Sophie is an unusual mix of campaigner, practising designer and Chartered Waste Manager. She’s been working in the fields of sustainable design, behaviour change and material process for nearly 20 years. I invited Sophie on to the show to talk about waste and circular design. In our conversation we get into:

• The engineering of linear and circular products, material selection, recycling houses and oil rigs.
• The creative strategies for circular designers, and in particular the idea that waste is a design flaw.
• And the practical philosophy of someone who has spent so long think about waste.

An engineering detour is something engineers do when they go out of their way, usually on holiday, to go and check out a piece of engineering infrastructure. In this episode I take an engineering detour to the mighty Forth Bridge. Along the way we get into

• the engineering of the structure,
• how taking detours can build our creative skills,
• and on a philosophical note I weigh up facts and figures versus experiential knowledge.

Join me for the ride!
