An Input–Output Analysis Approach in Waste of Electrical and Electronic Equipments

The disposal of waste of electrical and electronic equipments (WEEE) represents the loss of large amounts of valuable resources, in particular metals and plastics. If these were to be recycled, it would not only divert the waste from disposal by limiting waste flows damage but would also reduce the need to use virgin raw materials. In this study, we focus on waste management and we concentrate on the recycling of mobile phones. Mobile phone components and their requirements in production phases such as energy, labor, and know-how are depicted in a matrix form inspired from the seminal work of Leontief and input–output (I–O) methodology which appears to be appropriate for analyzing waste management problem is presented. Thus, we propose numerically static I–O solutions in order to demonstrate the contribution of recycling of mobile phones into the economy. Particularly, we concentrate on the monetary IO table (MIOT) and environmental IO table (EIOT) with recycling and balance equations. By defining waste outputs as a new vector class, the classical I–O model has been improved.
