Turning the Tide on Plastic 🌊🧴 How Shipping Can Reduce Marine Waste

My name is Davide Ramponi, I’m 20 years old and currently training as a shipping agent in Hamburg. On this blog, I take you with me on my journey into the fascinating world of shipping. I share my knowledge, my experiences, and my progress toward becoming an expert in the field of Sale and Purchase – the trade with ships.

Today’s topic touches every ship, every sea, and every port of call—but too often floats just beneath the radar. We’re talking about plastic pollution in the maritime industry. 🧴🌍

While most discussions around sustainability in shipping focus on fuels, emissions, and energy efficiency, the issue of plastic waste at sea remains a silent crisis. Every year, millions of tons of plastic find their way into oceans—and although shipping is not the largest source, our industry plays a role, and we have the power to make a difference.

So how exactly is plastic waste entering the marine environment? What rules exist to combat it? And what are some of the most effective—and innovative—solutions being deployed onboard and across the maritime supply chain?

Let’s set sail for cleaner seas. ⚓

The Scope of Maritime Plastic Pollution 🧴🌊

According to UNEP, an estimated 11 million tons of plastic enter the oceans each year. That’s roughly one garbage truck of plastic dumped into the sea every minute. While land-based sources account for the majority of marine debris, the shipping industry still contributes between 5–10%, primarily through:

• Garbage mismanagement

• Lost cargo (containers, fishing gear)

• Improper disposal at sea

• Legacy habits and poor oversight

And the consequences?

💡 Plastic pollution doesn’t just harm the environment—it damages reputations, invites penalties, and increases regulatory pressure.

Regulations and Global Frameworks 📜⚖️

The fight against maritime plastic waste isn’t new—but it’s evolving.

🚢 MARPOL Annex V – The Core Regulation

• Prohibits disposal of plastics at sea

• Requires Garbage Record Books and Garbage Management Plans

• Applies to all ships >100 GT or carrying >15 people

• Updated in 2013 to cover all plastics, including packaging and fishing gear

⚠️ Violation can result in heavy fines, detention, and reputational damage.

🌍 IMO Action Plan on Marine Litter (2018–2025)

• Enhances enforcement of MARPOL V

• Promotes zero discharge from ships

• Encourages fishing gear tracking and port reception improvements

🇪🇺 EU Port Reception Facilities Regulation

• Requires ships to deliver waste at port, not at sea

• Simplifies port procedures and harmonizes fees

• Applies to all EU ports and foreign vessels docking there

✍️ Basel Convention (and Plastics Amendment)

• Governs transboundary movement of plastic waste

• Aims to prevent dumping of contaminated or non-recyclable plastics in developing countries

🧾 Compliance is now as much about documentation as it is about disposal.

Best Practices Onboard for Waste Management 🛠️🚮

Reducing plastic waste starts with shipboard habits. Here are some of the most effective day-to-day practices:

✅ 1. Segregation and Storage

• Use color-coded bins for plastics, organics, metals, etc.

• Train crew in proper separation and labeling

• Store plastics in designated sealed containers

✅ 2. Inventory Control and Reduction

• Audit plastic packaging on provisions and spare parts

• Work with suppliers to reduce single-use items

• Use bulk or reusable containers where possible

🍽️ Replacing bottled water with filtered dispensers has saved some vessels over 1,000 plastic bottles per voyage.

✅ 3. Document Everything

• Maintain up-to-date Garbage Record Books

• Keep evidence of port waste deliveries

• Share logs with charterers or ESG auditors if requested

✅ 4. Crew Training and Culture

• Make plastic reduction part of onboarding and safety drills

• Recognize and reward waste management excellence

• Include sustainability in company KPIs and fleet performance reviews

Innovative Technological Solutions 🚀♻️

Technology is playing an exciting role in reducing maritime plastic pollution.

🔋 Smart Compactors

Modern marine waste compactors:

• Compress plastic volume by up to 85%

• Integrate with digital logging systems

• Reduce storage space and increase recycling viability

🌊 Plastic Collection Systems

Some vessels are now equipped with marine litter skimmers or nets to collect floating debris during operations—especially in coastal or port areas.

⚓ In 2022, a Japanese coastal vessel collected over 3 tons of plastic in its first year of service using a built-in surface skimmer.

📡 Digital Waste Monitoring

Software platforms allow operators to:

• Monitor waste generation per voyage

• Benchmark vessel and fleet performance

• Automatically generate compliance reports for IMO and ESG standards

🔄 Onboard Recycling Units

While still emerging, some ships are trialing small-scale plastic reprocessing systems—melting or shredding waste into reusable components.

Industry Case Studies and Initiatives 🌐🌟

🚢 Maersk – Zero Plastic Packaging Pilot

Maersk has launched programs to:

• Eliminate single-use plastics from shipboard operations

• Work with suppliers to reduce packaging

• Switch to compostable and recyclable alternatives

Result:

Up to 90% reduction in plastic consumption across test vessels.

🚢 MSC Cruises – “Plastic Reduction Program”

• Banned over 40 single-use plastic items onboard

• Replaced with bamboo, paper, or refillable alternatives

• Partnered with Ocean Cay Reserve for plastic-free island logistics

🌎 The Ocean Cleanup – Partnership with Shipping

• Cargo vessels carry interceptors and collection units

• Use idle voyage segments to support marine litter recovery

• Companies like Maersk and CMA CGM support logistics and infrastructure

🚢 NYK – Shipboard Waste AI Monitoring

• Trialing AI-powered sorting and analysis systems

• Monitors bin contamination and crew compliance

• Aims to reach zero plastic discharge across entire fleet by 2030

Challenges and Barriers to Progress 🚧

Despite progress, several hurdles remain:

🏗️ 1. Port Reception Inconsistencies

• Not all ports offer adequate recycling facilities

• Fee structures discourage full waste discharge

• Risk of illegal dumping remains in some regions

💸 2. Cost vs. Incentive

• Recycling and advanced waste systems have high upfront costs

• Many owners prioritize fuel savings over waste systems

• Lack of direct financial return discourages investments

🔍 3. Crew Turnover and Training Gaps

• Waste management requires consistent education

• Short contracts and mixed language crews can slow implementation

Strategic Recommendations for Reducing Plastic Waste 🧭

Whether you're managing a ship, chartering a voyage, or building company policy, here’s how to move forward:

✅ 1. Build Waste Plans into ISM Systems

Make plastic control a core part of your safety and environment management procedures—not just an afterthought.

✅ 2. Collaborate with Ports and Suppliers

• Ask for low-plastic packaging

• Request port waste reports before arrival

• Share best practices within your shipping alliances

✅ 3. Leverage Digital Tools

• Use MRV-style software for waste tracking

• Link plastic waste data to ESG and CII reporting

• Offer charterers visibility into waste KPIs

✅ 4. Think Circular, Not Linear

Explore circular options like:

• Onboard recycling

• Take-back packaging schemes

• End-of-life gear reprocessing (e.g. ropes, nets)

♻️ Waste is not just something to dispose—it’s something to manage with purpose.

Conclusion: A Cleaner Sea Starts on Deck 🌍🛳️

Maritime plastic waste is one of the industry’s most visible—and solvable—challenges. With the right regulations, technology, crew culture, and cross-sector cooperation, we can turn the tide on pollution and show the world that shipping is serious about sustainability.
