The St Austell and Clay Country Eco-town is a plan to build a new town on a cluster of sites owned by mining company Imerys near St Austell, in Cornwall, England. The plan was given outline government approval in July 2009. The plan would need to gain full planning permission before construction commenced.
A number of organisations are involved in the development. A joint venture company called ECO-BOS has been set up by Imerys, and Orascom, with assistance from the Eden Project. This company will prepare the planning application and build the development if granted. Cornwall Council will lead on some part of the project.
