We examine technologies that might lead to greener steel production, and ask who will pay. Professor Veena Sahajwalla of the University of New South Wales in Australia discusses her research into using waste such as car tyres to produce the metal. We hear about Swedish steelmaker SSAB's hydrogen manufacturing process, which is being piloted to produce steel with water as the only by-product. And Alan Knight of steelmaker ArcelorMittal tells us about his company's goal to mitigate carbon emissions through capture and storage of pollutants. Also in the programme, following a policy review the UK is to shift its focus to Indo-Pacific countries such as India, South Korea and Japan. The aim is partly to foster a democratic counterweight to China, and we explore the economic implications with Professor Laura Cleary, director of the consultancy Oakwood International Security. Plus, it's exactly a year since the pandemic forced the lights to go down on London's West End theatres. Nica Burns is co-founder of the Nimax Theatres group, which owns six venues in London including the Vaudeville and Garrick theatres, and explains what life has been like for the theatre industry over the past 12 months.
