The bioelimination of a series of hydrolysed reactive dyes of known chemical structure has been determined using a new, rapid and robust laboratory method and a chemometric analysis conducted on the bioelimination results. The level of bioelimination varies from 0% up to only 25% and the chemometric analysis indicates that if either the number of aromatic rings increases or the number of 2‐hydroxyethylsulphone groups decreases, then the bioelimination increases. To maximise the bioelimination of reactive dyes, large, planar triazine‐based dyes should be used.
