About Us The L’Anse, Michigan facility works as a contractor to the L’Anse Warden Electric Company (LWEC). LWEC supplies electric power to DTE Energy under a power purchase agreement for renewable energy. L'Anse operators unload scrap rail ties from railcars delivered by Canadian National Railway Company. The end-of-life ties are then ground into a chipped material. The team uses this material to supply chipped crossties and CDF (crosstie derived fuel) for additional uses.
