Po Zu is a British company, which produces leather and vegan shoes in Portugal. All leather is chromium free, tanned in Portugal. Po-Zu states that it recognizes the harmful impact of leather production and develops designs without use of leather. Therefore - apart from using GOTS certified organic cotton - recently, the company has started manufacturing shoes using Pinatex, a new pineapple fibre. Coconut husk and locally sourced cork is used for insoles while natural latex is used as a glue. Po-Zu’s shoebox was nominated for the UK Green Awards 2006, for best packaging. The biodegradable coconut box can be used as trays to grow seeds. As the plant grows, the entire packaging can be planted into the earth where it will decompose and turn into earth once again. Made from 60% coconut husk, and 40% natural latex.
