10,000 employees worldwide, annual sales of almost two billion Euros – the HARTMANN Group is a provider of medical and hygienic products throughout Europe. The focal points are wound treatment, incontinence care and infection protection. PAUL HARTMANN AG in Heidenheim is the heart of the group of companies. It goes back to a textile factory founded in 1818 and is therefore one of the oldest German industrial enterprises. The company‘s homecare logistics are centralized in Heidenheim – the dispatch of small quantities to customers in Germany.
A lot of packaging material is produced in Heidenheim when goods are picked for orders: 260 tons of cardboard and 60 tons of PE per year. Initially, this waste material was disposed of loose in 40-cubic meter containers, brought to an intermediary dealer and compressed there. The marketing revenues were modest. For Michael Kormann, Head of Homecare Logistics and Kornelia Bischof, Waste Management Officer, it soon became clear that the organisation of this process, which is both wasteful in transport and only produced modest results, could be improved. The obvious idea: in the future, HARTMANN wanted to compress the waste themselves in order to achieve proper revenues.
Those responsible at HARTMANN looked at several suppliers of baling presses and also put a machine to the test. The problem: this press could only produce bales of up to 200 kilograms. “This was not enough for the paper factory,” reports Kornelia Bischof. The pilot operation was terminated. After a longer selection process, Michael Kormann and Kornelia Bischof decided on presses from HSM. “The products make a very good impression,” reports Michael Kormann. Operability, soundness, high reliability and thus low maintenance costs with a long service life were the decisive factors in choosing the baling presses from the medium-sized company from Lake Constance. Those responsible at HARTMANN also had confidence that the service pathways were short at HSM. Michael Kormann: “The purchase price is only one aspect, for us the service also has to be right during the operating phase and the systems have to operate cost-effi ciently in the long term. We considered HSM to be best placed to fulfil this.”
At the beginning of the new era in the waste recycling of Homecare Logistics, the vertical baler HSM V-Press 860 S was used for the compressing of polyethylene films into the smallest space. This machine was selected for the trial phase at PAUL HARTMANN AG.
In collaboration with the HSM Sales team, this vertical baling press was adapted to the requirements of HARTMANN: it was provided with – for HSM a fi rst – a sliding door – instead of the sideways opening door provided as standard. The persons responsible at HARTMANN also liked an unique feature of the vertical machine: the compressing process starts automatically when the door is closed and the door opens automatically after the end of the compression. Moreover, since the customer receiving the PE bales from PAUL HARTMANN AG did not want any wire strapping, the HSM V-Press 860 S was equipped with polyester strapping for the first time. Additional eff ect: seventy-five percent lower costs for strapping material. Michael Kormann: “The machine was adapted to our needs and the innovations worked well.” The result of the test was therefore positive. The HSM V-Press 860 S is compact, requires little fl oor space and produces easily marketable bales weighing around 400 kilograms, although loose PE films are fed in, which is praised by Kormann.
After the company from Heidenheim had a good experience with the vertical baling press from HSM, the way was then open for marketing the much more extensive cardboard material with HSM‘s support. Here too, the customer and HSM designed a solution that deviated from HARTMANN‘s original plans. Additional systems such as a tipping device for a 1.1 cubic meter emptying container as well as a conveyor belt for the feeding were readily agreed on. However, HSM advised the customer not to install a fully automatic baling press, including automatic bale wiring, in Heidenheim. For an obvious reason: the volume of 260 tons per year does not justify a fully automatic system in Heidenheim. Since a staff member would be manually feeding the cardboard waste into the machine, HSM proposed that this person could also manually bind the bales with wire. The persons responsible from HARTMANN liked this unselfish advice made from the viewpoint of the customer. Michael Kormann: “In the end, we decided to use the HSM HL 4812 semi-automatic baling press – this is the ideal solution for functional and commercial reasons.” Now, each cardboard bale is manually strapped with four wires in Homecare Logistics. Kormann: “that works fast and well.”
Currently for about three hours a day, an employee is employed in the Homecare Logistics department to press both waste fractions and prepare them for dispatch. HSM advantage: if one machine fails, the other machine can also take over the fraction and compress it. Every six weeks a truck fetches the bales – it can load just under 60 of the 400 kilo packages.
The customers for the bales are happy with the new raw material from Heidenheim, reports Michael Kormann: “Correctly sorted, unsoiled, of constant quality and optimally compacted – we supply dream bales.” It is also ideal that the old cardboard is delivered to the paper factory that produces the cardboard boxes for PAUL HARTMANN AG. This reduces purchasing costs and transport costs – “an almost perfect recycling material loop,” says Korman.
