How Ports Turn Circular Ambition into Industrial Reality

Port authorities can turn circular economy ambitions into viable industries by connecting infrastructure, investment, regulation and industrial partnerships.

In 2020, the European Commission adopted the Circular Economy Action Plan as one of the main building blocks of the European Green Deal, aiming to double the circular material use rate of the European Union (EU) by 2030. The Action Plan aims to promote more sustainable production and consumption by keeping products and materials in use for longer, reducing waste and supporting innovation in circular business models.

Within this broader policy framework, ports also have an important role to play. They concentrate industry, energy, logistics and international supply chains in one location, which is why the European Sea Ports Organisation sees them as natural hubs for circular value chains. The scale is considerable: the Antwerp-Rotterdam-Rhine-Ruhr area alone accounts for 40 percent of EU petrochemical production and 350,000 direct jobs. The material flows that must become circular already pass through the port gates.

The question then becomes: what can a port authority do to help circular industries move from promising concepts to commercially viable businesses?

The approach developed by the Port of Antwerp-Bruges starts from the idea that circular industries need more than industrial land. They require an ecosystem in which infrastructure, industrial partners, logistics, knowledge, finance and public authorities work together to support industrial development. NextGen District is the practical implementation of this vision.

Creating the Right Conditions

Located on the former General Motors site, NextGen District is a plot of 88 hectares being developed as a dedicated environment for circular industry.

Three mechanisms bring the ecosystem together. First, NextGen Demo, a plug-and-play zone of more than two hectares with shared utilities, offers pilot projects a place to prove their technology in a real port environment before scaling up. Second, the port authority connects newcomers with the surrounding cluster for feedstock, offtake, utilities and residual heat. Third, it guides projects through permitting and public funding, from Flemish innovation support to the EU Innovation Fund.

The pipeline shows the result and the stage each project has reached. Bolder Industries will convert more than six million end-of-life tyres a year into nearly 18,000 tonnes of recovered carbon black and 21,000 tonnes of circular oil, backed by a €32 million Innovation Fund grant; its permits are in place, and contractor selection is under way. PureCycle chose the district for its first European polypropylene purification plant, a project backed by a €40 million EU Innovation Fund grant, with a designed capacity of 59,000 tonnes a year. TripleW started with a €5 million demonstration plant at NextGen Demo, turning food waste into lactic acid for biodegradable plastics, and now holds an environmental permit for a full-scale plant processing 100,000 tonnes of food waste a year.

Outside the NextGen District, other projects are also advancing towards closing the loop. In 2025, Indaver opened its new plastics2chemicals plant, investing €105 million to recycle polystyrene8 which is then sent to INEOS Styrolutions for further processing. Further, SynPet Technologies is close to investing €300 million to recycle up to 250,000 tonnes of untreated, mixed plastic waste into circular naphtha.

Building on Existing Strengths

The concept behind NextGen District builds on strengths that already exist in the Port of Antwerp-Bruges.

NextGen District does not start from scratch. The Port of Antwerp-Bruges handles around 290 million tonnes of international maritime cargo a year, employs some 164,000 people directly and indirectly and generates more than €21 billion in added value. It is home to Europe’s largest integrated chemical cluster, with steam crackers from TotalEnergies and BASF, a brand-new, world-scale ethane cracker from INEOS to be commissioned soon, more than 1,000 km of pipelines and nearly 10 million m³ of third-party liquid storage. Sixty percent of Europe’s purchasing power lies within 500 km of Antwerp, reachable by barge, rail, pipeline and road.

For a circular company, this matters. Feedstock can be aggregated through the port’s logistics network. Industrial customers for recycled carbon black, polymers or chemical building blocks sit within the same cluster, and utilities, engineering services and research institutions are already in place. Industrial symbiosis works over short distances.

Beyond Infrastructure

Land and connectivity are necessary but not sufficient. Three other conditions decide whether a project gets built.

The first is regulation, where two barriers stand out. One is moving feedstock inside Europe: mixed plastic waste for chemical recycling needs prior consent from the authorities of each country involved to cross an internal EU border. For years, exporting plastic waste outside the EU was often simpler. The revised Waste Shipment Regulation restricts such exports; having closed the door outwards, Europe should now open the doors between its member states.

The other is how recycled content is counted. Chemically recycled molecules are mixed with fossil feedstock in existing plants, so they can only count towards the targets of the Packaging and Packaging Waste Regulation (PPWR) through mass-balance accounting. The rules for this accounting, due by the end of 2026, will decide how much output qualifies as recycled and could unlock even more investment in chemical recycling.

Permitting procedures also require careful coordination, particularly where projects combine different industrial activities and regulatory frameworks. Early dialogue between project developers and the relevant authorities can help identify potential challenges before formal procedures begin.

Developing circular industry is not only about technology but also about creating regulatory, financial and organisational conditions that allow innovation to mature into competitive industrial activity.

Access to finance is equally important. Circular industrial projects generally involve substantial upfront investment and long development timelines. Bringing innovative technologies to commercial scale therefore depends on a combination of entrepreneurial initiative, public support mechanisms and private investment.

These experiences underline a broader lesson. Developing circular industry is not only about technology but also about creating regulatory, financial and organisational conditions that allow innovation to mature into competitive industrial activity.

A Broader Role for Port Authorities

Circular industry is built as much on rules, markets and finance as on technology. Four priorities follow:

• Complete the single market for secondary raw materials, with harmonised end-of-waste criteria that are mutually recognised across borders and enforced at customs, so that a recycled material is a product everywhere or nowhere.
• Create demand certainty through recycled-content mandates with clear accounting rules for chemical recycling, so that off-take can be bankable before plants are built.
• Align public finance with permitting timelines, combining EU, national and regional instruments so that first-of-a-kind projects can reach a final investment decision within a few years rather than a decade.
• Treat ports as system integrators. Zoning land for circular industry, providing shared utilities and pilot infrastructure, and offering one point of contact for permits and partners is a role that port authorities are uniquely placed to take, and one that Indian ports developing their own industrial hubs can adapt.

NextGen District is not an end in itself. It is one example of how a port authority can help translate circular ambition into industrial reality by creating the conditions in which innovation, investment and industrial cooperation reinforce one another.

NextGen District is not an end in itself. It is one example of how a port authority can help translate circular ambition into industrial reality by creating the conditions in which innovation, investment and industrial cooperation reinforce one another. Port authorities can play a pivotal role in accelerating the circular economy by bringing together infrastructure, industrial partnerships, regulatory coordination and finance to help innovative technologies reach commercial scale. The experience offers a model that other port-led industrial hubs, including those in India, can adapt to their own contexts. Sharing this experience between ports, including at Sagarmanthan, is part of the same task.
