  • Process and device for continuous liquefaction of organic solids
    Patent number: 8945892
    Abstract: A method for the continuous liquefying of organic solids in a fermenter, wherein an outwardly directed flow of solids is produced in a dammed-up liquid, the solids are added in the lower region of the fermenter and the solid fermentation residues are essentially collected and removed below the level of the dammed-up liquid.

  • Magnetic glass particles for use in biogas plants, fermentation and separation processes
    Patent number: 8637300
    Abstract: A method for treating an organic and/or inorganic substrate utilizing a granular material made of a solid foam as support for an active component, for example a biocatalyst such as a microorganism or an enzyme. The solid foam has a continuous phase in which magnetizable particles are embedded, such that the support with the biologically active component immobilized thereon can be separated from a mixture with a magnetic separation device.
