Wood Scrap and Wood Waste Shredding

Wood is a valuable raw material that can be used down to the last chip. When processed into wood chips, the wood waste can be used for direct energy generation in combustion plants or for the production of briquettes.

Wood shredding at its best

Anyone who wants to produce energy from their waste in an environmentally friendly way cannot avoid the raw material wood. The residues, which are processed into wood chips by means of shredding, can be used for direct heat generation in combustion plants or for the production of briquettes.

Typical applications are all kinds of hard and soft woods, waste wood, OSB and MDF residues, veneer, plywood, stairs, doors and pallets. And don't worry. Their nails and screws are simply shredded with them. Later they can be easily separated with a magnet.

"The first WEIMA shredders of the 1980s were used for wood applications. Since then a lot has changed from a technical point of view. In the meantime we have also become experts for the corresponding conveying technology".

The different series and rotor variants are the top solutions for wood processors: Whether pallets, sawn timber, chipboard or MDF boards, stairs, window frames, doors or semi-finished wood products – our machines turn everything into valuable kindling.

Waste wood utilization and waste wood processing with WEIMA

No matter what you call your machine. Whether wood chipper, grinder or shredder – with a WEIMA you shred everything to the last chip and dispose of your wood waste sustainably.

As a pre-shredder, the Woodwolf is available for large-volume residual wood waste such as pallets or furniture. With our universally applicable shredders of the WL series, e.g. WL 4 or WL 15 , you can achieve highest throughputs. For even smaller material sizes we offer secondary shredders of the WNZ series .

Material flows under control: Conveying. Separating. Storing

Thanks to our extensive experience with conveyor technology (air extraction, screw conveyors, bunker systems, conveyor belts, metal detection and metal separation), we can offer you the complete package for wood disposal and recycling from a single source. Thus, you are optimally equipped for your own energy production.

Chip bunker with screw conveyor

Every carpenter needs a WEIMA.

This was already the case when we were founded in the 80s and will not change in the future. All joineries, carpentries, joinery, sawmills and (industrial) furniture workshops of all sizes inevitably generate residual wood waste from production. These must be disposed of or made usable. Because: Wood is biomass raw material with future.

Pallet shredding

One of the most common applications of wood shredding is the shredding of pallets. WEIMA offers machines specially designed for this task.

Possibilities for the utilization of wood waste:
1. Use wood chips for combustion
e.g. chip bunker with wood chip firing oven
2. Use wood chips for the production of biogas
e.g. wood gasification plants in bio-heat power plants
3. Briquetting shredded wood and using it for own heat generation
e.g. wood briquettes for wood stove
4. briquetting wood chips and selling them for a profit
e.g. hardware stores or private households
5. Waste wood and used wood recycling
e.g. chipboard production

Why is it necessary to have homogeneous particle sizes when shredding waste wood?

A homogeneous grain size is particularly important in the thermal utilization of wood waste, since heating plants are often designed for a standardized grain size. If the particle size is not sufficiently homogeneous, wood chip heating systems operated with screw conveyors can quickly become clogged. The formation of material bridges also prevents smooth firing of the system.
In addition, the safety of the firing system can be impaired if excessively large or long chips block safety devices such as the rotary feeder.
For the production of high-density briquettes, homogeneous wood chips are essential as well. Only in this way can wood briquettes keep their shape stably without binders and glue.

Optimal recycling of wood waste

No matter whether you use a planer, band saw or circular saw, sander or lathe, woodworking produces a lot of wood chips, sanding dust and sawing waste. Even in CNC machining centers, wood chips and wood dust are produced through the use of CNC machines and milling machines, which can be optimally recycled with a WEIMA shredder.

At Sucker Holzbau GbR a lot of wood waste accumulates over time. With the help of a WL 6 single-shaft shredder and a wood chip oven, this is used to heat the workshops and offices as well as three single-family homes.

Ideas made-to-measure – the rest goes into the WEIMA

For over 110 years the name Althoff has stood for creative work with wood. In the joinery in Bielefeld, wood waste accumulates during all stages of production. With the use of a WEIMA WL 4 shredder, this can be ideally processed to heat the premises.

GARANT – sustainability guaranteed

At GARANT, sustainability is a top priority. For many years, the products have been manufactured in an energy-conscious and environmentally friendly manner. Waste from frame production is also processed further – with a WEIMA WL 6 S single-shaft shredder.
