From Tide PODS to electronic recycling, Tomorrow’s World Today has covered many innovations that are making our world more sustainable. In honor of our sixth season premiering on September 9, the Tomorrow’s World Today team picked some of our favorite episodes that feature sustainability efforts shaping the world.

1. Power of the PODS – Season 3, Episode 2

Did you know that about 90 percent of the energy used by washing machines during laundry goes towards heating the water? As a result, switching to cold water saves most of the energy that is used. To find out more about how detergent is being created to improve sustainability and conserve energy and water, our host George Davison visited Tide’s headquarters in Cincinnati.

2. Sustainable Hotels – Season 3, Episode 4

In the travel and hospitality industry, the need for more eco-friendly accommodations and activity options is growing across the globe. In this episode of Tomorrow’s World Today, we visit Dubai to discover how IHG (Intercontinental Hotels Group) is working to become more sustainable and innovative. We also investigate how many locations are also working to incorporate more ecotourism options into their offerings.

3. Plastic to Fabric – Season 2, Episode 7

About 11 million tonnes of plastic reaches the ocean every single year–that’s equivalent to dumping one garbage truck of plastic into the ocean every minute of every day for an entire year! In this episode, we visit Costa Rica to find out how Sperry is working to reduce this number by collecting plastic bottles and turning them into high-quality threads to be turned into shoes. 

4. Sustainable Distilling – Season 3, Episode 5

On this episode of Tomorrow’s World Today, we visit Bulleit’s distillery in Kentucky to see (and taste!) how tradition is blending with science and innovation on the Bourbon Trail. We also discover the sustainability initiatives Diageo is taking to use 100 percent renewable energy for its own operations by 2030. 

5. The Science Behind Electronics Recycling – Season 4, Episode 1

Only about 12.5 percent of electronic waste is currently properly recycled each year. Companies like Regency Technologies are working to increase this percentage by refurbishing, reusing, and recycling our old electronics. We visited one of Regency Technologies’ facilities to watch how 100,00 million electronics are recycled each year.
