On the morning of Friday 25 July 2025, waste management company PreZero inaugurated its new hospital waste treatment facility at its Bettembourg site.
The event, attended by Luxembourg’s Minister of Health and Social Security, Martine Deprez, marked a major step towards Luxembourg achieving waste autonomy, with the new facility able to treat infectious medical waste - ending the need to export the waste for processing.
According to PreZero, the facility was born out of the upheaval caused by the Covid-19 crisis. During this period, the potential closure of borders threatened cross-border transport of certain types of waste, including “infectious” waste that Luxembourg exported for treatment. Without a local solution, this represented a significant health and environmental risk to the country.
“Thanks to the support of PreZero, we were able to invest in this new facility. We are now capable of treating infectious waste locally, while consolidating our environmental approach through a significant reduction in CO₂ emissions and eliminating contamination risks. This machine operates solely on electricity: without water, steam, chemicals, or any atmospheric emissions,” emphasised Yves Feuillen, CEO of PreZero Lamesch.
PreZero announced that the company is responsible for the waste from collection to treatment and reported that upon arrival the waste is first shredded and then subjected to a temperature of 100°C for one hour using microwave technology. At the end of the process, all bacteria and viruses present are destroyed and the waste emerges decontaminated and dry, ready for use in energy recovery processes.
