Beverage bottles made of glass have again become increasingly popular in the last few years. Lots of consumers and beverage brands are now consciously opting for this type of packaging. A good number of bottlers are thus adding glass containers to their portfolio or expanding their production capacities. They are often then faced with the question of whether to invest in a new system or convert an existing one. Mineral water bottling plant Bad Meinberger was no exception here. They modified the plant’s existing returnable PET line so that it can process glass bottles just as efficiently – and in doing so optimized its consumption values to boot. At the same time the beverage producer invested in the powerful Innofill DRS filler.

In Germany’s Westphalia, the Bad Meinberger brand is drunk at the dinner table, after sport and during work breaks. Besides the popular regional brand for North Rhine-Westphalia, the traditional family-owned company also markets calcium-rich FORSTETAL600 Calciumquelle mineral water, particularly in the north and east of Germany.

Speaking about the bottling plant’s philosophy on quality, managing director Volker Schlingmann says, “Our mineral water is a natural product that we make high-quality demands of. The packaging has to meet these, too.”

What Schlingmann finds particularly important is the concept of environmental protection and the circular economy. The mineral water bottling plant, therefore, pursues an ambitious sustainability strategy that incorporates every single aspect of the company – such as the choice of packaging and the machine technology. For this reason, Bad Meinberger only uses returnable bottles that are ecologically advantageous. Since May 2021 both the company and all Bad Meinberger products have been climate neutral throughout the entire product life cycle. For its outstanding commitment to sustainability, in 2019 the mineral water bottling plant was heralded as a pacesetter at the KlimaEXPO.NRW exhibition.

Convincing KHS service and line performance

Until recently, Bad Meinberger filled its products on two lines – a returnable PET and a glass bottle line. However, the increased demand for mineral water and soft drinks in glass bottles called for a radical restructuring. “We’ve been seeing massive growth in this segment since 2013. In the long term, we saw no alternative but to increase our glass capacities,” says Schlingmann.

The question was whether the plant needed to invest in a new line or whether one of its existing lines could be revamped so that it could cope with the higher demand. Bad Meinberger then approached KHS in this matter. Bad Meinberger decided to turn its existing returnable PET line into a combined system that can process both PET and glass bottles.

The good condition of the machine park had a considerable impact on the nature of the decision reached, with some of the KHS machines in use for over 15 years. The fact that Bad Meinberger also attaches great importance to having trained expert personnel regularly service and clean its plant engineering also paid off in this respect. In 2019 the project then entered the concrete planning and offer phase, for the strategy adopted by the Dortmund systems provider had proved convincing.

Challenging conversion

The conversion focused on the KHS Innoclean EM bottle washer that has been in successful operation for 17 years at Bad Meinberger. The KHS team changed the machine so that it can now sanitize both PET and glass bottles.

This was a very challenging undertaking, Dünnhaupt claims. “The cleaning processes for the two containers differ greatly. There’s a difference in temperature for a start, as glass bottles are washed at considerably higher temperatures. Furthermore, with PET bottles the label has to be cut off before rinsing; with glass bottles, the machine washes the label off.”

KHS duly mastered both challenges through smart optimization of the Innoclean EM. Firstly, it developed a special procedure that makes the recooling and heating process during container changeover more efficient and sustainable. This greatly improves the consumption values on the bottle washer. Secondly, the KHS team also engineered a system for label discharge. Thirdly, the spray pumps were optimized. They now only run at full power when there are bottles in the machine. During downtime or breaks the spray pump pressure levels are automatically lowered. This helps Bad Meinberger to save on water and electricity.

In addition to the bottle washer, the plant’s packers and unpackers in the Innopack PPZ series were also adapted to the new setup. The KHS experts fitted the packaging machines with new format sets and packing heads so that they can now cater for the different bottle and crate formats for PET and glass.

Increased efficiency and improved hygiene

Bad Meinberger invested in KHS’ Innofill DRS filling system. “Converting the machine over to a combined system meant that this new investment was unavoidable,” Dünnhaupt says. “As glass bottles don’t have a cap ring-like PET containers, the filler can’t grip them by the bottleneck. This means they have to be conveyed by the base, a feature the old machine didn’t have.”

The former model was outdated compared to the DRS when it comes to the efficient use of resources. The filler’s high level of hygiene was another key factor that triggered the decision to opt for this particular system. This is facilitated by the machine’s rotary design and installation of the motors in the frame. The automatic CIP caps also play a role here.

The modernized system went into production in the middle of March 2021. The line fills and processes up to 30,000 returnable 1.0-liter PET bottles or a maximum of 33,000 0.75-liter glass bottles per hour. Schlingmann didn’t take it for granted that the conversion would run so smoothly and without any delays. He believes that his company is now perfectly set up for the future with its sophisticated conversions and new investment. The mineral water bottling plant not only profits from more flexibility that allows it to react quickly to changing market demands; its improved line and resource efficiency also helps it to achieve its ambitious sustainability targets.
