MEPA is the ' apex body responsible for the prevention, controlling, and managing pollution in Sri Lanka’s marine environment and is the enforcing agency of the laws and provisions stipulated in the Marine Pollution Prevention Act No.35 of 2008'.

Marine Litter Solutions.com showcases the Global Plastics Alliance's work toward solving ocean pollution and reducing ocean plastic. Building on previous efforts in individual regions, the world plastics organizations that have joined the Global Plastics Alliance and signed the “Global Declaration for Solutions on Marine Litter” have agreed to focus projects to address marine litter. Through their programs and partnerships in nearly 20 countries, they are active in increasing recycling and recovery, and increasing ocean pollution clean-up and marine litter prevention programs.

Marine Watchdogs focuses on the health of the ocean and the food products that come from it. A member-based nonprofit action company, their mission includes research, education and active projects like seafloor cleanup events. They aim to engage the public and enable ways for people to get involved in ocean ecology via seabed survey and seafloor clean-ups. Their multiple activities include: conducting toxicology tests, alerting the public to contamination issues, conducting marine bio fieldtrips, providing educational resources, and running campaigns aimed at reducing single-use plastic waste and agricultural chemical run-off.

Set up with the mission of inspiring people 'to take action for plastic free beaches, oceans and rivers', Mi Moana hosts monthly beach cleanups along the Costa del Sol coast line in Andalucía, Spain. They have a triple goal: to educate, to conserve and to regenerate the ecosystems in the ocean.

Mind Your Plastic’s mission is to solve plastic pollution in Canada. Mind Your Plastic creates change by advocating for Canadian businesses to take impactful steps towards eliminating their plastic pollution footprint, driving towards implementation of changes with government, producers, recyclers and consumers, and supporting and implementing programs to clean Canadian coastlines including their annual Circular Economy Ambassador Program.

Mission Green Sri Lanka engages local communities and especially young people in environmental projects, including mangrove planting, beach and river cleanups to combat plastic pollution, amongst other projects on land and sea.

Mr. Trash Wheel is a stationary vessel positioned in the Baltimore River to catch marine debris before it reaches the harbour. Powered by its water wheels and solar panels, it is operated by a human crew.

Neptune's Army of Rubbish Cleaners are volunteer divers who collect marine waste via cleanup dives in the UK. They work at raising awareness of the impact of marine debris, and on finding collaborative solutions to the problem of pollution in the oceans. With over 2000 cleanup dives, they are an award-winning conservation group.

The NetTag approach to the problem of marine litter derived from fisheries combines two different types of preventive measures: new technology to prevent lost gears; and awareness actions to promote best-practices for on-board waste management. NetTag is developing new technologies to track fishing gears in case gears got lost, fostering a reduction of lost gears. The technology involves low cost, miniature and environmental-friendly acoustic tags and acoustic transceivers for uniquely localization (with fisher’s personal ID) of lost gear and an automated-short-range robotic recovery system. This is an active project co-ordinated by Ciimar in Portugal.

Nofir recycles discarded equipment from fishing industry and fish farming industry all over Europe and beyond. They collect the material, such as fishing nets, ropes, and tarpaulins from various sites, including fish farms and recycling facilities. The material is transported to their factories in Lithuania and in Turkey, where it is dismantled and recycled, producing new products like socks, furniture, carpets, swimsuits, baskets etc. This is both resource-friendly, and also reduces the amount of ghost gear in the oceans. In 2012 Nofir received EU funds for a project to establish a European system for collecting and recycling discarded equipment from the fishing and fish farming industry. Their business has expanded to 20 countries around the world.

The main aim of the Nordic Coastal Cleanup network is 'to mobilize volunteers and pick litter from our beaches along the coast and inland along rivers and lakes throughout the Nordic countries'...and 'to fill the knowledge gap about the sources of marine litter in the Nordic countries by conducting beach monitoring and data collection'. There are eight organisations involved in the network: CSR Greenland, Keep Denmark Tidy, Keep Norway Beautiful, Keep Sweden Tidy, Arctic Marine Conservation Crew (Iceland), Keep the Archipelago Tidy, Ringrás (Faroe Island) and Städa Åland.

As a grassroots community environment non-profit movement, Ocean Blue Project's mission is to rehabilitate and conserve the world's oceans, beaches, and rivers through beach and river clean-ups. They also provide solutions to keep pollutants from entering ecosystems through collaborative community-driven service learning projects and youth education, specifically their Blue Schools initiative which is an ecology- and sustainability-based K-12 curriculum, empowers students—and communities—to become stewards of their beaches, streams, rivers, and ocean.
