ANALYSIS OF WASTE FLOWS USING WIO TABLE
Keywords:IO table, WIO model, waste cycle analysis.
AbstractAs industrial sectors and waste management sectors are related to each other in IO table, this paper aims to inventory waste cycles among the sectors in Vietnam using IO (Input – Output) table and WIO (Waste Input - Output) model. The national published data of 164 product sectors are based on the 2012 IO table updated for 2016. The material flows that each sector contributes to the others are quantified and then combined with the corresponding waste generation coefficient to determine the load of waste generated, collected and treated for each sector. The investigated data include quantity and composition of hazardous and solid waste handled by 200 waste treatment facilities in 2016. The type of waste is limited to 3 categories including wastewater, domestic and normal industrial waste, and hazardous waste. The research drives towards to build an economic mathematical model for Vietnam that gives a quantified analysis of waste flows.
