Taking Care of Waste Wood
Whether furniture, bulky goods or other waste wood: Lindner is a reliable partner.
With a focus on solutions for efficient waste wood processing for co-incineration, Lindner presented at IFAT productive shredding solutions and screening technologies that meet customers’ highest demands for quality and service. Whether Euro-pallets, furniture, bulky goods, roof beams, railway sleepers, construction and demolition waste, rootstocks that are difficult to shred or many other types of waste wood, the Austrian company has extensive experience and is a competent, reliable partner when it comes to the shredding of waste wood for co-incineration or recycling purposes.
It’s all about the end product – energy for 25,000 households
That’s a claim the Altenstadt combined heat and power plant in Upper Bavaria, Germany, can support: Lindner designed and supplied an on-site solution that combined a Urraco 95 shredder as the heart of the plant with a special downstream star screen.
The Altenstadt combined heat and power plant went into operation in 1999 and today supplies more than 25,000 households with energy. Since then, more than one billion kilowatt hours of electricity have been fed into the public grid. The CO2 savings during this period – measured in terms of the electricity produced – amount to more than 620,000 metric tonnes.
Waste wood from grade A I to A III (in accordance with the German waste wood ordinance), sawdust and also fresh wood is turned into highly calorific fuel. The materials normally used are non-directly recyclable timber from thinning, rootstocks, wind-felled timber, weak wood and branches and twigs. As Bernhard Schuster, authorised officer of Heizkraftwerk Altenstadt GmbH & Co. KG, explains, previously this wood would have been mostly incinerated, chopped or left to rot.
After the Lindner Urraco 95 shreds the wood to a specific particle size, metals, plastics, glass and other foreign objects, which may be contained in the input material, are separated and discharged. The downstream star screen filters the material very thoroughly, effectively cleaning the fractions while emitting low noise, minimizing agglomerates and limiting the length of fine particles.
With the Urraco and Miura series, Lindner offers two particularly powerful machine types for perfect waste wood shredding. The twin-shaft mobile shredders are resistant to foreign objects, which can often be found in the waste wood feed in recycling plants: nails, screws, metal plates, glass, hard plastics, etc. With the machines, the focus is clearly on long-term, low-maintenance operation and rapid removal of foreign objects in order to achieve a high degree of productivity.
The Miura 1500 shredder, for example, is the first in the Lindner product range with the FX (Fast Exchange) system – an innovation that is becoming the standard.
