TANA expands waste pre-shredding portfolio with Multi Waste Buckets MWB17 and MWB23

TANA expands its waste pre-shredding portfolio with the MWB17 and MWB23, bringing pre-shredding directly to the loading stage by combining shredding and bag opening in a single step. This reduces bulky or unsorted materials to smaller pieces and improves feed quality for downstream sorting, screening, recycling, and energy recovery, supporting safer and more efficient operations.

“Pre-shredding is the critical first step in turning waste into value. With the TANA Multi Waste Buckets, we are bringing that step directly into the loading phase, making the process simpler, more flexible, and significantly more cost-efficient for our customers,” says Eetu Tuovinen, Product Marketing Manager, Shredding Solutions, Tana Oy.

Compared with a stand-alone pre-shredder, the MWB reduces the number of machines on site and eliminates the need to power, maintain, and feed a separate shredder. With pre-shredding integrated into the loader attachment, customers typically benefit from lower fuel and service consumption, fewer wear parts to manage, and less unplanned downtime, while also reducing internal material movements and handling steps that add cost and complexity.

Designed to integrate seamlessly into existing operations, the MWB features plug-and-play installation with no additional drain line and fast setup on a wide range of wheel loaders and material handlers, enabling operators to pre-shred exactly where needed and reducing extra material handling.

The MWB line comprises two models with the same proven design and performance; the MWB17 is suited for 10–15 t loaders, while the MWB23 targets 13–20 t machines, ensuring optimal performance across different scales.

The buckets produce a consistent particle size of approximately 300–400 mm and process up to 90 m³/h to optimize feed for downstream processes. Field experience has shown that integrating pre-shredding into the loading phase can streamline site operations.

“Customers have seen immediate benefits in terms of reduced transport needs, smoother material flow, and less downtime in downstream equipment. The ability to pre-process waste on the spot changes how efficiently the whole site can operate,” says Tuovinen.

The three-axle design of the MWB ensures efficient shredding and continuous material flow. A faster middle axle combined with higher torque on the upper and lower axles creates an effective cutting pattern that reduces material wrapping and maximizes throughput. The patented bearing protection, axe-shaped blades, and self-cleaning structure further enhance reliability, durability, and ease of maintenance, enabling operators to minimize downtime and extend component lifetime.

The MWB models share the same proven design and performance, with the only difference being bucket size to match different wheel loader classes and capacity requirements. The MWB17 is suited for 10–15 t loaders, while the MWB23 targets 13–20 t machines, ensuring optimal performance across different scales.

With durable, serviceable components and the option to replace or complement traditional pre-shredders, the TANA Multi Waste Buckets offer a practical first step toward more efficient, profitable, and sustainable waste processing.
