The show, in Birmingham’s NEC runs between April 20 and 22, is free and highlights the latest environmental issues.

The ET theatre will hear from the National Industrial Symbiosis Programme’s (NISP) Ian Humphreys, on the pathway to a low carbon sustainable economy.

The talk will chart NISP’s progress since becoming the world’s first national industrial symbiosis programme in 2005.

Mr Humphrey’s will also set out the ‘compelling argument’ that the business led approach used by NISP has the potential to fulfill a key role in the transition towards a low carbon sustainable economy.

Mr Humphrey’s will be speaking at the ET theatre on Wednesday (April 21) from 2.30pm to 3pm.
