SciLux podcast – Silvia Venditti on Wastewater Treatment

21 January 2025

The Power of Nature-Based Solutions

With water scarcity becoming an increasing concern, Dr Silvia Venditti has chosen to focus her research on nature-based solutions for the removal of micropollutants from wastewater and the reuse of water.

Dr Silvia Venditti is Research Scientist at the University of Luxembourg, specialised in environmental engineering. Silvia Venditti’s work is at the forefront of sustainable wastewater treatment, focusing on the removal of micropollutants and the reuse of water. Her journey from traditional engineering to embracing nature-based solutions is a testament to the evolving landscape of environmental science.

Listen to Dr Silvia Venditti to find out how research is helping to tackle pollution through nature-based solutions for wastewater treatment.

Environmental Innovation

Nature-based solutions are innovative approaches that mimic natural processes to restore and protect ecosystems. Silvia Venditti involves designing systems that leverage these natural processes to treat wastewater effectively. This method not only addresses pollution but also integrates seamlessly into the environment, offering a sustainable alternative to conventional high-tech solutions.

Nature is the most powerful engineer.

One of the significant challenges Dr Venditti faces is the unpredictability of nature. Unlike machines, nature-based systems can vary in performance, pushing engineers out of their comfort zones. However, this challenge is also an opportunity for interdisciplinary collaboration, bridging the gap between engineering, microbiology, and plant sciences.

Silvia Venditti’s research highlights the potential of nature-based solutions to create a circular economy. By recovering valuable materials like cellulose from wastewater and converting them into biochar, these systems can reduce environmental impact while producing useful by-products. This approach aligns with the European Commission’s push for sustainable practices and could lead to the creation of millions of new jobs globally.

As water scarcity becomes an increasing concern, Silvia Venditti advocates for a shift in mindset towards water reuse. Projects in Luxembourg are already exploring the reuse of treated wastewater for non-potable purposes, such as toilet flushing, demonstrating the practical applications of her research.

A podcast to highlight research made in Luxembourg

Research Luxembourg and SciLux have teamed up to launch a new series of podcasts showcasing science in Luxembourg and beyond.

With a new episode every 2 weeks published, ‘SciLux powered by Research Luxembourg’ will showcase research activities and scientific cooperation in Luxembourg.
