Tana delivers the shredding capabilities for GBN Services Ltd.

The HUB team recently visited the Uxbridge site of GBN Services Ltd who are the leading skip hire, recycling and waste company for construction, commercial and household customers across London and the South East.

It’s a huge operation involving 140 skip lorries operating from six sites which over the years has built a strong reputation for reliable service and maintaining maximum recycling through sustainable solutions.

Across all their recycling centres, GBN Services achieves very high recycling levels, which combined with their RDF solution can help deliver 98% diversion from landfill for our customers.

Much of the waste the company process arrives at the recycling centres unsegregated. Where possible, GBN Services use a sorting process to derive valuable materials from their customers’ waste that is ready to be reused. When this waste arrives at the recycling centres, it is firstly separated into major waste streams by grab machines. Waste is then further sorted using a wide range of recycling equipment including; trommels, air separation kinetic flow systems for soils and stone separation ancillary screening equipment and picking belts for manual sorting. The light fraction is processed by shredding and further sorting.

When the waste material is sorted they can then maximise what can be separated for reuse and recycling. The remaining residue is baled and sent as refuse-derived fuel (RDF) to an energy generating plant. Bales are regularly checked to ensure they consistently achieve the exacting standards of the RDF market. At their facilities, the energy embodied in these waste materials is used to generate heat and power replacing the need for use of fossil fuels. This helps their clients reduce their environmental impact.

Their philosophy to invest in new technology as it becomes available enables them to segregate more and more materials and move waste up the hierarchy. For example, their recent investment in Tana shredders which have been supplied by Tana Recycling Machinery (UK) Ltd has given them confidence and more efficiency in this area of the business.

We sat down with the MD - Garry Hobson who told us about his operation and why he chose the Tana Shark 440DT eco.

“The two Tana machines are based at Edmonton and Leyton where the wood shredding is processed. Edmonton is the main site and all waste wood is fed there. It is a 3.7 acres site where we employ 50 out of the 270 staff in the group.

“We were one of the first companies almost 20 years ago to start recycling wood and today we can convert waste wood into a valuable item by generating wood chips for use in fibre board production.”

The company took delivery of their first Tana Shark in January 2019 and they now have two machines with a third ordered for delivery in late June.

Garry, continued, “We have tried every make of shredder prior to Tana and we found that they all had their faults. We settled on Tana because it’s the best machine for the job and the service we receive is first class.

“As well as shredding wood we can also use the Tana as a general waste machine, so its quite flexible in that respect. We are processing approximately 3,000 tonnes/month and have only experienced one minor warranty issue which was resolved immediately so we are very pleased. Great service, great parts availability and a quick response when we needed it, we love the Tana machines!”

GBN have invested in the Tana Shark 440DT eco which is a single-shaft, slow-speed tracked shredder which is driven by a Cummins QSX15 with a power rate of (SAE j1995) (kw) 433.

With a 3000mm rotor length operated at 28rpm the 920mm diameter shaft is equipped with 33 knives.

The machine supplied was specified with an overband magnet, a variable screen/basket and a heavy-duty rotor.

A remote-control system and a SmartSite ™ / ProTrack™  Daily report system, completed the specification.


Ever since 1971, Tana has been in the forefront of designing and manufacturing robust machinery for the purposes of solid waste management. With decades of experience on the needs and requirements of landfill and waste management operators, in the early 2000s Tana expanded its machine selection with the TANA Shark mobile shredders. The core design of the TANA Shark has remained the same throughout the years: a robust, single-shaft slow-speed shredder with enough torque to process even the toughest materials such as used tires or mattresses.

What separates TANA Shark from the competition is its versatility. The TANA Shark can process various different materials, allowing the user take full advantage of various waste streams. TANA Shark’s changeable screens make producing an end-product in various particle sizes easy. The Shark can do both pre-shredding as well as produce a homogenous end-product – one Shark can replace even two machines!
