TIRANA, Albania (AP) — Albania pledged Tuesday to hold a historic referendum on whether to scrap waste imports, a money-making program strongly opposed by environmentalists who say the poor Balkan country is already buried under its own trash.

A law passed in 2011 allows the import of non-radioactive waste for destruction or recycling in factories. But litter clogs rivers and piles up on the side of roads, and activists say the government can’t be trusted to track the imported garbage.
