Why are heavy trucks considered valuable even after they reach the end of their service life?

Heavy trucks contain large amounts of recyclable materials, including steel, aluminum, copper, and other metals that can be recovered and used again in manufacturing. In addition, some components—such as transmissions, differentials, wheels, or engines—may be suitable for refurbishment or reuse if they remain in good condition. Recycling end-of-life trucks helps reduce the demand for newly mined raw materials, lowers the amount of waste sent to landfill, and supports a more sustainable approach to managing commercial vehicles. It also demonstrates how valuable resources can continue to be used long after a truck is no longer roadworthy.
