The Basel Convention website8 provides data on transboundary movement of hazardous waste and other waste (i.e. household waste and incinerator ash from household waste) and this could be a starting point to understand the trends and magnitude of such trade flows.9 Correspondence tables between waste codes and the Harmonised System (HS)10 are also made available by the Secretariat of the Basel Convention (2013) as well as individual studies by Kellenberg (2012), which enables to complement data on international trade flows of waste. Preliminary results show that global trade in waste and scrap reached 227 million tonnes in weight and USD 96 billion in value in 2016. Over the period of 2003 to 2016, the amount of trade increased by 48% in weight and 183% in value. These trends imply that the value of waste and scrap has significantly increased during the past decade. The majority of these trade flows consisted of metal, paper and plastic waste and scrap which all together accounted for 97% in total value and 94% in total weight in 2016 (Figure 2).
