Efficiency Test in Recycling of Waste Wood
Two machines from Arjes demonstrated their respective capability in shredding wood.
According to German manufacturer Arjes, the efficiency and performance of two shredding machines for processing waste wood were put to the test at the Biomassehof Chiemgau in Bavaria: the new EuRec S-850 (an Arjes brand) and the well-established ARJES VZ 850. The goal of the comparison test was to evaluate the quality of both machines in shredding pallet wood.
The ARJES VZ 850, powered by a robust 16-liter diesel engine with 565 kW, is already considered a reliable two-shaft shredder in the recycling industry, the manufacturer of recycling machinery underlined. “Opposite it stood the new challenger, EuRec S-850, equipped with an efficient and environmentally friendly 11-liter diesel engine with 315 kW.” At first, there seemed to be hardly any difference in throughput performance, as both machines reached about 50 tons per hour, the company stated. But the EuRec S-850 emerged as the “winner”. With nearly identical throughput performance, the EuRec shredder produced significantly finer output material. “About 30 tons of shredded wood waste could be processed to a final particle size between 0 and 100 mm. In contrast, the VZ 850, with the same configuration and rotation speed of the shredding shafts, only achieved 25 tons in the 0 to 100 mm range.”
The result
As reported by Arjes, this comparison test demonstrated that the EuRec S-850, despite its smaller engine, delivers excellent performance while producing a finer end product. This assurance would make the upcoming market launch of the new machine appear particularly promising. The opportunity to conduct the test was provided by the Schaumaier Recycling Group at their Biomassehof Chiemgau.
The certified waste management company specializes in accepting waste wood of classes A-I to A-IV for thermal and material recycling. Since 2022, the company has been operating at the Chieming site with the VZ 850. In 2024, another twin-shaft shredder from Arjes, the EKOMAXX 800, was acquired and is set to be used at various locations within the group.
