The invention provides a fiber-reinforced polymer composite comprising fibers derived from mammalian hair and/or feathers, wherein the fibers have been prepared by means of a process comprising the steps of: (a) subjecting mammalian hair and/or feathers to an oxidation treatment in which the hair and/or feathers (is) are contacted with a solution, which comprises a bleaching agent; (b) separating the oxidized hair and/or feathers from the solution; and (c) drying the separated hair and/or feathers. The invention further provides processes to prepare said composite, a process to prepare said fibers, and shaped polymer products comprising said composite.

The invention relates to the use of a particulate material derived from mammalian hair in the preparation of a paper or paperboard product, which particulate material has been prepared by means of a process, which comprises the following steps: (a) subjecting mammalian hair to an oxidation treatment in which the hair is contacted with a solution, which comprises a bleaching agent; (b) separating the oxidised hair from the solution; (c) drying the separated hair; and (d) subjecting the dried hair to a treatment in which the hair is formed into a particulate material having an average particle size in the range of from 0.5 to 4 mm. The invention further relates to a paper or paperboard product, or paper pulp comprising said particulate material.

A process for producing a protein hydrolysate derived from keratin containing material with an oxidative bleaching agent at an acidic pH and mixing the keratin hydrolysate as an additive to the wet-end of a papermaking process. The process achieves a paper with a lower porosity and greater breaking length.
