A process for forming a pre-form for a moulded pulp fibre product involves providing a porous mould that has one or more pre-form mould portions that each have an outer surface corresponding to a surface of the pre-form. Pulp fibre slurry is discharged from an outlet; each pre-form mould portion is coated with discharged pulp fibre slurry by moving the porous mould relative to the outlet. Thus, a slurry deposit for the pre-form is formed on the outer surfaces of the pre-form mould portions. Fluid from the slurry deposit is extracted through the porous mould to form the pre-form.

Methods and systems are provided for processing constituent materials from brewer's spent grains (BSG) for making packaging and/or products. The spent grains are arranged into a set of balanced constituent materials of approximately 80% to 90% grains, 10% to 20% hops, and less than 1% of spices by weight. This set of constituent materials is then formed into products, such as paper and packaging. The paper can be used to create labels or other carriers for beverages, especially for bottled beverages.
