Bird Island (Namibia) for its high nitrogen content relative to other guano collection facilities in the region. It is cleaned in Swakopmund to remove feathers and other debris, ground to a powder, and exported to Belgium for US$285 per ton. The platform yields approximately 650 tons of guano annually.
