How do you actually vaccuum - in a circuit?

The circular economy is a hot topic throughout the industry. A good example is plastics processing. The trend here is clearly towards using larger proportions of recyclates, with a distinction being made between PIR and PPR (post-industrial recyclate and post-consumer recyclate).

Ruwac vacuum cleaners come into play with PIR. The operator uses them to suck up production residues, which can then be fed back into the production process.

The circular economy can be realised in a similar way in powder coating, for example, and in many other production processes. The prerequisite is pure suction material without impurities.

Ruwac's chip vacuum cleaner

In metalworking (turning, milling, drilling...), Ruwac chip extractors also ensure that the internal material cycle is closed - but in a slightly different way. They process the mixture of cooling lubricant and metal swarf in such a way that the swarf can be retained in a swarf basket, for example, and 100% of it can be reused, while the liquid components are fed into the processing system.

Ruwac's extraction systems

In some cases, Ruwac also realises extraction systems with material diverters, which can be used to either dispose of the extracted material (e.g. when cleaning the area around grain silos) or return it to the process (e.g. when grain is conveyed and the material is overflowed with the same type of material).

All of these applications are tried and tested. They are documented: Ruwac vacuum cleaners contribute in many areas to transforming the previously linear production and utilisation process (raw material extraction, material processing, product manufacturing, product utilisation and disposal) into a circular economy. In short, they close the loop and enable resources to be reused.
