This fact leads to the necessity of finding new uses for residual materials that can be re-used. the paper is a brief review of recent literature on the possibilities of advanced biotechnological solutions to produce alternative energy sources as methane, hydrogen, ethanol and valuable organic products as acetic acid, lactic acid, from pulp and paper solid wastes. the paper also includes the preliminary experimental results obtained for biogas production from paper and mill organic sludge in combination with fermented municipal sludge and cattle manure as inoculum.en-USPaper and millSolid wastesBiotechnological solutionsAlternative energy sourcesArticle
