A method of and an arrangement for recycling mineral wool waste to mineral wool production includes at least one melting furnace for melting virgin mineral wool raw material, the melting furnace including an inlet for virgin mineral wool raw material and an outlet for molten mineral wool material, a production line connected to the outlet for molten mineral wool material for producing a mineral wool product from the molten mineral wool material. The production line includes a curing oven, a fluidized bed reactor including an exhaust gas duct, an inlet for predetermined primary fuel, an inlet for predetermined bed material, and an outlet for an ash material, the ash material including bottom ash discharged via a bottom outlet from the fluidized bed reactor or fly ash separated by a particle separator from exhaust gas in the exhaust gas duct or a mixture of the bottom ash and the fly ash.

A bulk material transport system includes one or more bulk material transport bins, weighing platforms, and vehicles arranged in various combinations as bulk material transporters, assemblies, and units. The system is useful for coupling with a bulk material container, forming a reduced pressure region at an inlet of the transport bin, and dispensing bulk material into the transport bin through the reduced pressure region.

The present invention relates to a briquette used for the production of rock wool and method for the production of said briquette, wherein the briquette contains a raw material comprising rock wool waste having a fiber morphology; contains a non-fibrous inorganic binder, such as sodium silicate, to bind the raw material; and an activating agent accelerating the curing process of the briquetted raw material.

Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.
