[0057] Fiber furnish and degree of fibrillation

[0058] Five samples (A-E) of waste paper based, RCW80 deinked waste paper recovered from Amcor and one sample (F) of hemp cellulose based Hempcell B from Celesa, Spain, were subjected to grinding in a high concentration 22" refiner The fiber (solids) content in the slurry was 16 wt% and the flow rate of the slurry through the refiner was about 200 L / min. The specific energy (the amount of energy transferred from the motor of the refiner to the fibers) input for these samples was :

[0059]

[0060] The specific edge load (the amount of energy applied one meter across the edge of the rod of the refiner plate and transferred to the slurry in one second) was 4-8 Ws / m at the beginning of the refining process, and this load was carried over to the process At the end, gradually reduce to between 1-4Ws / m.

[0061] The fibers are processed until the spread of the average fiber length matches the known "bell curve". Empirically an...

Abstract

The invention relates to a cellulosic composition comprising fibres having a length weighted average fibre length ("LWAFL") of 0.25 to 0.40mm.

Description

technical field [0001] The present invention relates to cellulosic compositions useful as structural building components for objects including, but not limited to, buildings, furniture, automotive parts, coffins, cabinets and boxes, electronic housings, structural building pillars, Beams, panels, sheets, veneers, chairs, musical instruments and toys. Background technique [0002] The large volumes of waste generated in the pulp and paper processing industry are often disposed of in landfills. However, disposal to landfills is becoming a growing problem due to environmental constraints related to land availability and land / soil contamination. As such, there is significant pressure to reduce the amount of waste disposed of to landfill, and one way of reducing this is through recycling. [0003] Recycling paper and textile materials requires breaking down such materials into fibers or fiber-like materials, which can then be reformed into materials to provide paper or paper-li...
