Leave No Trace – An Ethical Environmental Principle

How do we design products which leave no traces of waste (or not more than can be sustainable)?

And how do we create commercial advantages from it?

It’s an ideal, but without goals there is no progress.

Interestingly the Swiss government already locates leaks in it’s waste water treatment plants, by tracing back the non-biodegradable artificial sweeteners (used in food and drink) from contaminated Swiss lakes through springs and rivers.
