With bottle-to-bottle recycling – the re-use of used PET bottles to produce PET bottles – Krones plants reduce energy use by up to 50%.

 

Rinsing water can be collected using the appropriate means, filtered and reused. The savings that can be achieved with circulation systems for a peracetic acid-based aseptic line with 36,000 bottles per hour are approximately 2.5 m3 sterile water per hour.

 

With the PET Asept D H₂O₂ technology for aseptic filling, our customers achieve high levels of sterilisation in dry disinfection processes. This saves water and sewage as the sterilising agent does not have to be rinsed off with water.

A new alternative to the filtration process with environmentally harmful diatomaceous earth widely used for beers is the membrane technology. A brewery with an output of 1 million hl/year disposes of around 120 t diatomaceous earth each year as waste requiring supervision.

 

Krones Variotherm offers a heating system with plate heat exchangers actually in the bottle-cleaning machine. Compared to the reverse-flow systems generally used, the distinctive feature of these heat exchangers is that their heat transfer coefficient is up to five times better. For the operator, this means that the fuel costs can be cut by up to 10%.

With the Parcival caustic filtration concept – a diaphragm filtration system with self-cleaning disc filters – the tensides in the post-caustic tank are reduced by 50% with the same use of chemicals and water. The result: less disinfectant has to be added.

 

By adapting the Variopac machine design, it was possible to then process the pack with a film with a thickness of 40 µm instead of the previous 65 µm. More packs can thus be produced from one film reel.

In palletising technology, the aim is to reduce the noise level by using low-noise components. By using toothed belts, linear guides with a bead chain, plastic guides and CFRP rollers, noise emissions can be reduced to significantly below 82 dB(A).
