The March-April issue of WSA, which is available here in digital form, leads with an in-depth article examining the possibilities of using algae as a source of fibres, finishes and dyes. The magazine also delves into the world of blockchain to see how this might be able to benefit the textile and apparel industry. Later in this issue, we cover efforts at adidas to enhance sustainability, and look in detail at the Hohenstein Group’s work to analyse the propensity of different fibres and material constructions to cause micro-plastic pollution. Plus, we offer a full review of the outdoor footwear innovations that were on show at ISPO 2020 in Munich. Our interview series, Dialogue, continues with a quick-fire question-and-answer session with Anna Maria Rugarli, sustainability director in Europe for VF Corporation, bringing this issue of WSA to a lively close.
