MARPOL liquids
MARPOL (marine pollution) oils are effectively all oils that are produced as a waste product during a ship’s operation. In practice, MARPOL oils are primarily those that contaminate bilgewater or tank wash water. MARPOL oils can, however, be reused as fuel following a simple treatment process.
Environmentally friendly treatment
GEA offers the decanter and self-cleaning separator technologies that effectively separate the waste into water, solids and oils.Using our technology, disposal companies in ports benefit from an efficient treatment that turns a waste product into a sought-after raw material.
Separated oils with a high calorific value
Using GEA decanter centrifuges to separate the MARPOL oil can generally reduce the solids content down to 0.2 per cent, and the content of free water to less than 1 percent. Downstream of this initial decanter separation, GEA separators remove the finest solids and the residual water. The separated oil can then be sold as a fuel with a high calorific value. Recycling the oils also reduces disposal costs. The separated water phase can be treated further in a waste water plant, but it is clean enough to be returned straight to the environment.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Decanter Centrifuge
The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...

From fossil fuels to future-ready: The rise of heat pumps
While the initial interest in heat pumps was to save on operating costs, reducing emissions is now the main driver for the technology. Learn more about how GEA is spearheading efforts to increase energy efficiency and reduce CO2 emissions through hidden champion heat pump technology for industrial and district heating sectors.
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.
