Abstract: Fire-retardant powder comprising at least 30% by weight of Lewis acid, at least 5% by weight of alkaline bicarbonate, and at least 3% by weight of silica, and method of manufacturing such fire-retardant powder. A building material preferably comprising natural fibers and comprising at least 5% by weight and at most 30% of such powder.

Abstract: Fire-retardant powder comprising at least 30% by weight of mono ammonium dihydrogen phosphate and/or di-ammonium monohydrogen phosphate, at least 5% by weight of alkaline bicarbonate, at least 3% by weight of silica, and at least 5% by weight of a compound selected from the group consisting of: sodium chloride, potassium chloride, potassium bromide, potassium sulfate, magnesium carbonate hydroxide pentahydrate, magnesium chloride hexahydrate, iron(II) sulfate heptahydrate, zinc (II) chloride, and combinations thereof. The invention also relates to building materials preferably comprising natural fibers and comprising at least 5% by weight, and at most 30% of a powder according to the invention.

Abstract: Process for controlling the development of parasites in an animal environment equipped with an air introduction device, according to which a parasiticidal powder composition is introduced into the air introduction device, preferably according to which the air introduction device comprises one or more point(s) of introduction of air into the animal environment located close to the animal droppings. The invention also relates to the use of the process, to the use of a parasiticidal composition in an air introduction device for controlling the development of parasites in an animal environment, to a device for controlling the development of parasites in the animal environment, and to a livestock building equipped with such a device.
