There is provided a fiberboard, such as a MDF fiberboard or a HDF fiberboard, comprising wood fibers, a binder, and a sludge such as a pulp and a paper sludge. The sludge can be, for example, chosen from a primary pulp and paper sludge, a secondary pulp and paper sludge, a de-inking sludge, and mixtures thereof.

A method for manufacturing an edible, multi-ring, can holder comprises the steps of dehydrating beer by-product to produce a dried pulp, grinding the dried pulp into a powder, forming a pulp slurry by adding the powder into a mixture comprising plant fibers, an environment-friendly, oil-repellent chemical, an environment-friendly, water-repellent chemical, and water, a water-to-other ingredient ratio being approximately 1000 liters of water to approximately 60 kg of the powder, the plant fibers, the oil-repellent chemical, and the water-repellent chemical, injecting the pulp slurry into a mold having an interior cavity in the shape of at least one six-pack ring, and applying pressure and heat to the mold containing the pulp slurry to produce at least one edible six-pack ring.

A paper formed of at least two layers of different compositions couched together. A first layer forms a carrier layer. A second layer forms a cover layer. The paper contains waste paper fibers and additional fibers in the form of fibers other than waste paper fibers. The additional fibers contain a proportion of fibers from the cup plant (Silphium perfoliatum). fibers from fruits and/or the barks of trees of the baobab genus (Adansonia), fibers from plants of the genus Cannabis, and/or fibers originating from residues of biogas facilities.

The carrier layer has a proportion of additional fibers equal to 0 to 75 wt %. The cover layer has a minimum proportion of additional fibers equal to about 8 wt % and a maximum proportion equal to about 80 wt %. The additional fibers in the cover layer is higher than the additional fibers content in the carrier layer.

The present invention relates to a structurally enhanced agricultural product containing cellulose filaments (CF), and a method for producing the structurally enhanced agricultural material into the sheets. Applying CF improves significantly the wet-web strength of the agricultural material sheets. The method comprises preparation of a pulp slurry of agricultural materials followed by mixing with a water suspension of CF or CF-containing cellulose fibers. The pulp blend is then used to produce an agricultural material sheet by papermaking process.

Composite pulp compositions for making paper are disclosed that include agricultural residue fibers, softwood fibers, and water. The composite pulp compositions are made by blending an agricultural residue with softwood chips and simultaneously and mechanically pulping the mixture of agricultural residue and softwood in one or more TMP and/or RMP operations. The agricultural residue is present in an amount in a range from about 1% to about 30% of the oven dry weight of the composite pulp composition. Co-pulping the agricultural residue with the softwood improves the tear strength properties of the composite pulp composition. Blended pulp compositions are also disclosed that include a chemical pulp or chemi-mechanical pulp blended with the composite pulp compositions having agricultural residue fibers and softwood fibers. Paper products made from the composite pulp compositions and blended pulp compositions are also disclosed herein.
