Abstract

The wooden sleeper has been used at the railway track. Recently the concrete sleeper is pushing the wooden sleeper out, but huge amount of waste wooden sleepers are discharged every year. Due to the contaminant of waste wooden sleeper, its disposal is very difficult. Commonly a wood preservative such as creosote is used in the manufacturing process and it becomes major contaminant after use. And the wooden sleeper is contaminated by diesel from locomotives and lubricant oil from the maintenance of railway turnout. Currently the limitary disposal methods can be used because of high toxicity of waste wooden sleeper. Therefore the preliminary study on thermal-extraction of contaminants such as creosote, diesel and lubricant oil from waste wooden sleeper was conducted and the effects of factors were investigated.
