogging and drastically reduced production. In search of a more reliable option, Chris Keay reached out to Walkers Hammers on September 16th, 2024, and discovered the innovative screening solutions from ALLU.

    After reaching out to Walkers Hammers, Chris was introduced to Sami Rahman, the ALLU area sales manager based in Melbourne, Victoria. Together, they identified the ALLU DN 2-12 with TS 25 Axe as the optimal bucket for the demo. Sami, along with Carlo Costanzo from Walkers Hammers, prepared the rental bucket for a demonstration scheduled for September 17th. Upon arriving at the site, it became clear why the Trommel Screener had been struggling; persistent rain had saturated the soil, complicating the processing.

    Once installed on the Hidromek excavator, the ALLU bucket quickly demonstrated its capabilities. The unique TS drum setup, designed for anti-clogging, optimal flow and self-cleaning, allowed for effective processing, leading to significant improvements in output. Impressed by its performance, Chris decided to keep the rental bucket for ongoing use, ensuring he had the right equipment to tackle his challenges effectively.

    To further enhance productivity, the decision was made to switch from TS 25 to TS 50 blades, allowing for better fragmentation of larger soil lumps. Carlo from Walkers Hammers took the bucket back for the blade change, although it could have been done onsite. The bucket was delivered the next day with the blades changed to TS 50, ready for action.

    Operational Highlights:

    September 18: ALLU bucket installed in the morning; processed 310 m³ of topsoil for the remainder of the day (measured from the monitoring system installed on the Terex Ecotec Trommel).

    September 19: Next full day of operation with the ALLU bucket, processing 280 m³ of topsoil due to the poor weather with heavy rain.

    September 20: To be able to compare the customer decided to use the GP bucket the full day which resulted in approximate 20% lower efficiency than the ALLU bucket, and required frequent cleaning due to clogging issues.

    The following are production figures with ALLU and GP bucket after the demo/test:

    In addition to enhancing productivity, the ALLU Variable Drum allows customers to bid on smaller jobs, reducing reliance on larger trommels. Immediately, the productivity of the Terex Trommel increased by 10-20% with the smaller ALLU rental bucket, and with the new purchased DN 3-12 TS VD further great efficiency is anticipated. This capability not only streamlines operations but also promises a quick return on investment, making it an attractive option for contractors looking to optimize their resources.

    This collaboration highlights the strong partnership between ALLU and Walkers Hammers, reflecting our commitment to delivering efficient solutions. Together with Walkers Hammers and our valued customer, Soil Recycling Co., we are dedicated to providing sustainable solutions and efficient waste management.
