Tech solutions for reducing plastic pollution in oceans

January 25, 2024

Every year, about eight million tons of plastic waste end up in our oceans, according to the United Nations. This plastic waste not only poses a threat to marine life but also impacts our climate change and environment negatively. With the rise of new technologies, there are now innovative solutions to reduce ocean plastic waste. This article will delve into the different tech solutions that are currently being used to combat plastic pollution in our oceans.

Ocean Cleanup Technologies

The ocean cleanup technologies have become a beacon of hope in the fight against plastic pollution. These cleanup systems are designed to collect plastic debris from the water surface, aiding in the restoration of marine environments.

The Ocean Cleanup Project is one of the most renowned cleanup technologies. This project utilizes a floating barrier that moves with the ocean currents and collects plastic waste. The captured debris is then transported back to shore for recycling.

Another promising technology is the Bubble Barrier, developed by a Dutch start-up. This technology creates a barrier of air bubbles that ascends from the ocean floor, capturing plastic debris and guiding it to a collection system.

These ocean cleanup technologies play a critical role in reducing the amount of plastic waste in our oceans. However, they need to be complemented by other measures such as waste management and policies to reduce plastic production and consumption.

Microplastics Detection and Removal

Microplastics, tiny particles of plastic less than 5mm in size, pose a significant threat to marine life and human health. These microplastics are difficult to clean up due to their size, making them a particular challenge in the fight against ocean plastic pollution.

New technologies have emerged to detect and remove microplastics from the water. For instance, FRED (Floating Robot for Eliminating Debris) uses infrared sensors to detect and collect microplastics.

Additionally, researchers are developing microplastic filters that can be installed in washing machines to prevent the release of microplastics from synthetic clothes into the water system.

Addressing the microplastic problem is a vital component of the efforts to clean our oceans. It requires the adoption of these technologies at a global scale and the development of policies to manage and reduce microplastic pollution.

Waste Management and Circular Economy

Effective waste management and the adoption of a circular economy are crucial in the fight against marine plastic pollution. Waste management technologies contribute to reducing the amount of plastic waste that ends up in our oceans.

Smart bins and waste-to-energy systems are examples of technology being used to manage waste more efficiently. Smart bins use sensors to monitor waste levels, while waste-to-energy systems convert waste into usable energy.

On the other hand, a circular economy is an economic system aimed at reducing waste and making the most of resources. This regenerative approach is underpinned by the use of technology to design products that can be ‘made to be made again’, harnessing digital platforms to enable ‘access over ownership’ and sourcing materials in a way that regenerates natural systems.

Policies and Global Initiatives

While technology plays a vital role, it must be complemented with effective policies and global initiatives. International bodies like the United Nations have embarked on campaigns to raise awareness on ocean plastic pollution, and several governments have implemented policies to reduce plastic consumption.

Moreover, global initiatives such as the New Plastics Economy Global Commitment led by the Ellen MacArthur Foundation, aim to create a new system where plastic never becomes waste. This initiative brings together businesses and governments behind a common vision and targets to tackle plastic waste and pollution at its source.

In conclusion, technology offers innovative solutions to reduce plastic pollution in our oceans. From cleanup systems, microplastics detection and removal technologies, waste management solutions, and the adoption of a circular economy, technology is helping to turn the tide against ocean plastic pollution. However, these technologies need to be implemented at a global scale and supported by effective policies and initiatives to make a significant impact. Thus, the fight against plastic pollution in our oceans is far from over; it requires ongoing innovation, collaboration, and commitment.
