LIEFPROD Project


This is a partnership comprising Sundeala Ltd, Building Research Establishment Ltd and AeroThermal Group to the Technology Strategy Board-funded LIEFPROD project (Low Environmental Impact Fibreboard Products).


The project, which started in May 2014 and will be completed in October 2015, will develop new wet-pressed fibreboard products to meet the requirements of a large segment of the UK board market, whilst incorporating waste and by-product material, which include end-of-life construction fibreboards and cellulose fibre derived from autoclaved municipal solid waste. The products will be based around a ‘closed loop’ board manufacturing process.


Board products are used in high volumes in the UK (e.g. as floor protection, sheathing and screening through to furniture). Existing board products are largely imported into the UK and are manufactured from wood fibre, often with the inclusion of synthetic adhesive binders. Difficulties in recovery, recycling and combustion mean that most waste board product ends up in landfill after a single use. 


The LEIFPROD project will build on a manufacturing process for fibreboard products from recycled and by-product materials to address design, commercial and materials’ processing barriers to the recycling of fibreboard products at end of (multiple) product lives.


The project will develop innovative commercial models (e.g. leasing) enabling the recycling/reuse of products at scale. It will also develop design approaches to enable incorporation of cellulose fibres from low quality sources such as treated municipal solid waste, enabling them to be incorporated into the board manufacturing process.

Scotland’s First 18-Foot Diameter Autoclave


AeroThermal in conjunction with AIC Group is designing and manufacturing a bespoke 18-foot diameter autoclave for UTC Aerospace Systems.  


The autoclave is the first of its size in Scotland and will enable UTC Aerospace Systems’ Scotland facility to maintain, repair and overhaul larger nacelles systems fitted to the next generation of wide-bodied aircraft.  


Work is already underway and the autoclave will be operational by the end of 2015.  It will be delivered to the site in two sections, due to its size, after being hydrostatically tested and re-welded together using a ‘golden seam’ which is 100% radiographic tested.

Case Studies

AeroThermal is a leading autoclave design and manufacturer for the aerospace, waste and industrial sectors.  We also offer high-quality laboratory services.


These case studies provide a taste of our capabilities and services.  However, it’s impossible to showcase all our projects so if you would like any further information, please simply contact us and we’ll be happy to chat through our work and your requirements in more detail.

Valorgas Project


AeroThermal has made a major contribution to a study examining the effectiveness of various pre-treatments to enhance the bio-methane yield from food waste.  Our contribution was to examine the effect of autoclaving on the digestibility of food waste.


The studies, which were partially funded by the EU, included small scale tests in Finland on material processed in our pilot scale autoclave in Poole, and larger scale tests over an extended period of time in a Biogen Greenfinch digester at Ludlow.


The latter tests required the regular autoclaving and transportation of substantial quantities of source-segregated food waste which was supplied to AeroThermal by Eco Sustainable Solutions from its base at Hurn.


These tests have shown consistent results and have concluded that autoclaving has a number of beneficial effects on food waste which is destined for use as a feedstock for anaerobic digestion.


The key benefits are:


• Lower ammonia concentrations

• Lower VFA concentrations

• Lower H2S concentrations

• Reduced pathogen levels

• High digester loading rates without the addition of trace elements

• Removing the requirement for shredding, sorting and pasteurisation


This project concluded that autoclaving, using the AeroThermal methodology, is particularly suitable for:


• Thermophilic digestion where trace element addition is less effective

• Feed stocks with high protein content

• Poorly sorted and contaminated feed stocks
