A process for treating wood, particularly wood wastes (such as sawdust and the like), and/or paper, particularly waste paper (such as newsprint), and/or other types of polysaccharides (matter composed essentially of cellulose and lignin), preferably available as "wastes", with concentrated sulfuric acid (93 to 98.5 % H2SO4), or with concentrated phosphoric acid (75 to 85 % H3PO4), or various mixtures of these acids in their concentrated forms. The product of the process can be used for treating agricultural soils or as a landfill.
