Abstract: | The aim of this study is to investigate waste streams as a source of recyclable raw material for fiber composite production. Globally, vast volumes of waste are produced daily that are not recycled effectively. In this work, three different raw material sources are examined; industrial, construction and municipal solid waste streams. All three sources produce wastes that are currently underutilized. Usage areas for the waste material include use as a reinforcing fiber, as part of the plastic matrix or as a filler. The industrial sector produces more homogenous waste, while waste from municipalities is mixed. Irregular material flow, the varying condition of the waste and different pretreatments used pose difficulties for recycling. Furthermore, some materials are industry-specific and may be produced in only certain areas. Despite these difficulties, huge amount of potentially useful exploitable waste is available and using different waste streams as a part of wood-plastic composite production can reduce waste volumes disposed to landfill. |
