As a guest on Éric de Riedmatten’s show *L’Hebdo de l’Éco*, Thibault Lamarque, founder of Castalie, sheds light on an issue that is increasingly at the forefront of public debate and within organizations: Should we continue to prioritize bottled mineral water, or should we rethink our consumption habits and turn to tap water?

In his presentation, the entrepreneur advocates an approach based on making the most of locally available resources. In his view, water should no longer be considered solely as a product that is transported and packaged, but as a resource that can be consumed more responsibly thanks to microfiltration technologies. This vision has been at the heart of the model developed by Castalie its founding.

The French company designs microfiltered water solutions for businesses, hotels, and restaurants. Using filtration systems installed directly at the point of consumption, tap water is transformed into high-quality water—still or sparkling—and served in reusable containers. This approach helps reduce the transport of bottles, limit waste, and decrease the use of single-use plastic bottles.

The program also highlights a more profound shift in the expectations of organizations and consumers. Issues surrounding sustainable development and environmental responsibility are leading more and more stakeholders to seek solutions that balance service quality with reducing their environmental impact. Sustainable hydration is thus becoming a concrete driver of the green transition for businesses and professionals in the hospitality and restaurant industry.

By bringing this debate to a business media outlet, Thibault Lamarque is helping to raise awareness among a broad audience about issues related to water consumption and the reduction of plastic waste. This statement reinforces Castalie position Castalie a major player in the microfiltered water market in France and confirms its founder’s reputation as a committed advocate for environmental innovation, ecological transition, and impact entrepreneurship.
