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.

Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.
