The Saint-Martin transport and equipment company LETS presented on Friday June 19 its new mobile impact crusher, a machine capable of transforming construction and demolition concrete waste into reusable gravel for use as a sub-base on roads and for embankments.
The idea stemmed from “a problem,” explains Diego Lake, manager of LETS. Faced with large volumes of rubble during a demolition project, he wondered: “Why not reuse these materials already on site instead of going to the quarry?” After some research, in 2024 he discovered the MR 100 crusher from the German manufacturer Kleemann. More compact and lighter than other models, the machine is well-suited to the island’s narrow roads.
Largely automated, the crusher separates concrete from metal reinforcement using a magnetic conveyor belt and extracts up to 90% of plastic waste via an air separator. This allows for the recovery of a significant portion of construction and demolition waste. The resulting gravel is calibrated to the desired size and then reused in industry, subject to validation by a specialized laboratory in Guadeloupe.
An economical and ecological solution
Costing approximately €610.000 in total, including transport, the machine was acquired thanks to European Union funding covering 65% of the investment. Received in August 2025, this equipment was quickly put to use. Upon its arrival, it enabled the recycling of nearly 900 tons of materials on a construction site. The rubble produced was notably used for the resurfacing of the runway at the Verde SXM Ecosite in Cul-de-Sac.
Capable of processing between 90 and 120 tons of material per hour, depending on its type, the crusher is a valuable tool for an island facing numerous demolition and reconstruction projects. Saint-Martin was the first overseas territory to equip itself with this technology. According to Diego Lake, it’s a way to “save time, money, and protect the environment,” reminding everyone that “our beautiful island isn’t expandable.” _DR
