The Lulonga Company was a concession company of the Congo Free State.[1] It was, with the Société Anversoise and the Abir Congo Company, one of the main producers of rubber in the Free State.[2] The company's rubber production declined in the early 20th century as a result of over harvesting of the natural rubber vine (Landolphia owariensis gentili) and the entire concession produced just seven tons of rubber in 1905.[3] Like Abir and the Société Anversoise, the Lulonga Company handed back control of the concession to the Congo Free State in 1906.[2]
