WE ARE CLEANING THE OCEANS

- This graph exclusively shows **plastics floating** at the ocean surface.

- These can be cleaned relatively easily.

- But what about those floating at various depths in the **water column**?

- And those deposited on the **seabed**?

- And those stranded on **beaches**?

QUESTION 3 — WHAT IS THE SOLUTION ?

* What are supplementary solutions if **technologies** in ocean cleaning **are not sufficient** ?

* But anyway, why cleaning the **oceans** if we are **continuously filling** them with plastics?

* Shouldn't we better solve the problem at the source, that is, **on land**?

# SOLUTION: REVIVING ECONOMIC GROWTH?

* Some economists believe that **economic growth** is *The* solution.

* They rely on the theory of the **Environmental Kuznets Curve** (an equation exclusively relying on **GDP per capita**):

1. In the **growth phase** of a country, inhabitants see their income increasing → As a result, they consume more → It generates more plastic waste (**inadequately managed** due to the lack of effective waste treatment system)

2. Beyond a certain level of income per inhabitant, the amount of **plastic waste** per inhabitant **inadequately managed** would start to **decrease**:

3. – **because populations** having access to better life conditions start to worry about the quality of their existence and **demand environmental improvements**.

– **because a growing economy** has more financial resources **to invest** in waste treatment technologies, in ocean cleaning technologies, etc.

SOLUTION: CONTROLLING CORRUPTION AND LOBBY?

- Corruption control policies including control of financial and industrial lobby
  (Corruption = when the public power is used for private gain, including petty and grand forms of corruption and the State is captured by elites and private interests (definition from the World Bank)).

- Urbanisation

- Culture, mentalities and moral values in each region of the world

- International tourism on small islands

- GDP per capita

## CONCLUSION

* The growth of GDP per capita will not create sufficient investment capacity in waste treatment infrastructures to solve the problem of plastics.

* Non-technological solutions such as corruption & lobby control policies and education are able to reduce inadequately managed plastic waste. They must be part of implemented interventions.

To maintain our current appetite for natural resources, we would need the equivalent of 1.7 Earths

* **Scenario 4.1:** Reducing by 50% plastic waste inadequately managed in the top 20 most polluting countries.

* **Scenario 4.2:** capping **in all countries** the individual generation of waste to 1.2 kg/day/inhabitant and the percentage of plastics in these waste to 11% (both figures = the world average). How to reach that?

- Installing public recycling bins in the street.

- Developing return and deposit systems for bottle reuse.

- Designing laws to make *Extended Producer Responsibility* compulsory for plastic products.

- Subsidise (and/or tax exemptions) for repair cafés offering collaborative workshops to learn how to repair broken devices.

- Taxing products designed with planned obsolescence.

COMBINING SOLUTIONS

* We need to take measure **upstream** of the problem, **not downstream**.

* Focusing all efforts on 1 **downstream solution** – ex. ocean cleaning technologies – will not be **enough**.

* We must **combine several strategies** :

**Upstream strategies** : education, control of corruption and lobby, repair cafés, prohibit single use plastic products (bottles included!), etc.

**Middle strategies** : return and deposit systems for bottle reuse, recycling, etc.

**Downstream strategies**: ocean and beach cleaning, filtering rivers in estuaries, etc.

<table><thead><tr><th></th><th></th><th></th></tr></thead><tbody><tr><td>Upstream</td><td>Solutions at the source of the problem</td><td></td></tr><tr><td>Middle solutions</td><td>Preventive measures</td><td></td></tr><tr><td></td><td>Avoid and reduce waste production</td><td>1. Awareness raising campaigns and collaborative strategies (Benkler, 2011; Ostrom, 2010) to encourage households to reduce waste generation and overconsumption behaviors in general.<br>2. Inciting industries to substitute plastic materials with aluminum, glass, bio-plastics, etc.<br>3. Nurdle spillage prevention in plastic factories (nurdles are pre-production microplastic pellets).<br>4. Fiscal instruments and compulsory legislation to reduce the amount of packaging.<br>5. Compulsory legislation to ban micro beads in cosmetics or in toothpastes, or to ban single-use plastic products, etc.</td></tr><tr><td></td><td>Reuse or repair old products</td><td>6. Returnable glass or PET bottle systems.<br>7. Moving from an economy of ownership to one of service functionality.<br>8. Online systems designed to help to share, trade, exchange, lend or rent second-hand products between neighbors, including plastic products.<br>9. Legislation forbidding planned obsolescence of products.<br>10. Fiscal rules that favor longer lasting products, etc.</td></tr><tr><td></td><td>Recycling</td><td>11. Recycling in closed cycles (e.g., recycling of plastic bottles, plastic bags, etc.).<br>12. Legislation for compulsory extended producer responsibility in the plastic industry.</td></tr><tr><td></td><td>Improvement in waste collection infrastructure</td><td>13. Invest in landfill sealing to avoid plastic waste leakages through rain, waterways or wind, from dumps or open, uncontrolled landfills, where waste is not suitably contained.<br>14. Invest in public garbage cans, waste collection system, awareness raising to reduce littering, etc.</td></tr><tr><td></td><td>Incineration</td><td>15.
