Optimising sustainable aluminium coffee cup production with advanced modelling

In the fast-paced world of coffee consumption, the production of coffee cups presents unique challenges, especially as the industry prioritises sustainability. The intricate deep drawing process needed to manufacture these cups becomes more complex when incorporating recycled materials while still adhering to strict food safety standards. Current production tools and methods, such as deep drawing ratios and tool configurations, require thorough evaluation and optimisation to ensure high quality and meet the growing demands of the market.

EcoCup, an innovative project led by FIP-AM@UT in partnership with AMCOR and Jansen Machine Management, aims to address these challenges. The project aims to improve the efficiency, sustainability, and overall quality of coffee cups made from aluminum.By applying advanced modelling techniques and conducting rigorous testing, EcoCup is set to transform the manufacturing process, making it more efficient and environmentally friendly.

The project’s objectives include the assessment of mechanical methods for material and interface characterisation, ensuring that production materials meet stringent quality standards. Additionally, EcoCup will develop detailed simulation models to optimise the coffee cup production process, enabling improvements in design and sustainability. The project will also investigate the effects of using thinner, recycled aluminium and specialised coatings, focusing on maintaining product integrity while advancing eco-friendly practices.

Through these efforts, EcoCup aims to set new standards in the industry, leading to the creation of more sustainable and high-quality coffee cups.

APPROACH

The project combines experimental material testing with advanced finite element modelling to simulate and analyse the deep drawing process. Recycled aluminium is characterised through tensile tests, and its anisotropic behaviour is captured using appropriate yield criteria in simulations. These data inform the development of accurate material models used in ABAQUS to evaluate various tool configurations, drawing ratios, and process parameters. This integrated, data-driven approach allows the project to optimise forming operations while ensuring structural integrity and efficiency. The result is a sustainable manufacturing solution that meets quality standards without compromising performance or manufacturability.

OUTCOME

The EcoCup project successfully demonstrated how advanced modelling and experimental testing can optimise aluminium capsule production using recycled materials for sustainable, high-quality outcomes. The findings provide insights into sustainable material usage, process optimisation, and defect prevention, offering a valuable foundation for greener, more efficient packaging manufacturing in industry.

Key results include:

• Finite element model accurately simulated the deep drawing of aluminium capsules
• Tensile tests effectively characterized the anisotropic mechanical behavior of recycled aluminium
• A digital tool pipeline was developed to analyse complex manufacturing processes, replacing heuristics
• Enabled seamless collaboration among stakeholders for sustainable manufacturing solutions

This project was made possible through the Regio Deal supported by the Province of Overijssel and the Dutch State.
