Análisis del Ciclo de Vida de los Procesos de Recubrimiento Metálico de Termoplásticos

This study focuses on the evaluation of the environmental impact of the most common industrial processes used in metallic coating processes of thermoplastics. Among these, conductive painting, chemical metal deposition and high-vacuum metal deposition are considered. The methodology used was the Life Cycle Assessment methodology. The results show that conductive coating painting has the greatest environmental impact, especially due to the emission of volatile organic compounds. High-vacuum metal deposition exhibits the best environmental performance, with minimal raw material and energy consumptions throughout the process. However, the high cost associated with the purchase of the required equipment for the high vacuum technique have made conductive coating painting the most commonly used process.

Analysis of the process applied to end‐of‐life vehicles in Authorised Treatment Facilities

Authorised treatment facilities (ATFs) play a key role in the process undergone by vehicles when they reach their end of life (EoL) within the context of Directive 2000/53/EC. Whenever an EoL vehicle is received at an ATF, a certificate of destruction is issued. The process continues with the depollution of hazardous waste materials from the vehicle and dismantling of parts that will be reused or recycled. Finally, the remaining parts of the vehicle are transported to a shredding plant.Directive 2000/53/EC sets a number of environmental goals regarding the reuse and recycling of vehicle parts and the recovery of waste materials at the EoL of vehicles. These goals will condition the evolution of ATFs as they gradually become more restrictive.As of today, the goals set by Directive 2000/53/EC for the year 2006 are being met (1). However, it would be necessary to assess the situation of those parts that comprise the fraction of the vehicle that is not recycled, reused or recovered in order to predict the deg...
