In this episode of the Supply Geek podcast, host Ben Thornton-Jones speaks with Joe Muscat, a packaging and sustainability expert with a background in chemistry, about the fascinating world of plastics and toothpaste tubes. They explore the history of plastics and toothpaste tubes, the evolution of packaging materials, and the complexities of recycling. Joe shares insights into the composition of toothpaste tubes, the challenges of recycling plastics, and the emerging alternatives to traditional materials. The conversation emphasizes the importance of sustainability and consumer responsibility in the context of packaging and waste management.

Takeaways

• Toothpaste tubes have evolved significantly over the years.
• The first toothpaste tubes were made of aluminum.
• Composite tubes made of plastic and aluminum are difficult to recycle.
• New mono-material toothpaste tubes are now being developed for recyclability.
• Plastics have a broad definition and include many types of materials.
• The recycling process involves sorting, cleaning, and melting plastics.
• Advanced recycling methods can turn waste plastics back into oil.
• Consumer behaviour plays a crucial role in recycling effectiveness.
