Estudio de métodos de evaluación de la desmontabilidad de productos industriales

Abstract

New European directives are contributing to an increasingly more restrictive environmental legislation. 2000/53/CE directive for End-of-Life Vehicle (ELV) and 2002/96/CEE directive for Electric and Electronic Equipment Waste (WEEE, which has taken effect in July of 2005) stand out because of their novelty and restrictive nature. These directives deal mainly with recycling and reusing of components at their end of life. At their end of life (EOL), products must be disassembled to separate components or useful parts from the ones that are not. Useful parts are reused, remanufactured, recycled or incinerated to obtain energy, whereas the non useful ones are put in rubbish dumps. Design for Disassembling (DFD) searches for component reuse. If this could be achieved for a high percentage of products and parts, the need of waste disposal would be drastically decreased. Nowadays, there are different methods to evaluate the disassemblability of a product (Disassembly evaluation chart, End-of-life environmental impact model, etc.). All of them are based on the estimation of disassembly time. The objective of this communication is to compare these methods to determine which evaluation method is best adapted to each reality.
