Piñatex
Piñatex is the trade name for a non-biodegradable leather alternative made from cellulose fibres extracted from pineapple leaves, PLA, and petroleum-based resin. Piñatex was developed by Carmen Hijosa and first presented at the PhD graduate exhibition at the Royal College of Art, London. Piñatex is manufactured and distributed by Hijosa's company Ananas Anam Ltd.
Development
Piñatex's development began when Hijosa was working as consultant in the leather goods industry in the Philippines in the 1990s. She observed the leather produced there was poor quality, environmentally unsustainable and involved a hazardous production process for those working in the industry. Hijosa was inspired by the barong tagalog, a traditional Philippine garment worn untucked over an undershirt and made of pineapple fibers. She then spent seven years developing the product through a PhD at the Royal College of Art in London, and joint collaborations with Bangor University in Wales, Northampton Leather Technology Center, Leitat Technological Centre in Spain, alongside NonWoven Philippines Inc. in Manila, and Bonditex S.A., a textile finishing company in Spain.Production
Piñatex is created by felting the long fibres from pineapple leaves together to create a non-woven substrate, with the addition of PLA, a vegetable-based plastic material derived from cornstarch, resulting in a base material of 80% pineapple leaf fibre and 20% PLA. The material is then coated with a petroleum-based resin.The production process uses waste pineapple leaves, as the pineapple industry globally produces 40,000 tonnes of waste leaves each year, which are usually left to rot or are burned. Approximately 480 leaves are needed to create of material. The material uses the long leaf fibres which are separated by the pineapple farmers for additional income, the leftover biomass from the process can be used as a fertiliser. The production of Piñatex uses no additional water, pesticides or fertilizers, and avoids the use of heavy metallic salts used in the production of chrome-tanned leather.
