Franziska Trautmann and Max Steitz decided to start a recycling project in New Orleans after realising the city sent all its glass to landfill. Now their social enterprise Glass Half Full diverts hundreds of tonnes from landfill and is using the material to help shore up Louisiana’s eroding coastline. Franziska tells us how they are expanding the project and we hear from one of their first business customers. We also find out why gaps in the recycling system mean the city’s waste glass can’t easily be turned back into new bottles.
