AI kiln packing at PSR

AI kiln packing to lower emissions

A new collaboration between Aberystwyth University and Parkinson-Spencer Refractories (PSR) in West Yorkshire will see the development of tools which use machine learning and artificial intelligence technologies to ensure a kiln is packed as densely and as efficiently as possible.

Currently, the average volume utilisation of a kiln firing at PSR’s factory is as little as 9%, due to the irregularity of the products being fired and the complex loading techniques. This limits the company’s manufacturing capacity and results in high energy costs and carbon emissions per tonne of product produced.

Any improvement in how kilns are packed during a single firing session would increase production capacity and energy efficiency, significantly reducing greenhouse gas emissions. To help find a solution, PSR has worked with Aberystwyth University on a successful application for a Knowledge Transfer Partnership (KTP) funded by Innovate UK and the Welsh Government.

A KTP Associate with a PhD and expertise in computational problem-solving has now been appointed. Dr Odin Moron-Garcia will take up his role in May 2025, working mainly at PSR’s factory in Halifax as well as collaborating with the research team at Aberystwyth.

The research team is led by Dr Adil Mughal from the Department of Mathematics at Aberystwyth University. He said: “This project plays a pivotal role in the exchange of expert knowledge and the bridging of the gap between academic research and industrial application.

“Creating innovative, customised algorithms to optimise the dense packing of complex-shaped objects will lead to a significant reduction in the ceramic industry’s carbon footprint, driving critical environmental benefits. These advancements will not only be a technical improvement to the manufacturing process but also a vital step towards sustainability in the industry.”

Simon Parkinson, the Managing Director of PSR, said: “We are delighted to be working with Aberystwyth University on this exciting and potentially transformative project. We hope it will lead to us being able to produce refractories in a more energy efficient manner, supporting our drive towards becoming a more sustainable business.”
