1. WHY SHRED WASTE WOOD?
Why we need wood shredding for waste wood?
Industrial wood shredding machines and grinders play a key role in waste management and
recycling in today’s manufacturing and disposal industries. They may also be practical for
other businesses or business communities, after careful consideration of security, waste
management costs and the importance of lowering environmental impact.
Wood grinders are available in a range of sizes, on tracks or tires, diesel or electric powered.
They are capable of grinding all kinds of wood waste material, consisting of chipboard, MDF
board, veneers, solid wood, pallets, hardwood, softwood, chips or off-cuts – the
homogenous final product produced in the shredding process is perfectly suited for the
generation of heat for buildings or drying chambers as well as for the production of wood
briquettes.
Types of Shredders
Industrial wood shredders vary in many ways, according to the function they perform. The
internal mechanical processes may include cutting, grinding, hammering and compression.
Many wood shredders also incorporate shaking/sorting mechanisms. Internal machinery
may travel in rotary, lateral or vertical directions. Speeds of the internal processes also vary
widely, to suit the materials the machines will be handling. Shredders can be partially
categorized by the type of process or processes they employ:
Grinders
Grinders use abrasion, often combined with compression to pulverize wood materials,
usually to produce granular products. Wheels, drums and plates may be used in the
processes. These may be either high or low speed machines.
Chippers
Chippers normally use high speed rotary knives to reduce materials to flakes or chips. They
can be manually or automatically fed, and may be single or multiple stage machines. They
may also employ single or multiple drums or wheels with single or multiple knives.
Mobile Wood Shredding Services
There are companies that offer to undertake mobile shredding services for the maceration /
reduction / pulverisation of wood waste. The wood can be shredded on site and even
screened to either 10mm or 30mm to make compost. The wood waste can also be used to
supply feedstock for powers stations, board manufactures and the Equine industry.

2. Advantages of Wood Shredding and Grinding
• The advantages of using mega-shredders in large-scale waste disposal systems, such as
landfill / recycling centres are fairly obvious. Waste wood can be immediately reduced to a
mere fraction of its original size and many can be sold or given directly back to the public for
distribution as useful products.
• Bio-degradable products like wood will decompose faster after shredding.
• Shredding also allows those materials that will end up buried forever in landfills to be
compacted into a much smaller space with fewer voids, resulting in a more stable base for
future development.
• There are sound environmental reasons for putting your ground wood waste in the garden,
instead of land filling it. Land filling wood waste contributes to the creation of methane gas
which is a potent greenhouse gas thought to contribute to climate change.
• Also by using your very own chippings as mulch you will reduce the need to buy chemical
weed controls for the garden.
