Abstract

The present invention relates to a process for retting fibrous biomass to release cellulosic fibers present therein. The process comprises digesting the fibrous biomass in at least one bio-digestive step by use of anaerobic digestive bacteria to release the cellulosic fibers. In the bio-digestive step, a retting aqueous liquor comprising anaerobic digestive bacteria is supplied to packed fresh fibrous biomass. The packed fresh fibrous biomass to be digested in the biomass bio-digestive step has a degree of packing corresponding to a density in dry state of 135 kg/m 3to 450 kg/m3. Alternatively the cellulosic fibers released in the bio-digestive step are treated with an aqueous composition in a post retting, fiber refining step at a temperature of at least 60°C.
