Abstract: Recovering bromine from solid waste containing bromine compounds, and applications thereof, such as for recovering bromine in a form suitable for reuse, or for manufacturing bromine salt (for example, calcium bromide). Bromine recovery method and system include: providing and mixing (i) solid waste containing bromine compounds and (ii) solid calcium hydroxide; heating the mixture in a chemical reducing (non-oxidizing) environment, thereby forming heated product consisting essentially of only solid calcium bromide (salt); and processing the heated product, to form bromine. Calcium bromide manufacturing method and system include: providing and mixing (i) solid waste containing bromine compounds and (ii) solid calcium hydroxide; heating the mixture in a chemical reducing (non-oxidizing) environment, thereby forming solid calcium bromide (salt). Applicable to processes of, or involving, manufacturing bromine-based flame (fire) retardant materials.

Abstract: Processing solid waste containing fluorine compounds, and applications thereof. Solid waste processing method includes: providing and mixing (i) solid waste containing fluorine compounds and (ii) solid calcium hydroxide, for forming a mixture thereof; heating the mixture in chemical reducing (non-oxidizing) environment, thereby forming a heated product including solid calcium fluoride; and handling or/and processing the heated product, to form non-hazardous safely disposable material. Solid waste processing system includes: solid waste input unit; solid calcium hydroxide supply unit; mixing unit; heating unit; and product handling/product processing unit. Applicable to large scale commercial processes of, or involving, manufacturing materials and products containing fluorine compounds during which are generated large amounts of solid waste containing fluorine compounds, whereby such solid waste needs to be handled or/and processed, and disposed of.
