  • Patent number: 11760961
    Abstract: A novel binder and/or disintegrant for obtaining a compressed solid composition for non-oral use, the binder and/or disintegrant being fermented molasses, a process for preparing the compressed solid composition and also a binding and/or disintegrating composition, which includes at least fermented molasses. The fermented molasses advantageously makes it possible to replace synthetic binders conventionally used in compressed solid compositions, while also being able to act as a disintegrant on contact with a liquid, especially water. Thus, a novel way is proposed for utilizing a product which was hitherto solely used in the field of agriculture and livestock farming.

  • Patent number: 6063147
    Abstract: The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge at a temperature sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure sufficient to form vapor within the cell and to thus rupture the weakened cell walls and thereby release the intracellular water in the form of a hot aqueous vapor and/or released intracellular water. The water-reduced concentrated biosludge can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.
