Study for the development of natural dyes from local crops with dyeing properties in a Circular Economy perspective


The research project analyses local crops of dyeing plants to assess the potential for developing natural dyes for industrial use. The research, in a Circular Economy perspective, proposes a series of strategies to valorise the by-products derived from the extraction processes of the crops analysed.


The results of the study led to the experimentation of natural dyes derived from two dyeing plants (woad and madder), applied in different industrial fields. At the same time, proposals for new applications were defined to develop circular business models from the industrial by-products of the two sectors.
