Glulam wood sleepers manufacturing from recycling discharge sleepers: An engineering recycling project
Abstract
Feasibility was studied for the manufacture of glulam sleepers using wood sleepers that had been discharged or sold at low prices by railway companies. In principle, an engineering recycling project of this nature could contribute to the reduction of non-renewable natural resource extraction. The manufacturing stages of glulam recycled wood sleepers are shown. Ultrasonic tests were used for the classification of the wood sleepers’ parts and wood strength optimization. The results showed that it was possible to obtain one wood sleeper from the recycling of four or five used sleepers.
