As part of Nikolett Madai's master thesis, a partnership with bJuice was formulated to research about whether their cold pressed juice processing by-products could contain valuable dye pigments and could it be turned into natural textile dyes, while creating a framework for scalable food by-product sourcing. There were three mixed content types (green, red and orange) and one single pressed food by-product: turmeric. The mixed content underwent an extra step of blending to compress the volume to extract a higher content of pigments, which resulted in various brown tones applied onto calico cotton. The turmeric peels had high yellow pigment content, where this process step was unnecessary.
