WASHINGTON - A fast-growing project which sees yarn being spun from polymers derived from plastic bottles which have been collected alongside the catch of hundreds of Spanish fishing boats was recently invited to present its work to US Secretary of State John Kerry as part of a Washington-based conference aimed to raising awareness about the environmental damage being done to the world's oceans. The Up-cycling the Oceans initiative of Madrid-based Ecoalf sees Spanish fishing boats in the Mediterranean collecting deep sea plastic waste alongside their daily catch to ultimately produce apparel.
