A wildlife trust has raised concerns about proposed plans to dispose of dredged sediment from Brighton Marina near Newhaven, suggesting that the area might not be the best option. The issue has arisen after the Sussex Wildlife Trust successfully challenged a previous licence in 2025 for sediment disposal at Rottingdean, a nearby location. Brighton Marina, which requires regular dredging to keep its waters navigable, is now seeking a long-term solution for disposing of the material it removes. However, the trust has expressed reservations about using Newhaven, which lies near a protected marine area. Brighton Marina, operated by Premier Marinas, argues that dredging is essential to maintain safe access for boats and to support the local economy. The marina is described as a key economic driver in the region, supporting around 150 businesses, providing jobs for approximately 1,200 people, and attracting over eight million visitors annually. Premier Marinas has stated that the dredged sediment is regularly tested to ensure it is not harmful to the environment. The Sussex Wildlife Trust has pointed out that Newhaven is near the Beachy Head West Marine Conservation Zone (MCZ), an area designated for its ecological importance. While campaigners have described the dredged silt as "black, thick, slimy, petrochemically smelling sludge," Premier Marinas insists that the material is routinely sampled to ensure it meets environmental standards. The trust clarified in a recent social media post that it had not endorsed Newhaven as a disposal site, despite its identification as a potential alternative. It also noted that Newhaven is already used for dredge disposal by Newhaven Port and that there is currently no data on the environmental impact of increasing that activity. Until further evidence is available, the trust has stated it will not support or oppose the use of Newhaven for additional disposal. Brighton Marina is expected to submit a marine licence application to the Marine Management Organisation in November. If approved, dredging operations could resume in the spring, ensuring continued access for vessels while the environmental and economic implications of the disposal site choice remain under review.
