Imagine a world where every minute, the equivalent of a garbage truck full of plastic is dumped into our oceans and on beaches. This alarming reality threatens marine life, human health, and the future of our planet. Facing this challenge requires urgent action and innovative solutions. Initiatives led by associations, governments, and scientists are emerging to protect our marine ecosystems.
Some numbers for the UK: According to UK environmental research and conservation campaigns, UK households discard an estimated 100 billion pieces of plastic packaging every year, significantly contributing to plastic waste streams. Scientists also estimate that over 100,000 marine mammals and 1 million seabirds are killed annually by marine plastic pollution globally, and recent surveys have found plastic nurdle contamination in 84 % of UK Sites of Special Scientific Interest (SSSIs), including protected coastal and inland environments.

Everyone can take action, but large-scale measures require companies and governments. From public awareness to alternative materials and waste-collection technologies, this guide outlines strategies that tackle the root of the problem to preserve our oceans and secure a sustainable future for generations to come.
It is time to act and assume responsibility!
1. Public awareness initiatives on plastic pollution
The “Plastic Weather” project uses advanced technology to measure microplastic concentrations in real time. While it does not prevent pollution, it alerts populations to current levels and potential impacts.
Campaigns in schools, businesses, and media are essential to educate the public. Social media is ideal for sharing scientific information about the causes and consequences of plastic pollution on marine life and health.
2. Sustainable alternatives to single-use plastics
Reusable and durable materials, such as cloth bags and water bottles, are essential. Awareness campaigns encourage consumers to adopt these alternatives and phase out single-use containers.
Biodegradable and compostable materials
Supporting research and development of biodegradable and compostable materials—like dishware or cardboard bags—can replace conventional plastics without harming land or oceans.
Collaboration between research institutes, companies, and governments is key to accelerating the transition to sustainable materials.
Compostable plastics may not always degrade properly in real conditions and can contribute to pollution if not processed correctly.
Regulatory approaches
Subsidies and tax incentives can support companies producing reusable or biodegradable products. Taxes on single-use plastics discourage their use and reflect their environmental cost.
These measures foster the growth of sustainable alternatives and advance the circular economy, but strict standards are needed to prevent greenwashing.
3. Deposit-return schemes for plastic packaging
Deposit systems incentivize consumers to return bottles for a refund, reducing waste in bins. This approach, used successfully in multiple countries, significantly increases recycling rates and reduces plastic pollution.
Developing effective collection and recycling infrastructure ensures the success of deposit schemes while protecting wildlife and humans. Convenient collection points and optimised sorting processes are essential.
Reusing deposited and recycled packaging reduces plastic waste production.
4. Microplastic filters on washing machines
Installing microplastic filters on all new washing machines helps capture synthetic fibres released during laundry, a major source of ocean microplastics.
- Financial incentives and public-private partnerships could stimulate research and innovation in this area.
- This promotes effective, user-friendly microplastic filters integrated into appliances.
Public education campaigns are needed to raise awareness of microplastic pollution from synthetic textiles.
5. Rainwater harvesting systems
Governments can encourage rainwater collection for homes and businesses through subsidies. Collected water can be used for non-potable purposes, preserving drinking water reserves.
This reduces dependence on conventional water networks, which in turn lowers plastic bottle consumption.
6. Reusing treated wastewater
Modernised treatment plants can process wastewater for non-potable use. Dedicated distribution networks with rigorous quality control can supply industries, golf courses, and green spaces. Freshwater use is reduced, and public awareness helps promote environmental benefits, including less reliance on plastic bottles.
7. Gravity-fed water filters
Gravity-fed filters combined with activated carbon reduce pollutants by up to 99%, purifying tap, river, or non-potable water. This reduces plastic bottle use and protects human health and the environment.
8. The Manta: a global initiative
An historic UN agreement among 175 nations establishes a legally binding treaty to reduce plastic waste and promote a circular economy. The Manta, finalised by 2024, addresses the full lifecycle of plastics, from production to waste management.
- A major step in protecting marine ecosystems and human health.
- Governments must implement concrete measures to reduce plastic consumption, promote recycling, and develop sustainable alternatives.
- This coordinated global action is crucial to safeguard our planet for future generations.
Plastic in oceans and on beaches makes up 85% of overall pollution. In 2019, plastics generated nearly 1.8 billion tonnes of greenhouse gas emissions, or 3.4% of global emissions.
The so-called “7th continent,” a massive plastic accumulation between Hawaii and California, highlights the scale of the problem. In France, the AGEC law aims to eliminate all single-use plastic packaging by 2040.
It is time to act so future generations are not affected. Every small effort helps reduce the daily risk of ingesting plastics.
