Khalid Mollah died while working among the thousands who dismantle old ships in Chittagong. Now, in a test case that could transform the industry, his widow is suing the firm that sold the vessel for scrap

Khalid Mollah was uneducated, illiterate and out of work when, in early 2009, he left his pregnant wife Hamida Begum to take the 200-mile bus ride to Chittagong from the small village of Gopai, in northern Bangladesh. The young man’s destination was Sitakunda, the notorious, 20km stretch of wide beach and tidal mudflats just north of Bangladesh’s fast-growing second city.

Here, nearly 25,000 people work in dozens of ship-breaking yards, steel-rolling mills and factories to recover and sell on every bit of plate metal, deck, mast, funnel, hatch, gangplank, wire, nut, cable, bolt, wood and rivet that makes up the world’s giant ships.
