Plastisphere Podcast

Follow me on a journey into the world of synthetic polymers, their impacts on nature and ourselves, and the global quest to tackle plastic pollution. Listen here:

Talk at webinar series #microplastinar

How reliable are infographics and the figures and facts we find online? What are the current dynamics of the media landscape? And how could they become more sustainable?

These are some of the questions I covered in a talk on plastics in the media for the Limnoplast plastic webinar series.

I highly recommend to check out this interactive web-series, featuring a great line-up of speakers to take a closer look at the wicked problem of plastic pollution.

Podcast on Soil Ecology

Our podcast Life in the Soil brings you the insights and voices of some of the world’s best soil scientists. Learn about soil biodiversity, why it matters, and how we can protect it. The series is a collaboration with the Rillig Lab, funded through the BiodivERsA project Digging Deeper.

Plastisphere Ep.10: Chatting about Individual Impact

When it comes to solving the issue of plastic pollution, who would you say is responsible? Is it individuals like you and me, is it the corporations that produce plastics or products made from it, or is it the government with its rules and regulations?

Plastisphere Ep.9: The Discovery of Plastic Pollution

Plastic pollution seems to be a pretty new issue, right? In the past few years, the topic has been all over the media. But if you explore the history of science, it turns out that the problem really isn’t all that new.

Ein fast unbekanntes Flugobjekt

Plastik schwimmt nicht nur im Wasser und verschmutzt Flüsse, Böden und Ozeane. Erste Forschungsergebnisse zeigen, dass es auch fliegen kann. Was wissen wir über Mikroplastik in der Luft? Drohen Folgen für die Gesundheit – und kann man sich schützen?

Plastisphere Ep 8: Plastics in times of the coronavirus

For this episode, Anja tried something new: She asked listeners, researchers and podcasters to send her audio comments on what is happening now during the coronavirus pandemic. In this episode, you’ll hear some of the messages that arrived in her inbox the past weeks.

Plastik im Schnee

Beitrag in Deutschlandfunk „Forschung aktuell“ hören:

Are bioplastics a greener alternative to conventional plastics?

Confusion among terms like bioplastics, bio-based and biodegradable plastics makes it hard to discern — and make — the environmentally responsible choice. Article on Ensia, republished by Undark Magazine, The Revelator, The Wire, and others.

Plastisphere Ep.7: Confused about bioplastics?

What happens if bioplastics end up in the environment? In this episode, Anja takes a closer look at synthetic polymers marketed as more environmentally friendly. Can they contribute to a healthier planet, and in what way?

Plastisphere Ep.6: Traces in the soil

Plastic pollution also affects the soil, the thin layer of ground that feeds all of us. For a long time, this terrestrial plastic has been overlooked. Now scientists are starting to investigate the extent and impacts of plastic pollution in the soil and in the ground. What do we know about them?

Kommt nicht in die Tüte!

Nathalie Mayroth war im indischen Bundesstaat Maharashtra, in dem auch die 20-Millionen-Stadt Mumbai liegt. Seit einem Jahr ist dort Einwegplastik verboten. Wie gut wird das jetzt durchgesetzt? Darum geht es in dieser eindrücklichen Reportage. Mehr lesen bei piqd

Wie das Ocean-Cleanup-Projekt ein komplett unbekanntes Ökosystem in Gefahr bringt

Das Projekt „The Ocean Cleanup“ des jungen Niederländers Boyan Slat hat ebenso leidenschaftliche Unterstützer wie Kritiker. Zu letzteren gehört die Biologin Rebecca Helm, die in The Atlantic von einem faszinierenden Ökosystem berichtet, von dem ich zuvor noch nie gehört hatte: Lebende Inseln, die über die Meere treiben, für die die Müllbarrieren des Ocean Cleanup eine …

Plastisphere Ep.5: Message from Midway

Chris Jordan has taken some of the most iconic pictures to shape our image of plastic pollution. He traveled to Midway Island on his quest to photograph the evasive „Great Pacific Garbage Patch“, which is really a soup of microplastics. There, he documented albatross chicks who had died with their guts full of plastic. His images went viral, but they also haunted him so much that he decided to return to the island. In this episode of the podcast, Chris tells Anja how working on his film „Albatross“ transformed him and his view on tackling plastic pollution.

Plastisphere Ep.4: Plastic vs. the Climate?

Plastic pollution might be the most visible environmental issue we face today. But there are other kinds of pollution, and they are far harder to see. One of the most dangerous is the huge amount of greenhouse gases that we emit into the atmosphere. In this episode, Anja explores the connections between plastic pollution and climate change.

Klimafaktor Plastik?

Plastisphere Ep.3: Waste picker economies

Anja calls up Dr. Jenna Jambeck and Amy Brooks from the University of Georgia on a research trip in Vietnam. In many Asian countries, a booming economy is coupled with more people using throw-away items. Informal recyclers and waste pickers who have traditionally sorted the waste cannot keep up. But, like millions of people around the world, they depend on waste as a resource for their livelihoods. How can the systems be reformed without leaving the people behind? To find out, Anja calls Dr. Sonia Maria Dias, a garbologist from Brazil.

Plastisphere Ep.2: Plastic, the size of a virus

This time on Plastisphere, Anja goes on a lab tour with Alexandra ter Halle from Paul Sabatier University in Toulouse. The chemist and her team were the first to detect nanoplastic in the open ocean – plastic so small that it is comparable in size to a virus. What do we know about these very tiny pieces, and how do researchers try to detect and understand them?

Reinigungsaktion im Pazifik

Ein sechshundert Meter langes Rohr, darunter hängt ein Vorhang – diese Konstruktion soll von San Francisco aus aufs offene Meer kommen. Dort soll sie als Plastikbarriere ihren Dienst aufnehmen. Der Erfolg des Projektes ist umstritten – und Kritiker befürchten sogar Beeinträchtigungen des Ökosystems. Beitrag lesen. Deutschlandfunk | Forschung aktuell | 7. September 2018 | 5 …
