Oceans of plastic

A new scientific project launched by the Tara Oceans Foundation has embarked on the schooner TARA to sail the nine largest European rivers, in order to follow the route plastic takes before it transforms into microplastic. The scientists are using a manta net, which allows them to take samples from the surface of the water due to the small mesh size, and capture microplastics in the open sea, on the coast or in rivers. The aim is to determine the types of plastic contained in European rivers…

Waterproofing, fire-proofing and non-stick coating. These technologies bring safety and comfort to our daily lives, but are based on chemicals called per and polyfluoroalkyl substances or PFAS. Nicknamed “forever chemicals”, these molecules are volatile - they can be emitted by the materials they are applied on and get released into the air. There, they can linger in the environment for decades and travel vast distances, accumulating in regions far from their initial site of emission. In the…

Plastic waste that accumulates in the ocean slowly deteriorates into smaller pieces. Scientists now estimate the amount of microplastics under the sea at 5000 billion tons, but the amount of nanoplastics remains unknown. That is why a French team decided to collect samples from the Mediterranean Sea to detect traces of nanoplastics. First, they concentrated the water by ultrafiltration and then used a dynamic light scattering technique to identify the nanoparticles. The final step was to resort…

Nanoplastics with a size of less than a thousandth of a millimetre are the finest form of plastic pollution. The Pepsea research project focusses on a type of nanowaste that is still poorly understood. Researchers chose Guadeloupe to study its impact on the environment. The island is exposed to the ocean and the North Atlantic Gyre making it an area of plastic accumulation. It is the perfect field of study for researchers who are going to explore its beaches and mangroves. They investigate the…

The aim of the PlastiGar study project is to monitor plastic pollution in the Garonne over three years to assess its impact on biodiversity in 14 separate sites. The film shows us how the researchers carry out measurements of microplastic concentrations in the river and how the first laboratory analyses are carried out. Starting in 2019, the project will be extended to study the presence of plastic in living organisms.

What happens to our garbage after it is dumped? Through the example of Delhi, the film explores the transformation of a piece of plastic waste into a resource, through filmed interviews with diverse “people of waste” living in the shadow of consumer society. It aims at making visible the myriad of professions that specialize in the collection, sorting, reselling, cleaning, shredding and transformation of waste, from the stigmatized garbage picker at the bottom of the chain until…
