Sustainable Ideas

This week we're talking about clean energy, about rubbish and about pollution, both in the sea and in the air. If you think politicians are rubbish you'll hear of a politician who really is rubbish and proud of it. Should you have your coffee in a china cup or a paper cup or a styrofoam cup? We find the answer in Switzerland. We follow up on tellurium, look at a novel use for hydrogen, gaze through wooden windows and pass on an important message from France.
