B+T uses Lindner shredders to supply Deuna Zement GmbH with energy
The two major players in recycling and waste processing: Lindner-Recyclingtech and the B+T Group have been partners for many years, successfully working together on many important projects. Now they are delighted to announce their latest project: a brand-new SRF production facility with the most modern technology in the whole of Germany. Developed and operated by the B+T Group, the facility is located on the premises of Deuna Zement GmbH and supplies the cement production plant – important in the Thuringia region and beyond – with fuel from sorted and commercial waste in optimum, homogenous quality – 24/7, 365 days a year. One Lindner Jupiter 3200 for primary shredding and three Komet 2800 HP for secondary shredding are in operation there. The latter are part of the new Series 2 – a recently launched Lindner innovation.
Spittal an der Drau/Austria and Deuna/Germany, August 2019. Following the ground-breaking ceremony in mid-2017, regular operations could begin at the large facility as early as April 2018 – an incredible team effort by B+T and Lindner that was duly celebrated with a festive inauguration in September 2018.
The challenge: a complete processing line just in time
When installing the shredding and sorting technology, it was of paramount importance to avoid disrupting operations at the adjoining cement plant as much as possible. Since the rotary kilns have to be fed constantly, the best time for the installation was during the overhaul phase, when maintenance and repair work is carried out. An ambitious target that was successfully achieved thanks to systematic planning and perfectly timed implementation.
One of Europe’s most modern plants: the B+T Group’s SRF production facility in Deuna
The Bohn group’s eighth facility – with a total of over twenty Lindner machines in operation – covers an area of 25,000 square metres below the cement plant, has a maximum throughput of 250,000 metric tons per year and a storage facility for approximately 4,000 metric tons of finished goods. Pre-sorted waste is processed at the plant, especially non-recyclable post-consumer packaging and plastic film, as well as rubber and textile waste, which also cannot be mechanically recovered. With the full supply contract, the newly founded operating company B+T Deuna GmbH has agreed to supply the cement plant 24/7, 365 days a year. For quality assurance purposes, the solid recovered fuel is constantly tested for its burning properties using near-infrared technology (NIR). PVC with chlorine has no place in fuel and is safely removed.
Likewise, the calorific value and humidity are permanently monitored. The dosage is adjusted in real time and independently of external laboratories, guaranteeing continuously optimum fuel quality.
However, Deuna has not only invested in modern and high-quality engineering: a tour of the production unit, office and ancillary buildings reveals that the best system technology available has also been used for fire protection, establishing reliable safety standards.
The backbone of the facility: the 420-metre-long pipe conveyor
This striking feature enables the premium solid recovered fuels from the SRF production facility to reach their destination in the cement plant: the 420-metre-long pipe conveyor connects both facilities and feeds the rotary kilns directly with the solid recovered fuel. It’s also the most remarkable architectural element outdoors. ‘The pipe conveyor is visible from afar – and rightly so, because it’s the facility’s backbone,’ explains Matthias Pitz, the B+T Group’s CTO. Together with Henning Bruns in the team of experts, he is responsible for the design, planning, construction and monitoring of the Deuna plant.
