The next wave of pine beetles has already hit many spruce trees during the summer months, resulting in a good portion of our forests dying. As a result, it will be necessary in the coming months to process logs, crown mass and in particular beetle-infested wood into saleable wood chips, which are used as a biomass energy source to replace fossil fuels in many places. And the trend is increasing.

Recycling waste wood can be a profitable business. This largely depends, however, on high material quality, compliance with ever-increasing environmental requirements and ensuring maximum flexibility and cost-effectiveness of the solution.
At BAUMA 2019, Doppstadt will be presenting its proven mixed construction waste processing concept: a screening machine, wind sifter and density separator that are now even more compact and cheaper than before.
Plastic is everywhere, and sadly, it often ends up in many green waste bins. This causes composting site operators a lot of problems: they have to carefully separate unwanted bags and other plastic components from the organic waste in order to comply with legal regulations, including those of the German Fertilizer Ordinance (DüMV). However, composting site operators also want to achieve their own goal and offer high quality products to their customers, who are involved in the compost, gardening and agriculture industries.
Werner Doppstadt Umwelttechnik GmbH & Co. KG (WDU) has implemented a new management structure, bringing the comprehensive restructuring process within the Group to a close. Over the summer, Doppstadt has "set sail for the future" by adjusting its organizational structures and portfolio to the global demands in the recycling markets. The result is a worldwide network of sales and service partners, competence centers for securing innovation and a managing board with the ability to act quickly and efficiently.
Randy Kreider grew up in Lancaster, a quaint small town in rural eastern Pennsylvania. Unless you're inside the urban boundaries of Philadelphia, most of this half of the state is economically driven by agriculture and other natural products. As the owner of Kreider Mulch, Randy has been able to capitalize on those opportunities, turning this once-small bark mulch lot into a successful business that produces more than 150,000 yards annually. He recently built a robust topsoil operation to complement the mulch products.
Doppstadt's INVENTHOR Type 9 shredder, from the SMART SHREDDING LINE, is a new high-performance machine that is setting new market benchmarks when it comes to quality and performance. By bringing together the most innovative mechanical developments, innovative control and regulation systems, and a brand new noise emissions concept, Doppstadt has created an environmentally friendly cost-effective one-stop solution for the recycling sector. Thanks to its modular service-oriented construction and range of suspension variants, this machine is equally suited to use as a stationary fixture or in the service industry sector.
Now available in North America from Ecoverse Industries, the Doppstadt SM 617 Flex trommel is state-of-the-art screening technology with a high price-to-performance ratio, providing all the functions required for composting and organics recycling operations.
"For the forestry and timber industry, the performance, robustness and flexibility of the machines are essential for profitability," says Daniel Kürten, product manager in charge of Doppstadt's shredding division. "We have expanded the range of precision chippers by two solutions that suit the market needs. The tracked DH 811 K for forest and farmland applications, and the DH 910 SA-B chipper with semi-trailer chassis for semi-stationary use, produce a maximum output of high quality products in next to no time."
More power, longer service life and a magnet that attracts everything to it: Doppstadt improves the DZ 750 universal shredder
Doppstadt is now offering its DZ 750 Combi universal shredder with even more powerful components. This combination shredder is designed to handle even the most demanding applications, and now not only has a new, efficient drive unit, but also an even higher metal separation rate and an intelligent hydraulic control system. Its new Volvo Penta engine provides around 700 HP for pre-shredding and supplementary shredding tasks. This machine really comes into its own when shredding heavily contaminated material. The slow-running pre-shredding process efficiently breaks down the material so that the new main magnet can easily separate out any large iron parts. The fast-running supplementary shredding process then produces a marketable end product. Thanks to its 1,000 litre diesel tank, this machine can even cope with long days of continuous operation.
Doppstadt's new DW 308 Rhino is the largest in its class, and is built to shred everything that gets in its way. The DW 308 Rhino will process waste from industry, commerce and households, including C&D waste, organic waste and railway sleepers, as well as green waste, logs and roots. An ideal application is for processing in plants with high throughput capacities. This machine reduces material size reliably and prepares material for further use/recovery. Except concrete, steel and iron, the DW 308 Rhino can cope with virtually any kind of material.
At the recycling yard, compost plant or for agricultural contracting: the new Doppstadt AK 310 EcoPower shredder is at home everywhere. It processes preshredded trunks, roots and waste wood just as reliably as green waste or organic waste, and is great for substrate processing for turnips, potatoes and dung. The compact, versatile shredder (total weight 16 tonnes) is designed for on-road use and is brought to the work site by truck. On site, it can be moved around by wheel loader - even when there is not much space. The machine is fed by wheel loader, excavator or the front loader on the tractor.
At the start of October, the environmental technology company Doppstadt will be launching its new mobile shredder solutions — the AK 560 and AK 635 EcoPower shredders, with the latest technical updates and a new rear conveyor option. Doppstadt's AK 635 comes with an eight-meter rear conveyor as standard, and the AK 560 can be fitted with a six-meter rear conveyor.
Earlier this year, Doppstadt introduced patented self-cleaning screening stars for star screen plants. With this new method to clean star screen machines during operation (machines needn’t stop for cleaning operations) even wet material can be screened without interruption and materials that may stick to the cleaning stars can easily be patted off. The most interesting feature of this system, according to Doppstadt, is that the cleaning procedure does not require any additional equipment: the machine actually cleans itself.
Full-line supplier Doppstadt has announced the completion of the company's full product range for separation technology. Developed in partnership with Anlagenbau Günther GmbH, the new Splittler X2 is a unique technology designed to separate up to three different material streams. Spiral shafts discharge heavy and cubical materials to one side, light and long pieces "swim" on top and are discharged in running direction, while smaller pieces fall through the shafts. Depending on the material, plugging and wrapping are not factors.
