Innovative solutions to combat marine pollution

From 1990 to 2015 alone, it is estimated that up to 100 million tonnes of garbage flowed into the sea. Credits: Brian Yurasits via Unsplash

A PET bottle floating in the sea. Turtle stomach. COVID-19 Mask Dancing in the Waves: Few images are as unpleasant to look at as images showing pollution in the ocean. And environmental problems are so urgent that few are manifested in the consciousness of the general public. “Most people have an emotional connection to the ocean. They consider marine pollution to be an attack on the place they’ve been waiting for,” said Heleon’s Institute for Coastal Systems Analysis and Modeling. Said Nicoleta Bellow, a marine scientist at. From 1990 to 2015 alone, an estimated 100 million tonnes of plastic waste flowed into the ocean. In that sense, this study fits into the United Nations Decade of Marine Science for Sustainable Development, which began this year to emphasize the sustainable use of the ocean.


The new overview survey is the first to document most of the existing solutions (technologies and methods) for prevention, monitoring, and cleanup with innovative approaches. Looking to the future, Nicoleta Bellow and the international team: Camilo A. Arieta Giron, Joan Cunning Claude, Chiara Gambardera, Constantinos Calanzaros, Stephanie Kemna, Karsten Remen, Joao Monteiro Helmholtz-Zentrum Hereon’s co-authors and participants include the Italian National Research Council, the Center for Marine Environmental Sciences, the National Institute of Technology of Athens, the Smithsonian Institute, and Marine Robots. Engineering is included.

Explore all categories

The team looked at all categories, from crowdfunding projects to research databases. Scientists have researched nearly 200 solutions that plan to utilize drones, robots, conveyor belts, nets, pumps, or filters.

To date, many developers have used similar technical approaches, but there are signs that the next generation will increasingly rely on a wide variety of solutions. It will increasingly integrate machine learning, robotics, automation, big data analytics and modeling.While Scientific community Studies show that the focus is primarily on surveillance, with NGOs primarily focusing on prevention, and most cleanup solutions are the result of the cooperation of different players.

Rarely implemented

Still, most projects never go beyond the development stage. Few solutions have become a technical reality or have been commercially available. The authors of this study point out that many issues need to be considered to the end, going beyond the planning stage. “Integration of solutions into policy guidelines should be promoted politically to establish the industry of the future,” Bellow said. Based on research and data collection, analysis reveals how thin and difficult to access such information. Most solutions (approximately 60%) are primarily for monitoring and have been developed over the last three years.

Policy recommendations

This study addresses the limitations of existing solutions and the challenges of developing new ones. It also recommends political action. In addition to international cooperation between researchers and national environmental departments and institutions, scientists recommend defining their respective standards. Solution, Each size, effectiveness, environmentally friendly footprint-based evaluation, etc. This allows you to create new funding programs that further develop both existing and new solutions with the help of global databases. “This is a way to encourage researchers and political decision makers to create a sustainable approach to keeping marine debris under control. We want to leave clean waters for future generations. I think, “said Nicoleta Bellow.

The study is published in the following journals: Natural sustainability..
