Welcome to another episode of Sustainability Unveiled, where we dig into the truths, myths and hidden secrets of sustainability. I'm your host, ecovoice. Today, we're diving into a slice of sustainability that's both surprising and delightful. Let's talk about pizza. Did you know the love for pizza in America runs so deep? About 43 million people savor at least one slice daily. This beloved dish is not just a culinary delight, but also contributes a whopping $47 billion annually to the economy. And it brings us to our topic of discussion today pizza boxes.

Approximately a third of pizzas arrive at our doorstep in corrugated cardboard boxes. While these boxes crafted from sturdy corrugated cardboard ensure that our pizza stays fresh and warm, but they pose a significant recycling hurdle due to the residues they carry, notably grease and cheese. The resilience of these residues what we call fogs, fats, oils and greases renders the boxes unsuitable for recycling. But it's not all bad news. Researchers at Idaho National Laboratory, inl, and pizza enthusiasts are working diligently on this pizza box recycling conundrum. Their recent study showcases an inventive method to decontaminate cardboard using material separation capabilities, a method funded by the Defense Advanced Research Project Agency, darpa, designed to separate grease, cheese and other contaminants from pizza boxes. Aaron Wilson, the principal researcher for the experiment explained, material separation will be important for reducing waste across the energy and defense industries. To make specific separations possible, we need to first prove the overall concept of material separations, which is what this study accomplished. Their system uses a groundbreaking, environmentally friendly chemical, dimethyl ether DME and a lot of pizza to show how we can successfully recycle these resistant pizza boxes. The DME extraction operates in a closed loop that recycles the solution to clean new waste items. This means we're not just recycling, but doing so in a resource-efficient manner.

This research has vast potential for more than just pizza boxes. It signifies a new way of thinking about recycling. It not only draws attention to our food waste habits, but also shows how technological innovations can help us become more sustainable. Who knew that the humble pizza box could lead to such a transformative sustainability solution? From here on, each time you enjoy a slice of pizza, think about this. We're getting closer to a future where no part of that experience goes to waste, neither the pizza nor its box. That's all for this episode. If you're as excited as we are about these innovative green solutions, join us again next time as we unveil another layer of sustainability. Until then, continue to be the change you wish to see Be sustainable, be responsible. I am EcoVoice signing off.
