Abstract: There is provided a method for preparing composite materials from renewable raw materials wherein natural raw materials, especially in fiber form, comprising starch as binder are molded by adding water in accordance with a predetermined temperature and time profile to form boards and molded articles. The advantages of this method reside in said materials being fully biodegradable and free from harmful substances.

Abstract: The present invention relates to a compostable adhesive, to a method of producing the same, and to the use of the adhesive for the adhesive bonding of materials.

Abstract: There is provided a biodegradable filter tow or filter material from renewable raw materials for the use as a tobacco smoke filter element of cigarettes, cigars or pipes as well as a method for preparing it, wherein fibers, films or foams prepared in an extrusion method from biopolymers based on thermoplastic starch or its polymer compositions are processed to the filter tow or filter material according to the present invention.The advantages of this invention reside in the use of mainly renewable raw materials, a fast and complete biodegradability of the natural biopolymer filter material, a pollutant-reducing flavor-increasing filtering effect and an economically favorable preparation method.

Abstract: The invention relates to a molded part made of completely biodegradable starch foamed material to be used for protecting transported articles and to a method for its preparation, wherein the starch foamed material is expanded to form starch foam profiled sections which are self-adhesive when moisture is applied and can be processed individually or so as to form single or multi-layer foam panels. The advantages reside in improved operating properties and minimized expenditure on packaging.

Abstract: A process for the production of a glass or other mineral fibre composition in which glass or other mineral fibre is melted, the molten glass or mineral is forced through a plurality of openings to produce fibres, the hot fibres are sprayed with a water disperion of a binder and the fibres are dried at an elevated temperature, the binder comprising a gelatinized starch sulphamate product and a hydrophobic agent such as a silicone. The gelatinized starch sulphamate may be preformed by reacting a starch with a sulphamate salt or may be formed in situ by spraying onto the hot fibres a water dispersion of pregelatinized starch and a sulphamate salt. In this latter case part of the pregelatinized starch may be replaced by native starch.
