   How [Not] To Make A Plastics Treaty - The Mysterious Midnight Meeting

   It's 2026, and we still don't have a plastics treaty. Will we get one, what kind, and when? All of that is up in the air at this point. And after the failed round of negotiations last summer in Geneva, some strange insights emerged: During the last night, a mysterious midnight meeting took place, seemingly to take down the Chair, the person running the negotiation process between states. And - coincidence or not - later in the fall, the Chair did actually step down. Now a new Chair was just elected - showing that if countries want, they can get things done with a vote. In this episode, Magnus Lovold of NAIL, the Norwegian Academy of International Law and a long-time observer of the process, shares his research on that middle-of-the-night meeting and chats with Anja about what happened since, and what might happen next. How many times will the diplomats need to meet until they can conclude an agreement?

   Tackling Plastic Production: Why and How to Do It

   It's the elephant in the room: The growth of plastic production and how that contributes to pollution. In this episode, we're taking a look at why it's important to not only tackle the waste plastic causes, but also the source of the issue itself. Anja discusses this with Melanie Bergmann, a marine biologist at Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research and a plastic pollution researcher for more than a decade, and Kristian Syberg, an environmental scientist and planner from Roskilde University. Both are members of the Scientists' Coalition for an Effective Plastics Treaty. Sources mentioned: - Cowger et al.

   Reuse, Reuse, Reuse! How a Tradititional Concept Can Help Reduce Plastic Waste

   You’ve probably heard the mantra of reduce, reuse, recycle. And oftentimes, it’s that last word, recycle, that we think of when looking to solve plastic pollution. But the order of that mantra has a deeper meaning, it’s a hierachy, sorted by priorities. So to reduce the waste we produce, the first and best way is to reduce what we use. If that’s not possible, the second best option is to reuse, to repair, or repurpose. Only if if that is not viable anymore should we consider recycling. We already discussed these steps towards a circular economy in our previous episode. In this follow-up, we’ll take a look at reuse with Froilan Grate, the Asia-Pacific Director of the Global Alliance for Incinerator Alternatives (GAIA), based in the Philippines, and Salisa Traipipitsiriwat from Thailand, a Senior Campaigner at the Environmental Justice Foundation, also part of GAIA. Intro in Thai by Salisa.
