摘要：Sunglasses were created after the First World War and, since then, have been used by great part of the population, as an accessory and as eye protection. To investigate the end of the life cycle of this product, an on-line questionnaire was devised and 765 answers were collected from users. In addition, interviews in eyewear stores and repair shops were realized. Based on the gathered data, two sunglasses models were selected to analyse their recyclability potential: model A, made from thermoplastic and model B, made from wood. The frames were analysed under the Design for Dismantling and Design for Recycling approach. The material characterization for model A was necessary, made through the FT-IR technique. The analysis shows that model A has lower impact when dismantling, separating and reusing materials through mechanic recycling technology. Although model B is made of materials from renewable resources (wood), the frame production by pressing with epoxy resin compromises the separation of post-consumer waste, which, in this case, is indicated for reuse through energy recycling.
