There are, owing perhaps to the proximity of Lima, few industrial establishments in the city; among them are a large sugar refinery, some flour-mills, a brewery, a factory for making effervescent drinks, and a number of foundries and repair shops.
A refinery was attached to the London Mint from 1816 to 1851, but was then let on lease and left to private enterprise.
A modern sugar-mill and refinery at Sincerin, 28 m.
There is one large refinery at Villa del Mar, however, which imports raw cane sugar from Peru for refining.
Near Doboj, on the Bosna, there is a state sugar-refinery, for which beetroot is largely grown in the vicinity.
