A method and system to produce treated Cellulose Filaments (CF) and CF products are provided. Feedstock comprising CF in a water solution are mixed with a debonder to produce a mixed stream. The mixed stream is filtered yielding separate filtered and filtrate streams. The filtrate stream comprises at least a portion of the debonder. The filtered stream is dried to produce treated CF. The debonder is one of an alcohol, glycol ether, ester-containing quaternary ammonium salt, amido amine quaternary ammonium salt, disubstituted amide or a mixture thereof. The filtrate stream may be recycled. The mixed stream may be washed before filtering to remove debonder. A thermoplastic polymer-treated Cellulose filament composite material is formable by associating the treated CF with a thermopolymer such as polyolefin, polyurethane (PU), polypropylene (PP), polyester (PE), polylactic acid (PLA), polyhydroxyalkanoates (PHA), polyamide (PA), and ethylene vinyl acetate (EVA) or a mixture.

A method for continuous steam explosion discharge of a pressurised reactor for thermal treatment of lignocellulose biomasses. The steam explosion discharge is complete decoupled from the thermal treatment step and the loss of steam from the process is fully controlled without jeopardizing the mechanical disintegration of the lignocellulose material from the process.

A processing liquid is generated by mixing a chemical and water in a processing liquid generation region disposed below an inner tank. By further supplying water to raise a water level, the processing liquid is supplied from below the inner tank. This prevents a used paper diaper from coming into contact with water containing no chemical.
