What is it about?
In this paper, we describe how we developed and adapted a technology to clean air contaminated with solvent vapours in the car paint industry. We used a compact bioreactor with microorganisms that ‘eat’ these compounds, making the air much cleaner before it is released. We first tested the system in the laboratory and then in an actual plant, and found that it could continuously remove up to 99% of the pollution, with low energy consumption and without generating hazardous waste. This demonstrates that it is possible to significantly reduce the environmental impact of automotive painting by using sustainable biological solutions.

Why is it important?
This research is important because it offers a real and proven solution to one of the most common environmental problems in the automotive industry: volatile organic compound emissions during painting. What makes it unique is that it adapts a biological technology, trickle bed biotreatment, to a very specific industrial context, overcoming challenges such as variability in emissions, available space, and the need for continuous operation. Its approach combines laboratory testing with validation under real-world conditions, demonstrating that it is possible to achieve high levels of pollutant removal without resorting to costly processes or those that generate hazardous waste. In this way, it presents a sustainable, scalable, and adaptable alternative that not only improves air quality but also helps companies comply with environmental regulations and reduce their ecological footprint.
Perspectives
The most satisfying aspect of this research was demonstrating that a biological system as simple and elegant as microorganisms could reliably manage complex emissions while seamlessly integrating into existing operations. I hope this work inspires more industries to view biotechnologies not as experimental, but as practical, robust, and ready to make an impact in the real world.
