    摘要： Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.

    摘要： The present invention relates to a system and a method for recycling white water during production of fibre molded products. The method comprises:
    a) forming a wet fibre molded product in a forming unit (1) using a furnish comprising white water;
    b) dewatering the wet fibre product and producing a dewatered fibre molded product and a white water stream (4*);
    c) drying the dewatered fibre molded product and producing a dried fibre molded product and a steam stream (5*);
    d) condensing the steam stream (5*) by mixing the steam stream (5*) and the white water stream (4*) and producing a mixed white water stream (6*);
    e) reducing the temperature of the mixed white water stream (6*) to 50 °C or less;
    f) storing the mixed white water stream (7*) in a white water tank (8); and
    g) providing the white water (8*) from the white water tank (8) to the forming unit (1) for preparation of the furnish.

    摘要： The present invention relates to a method and a device for introducing an expandable tool (20) into a container (30). The container (30) has a container body (31) and a container neck (32). The expandable tool (20) has a body (21) and a neck (22). The method comprises the steps of:
    - providing the expandable tool (20) in an everted form
    - holding the neck (22),
    - providing the container (30) such that the container neck (32) and the neck (22) are arranged opposite one another.
    To introduce the expandable tool (20) into the container (30), the expandable tool (20) is blown into the container (30) through the neck (22).

    摘要： Method for producing a sound absorbing panel (F) comprising the step of providing a predetermined amount of cellulose fibres. Cellulose fibres have an average length comprised between 0.5 mm and 5 mm, preferably comprised between 1.3 mm and 2.5 mm. The method further comprises a step of soaking the cellulose fibres in a water basin (100) to form a pulp (P) and a step of depositing the pulp (P) on a moulding die (200). The method further comprises a step of pressing said the pulp (P) in order to cause at least a partial removal of the water contained making a fibre mat (T). The method also comprises a step of drying the fibre mat (T) so as to cause evaporation of the water remained in the fibre mat (T) making the sound absorbing panel (F).
