Solid bleached sulfate (SBS) paperboard coated with polyethylene terephthalate (PET) is a type of cellulose and hemicellulose based waste from the packaging industry for ready-to-eat foods. In this context, the objective of this study was to evaluate the discoloration of the Remazol Brilliant Blue Reactive (RBBR) dye by bioabsorbent, consisting of ligninolytic macrofungal mycelium supported on PET-coated SBS paper. This work involved three steps: first, to determine the residual concentration of Remazol Reactive Bright Blue (RBBR) dye in the effluent produced in a dyeing process, according to the dye concentrations most applied in the textile industry. In the second step, the solution with medium concentration of the RBBR dye was then treated with the bioabsorbent, composed of ligninolytic macrofungus mycelium supported on PET-coated SBS paper. In the third stage, the technical feasibility of reusing the bioabsorbent was evaluated. The effluent generated from dyeing baths and washes was collected and analyzed, providing a final effluent with an average residual concentration of 57.3 mg/L of dye. The results showed that higher concentrations of carbon and nitrogen gave rise to the bio-adsorbent with higher values of total proteins and enzymatic activity. The bioadsorbent use and reuse tests showed 94% color removal for the RBBR dye over 30 days of reuse. The use of the bio-adsorbent for the decolorization of dyes and textile effluents is a potential efficient and low cost.  aBiodegradation  aDecolorization  aGanoderma lucidum  aPolyethylene  aBiodegradação  aPolietileno  aAzul Brilhante Reativo Remazol  aCorante têxtil  aDescolorização  aEfluente têxtil  aPapel-cartão SBS  aSBS paperboard  aTextile dye  aTextile effluent1 aNUNES, H.
