The development of a fossil-free textile chain: the revival of plant-based dyes   (KB-45-005-013)

In this project we will take one dye as an example and compare the
technological, environmental and economic impact of production
pathways for fossil-based versus its bio-based options. The results will
be communicated to the textile industry and other stakeholders to
enable fair comparisons, taking true pricing into account.
The ultimate goal is to create awareness of the problems associated
with fossil-based dye production and stimulate the implementation of
bio-based dyes (produced by plants and/or micro-organisms) in the
textile industry.

 

In the 2022 Wildcard project “Dyes for textiles” the plant species
Indigofera tinctoria was identified as one of the most promising crops
to provide a high-value bio-based dye to be used in a fossil-free,
circular textile chain. We will compare the fossil-based and bio-based
pathways for the production of indigo to determine CO2 capture
potential and determine the most sustainable process and value chain.
