Across the world, everyday products — from kitchen appliances to electronics — are often thrown away rather than repaired. The latest UN estimates suggest people generate around 2 billion tonnes of household and everyday waste each year. This week we travel to Argentina to meet people finding new ways to keep old things in use. We visit Club de Reparadores, where people are learning how to fix everything from toasters to microwaves, meet the women behind Lindor who transform old blankets into coats, and join the group Cybercirujas as they find new uses for discarded computers.

At least once in a lifetime, everyone has a great business idea. They often come when life events force us to experience things from a different angle. This year, the city of Liverpool in north England set about finding these “hidden entrepreneurs” with the help of an organisation called Public Life. The entrepreneurs come from all walks of life and have been offered a year’s wage to develop their idea, alongside expert help and mentoring. From the hairdresser who is building a salon-on-wheels for her best friend to the travel agent who is making a "Trip Advisor for the senses", Myra Anubi meets the people whose inspiration has come from their own life experiences.

In Bergen, Norway, a two-day ageing festival is testing out new ways to build an age-friendly society—through culture, conversation and shared experiences. Myra Anubi joins in, meeting the people finding creative answers to loneliness, mental health, care and belonging, and hearing hopes for a future where generations mix rather than separate. From masterclasses to inspiring collective events, the festival’s aim is to make ageing something we can all become more comfortable with and even celebrate.

People trafficking is a crime that often takes place in plain sight - victims are often exploited and controlled in everyday situations. It’s also a crime that touches all of us - the food we eat, the phones we use, the clothes we wear, may all have been produced using slave labour. We’ll hear about ways to break the cycle of trafficking. In the US we take a ride with Truckers Against Trafficking, an NGO that trains truck drivers to look out for vulnerable people who may be being trafficked for forced labour, including sex work. And in Nepal we meet SASANE, the organisation training survivors of trafficking to become paralegals - to provide them with a new career and also help encourage others to pursue justice through these fellow legally-trained survivors.
