Artificial intelligence is revolutionising modern industry. Thanks to it, complex processes can be automated, efficiency increased and further innovations made possible. In the plastics industry, AI not only plays a decisive role in the optimisation of production processes and the development of new materials. It also enables more precise waste sorting and therefore better recycling – a win for the environment!
Digital transformation: A brief history of AI
Ideas about artificial intelligence date back to the early 20th century, when scientists began to consider the possibility of developing machines that could exhibit human-like intelligence. The modern era of AI began in the 1950s with the development of the first models, including Alan Turing's Turing test and Frank Rosenblatt's neural network. In the 1960s and 1970s, some successes were achieved in AI, including the development of expert systems. However, disappointments also followed when many early approaches failed to deliver the expected results.
In the 1980s, AI experienced a boom with the development of algorithms such as the backpropagation algorithm for neural networks and the support vector machine algorithm. Knowledge-based systems and expert systems became popular in the 1990s. These systems used rules and databases to make human-like decisions in specific domains. The algorithms make it possible to recognise patterns in large data sets and to model complex relationships.
From the 2000s onwards, AI experienced a further boom due to advances in machine learning and data analysis. Today, advanced AI technologies such as machine learning, image recognition and natural language processing are used in various areas of daily life. Companies are using AI to increase their efficiency, reduce costs, drive innovation and develop sustainable solutions, for example in the field of 3D printing.
Areas of application for AI in the plastics industry
Artificial intelligence has a wide range of applications in the plastics industry:
Process optimisation: AI can be used to optimise production processes and reduce energy consumption and waste. By analysing operating data and sensor data, algorithms can recognise patterns and make recommendations to improve efficiency.
Material development: AI can help in the development of new materials and compositions by applying simulation-based design methods and analysing large amounts of data to identify optimal material properties.
Quality control: AI can be used in quality assurance to detect defects or irregularities in plastic products by analysing images or sensor data. This can help to identify faulty products at an early stage and improve production quality.
Production planning and management: AI can be used in production planning and management to improve demand forecasting, optimise supply chains and manage stock levels. This helps to avoid bottlenecks and increase the efficiency of the entire production process.
Waste management: AI can help with the sorting and identification of plastic waste by using image recognition technologies and machine learning. This enables more efficient sorting and recycling of plastics, which helps to promote the Circular Economy.
- The start-up PolyPerception wants to revolutionise waste sorting with advanced AI models.
- In the KIOptiPack innovation lab, AI supports the design of sustainable packaging.
- EREMA shows how AI can increase the recycling rate of plastic.
- Thanks to AI technologies from STEINERT, plastic waste sorting at RE Plano is becoming more reliable and efficient.
- This is how machine manufacturer KraussMaffei utilises the potential of AI.
The contribution of artificial intelligence to sustainability
Artificial intelligence can support the promotion of the Circular Economy in various ways:
Recycling optimisation: AI can make the recycling process more efficient, for example by controlling robots in recycling plants to sort and process plastics more effectively.
Material identification: With the help of AI, plastics can be precisely identified, making it easier to sort recyclable materials and improving the quality of the recycling process.
Design optimisation: With the help of AI, plastic products can be designed in such a way that they are easier to recycle or can be made from recycled materials. This helps to reduce waste and promote a closed Circular Economy.
Sustainable production processes: AI can be used in production facilities to minimise energy consumption and material waste by optimising processes and using resources more efficiently.
Forecasting and analysis: By analysing large amounts of data, AI can help identify patterns in the consumption of plastics, predict trends and make informed decisions to reduce the use of plastics and promote the Circular Economy.

Challenges associated with AI in the plastics industry include data quality and quantity, as precise predictions and optimisations require extensive and high-quality data sets. Data privacy and security are also important to protect sensitive information. In addition, the integration of AI technologies into existing systems requires significant customisation and investment.
Another obstacle is the lack of skilled labour with the necessary knowledge of AI and plastics technology. Finally, employee acceptance poses a challenge, as the use of AI changes work processes. Employees may first need to be trained in the use of AI technologies.
AI in the plastics industry: an outlook
Overall, the future of AI in the plastics industry looks promising. There is great potential to significantly increase efficiency and sustainability. AI is expected to continue to optimise processes, from material selection to end-of-life processing, and promote innovative recycling methods. The development of smarter, self-learning systems could improve the adaptability of production and contribute to the realisation of a fully circular economy. Despite challenges in terms of data, integration and skilled labour, the increasing focus on sustainability and technological advances is expected to drive the adoption and implementation of AI in the industry.
BASF, for example, is working with other partners to show what this could look like using the example of mechanical recycling. Here, state-of-the-art measuring techniques are combined with AI. The approach seems very promising. Find out more in this news!
