Industrial effluents

Olive oil mills

As a result of their high content of polyphenol, fatty acids and organic substances, effluents from olive oil production are posing an increasing environmental problem. It is true that modern production processes now make a major contribution towards reducing the volume of effluent. Nevertheless, it is still the case that approximately 200 liters of water must be used for each ton of processed olives; this effluent contains oil and extremely fine particles. In order to ensure the environmentally-sound treatment of these effluents, GEA supports industry with innovative technologies which not only considerably reduce the volume of effluent but also enable all residues to be virtually fully recycled, thus creating economic as well as ecological added value.

A new recipe for indulgence

What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.

Fueling the circular economy in shipping

Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
