The LAMESCH company, created in 1962 by Jean Lamesch, is the benchmark in the Grand Duchy of Luxembourg for the collection, sorting, recycling, treatment and elimination of waste as well as for sanitation services. It currently employs more than 600 people at its sites in Bettembourg and Holzthum.

In the 2000s, LAMESCH joined SUEZ then PreZero in 2021.

PreZero is now positioned as one of the world leaders exclusively dedicated to the waste businesses and employs around 13,000 people at 280 sites in Germany, Poland, Sweden, Belgium, the Netherlands, Luxembourg, Austria, Italy and the United States.

By joining PreZero, LAMESCH benefits from the influence of the group which allows it to consolidate its position as leader in waste treatment in Luxembourg. LAMESCH thus applies the experience feedback acquired in order to meet the expectations of its customers.
