UNITED KINGDOM - Chippers and shredders for wood-waste
In the UK, D J Laing are leading wood waste recycling specialists. At their Petterden Recycling Centre, collected waste is pre-sorted prior to entering the woodwaste processing stream where a combination of Doppstadt shredders, eddy current separators and screeners treat the incoming waste wood.
The sorting operation ensures that pallet, packaging and virgin timber woodwaste for the “Grade A” end-product is separated to ensure clean, high quality 40 mm chip for board production.
Second grade woodwaste is treated as a separate waste stream to produce biofuel material. A by-product of both processes is -6mm fines cattle bedding which is screened out and stockpiled for use in the agricultural sector.
Currently, the recycling plant is producing around 500 tonnes of reclaimed material per week although the potential output is in excess of 1000 tonnes, which will allow any expansion and future increases in volumes to be handled with ease.
The company was among the first in the UK to recognise the benefits that Doppstadt chippers and shredders could add as an integral part of their woodwaste treatment processing plants.
Having purchased their first Doppstadt LK330 shredder some 15 years ago, the company has retained a Doppstadt in their specialised equipment fleet ever since. “We’ve looked at a number of competitive shredders over the years, “ says Managing Director David Laing “but have remained loyal to Doppstadt and distributors Blue Scotland throughout. Doppstadts are reliable, productive and meet our high quality 40 mm wood chip product the end-user demands”.
D J Laing has recently taken delivery of their fifth Doppstadt, a Doppstadt DZ-750 Kombi combination slow- and high-speed shredder from Blue Scotland, which is now the main woodwaste processor at the company’s Petterden Recycling Centre. The DZ-750 Kombi was chosen because it is specifically designed and built for the shredding of woodwaste and is also ideal for the production of biofuels.
D J Laing diversified into waste management in the early 1990s has seen a planned and programmed expansion of the specialised plant and equipment - shredders, crushers, screeners etc - alongside a continued investment in modern vehicles, processing and material handlers to ensure best practice and optimum reclamation of reusable products, minimizing landfill and maximizing recycling and reuse.
