We report on all aspects of woodworking from board materials, wood treatment to machines, tools and technical know-how, from timber engineering supplies to the latest developments in technologies and markets. We address factory managers and production engineers directly, and thus ensure coverage of the decision makers within the industry.

SUSTAINABILITY Wood

SUSTAINABILITY Wood briquettes are good for the environment and your wallet When processing wood, shavings and wood residues are generated, sometimes in large quantities. This can be a valuable raw material, if it is processed into briquettes using high-quality machinery. According to Andreas Jessberger, Sales Manager at RUF Briquetting Systems, wood briquettes are a sustainable fuel for many households and an important alternative to fossil fuels. They also hold great economic potential for the timber industry and wood-working trade. the investment pays for itself within a few years. The service life of the RUF briquette press is several times longer. At the same time, the operation of the machines is simple. All that needs to be done is to collect the dry chips and fill them into the hopper of the press via a conveyor system. The finished wood briquettes then fall out of the machine and are usually packed manually or semiautomatically directly afterwards – usually in 10 kg packages. If the wood briquettes are packed and stacked on pallets fully automatically, RUF briquetting presses can be operated in unmanned 24/7 shifts. Only monitoring of the overall system is then necessary. Wood briquettes are sustainable and ecological. The CO 2 released during combustion is bound again in the growing forest – it therefore circulates in a cycle. The specific pressing pressure of the RUF systems designed for wood is 1,700 kg/cm 2 . Jessberger comments: “Thanks to the high pressure, these plants produce briquettes with such high density and strength that no binders are ever needed.” A fact that makes the production process simple and cost-effective. Energy costs have been rising continuously since the beginning of 2022. Especially fossil fuels such as oil and gas are becoming permanently more expensive and are finite resources that release CO 2 during combustion. They are therefore a burden on the environment and increasingly also on the wallet of the end consumer, which makes private households in particular look for alternatives. That is why wood-burning stoves and fireplaces are being used more and more. Wood fired boiler heating systems with buffer storage and pellet heating systems are also being installed increasingly. Wood-burning stoves have an important advantage here: both logs and wood briquettes can be burned as regenerative fuels. In Germany alone, there are now more than 10 million individual fireplaces in households and the annual consumption of wood briquettes is almost one million tonnes – and rising. Although the prices for regenerative energy sources are also rising, “on a long-term average, wood briquettes are significantly cheaper than fossil fuels,” explains Andreas Jessberger and adds: “At the same time, they are sustainable and ecological, because when the wood briquettes are burned, only as much CO 2 is released as the forest binds through sustainable cultivation – the CO 2 is therefore in a cycle.” Moreover, primary wood is not typically used for briquetting. Rather, wood by-products are used, as they are produced as “waste” during wood processing. Briquetting is important for a functioning CO 2 cycle The decisive factor here is that companies in the timber industry and the woodworking trade do not dispose of their chips arbitrarily, but rather forward them for further processing by briquetting. Even for medium-sized companies with a chip volume of 100 tonnes per year, it is worthwhile to purchase their own press, such as the RUF 100. Through the sales revenue alone, Wood briquettes burn with low emissions and form good embers Wood briquettes made from uncontaminated material are ideal for the home stove and provide a pleasant and long-lasting warmth. They burn with low emissions and little ash, while also forming a good ember. Whether hardwood or softwood briquettes are burnt does not make much of a difference, because the density produced is very similar. The heating values of both types of briquettes are also almost identical and, at around 5 kWh/kg, are higher than that of logs. The decisive factor here is the briquettes’ low water content of around ten percent. With air-dried logs, this can be up to 20 percent. Another advantage of the briquettes is that they require significantly less space for storage. Especially the rectangular RUF variants can be stacked perfectly in the house with minimal gaps. A pleasant side effect: wood briquettes are free of any other dirt and insects. www.brikettieren.de 30 No. 1 • March 2023

EVENTS TechTogether@Hymmen in-house exhibition Production technology and industry intelligence to experience and touch Hymmen was delighted with the lively interest shown at the 2nd edition of the OWL-wide Tech-Together in-house exhibition event. Around 60 visitors from all over Europe took the opportunity from 18 – 20. October 2022, at the Hymmen Technical Center in Rödinghausen to see new and proven products: from digital printing technology to press and coating systems and the Industry Intelligence solution smart2i. From Tuesday to Thursday visitors took part in exciting live demonstrations on the Digital Lacquer Embossing (DLE) line and the production systems for digital decor printing on board material with UV-curing inks (JUPITER) and water-based digital printing of decor paper (SATURN). Next door, the HPL double belt press was waiting to press digitally printed paper into laminate on site. Hymmen’s coating finishing technology (Calender Coating Inert, CCI) can produce outstanding quality mirror high gloss as well as super matt surfaces, which were also on display. The latest of the innovations presented is equally relevant for all Hymmen-owned as well as for external machines and systems. It is the smart2i Industry Intelligence solution samrt2i, for cloud-based monitoring and analysis of all relevant process parameters to optimize the entire production. The live application of smart2i could be experienced in real time by means of the monitoring and analysis of the current production data of the technology in operation at the fair. The practical presentations were accompanied by talks on AI and the Industry Intelligence solution smart2i from Hymmen. Carsten Brinkmeyer, Head of Business Development at Hymmen, put the Industry Intelligence solution smart2i into a larger theoretical context. Guest speaker Wilhelm Klat (M. Sc.) gave a keynote speech on artificial intelligence. Mr. Klat is a Computer Vision Specialist, a research associate of the Applied AI Working Group at the FH Bielefeld and Managing Director of CircoVision UG. Dr. René Pankoke, managing partner and CEO of Hymmen led the following podium discussion. www.hymmen.com No. 1 • March 2023 31
