The Fundamental Solution to Marine Plastic Pollution: The Key to Saving the Ocean is Not "Cleaning Up" but "Not Creating"

Introduction: What Should We Change Now

"Collect, Sort, and Recycle"—the traditional approach has not addressed the root cause. The NTNU research team concluded that to seriously stop the flow of marine plastic pollution, it is necessary to revamp values, systems, and designs from the "upstream" of production and consumption (Published on October 14, 2025).Phys.org

Focus of the Research: Only 3 Out of 52 Measures Were "Transformative"

An examination of 52 initiatives implemented in Norway since the 1980s (such as coastal cleanups, fishing net recovery, microplastic removal from sewage, introduction of alternative materials, sorting and awareness campaigns, and visualization of lost gear) revealed that most relied on recovery, substitution, and recycling, without delving into source suppression. Meanwhile, the measures with the highest potential for structural transformation were limited to (1) the municipal network KIMO, (2) the government's circular economy strategy, and (3) the International Ocean Panel. All are based on "pro-social/pro-ecological values," but limitations such as weak quantitative targets and deadlines were also identified.Phys.org

Proposal: Shift Values, Indicators, and Media Environment to "Ocean-Centric"

The research presents three pillars: (A) "Relational Environmental Thinking" that emphasizes the interrelationship between humans and nature, (B) Circular Economy, and (C) Ocean Stewardship. It calls for moving away from economic growth as the sole indicator and setting "ocean health" indicators such as water quality and biodiversity as progress markers, mandating reduction targets and deadlines at the early stages of value chains that generate disposables, and directing resources to grassroots zero-waste initiatives and small businesses. It also highlights the need to correct the value bias in the information received daily by reducing the proportion of profit-driven advertisements and increasing public/non-profit messaging.Phys.org

Overall Picture of the Project: What "Sweet Spot" Aims For

NTNU's "Sweet Spot" project explores interdisciplinary "effective points" through machine learning and UAV (Unmanned Aerial Vehicle) data collection, lab analysis of degradation rates, identification of behavior change parameters, and design of supply chains and business models. It is an approach to determine "where to press for the entire system to move."Phys.org

Global Context: Stagnation in Treaty Negotiations and the Role of "Cleanup"

As of August 2025, the UN's global plastic treaty negotiations have not reached an agreement and have been postponed to the next meeting. The inflow is estimated at 23 million tons annually, with the potential to double by 2030. While expanding local cleanups and trash traps is important, they tend to only alleviate the "symptoms" of pollution. True effectiveness requires a multi-layered strategy that simultaneously advances production suppression, hazardous chemical management, design review, and waste management.Phys.org

Common Assertion "More Plastic Than Fish by 2050"—How to Distance from the Fact

The phrase "by 2050, the weight of plastic in the ocean will exceed that of fish" has spread widely, but it is based on an initial estimate from 2016 with noted uncertainties. While effective as an expression to convey the seriousness of the issue, it is crucial to update policies with the latest data and targets.wwf.org.uk

SNS Reactions: Three "Discussion Clusters"

1) Support for Moving Away from Overemphasis on Individual Actions
The argument that "focusing solely on individual efforts delays reforms on the institutional and industrial sides" is strong on social media. While linked to discussions in climate research reporting, it is widely shared as a "structural transformation" orientation common to the plastic issue.Reddit

2) Calls for Producer Responsibility (EPR) and Strengthened Regulations
Opinions such as "producers should bear the cost of pollution" and "strengthen regulations on disposables and recovery obligations" are gaining support in the community.Reddit

3) Pragmatic Discussions on Consumer Choices and Regulations
Debates continue on "how realistically can we reduce" regarding LCA of paper bags vs. plastic bags, the usage criteria for reusable bags, and plastic use in vegan lifestyles. There is a need for smarter designs considering the side effects of regulations and alternatives.Reddit

4) Spread of Awareness and Solidarity
Official accounts like the UN continue to call for action with hashtags like #SaveOurOcean, visualizing both crisis and hope.Facebook

Where to Start: Editorial Suggestions Checklist

• Reduce Upstream: Set clear reduction targets (%) and deadlines (years) for the use of primary materials and resins. Companies should disclose internal KPIs in terms of "weight," "primary plastic rate," and "redesign rate."PLOS

• Stop with Design: Design packaging with refilling and reuse in mind, mono-materialization, and transparency of additives.

• Support the Community: Subsidize and prioritize procurement for zero-waste stores and reuse platforms.Phys.org

• Change the Message: Reassess the ratio of commercial advertisements and visualize public/non-profit awareness (do not discard, reuse, return).Phys.org

• Strategize Cleaning: Operate beach cleanups and trash traps as "citizen science" that connects data acquisition and policy proposals.Phys.org

Conclusion: Align Values with the "Ocean"

The values behind actions ultimately shape institutions and markets. NTNU's research calls for a pivot from "using the ocean for the economy" to "aligning the economy around ocean health"—to fully implement this in indicators, advertising, design, and investment. Changing the messages we are exposed to daily and the design of what we handle every day is the shortest path to reaching the ocean.Phys.org
