The dream team for wood disposal

CNC World, a British vendor of CNC machines, has recently started to process its wood waste mechanically in order to heat the workshop in a resource-saving manner. The combination of shredder and briquette press has proven to be a real dream team.

For many years CNC World Ltd. has been selling automated position cutting systems such as CNC milling machines, plasma and water jet cutters and lasers. As part of its expansion in Norwich, Great Britain, the machine specialist was able to extend its demonstration area and advance the recycling of wood waste.

Valuable Waste


When wood is processed with CNC machines, waste is often produced from the offcuts. Over time, large amounts of excess wood waste can accumulate. The disposal of this waste can be very expensive. Although in-house recycling initially involves investment costs, it offers many advantages in the long term.

CNC machinery with extraction

With FERCELL (the British dealer for WEIMA machines) as a consulting partner, CNC World has chosen a complete solution from WEIMA. The scrap wood is first shredded with a WEIMA WL 4 single-shaft shredder and then pressed into stable briquettes using a WEIMA C 140 briquetting press. The wood briquettes are then burned in a wood-burning oven. This way the workshop can be heated and additional costs saved.

Robust and low maintenance: the WEIMA WL 4


The WEIMA WL 4 shredder is a proven classic in the product portfolio of the shredding specialist from Ilsfeld. It shreds wood waste of all kinds and is in use in thousands of wood processing companies all over the world. The machine is characterized by a very robust design and extremely long service life. With a rotor diameter of 252 mm, a rotor length of 600 mm and an output of up to 18.5 kW, the WL 4 shreds any wood waste at a high throughput volume to a homogeneous grain size. The WAP gear developed by WEIMA is manufactured exclusively by WEIMA and is extremely maintenance-friendly, low-wear and resistant to foreign material.

Briquetting saves space and costs


Once the material is shredded, it can be processed into briquettes. The compact and low-maintenance C 140 briquetting press from WEIMA was the optimal solution for the requirements of CNC World. The machine has a throughput of 40 kilograms per hour and is therefore particularly suitable for small and medium-sized companies. With the C 140 CNC World compacts its shredded wood waste into solid briquettes – the addition of binding agents is completely unnecessary. The volume of wood waste can thus be reduced by up to 90 percent. This saves space and is cost-efficient. The highly compacted briquettes with a diameter of 40 mm are particularly suitable for combustion in a wood-burning oven, as their calorific value is comparable to that of lignite. Thus, CNC World can heat its own buildings in an environmentally friendly and cost-saving way.

Shredding, briquetting and subsequent burning of the waste material offers CNC World a sustainable alternative to heating with fossil fuels. The briquettes that are not used for heating can also be sold to generate additional income.
