Abstract:

This paper gives an overview about Pulp and Paper Industry (PPI) residues, their properties and some solutions for converting those materials into fuels. The main leftovers are bark, sludge of aerobic digestion, primary floto sediment (PFS) and pulp rejects (PR). PFS and PR after applying dewatering (press fluids) have considerable biogas potential. Bark and press cake of PR are a good resource for briquetting. Ethanol potentials of bark and PR cake are presented.
