A method for treating process material using a plurality of autoclaves, wherein each of the plurality of autoclaves cycles through the following: introducing steam from one or more of the plurality of autoclaves into an interior of a vessel; increasing the temperature within the vessel by adding heat to the interior of the vessel using an indirect heat source; reducing the temperature and pressure within the vessel by flashing a portion of the steam within the interior of the vessel to another one of the plurality autoclaves; increasing the temperature within the vessel by continuing to add heat to the interior of the vessel using the indirect heat source; and reducing a moisture content of the process material in the interior of vessel to a predetermined value by venting a remaining portion of the steam to another one of the plurality of autoclaves.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

A method of dissolving lignocellulosic biomass waste includes obtaining raw lignocellulosic biomass waste, reducing a size of the biomass waste to provide a biomass particle size of less than about 200 μm; using dimethyl sulfoxide (DMSO), sodium hydroxide (NaOH) and trifluoroacetic acid (TFA) solvents to dissolve the biomass particles and achieve a dissolved lignocellulose solution. The present method dissolves at least about 94% of the lignocellulose fraction in the waste biomass. In an embodiment, the biomass particle size can be about 180 μm.

The present invention provides a liquid-absorbing raw material processing system and its operation method. The liquid-absorbing raw material processing system is composed of a cutting module, a bulk pulping module, a salt slurry processing module, and a liquid-absorbing raw material manufacturing module, which are connected in series. The operating method of the liquid-absorbing raw material processing system is to process absorptive articles such as diapers or sanitary napkins, etc., which are retained and made into fluff liquid-absorbing raw materials through the purification and separation steps performed by the modules of the liquid-absorbing raw material processing system.
