The development of continuous Carbon Dioxide assisted devulcanisation


The ReMould project will conduct research into the development of a novel, scalable, industrial process for the continuous production of high quality re-processable rubber compound, derived from end of life vulcanised rubbers (e.g. EPDM, Nitrile and SBR). Projects within this programme are designed to develop materials technologies that will faciliatte the development of value added products and processes with reduced environmental and societal impacts.


The principal aims of the project are to:

Develop the devulcanised tyre rubber for the re treading of passenger and truck tyres

Improve provessibility to enable extruded rubber profile to be produced

Succesfully scale up the process via the acquisition of large-scale process equipment



PJH works with both phyto and non phyto materials to develop a product which can be commercialised. Below are a few past and present projects....

Adfimax aism to improve liquid food safety, by removing mycotoxins and replacing the current filter aid (kieselghur) which is a known human carcinogen. This dual onjective ensures that our technology will be suited to multi industrial application; however, our primary target markets are the wine and beer sectors. Both consume large quantities of kieselghur and have ongoing legal and commercial requirement to minimise toxin residues in their products.


At the heart of Adfimax is a new filter aid product developed in a precursor Framework 7 project: DEMYBE. The Adfimax filter aid is based on an innovative treatment process applied to specific, natural, vegetable fibres. This new treatment enhances the fibres ability to preferentially adsorb toxic contaminants from beverages whilst improving their ability to act as a filter aid. Originally aimed at mycotoxin reduction in beer & wine, the technology has also demonstrated the capacity to remove pesticide residues with an efficiency that surpasses alternative methods.





Bio sourced reinforcing fibres and mechanical improvement


The project aims to develop the next generation of wood and cellulose-reinforced composites-so- called "enhanced wood-plastic composites" or eWPCs - for compllex structural and multifunctional components. Material development will be accompanied by parallel process development to optimise the potential of the new composites. The newly developed materials and processes will be implemented in four different industrial sectors: automotive, construction, electronics and packaging.



Oak Alternatives


PJH has identified a new opportunity to selectively and economically extract and modify tannins for improved sustainability in wine production. PJH technique allows the production of tailored oak alternative blends, please get in touch if you would like to trial some of our French and American Oak blends.

A few past projects....



PJH has developed a novel supercritical fluid extraction technique that allows selected removal of land contaminants and detects the level of risk presented. This replaces traditional sampling measurement techniques that are more expensive and often require off site anlysis and generally identify unsafe levels once impacts have been realised

Artefact Preservation


PJH has identified a novel technology that will aid the preservation of culturally specific materials. Utilising PJH's expertise in supercritical fluids, material impregnation, development & analytical screening.


The process enables safe, high speed, high volume & lower cost preservation of culturally significant materials and whole archives of historical records. This novel technology is an attractive alternative to the current high cost, labor intensive and extended methods of preserving such materials.

Removal of Biofilms in Medical Devices


PJH has developed Supercritical Technology that when combined with an anti dopant will prevent the formation of Biofilms or microbial bacteria on a range of materials used for medical devices and implants. For more info, get in touch
