Prince Charles "can't bear" throwing anything away.
The 71-year-old royal admitted he'd rather find "another use" for waste products, whatever they are, and branded single-use society a "tragedy" that is leading to natural resources being "over-exploited".
He said: "I'm one of those people who hate throwing anything away… I can't bear any waste, including food waste; I'd much rather find another use.
"Which is why I've been going on for so long about the need for a circular economy, rather than a linear one where you just make, take and throw away – which is a tragedy, because inevitably we over-exploit natural resources that are rapidly depleting."
