The INTI study has identified a sustainable process for creating water-soluble natural dyes that may be dry-stored
Researchers at the Argentine National Institute for Industrial Technology (INTI) are taking a new approach to the manufacture of natural dyes from agricultural waste. The method involves extraction of pigments from waste and conserving them in dust form, meaning they can be dry stored for use all year round. Over the past year numerous agricultural materials have been tested with one of the most promising candidates being peanut shells – one of Argentina's main exports.
