Industrial effluents

Paper industry

The paper-making process is one of the most water-intensive industrial production processes. This is because, without the physical properties of water, it would not be possible for a consistent structure to be achieved when the constituents of paper are processed in sludge. A high level of water consumption is inevitable in the processing of natural raw materials (wood, cellulose, vegetable fibers) and also in the process of recycling waste paper. This creates a high level of waste water for processing. The residues in the waste water are a problem particularly in the case of de-inking: the process of recycling printed waste paper.

Feeding the future: The power of freeze-drying innovation

Waste reduction is important to us at GEA, and by harnessing the power of freeze drying technology, we can transform surplus food into valuable, long-lasting products – helping to reduce waste, extend shelf life and build a more resilient food supply for generations to come.

GEA and Pulmuone honor generations of cold noodle craftsmanship

When plant-forward South Korean food producer Pulmuone brought GEA the challenge of developing a modern spin on the traditional chewy cold (naengmyeon) noodle, GEA’s R&D experts were up to the challenge. They helped develop what is now a commercial hit produced with less water and electricity than previously existing methods. The result is also true to the traditional origins of the dish as well as Pulmuone’s health, well-being and sustainability roots.

GEA's water warriors

In the global campaign for water security, GEA water-conserving and water treatment solutions are driving the effort to reduce water use, waste and pollution – one factory, one farm and one city at a time.
