Embracing Sustainability in Rotational Moulding Matrix Polymers Approach to Material Innovation
Matrix Polymers has ramped up its R&D to develop sustainable materials, recognizing that sustainability is now a core industry imperative, not a luxury. In rotational moulding, factors contributing towards sustainability can be advanced by selecting materials that reduce cycle time and energy use, cutting virgin material consumption through downgauging, using bioderived materials to lower carbon footprints, lightweighting with foaming, and integrating recycled materials—addressing various environmental and social challenges along the way.
Rising Demand and Regulation Drive Recycled Content in Plastics Industry
Recycling has become a major focus in the plastics industry, with the UK’s 2022 plastic packaging tax charging £210.82 per tonne on packaging containing less than 30% recycled content. Originally targeting singleuse items, these requirements have expanded due to rising consumer and corporate demand for sustainability, now encompassing more durable goods and longer serving goods. Further, the European Parliament has proposed regulations requiring automotive products to include at least 25% recycled plastic, partially sourced from end-oflife vehicles, underscoring the industry’s shift toward recycled content in long-lasting applications.
Engineering Sustainable Solutions
The drive to use recycled materials, especially postconsumer recycled (PCR) options, is encouraging engineers to reduce reliance on virgin materials.
Rotational moulding is particularly suited for durable goods which can achieve and extend product life spans up to 20 years, this is a significant opportunity to increase value of recycled material through the Roto process.
However, challenges like thermal degradation, differences in polymer structure, material chemistry, and limited supply chain stability hinder exclusive reliance on PCR materials from other polymer process methods.
Although there are many successful schemes globally to use recycled rotationally moulded products, which have good material hetaeristic we cannot relay on this alone.
Matrix Polymers addresses these issues by engineering PCR-based materials specifically tailored to rotational moulding, advancing sustainable options for long-lasting applications.
Balancing Sustainability and Performance
A major challenge in using PCR materials for rotational moulding is achieving the right viscosity and thermal stability. Material characteristics essential for effective sintering can be challenging to achieve if the materials were not originally designed for the rotational moulding process.
In recent studies at Matrix Polymers we have identified, adding 30% PCR results in a 50% drop in impact strength. This highlights the need for continuous innovation to balance sustainability with performance.
As the industry evolves, Matrix Polymers remains committed to refining these solutions, ensuring that rotational moulding contributes to a sustainable future through thoughtful material choices and advanced manufacturing techniques.
Expanding the Potential of Recycled Materials –

The Value of Research
Queen’s University Belfast
Queen’s University Belfast has been at the forefront of research into Rotational Moulding for over 30 years, and it continues to work with the industry on a wide range of technological innovations. Sustainability has been at the heart of much of its work from the development of the groundbreaking ‘Rotolog’ device in the late 1980s through the latest efforts to automate and add intelligence to the process.
Research into polymer materials has included efforts to understand and control the basic melting and sintering process that is fundamental to making the rotational moulding process more sustainable.
Research in the world of rotational moulding is key to evolving the technology by increasing performance and reducing limits and bottlenecks. The role of Queen’s University Belfast is strategic in driving rotational technology towards increasing levels of quality.
Increasingly Automated Technology
Automation is already bringing transformational change to rotational moulding through several new automated moulding platforms. Amongst these is the ‘Robomould’ system developed by AMS Robotics in Belgium, where a robot arm provides multi-axial movement of an electrically heated tool. In terms of sustainability the use of automated movement and electrical heating provide a quantum leap in the levels of energy efficiency and control. Furthermore, the removal of the oven is providing an open environment for researchers to exploit for the first time.
The Qualities of Recycled Plastic
Rotational moulding has been seen as a potential route for capturing some forms of plastics waste due to the relatively large size and longevity of many of its products. However, controlling the loss of impact strength and product colour are significant challenges. Blending, layering and foaming have all been shown to give positive results. In addition, innovative work on architectural blocks has demonstrated that rotational moulding can be used to create recycled products that are tactile and aesthetically pleasing.
Sensors and Instrumentation
With an improving diversity of computer software, and the rising capacity of computer hardware, computer modelling is increasingly being used as a research tool in rotational moulding. Some of the latest advances are in thermal models to assist in the design of electrically heated tools, models to predict powder movement and part wall thickness distribution, and simulations of part shrinkage and warpage. Modelling is also being used extensively in the design, analysis and performance testing of mould tools and final products.
Hydrogen Liners
With increasing process control and efficiency, new high technology applications are emerging for rotational moulding. One of these is in the manufacture of polymer liners for type IV hydrogen storage vessels. Here the process offers significant advantages in its production flexibility and its ability to ensure encapsulation of the polymer with metal components such as bosses and tailstocks. It also provides the advantages of multishot moulding that can add internal gas barrier layers that are essential for longer term hydrogen storage.
Sustainable Materials
Recyclate adoption in rotational moulding, especially post consumer recyclate (PCR), poses significant challenges. Collaboration with Matrix Polymers aims to address some of these. This research extends towards natural fibres and challenges, improve performance and mechanical properties of recycled materials for rotational moulding. To date this project has focused heavily on blending of recycled materials, modification of recyclate and investigating thermal stability. Furthermore, novel biopolymers and natural fillers which has complimented industrial trials at CP Cases.
Recyclable Biopolymers
