After exploring our wasteful past and the reality of today’s trash challenge, Australian journalist Alexandra Spring asks if we are on the tipping point of a rubbish free future.

Alexandra joins blogger Kathryn Kellogg to find out more about San Francisco’s growing zero waste ambitions. Encased in one single mason jar, Kathryn describes the tiny amount of waste she created over two years and how living without a trace has changed her life.

Then, Alexandra meets the inventor Veena Sahajwalla, who shares her belief that we should consider our rubbish to be a resource for the future. As Alex discovers, this attitude and Veena’s engineering skills have stopped millions of tyres from ending up in rubbish dumps, and could lead to cities around the world being built from recycled materials.
