Belgarena has its own sheltered dock for crafts of up to 1200 metric tonnes or barges of up to 800 metric tonnes that enables it to give priority to river transport. As a result, more than one-third of its shipments of materials is kept off the roads. This considerably reduces the pollution and problems linked to road transport, that is fossil fuel consumption, greenhouse gas emissions (CO2, NOx), fine particles, vibrations and noise that annoy residents, clogged roads, and increased risks of traffic accidents.
