Abstract: A fish feed includes carvacrol and/or salvia extract (provided that where the fish feed comprises carvacrol and not salvia extract the lipid content of the fish feed is at least 15 wt %). The salvia extract may be selected from extract of Salvia officinalis and extract of Salvia lavandulifolia. The carvacrol may be synthetic or may be extracted from Origanum vulgare.

Abstract: A catalytically degradable plastic is described, with content of cellulose esters and also optionally of additives. A particular characterizing feature of this catalytically degradable plastic is that it contains a dispersed, catalytically active transition-metal-modified titanium dioxide.

Abstract: The invention relates to a biodegradable plastic having increased biodegradation speed. Said plastic comprises a) finely distributed particle of a biodegradable, water-soluble, organic component, and b) finely distributed particles of a water-soluble, inorganic component promoting the growth of microorganisms and comprising N, P, and/or S. Said plastic is particularly based on cellulose esters such as cellulose acetate. Preferable components A are water-soluble saccharides and/or water-soluble organic acids. Said particularly advantageous biodegradable plastic is particularly available in the form of fibers, films, injection molded items, granulate beads, and containers. Controlled-release biocides and/or fertilizers can also be included in the molded part, wherein the molded part is degraded faster in the environment as said ingredients are released. The accelerated biodegradation is based on a synergistic interaction of the components indicated.

Abstract: A photodegradable plastic is described, comprising cellulose esters and also, if appropriate, additives. A particular characterizing feature of this photodegradable plastic is that it comprises a dispersed photocatalytic carbon-modified titanium dioxide. Comparative experiments show that this photodegradable plastic exhibits a surprisingly high increase in photocatalytic degradability when compared with products in which a conventional or other modified titanium dioxide is used. This improvement is apparent in particular in use of the photodegradable plastic according to the invention when it is further processed to give moldings. The photodegradable plastic can, for example, first be further processed to give a filter tow. This can be used to produce filter rods, and these can then be used to produce filter plugs for filter-tip cigarettes.

Abstract: A rearing fodder of extruded fodder type, comprising proteins, fats and carbohydrates, for freshwater fish, wherein the fish is larger than 2 grams, and wherein the freshwater has a content of CO2 being above 5 milligrams/litre, wherein the fodder has an increased content of at least one of the minerals: phosphate (P), potassium (K), calcium (Ca), sodium (Na) and magnesium (Mg) beyond what exists naturally in the used protein raw materials, fat raw materials and carbohydrate raw materials, wherein the collective amount of minerals in the extruded fodder is at least 10%, on a dry substance basis, of the total weight of the fodder, and wherein one or more of the minerals phosphate (P), potassium (K), calcium (Ca), sodium (Na) and magnesium (Mg) is/are added beyond what exist in the used protein raw materials, fat raw materials and carbohydrate raw materials.

Abstract: The invention is directed to a cellulose acetate filaments.

Abstract: There are described filaments on the basis of a cellulose acetate soluble in acetone, the degree of polymerization (DP) of the cellulose acetate being between about 110 and 210 and the degree of substitution (DS) preferably between about 2.2 and 2.7. Optically isotropic spinning solutions can be obtained, the cellulose acetate concentration of which is about 35 to 47 mass-%. When such an optically isotropic spinning solution is spun, in particular by dry spinning, filaments are obtained in a profitable manner because the costs connected with the recovery of the acetone can be appreciably lowered, without impairing the desirable properties of the filaments, which are suitable in particular for the production of cigarette filter tow.
