A method of separating constituent layers from a paper-plastic laminate material includes disposing a sheet of a paper-plastic laminate material on a first surface. The paper-plastic laminate material includes a paper layer on a first side and a plastic layer on a second side. The method also includes moving an abrasive second surface over the paper layer on the first side to contact the paper layer and separate portions of the paper layer from the plastic layer. The method further includes collecting the separated portions of the paper layer and providing the separated portions of the paper layer as input to a paper recycling process, and collecting the plastic layer and providing the plastic layer as input to a plastic recycling process. The method may help increase recycling rates of paper and plastic, reduce raw material harvesting, reduce pollution and habitat destruction, and improve the quality of recycled material.

A method for recycling polyester fabrics with use of an ionic liquid catalyst is provided, which includes: providing a recycled polyester fabric; and using a chemical de-polymerization liquid to chemically de-polymerize the recycled polyester fabric and form a de-polymerization product that includes bis-2-hydroxylethyl terephthalate (BHET). The chemical de-polymerization liquid is used to chemically de-polymerize the recycled polyester fabric in an environment where a de-polymerization catalyst exists, and the de-polymerization catalyst is the ionic liquid catalyst in a solid state.

Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.

The disclosure relates to the field of solid biofuels obtained by steam cracking. More particularly, the disclosure relates to a process for the treatment of lignocellulosic biomass by steam cracking in which the obtained powder is treated in order to separate the particles into two categories according to a threshold value, and each category is treated differently.

The present invention relates to insect-based biowaste processing apparatus. More specifically, the present invention relates to a substantially continuous insect-based biowaste processor that comprises a tubular drum having a longitudinal axis and an interior; a drive for rotatably driving said drum about said axis; a shaftless screw conveyor fixedly connected to an inner surface of said drum; a plurality of circumferentially spaced cantilevered blades that are connected to said inner drum surface and that each longitudinally extend throughout said drum; and means for introducing a conglomerate portion that includes biowaste and insect larvae into said drum interior, wherein said screw conveyor is subdivided into a plurality of longitudinally spaced rearing chambers for the introduced insect larvae, each of said rearing chambers being defined by two longitudinally adjacent flights of said screw conveyor and by said circumferentially spaced cantilevered blades and within which insect larvae of a substantially uniform developmental stage are retained, wherein two or more of said circumferentially spaced cantilevered blades are configured to firmly hold and unify said conglomerate portion at any given instance throughout its residing time within said drum interior while being distally conveyed, and wherein the insect larvae are progressively more developed within a more distally located rearing chamber.

A method for producing a biofuel by continuous or discontinuous steam cracking of lignocellulosic biomass includes: —recording a digital model of the optimal steam cracking parameters as a function of the nature and the content of the contaminants; —introducing a biomass containing at least part of the contaminated biomass into the steam cracking reactor; —measuring at least once during the treatment the nature and content of the contaminants; and —controlling the adjustment of the steam cracking parameters as a function of the nature and the content of the measured contaminants and of the digital model.

The present invention provides a system for thermal remediation and/or the processing of a feed materials like contaminated materials, waste polymeric materials, waste paper products, waste wood and biomass. The system comprises at least one thermal screw conveyor provided in a housing under pressure, a first plug screw conveyor in a housing in communication with an inlet of thermal screw conveyor housing and a second plug screw conveyor in a housing in communication with an outlet of thermal screw conveyor housing. The thermal housing is configured to heat the feed material to form one or more vaporized products and a solid residue, wherein one or more vaporized products are removed through the one or more vapor ports provided in the pressure housing, and the solid residue is discharged from an outlet of the second seal-housing.

A recycling and fabrication appliance is provided. The recycling and fabrication appliance is generally configured to convert solid waste, solid materials and/or solid objects into a usable or reusable product. The recycling and fabrication appliance generally comprises a single unit with one or more inputs and one or more outputs. The unit may be a cuboid, or may be any appropriate shape, and may specifically be configured to recycle or repurpose solid waste, solid materials or solid objects into a reusable form at or near the point of consumption or disposal, such as a household or office. The components of the recycling and fabrication appliance may be housed within the unit and may enable the recycling and fabrication appliance to receive various solid waste pieces as an input and to produce a single usable output, referred to herein as a output object.

A waste treatment system comprises: a first hydrothermal treatment device for performing hydrothermal treatment of waste; a first solid-liquid separation device for separating a first reactant of the first hydrothermal treatment device into a solid and a liquid or slurry; a second hydrothermal treatment device for performing hydrothermal treatment of the solid of the first reactant; a second solid-liquid separation device for separating a second reactant of the second hydrothermal treatment device into a solid and a liquid or slurry; and a fermentation device for fermenting the liquid or the slurry of the first reactant and the liquid or the slurry of the second reactant.
