  • Method for the hydrolysis of lignocellulosic biomass
    Patent number: 11535877
    Abstract: The present invention relates generally to the field of industrial biotechnology and particularly to an improved hydrolysis method for increasing sugar production from a high solids concentration of lignocellulosic biomass, especially one derived from Municipal Solid Waste (MSW) by enzymatic hydrolysis of a lignocellulosic biomass to obtain a slurry, wherein the hydrolysis comprises aliquot additions of enzyme and lignocellulosic biomass; and removal of sugars from the slurry and washing of the residual lignocellulosic biomass.
    Type: Grant
    Filed: April 27, 2018
    Date of Patent: December 27, 2022

  • Waste processing
    Patent number: 11465156
    Abstract: The present invention relates generally to the field of waste processing. The method comprises separating waste into at least two parts, comprising: (i) mainly food waste (fines) and (ii) mainly paper and other recyclable material (overs). The overs are pulped and washed to obtain a cellulose-rich biomass and the fines are optionally processed separately to recover a cellulose-rich biomass and the cellulose-rich biomass from both the fines and the overs may be combined.
    Type: Grant
