While economic and societal pressures have increased the recycling of mixed paper waste within the last decade, such material remains an underutilized, potentially valuable feedstock and source of cellulose. Mixed paper waste containing a combination of shredded coated and uncoated paperboard with shredded printing paper, including glossy advertisements, was explored as a solid-state fermentation (SSF) substrate for the production of cellulase from Trichoderma reesei QM9414. Following 14 days growth at 25�C, cellulase was desorbed from the substrate by agitating in water for 30 minutes, and cellulase activities of the clarified aqueous media were determined by a modified filter paper assay. Cellulase yields were generally lower than those reported for SSF production using various agricultural waste materials. Pretreatment of the mixed paper waste with acid significantly improved the yield of cellulase. Cellulase production using SSF on mixed paper waste provides an alternative use for this type of common municipal material.
