Abstract

A filter for capturing dyestuff is provided. The filter includes a housing defining an inlet. The housing further includes an outlet spaced from the inlet. The housing further includes a cartridge in fluid communication with the inlet and the outlet. The inlet is adapted to receive effluent including dyestuff and the outlet is adapted to release the effluent. The filter further includes a substrate disposed within the cartridge. The substrate includes an active material. The active material has an affinity for the dyestuff. The dyestuff is present in the effluent at the inlet in a first amount and not present in the effluent at the outlet or present in a second amount with the second amount less than the first amount. The filter is composed of a textile composition made fiber or fabric which can be recycled by mulching back into a dyed fiber upcycling the normally wasted dyestuff, to now be reused in an upcycled dyed textile production. The filter with its reusable cartridge, the substrate which bonds and upcycles waste dyestuff operates in a linear or preferable circular economy.
