Stable shores and sustainable sand production
Andrew Fletcher has produced a short video showing the loss of the £1.5m Ridgemont House due to erosion, and how tree planting can at least mitigate the effects of this.
He points out that were such measures used in the UK, making the concrete from sand from the surplus waste from quarries (like the Japanese did when they found that dredging was decimating their fish breeding grounds), marine aggregate dredging could be terminated.
In fact, sand manufactured by this system from UK quarries has been extensively tested in the UK over the last three years, showing that natural sands can be completely replaced using waste. A paper has been written by Cardiff University’s engineering department on the subject. major aggregate companies in the UK have all run their own tests and are satisfied with the technology.
