Ceramic industry should bring carbon reducing cold sintering process out of labs and into manufacturing says new research

A new techno-economic analysis, by a team led by a researcher from WMG at the University of Warwick, shows that the energy intensive ceramic industry would gain both financial and environmental benefits if it moved to free the cold sintering process from languishing in labs to actual use in manufacturing everything from high tech to domestic ceramics.

The new research has just been published in the Journal of the European Ceramic Society in a paper entitled “Decarbonising ceramic manufacturing: A techno-economic analysis of energy efficient sintering technologies in the functional materials sector”.

The cold sintering process (CSP) combines heat, pressure and the use of water to significantly reduce energy use as it lowers the temperatures required to produce ceramics to around 300 degrees centigrade. This is far less than other process such as: Conventional sintering, Laser sintering, Fast-firing sintering, Liquid-phase sintering, and Flash sintering which require far more energy and need to reach temperatures ranging from 1400 to 3000 degrees centigrade depending on the process and materials under consideration.

However the small scale of laboratory-based CSP (typically creating 5 grams of ceramic at a time under lab conditions) has meant that manufacturers have chosen to continue to rely on other significantly higher temperature methods that can either already produce larger amounts or can rapidly manufacture a series of small scale high tech ceramics. The University of Warwick led team believed that manufacturers had not developed anything like a full understanding of the potential financial and environmental benefits of using CSP in manufacturing – particularly as the start-up costs of CSP are much lower than other processes.

The researchers looked at scenarios for the processing of 3 separate functional oxides used to produce ceramics: ZnO, PZT and BaTiO3. They compared cold sintering (CSP) with a range of other sintering techniques and looked at its return on investment. They found that in all three cases, even after 15 years of use, the low set up costs of CSP made it the most economically attractive sintering option, with lower capital costs and best return on investment as well as considerable energy and emission savings.

The researchers do recognise that the transition from laboratory to industry of CSP will require hugely different facilities and instrumentation as well as relevant property/performance validation to realise its full potential but the potential benefits of doing so are significant .

Lead researcher on the paper Dr Taofeeq Ibn-Mohammed from WMG at the University of Warwick said:

“The rising cost of energy and concerns about the environmental impact of manufacturing processes have necessitated the need for more efficient and sustainable manufacturing. The ceramic industry is an energy intensive industrial sector and consequently the potential to improve energy efficiency is huge”

“Our research is the first comprehensive techno-economic analysis of a number of sintering techniques, comparing them with the recently developed cold sintering process (CSP). We find that there are clear financial and environmental benefits if the ceramics industry was to take the cold sintering process out of labs and into commercial manufacturing”.

We are investing in, and creating, several new world-leading facilities to support these new projects. So we also need to invest in more talented people to take these projects forward and we will intend to recruit 120 of those people in the next 100 days.”

Some of the most recent developments, at WMG include a new £13.5 million Energy Innovation Centre and the £150 million National Automotive Innovation Centre.


Strategic Partnership between WMG and Thermotec Plastics Leads to New Client Offering Worth £1.5 Million

ThermoteccBirmingham based Thermotec Plastics Ltd and WMG at the University of Warwick have worked on a project together to develop a new product offering for the automotive and aerospace markets that is worth £1.5 million in new turnover for the business.

Thermotec Plastics, an innovative and bespoke supplier of engineered solutions in vacuum forming and polyurethane mouldings created a new composite material with impressive lightweight properties and WMG undertook a testing programme that validated the product for market.

The collaboration developed when David Rose, managing director of Thermotec was asked for performance related data for the new composite material by a key automotive client. Thermotec was unable to produce the data in-house as the testing equipment required was investment prohibitive. He therefore approached WMG’s SME Team at the International Institute for Product and Service Innovation who were able to undertake the testing through their funded Innovation Programme for West Midlands SMEs.

New tech embeds mass customised hidden data in credit cards and plastics during manufacture

Gordon SmithBank card and other plastic product manufacturers will have access to a powerful new technology that will help the fight against counterfeiting of their products and which can provide an additional security feature for credit cards, thanks to new technology devised by researchers at WMG at the University of Warwick.

The technology will allow manufacturers to rapidly embed individual, unique and hidden individual pieces of data in each item made in large production runs of plastic products or credit cards as they are being created by injection moulding.

The researchers, led by WMG Professor Gordon Smith at the University of Warwick have just applied for patents to protect the new technology which uses the influence of a particular external force that exploits the polarity of particles and fluids, to very selectively influence those particles or a polymer fluid as a product is formed by injection moulding.
