Shipping containers are a staple of global trade, helping in the transport of all sorts of goods by sea across the world. But their relatively cheap cost and sturdy structure lends them to many other purposes. In this episode we look at a start-up business in the UK that uses shipping containers to store carbon captured from the air in the production of building materials. And we visit a school for poorer children created out of shipping containers that sits in the middle of a busy intersection in Mumbai, India.
