Coconut husk and coconut shells are primarily considered agricultural waste. Therefore, coconut shells are often burned, which is terrible for the environment and contributes significantly to CO2 and methane emissions. Thus, the present invention provides an eco-friendly use for coconut waste by turning coconut fibers into thermo-acoustic insulation. The present invention also describes methods of producing said insulating compositions.

A device and a method for the production of a fiber mat is suitable in particular for use in the production of packaging board or fibrous construction elements, from a fibrous source material. The method includes providing the fibrous source material, low-water processing of the fibrous source material in an airflow into raw material including individual fibers and/or fiber bundles, forming of the individual fibers and/or fiber bundles in the airflow by a dry forming method into a fiber mat in such a way that a spatial or three-dimensional structure is formed by the fiber mat and consolidation of the formed fiber mat. The specific volume of the fiber mat is greater than 1.6 cm.sup.3/g, in particular greater than 2 cm.sup.3/g, preferably greater than 3 cm.sup.3/g, and the fiber mat thickness ≥1 mm, in particular ≥1.5 mm, preferably ≥2 mm.

The present invention relates to a method of manufacturing a cellulose product having a flat or non-flat product shape by a pressure moulding apparatus comprising a forming mould. The forming mould has a forming surface defining said product shape, The method comprises the steps of:

arranging a cellulose blank containing less than 45 weight percent water in said forming mould; heating said cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing said cellulose blank by means of said forming mould with a forming pressure acting on the cellulose blank across said forming surface, said forming pressure being in the range of 1 MPa to 100 MPa.

An aqueous binder composition is provided that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.
