| Abstract |
Rising socioeconomic level and increasing popularity of e-commerce have dramatically increased the use of cardboard packaging materials, and consequent related recycling and wastes. Large amounts of sludge (up to 40% of input mass) is formed through the recycling process, with sludge solids that are very rich in cellulose fibers (similar to 75% w/w). To date this sludge is mostly disposed in landfills, resulting in added economic and environmental costs to the recycling process. Short ozonation pretreatment of RPS resulted in enzymatic release of similar to 34% of the cellulosic fraction of the sludge as sugar, and fermentation of these sugars by yeasts resulted in production of similar to 15 g/L ethanol. The solid remnants, were used as a bio-sorbent, efficiently removing dyes from textile wastewater. Recycled paper sludge waste was thus a good source for both energy and water-treatment applications, increasing sustainability and circular economy in the paper and cardboard recycling industry. |
