I’ve been reading ‘Eden’ by Tim Smit so to get a glimpse of what eden is about and its history etc. There are some interesting points about the geology of the Bodelva site where Eden is situated. The Eden project is sited within a disused china clay mine near St Blazey which produced fine white clay for the porcelain industry and then later for the paper industry. The refinement process for the clay involved filtering out all the sand and hardcore that was mined with the raw clay. This produced 17 tonnes of sand per 1 tonne of white clay which then presented a problem for the mining companies. This was literally piled up around cornwall on land that was aquired by the company, these formed pyramid shaped hills that form some of cornwall’s topography that we see today.
