Mr. Liam McCarton:

To move to the context, what we are talking about is not necessarily innovation in technology. The technology exists and while there are certain issues with it which need to be addressed, it is really an innovation in thinking that is needed. It might be asked where this is used. Singapore is one example of a location which has developed what is not called a zero waste approach but is, in effect, a value chain. Again, this was born out of necessity, given Singapore was reliant on importing water from Malaysia.
