Zero Sludge

Using a powerful jet engine to treat wastewater in the production stages in factories, by turning the toxic sludge into more manageable dry powder and extracting clean water to be released or reused.

Awarded: €150,000 Year: 2020 Company: SeaChange Technologies

The innovation in a nutshell

Separating and cleaning wastewater to eliminate toxic sludge in landfills.

Let us explain

For many people, new seasons mean new colour trends. But before the latest fashion piece caught your attention, it likely went through an extensive dyeing and finishing process at the factory, an undertaking that emits great volumes of greenhouse gases and pollutes the water. And that’s not the end of it. You see, polluted water turns into a thick toxic sludge that is tough to handle. Every day, the apparel industry generates hundreds of tonnes of murky sludge which is often dumped in landfills.

This solution connects a smart gadget to the existing systems. The innovation separates the water from toxins with the help of a powerful jet turbine. The result? Zero sludge! Instead, the toxins are separated into a neat, manageable powder while the clean water is turned into a mist that can be released or reused. Through this process, the carbon footprint is significantly reduced too.

Let’s be colourful, but crystal clear: no more toxic sludge!
