Circular Online explores seven innovative ways that new artificial intelligence technologies are advancing the circular economy.

The shift from a linear economy where resources are extracted, used, and disposed of, to a circular economy where materials are kept in use for as long as possible is an essential part of tackling resource depletion and environmental impact.

While recycling remains important, circularity goes beyond simply managing waste – it focuses on prevention, reuse, refurbishment, and remanufacturing to design waste out of the system altogether.

Artificial intelligence (AI) is emerging as a key enabler of this shift. By improving material recovery, enhancing product design, and optimising supply chains, AI is helping businesses and policymakers make the circular economy more efficient and scalable.

Here are seven ways AI is already making an impact:

1. AI-powered sorting is improving recycling efficiency

One of the most immediate applications of AI in the circular economy is its role in waste sorting and recycling. Many recycling systems face challenges due to contamination, inefficient sorting, and an inability to process complex multi-material products.

AI is addressing these issues by increasing both the speed and accuracy of waste separation.

AI-driven computer vision technology allows machines to recognise different types of materials on a conveyor belt, distinguishing between plastics, metals, glass, and textiles with a high degree of precision.

Robotic arms, guided by machine learning, can then remove unwanted materials, improving the purity of recycled outputs. Over time, these AI models continuously learn and adapt, enabling them to identify new materials as packaging and product designs evolve.

Companies, such as ZenRobotics, TOMRA and Greyparrot, have developed AI-powered waste-sorting systems that significantly improve efficiency, ensuring that more materials are properly recovered and reintroduced into production cycles.

2. Machine learning is enabling smarter material design

AI is also transforming material science, enabling researchers to develop products that are easier to recycle, repair, and repurpose.

One of the biggest challenges in achieving circularity is the fact that many modern materials – particularly plastics and composites – are difficult to break down and reuse. AI-driven material discovery is helping scientists design more sustainable alternatives.

Machine learning algorithms can analyse the chemical properties of materials and predict how they will behave over time.

This can lead to the creation of self-healing polymers, biodegradable alternatives, and modular materials that can be disassembled and repurposed.

In the future, AI may even allow for programmable materials that can change their properties based on specific environmental conditions, making them more adaptable and reusable.

3. Predictive maintenance is extending product lifespans

One of the key principles of the circular economy is keeping products in use for as long as possible. AI is helping to achieve this by enabling predictive maintenance, which allows manufacturers, businesses, and consumers to anticipate wear and tear before it leads to product failure.

Rather than waiting for a machine or device to break down, AI can analyse performance data and detect early signs of deterioration.

This is particularly valuable in industries such as manufacturing, transport, and medical technology, where equipment failures can be costly and lead to unnecessary waste.

By predicting when maintenance is required, AI helps to extend the lifespan of products and reduce the need for frequent replacements.

Companies, such as Vanguard, are applying this approach in the medical sector, remanufacturing surgical tools to extend their use while maintaining strict safety standards.

4. AI is supporting circular product design

Circular economy principles are most effective when applied at the design stage. AI-powered design tools are helping businesses create products that are easier to repair, upgrade, and recycle.

By analysing vast datasets on material performance, supply chain logistics, and customer usage patterns, AI can assist designers in choosing the most circular materials and structures.

This approach is particularly relevant in industries like electronics and construction, where AI is being used to develop modular components that can be easily disassembled and repurposed.

Companies like Grafmarine are applying this concept in the energy sector, designing modular solar panels that can be repaired or upgraded rather than discarded when they reach the end of their initial use.

5. AI is enabling Product-as-a-Service models

The transition to a circular economy is not just about material recovery – it also involves rethinking ownership models.

AI is helping to support Product-as-a-Service (PaaS) models, where consumers access products through rental, leasing, or subscription rather than outright ownership. This approach ensures that products remain in circulation for longer, reducing unnecessary consumption and waste.

AI enables businesses to track usage patterns, optimise maintenance schedules, and predict when products need refurbishment or replacement. This makes PaaS models more viable and financially sustainable.

Companies, such as Grover, which rents out consumer electronics, and Rebike, which provides refurbished e-bikes, are already using AI to manage product lifecycles.

These models keep products in circulation for as long as possible, ensuring they are repaired, reused, and redistributed rather than discarded prematurely.

6. AI is enhancing supply chain transparency

One of the biggest challenges in achieving a truly circular economy is the lack of visibility across supply chains.

Many companies struggle to track where their materials come from, how they are used, and where they end up at the end of their lifecycle. AI is helping to close this gap by providing real-time insights into material flows.

Through the use of machine learning, big data analytics, and blockchain integration, AI can help businesses trace the origins of raw materials, monitor their environmental impact, and ensure that sustainability commitments are being met.

This level of transparency is particularly important in industries such as fashion and consumer goods, where supply chain complexity often makes it difficult to verify whether materials have been ethically and sustainably sourced.

AI-powered supply chain monitoring tools are already being used by companies seeking to improve their circularity credentials and meet evolving regulatory requirements.

7. AI is personalising consumer engagement in sustainability

Beyond industry and infrastructure, AI is also influencing how individuals engage with the circular economy.

AI-powered platforms are providing personalised sustainability recommendations, helping consumers make more informed choices about the products they buy, how they use them, and what they do at the end of their life.

By analysing purchasing habits and product usage patterns, AI-driven applications can suggest repair and refurbishment options, recommend second-hand alternatives, and connect users to local circular economy initiatives.

AI-powered chatbots and virtual assistants may also play a role in guiding consumers towards more circular consumption habits.

Looking to the future, AI could support systems where consumers are incentivised for sustainable behaviour, such as returning used products for refurbishment or opting for repair over replacement.

The future of AI and the circular economy

As AI continues to develop, its role in supporting circularity will only expand. From optimising waste management to enhancing material innovation, AI is already demonstrating its potential to make the circular economy more efficient and scalable.

However, its success will depend on collaboration across businesses, policymakers, and consumers. The integration of AI into circular economy initiatives needs to be guided by clear policies, ethical considerations, and investment in sustainable infrastructure.

If applied effectively, AI has the potential to accelerate the transition to a more resource-efficient, low-waste future, helping businesses and societies move beyond traditional linear models towards a truly circular economy.
