Plastic waste management is one of the major environmental concerns in the world. Plastics can be separated into two types. The first type is thermoplastic, which can be melted for recycling in the plastic industry, such as polyethyleneterephthalate (PET). The second type is thermosetting plastic. This plastic cannot be melted by heating (such as melamine). At present, these plastic wastes are disposed by either burning or burying. Therefore, both the ways contributing to the environmental problems. This paper describes the use of thermosetting plastic waste as aggregate within lightweight concrete for building application and possibilities for re-use of thermosetting plastic waste in the concrete are described in detail.
