We have the right compacting solution for your packaging and production waste

Whether empty and dry, or filled and wet

Are you looking for an economical disposal solution for your filled or empty packaging such as cans, plastic bottles, tubular bag packaging, yoghurt pots, or for used labels of glass and PET bottles? Then you will find what you are looking for at WEIMA. We offer you a comprehensive portfolio of compression solutions – all from one source.

WEIMA press working principle

Compact dewatering presses from WEIMA work with a hydraulically movable cylinder instead of a classic compaction screw. This has a decisive advantage: wear and the associated maintenance costs are reduced to a minimum.

Wide range of applications

If you are looking for a high-quality and long-term compaction or drainage solution, there is no way around WEIMA machines. Due to their complete stainless steel construction, they are not only appreciated by breweries, dairies, soft drink producers and bottling plants, but also by operators of biogas plants, plastics processors and food producers.

Machines for compacting or draining – with PÜHLER know-how

With the purchase of the drainage specialist PÜHLER, WEIMA has expanded its competence in the field of compaction. For more than four decades and with more than 6,000 machines on the market, PÜHLER presses have been used in the beverage and food industry for the pressing and recycling of packaging and labels of all kinds.

Rejects can also occur during the production of ketchup, mayonnaise, mustard, remoulade or other sauces. No matter whether it is to be disposed of professionally or reused – the first step is to empty the packaging or container with a WEIMA press.

Benefit from the advantages of an integrated waste disposal concept
That is why a WEIMA press is worth it for you:

Recycling instead of hazardous waste
Until now, rejects, production defects and defective batches have had to be disposed of expensively as hazardous waste because the contents are still in the packaging. This is neither environmentally conscious nor economical. Even if the containers are already emptied by hand, this ties up additional personnel, who have to perform a high proportion of manual work. The solution: WEIMA drainage machines.

Full containers or packs can be fed into the press fully automatically. After the packaging or labels have been emptied and compacted, waste streams are separated according to material and can be disposed of properly.

3-in-1: Empty. Separate. Press.
With a WEIMA press you get the all-inclusive package. Once filled, the machine separates the contents from the packaging in one process step. The packaging itself is compressed. The discs produced are ideally suited for plastic or metal recycling. The contents can be disposed of properly or, if necessary, further processed.

Superior machine design
Especially for applications in food production the prevention of microbial contamination is of central importance. For this reason WEIMA relies on Hygienic Design, which takes into account hygiene-critical specifications for food safety. Thus we rely on machine bodies made of stainless steel, special welding seams to prevent contamination and on a low-maintenance, cleanable overall concept. A fully automatic cleaning system within the machine ensures high machine availability. In addition, we use food-grade oils for WEIMA machines. The machines are HACCP-compliant and can easily be integrated into your Hazard Analysis Critical Control Point (HACCP) concept.

Industry 4.0 ready
At WEIMA you will never get an off-the-shelf machine. Each press delivered is individually configured and handed over to the user as a turnkey, plug-and-play solution. State-of-the-art data interfaces guarantee seamless integration into your production line, so that the machine can be controlled and monitored in fully automatic operation. Another advantage that is only available from WEIMA: As a shredding specialist we also offer upstream and downstream system solutions if required. These include single-shaft and four-shaft shredders, granulators and briquette presses with enormous pressing forces.

We rely on stainless steel

For a long service life, we recommend the particularly high-quality stainless steel machine version. The machine body is thus protected against heavy wear and corrosion like rust. For less abrasive applications we also offer machine versions made of galvanized or painted steel.

Typical reasons for production rejects

  • Under or overfilled packaging
  • Overproduction
  • Incorrect labeling
  • Wrong content or recipe
  • Damaged packaging
  • Rinsing batches after recipe change
  • Returns

If the scrap material is not suitable for further use for hygienic or quality reasons, it does not necessarily have to end up unused in garbage. Rejects are often suitable as a source of energy (incineration or fermentation) or even as fertilizer or feed on farms.

Got milk?

With WEIMA packaging presses even everyday things like milk cartons can be emptied quickly and neatly.
