End-of-life product-specific material flow analysis. Application to aluminum coming from end-of-life commercial vehicles in Europe

Although separate collection systems for portable batteries (PBs) have been installed years ago, high amounts of batteries still do not enter the collection systems of the member states of the European Union (EU). In Austria, the collection rate has recently dropped to the EU target value of 45%. For the purposes of this study, a comprehensive survey was conducted to identify the destinations of the other end-of-life batteries. A literature survey and an assessment of different waste streams (WSs) were followed by sampling and sorting campaigns for highly relevant WSs (residual waste, lightweight packaging waste, metal packaging waste, and small waste electrical and electronic equipment). The results underwent material flow analysis, showing that more than 800 metric tonnes of portable batteries are misplaced into non-battery-specific collection systems, 718 metric tonnes of them entering residual waste collection. Considerable amounts of batteries are stockpiled, stored or hoarded in Austrian households. Lithium-based batteries, representing a serious risk of fire to the waste industry and making up for 30% of the marketed amount, are still scarcely arriving in waste management systems.

Cathode Ray Tube

Cathode ray tube televisions (TVs) contributes significantly to the rapidly increasing waste stream of cathode ray tubes in the e-waste. This study mainly focused on the material flow of waste cathode ray tube TVs in China. Currently, waste cathode ray tubes constitute a major part of the total generation of e-waste in China. The study aimed to emphasise the flow of materials in the generated waste cathode ray tube TVs by using stock-based material flow analysis model. The modelling was conducted to investigate the disposable number of obsolete devices, in-use stock, and end-of-life of cathode ray tube TVs. SubSTance flow ANalysis (STAN) software was used to perform the material flow analysis modelling and graphical model of the waste cathode ray tube TVs. The results show that in a period of 10 years, overall about 3241.37 kt of cathode ray tube TVs were net produced in China, containing 183.6 kt of glass, 1718.2 kt of plastic, 243 kt of steel/iron, 153.5 kt of lead, 76.6 kt of copper, 7.8 kt of aluminium, and 1.6 kt of antimony. The results revealed that almost 125 kt of end-of-life cathode ray tube TVs containing about 68 kt of glass, 40 kt of plastic, 9 kt of steel/iron, 6 kt of lead, 3 kt of copper, 0.3 kt of aluminium, and 0.07 kt of antimony were dumped in the period of 10 years. Therefore, the management of waste cathode ray tube TVs required better infrastructure for recycling and better regulation to achieve better results in the high recovery of valuable resources.
