  • 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
    Filed: December 8, 2016
    Date of Patent: October 11, 2022
    Assignee: FIBERIGHT LIMITED
    Inventors: Charles Banks, Nicholas Mark Thompson, Dhivya Jyoti Puri, Peter Speller, Craig Stuart-Paul

  • WET PULPING SYSTEM AND METHOD FOR PRODUCING CELLULOSIC INSULATION WITH LOW ASH CONTENT
    Publication number: 20110011544
    Abstract: Apparatus and method for recovering organic cellulosic fibers from landfill materials (such as post consumer, municipal and industrial waste materials). The apparatus and method selectively introduces waste materials containing organic cellulosic fibers into a size reduction machine. The pre-cleaned waste materials are conveyed to a tank, drum, or tunnel type fiber recovery apparatus. The waste materials are subjected to mechanical and fluid fiberization for a selected period of time to produce useful products, such as cellulosic insulation with a total ash content equal to or less than 10%, as well animal and fowl bedding products that is substantially devoid of moisture content, among other products.
