IRR Test Kiln Process

We are proud to unveil our material reprocessing facility, test kiln and research facility which allows customers to explore the possibilities of hard to recycle, and hard to treat waste streams.

IRR Test Kiln Process


What’s it all about?

The Pyrolysis plant at Worksop UK

End of life tyres is one of the hardest to recycle waste streams and our pyrolysis plant has shown that they can generate energy, oil and carbon char in a truly circular manner. So, if it works on tyres, what else can it work on? In the past, there has been lots of research done and suppositions made but now we are unveiling our test kiln as a research facility to gain greater understanding as to what can be processed in a hugely beneficial way. If you have a waste material that is hard to recycle, hard to treat, is costly to dispose of, or simply because you are driving forward the sustainability of your business, perhaps testing your waste in our kiln could unlock a whole new revenue stream for your business whilst responsibly managing your waste diverting it from landfill or ensuring it is processed responsibly in the UK.

How does it work?


Simply put we process the waste through our test kiln using a process called pyrolysis. Proven to be highly effective in generating by products and tackling material that is typically hard to recycle, the process is currently under-utilised as a means to dealing with waste. Our aim, together with our key partners is to research the waste streams in the UK and discover how effective they are when put through a pyrolysis process.

What is pyrolysis?


We think it is important to understand the process so here is the science bit.

Pyrolysis is a thermal process which takes place without oxygen. The absence, or near absence, of oxygen means that it is quite different to a combustion (burning) process. It can be applied to any organic (carbon-based) material and the process always produces a solid, a liquid, and a gas from the process which can be then used in further processes making it truly cyclical.

Through the thermal process, further products are formed that exhibit a different property and are typically highly beneficial and more valuable, in both financial and usefulness, than the original material.

How has the test kiln process been used before?

The test regime for the pilot plant is based around our knowledge of a variety of raw material and waste streams and their likely outcomes when heated in an oxygen free atmosphere. The prior knowledge is built up from past trials both by IRR Roslyn, and research in international experiments carried out by engineers, both in private and academic agencies.

The list of suitable products, that have been used previously, is by no means exhaustive, and is meant to heighten awareness as to other applications.

How is your waste tested?


We want you to understand the benefits of testing your waste and our process is entirely transparent. Upon receipt of your pre-agreed waste, we will process it through our pyrolysis test kiln at our headquarters in Worksop, Nottinghamshire.

We will provide a full analytical suite of information from the test process and this will give run data and back up information that can be utilised for future tests and valuable data for customers that wish to change the way they process waste and utilise our pyrolysis system on a long term basis. These will include:

Mass spectrometry
Gas chromatograph
Temperature flow through
Gas analysis
Residue analysis

This will enable investment and recycling decisions to be made going forward, determine added value revenue streams and help you to clearly understand how the process can re-establish key business processes with a sustainable and circular vision.

Which waste streams can our kiln process?


This is where it gets really exciting and why we are keen to offer our test facility to as many different types of waste producing streams as possible. This can be from a variety of sectors including manufacturing, NHS, warehousing, waste and recycling, hotels and restaurants, supermarkets, farming, and drinks manufacturers including UK vineyards, breweries, distillers and cider producers.

All have the same over-arching aim – to ascertain what can be processed through the pyrolysis process and how successful this can be.

Diverting waste from landfill (RDF and MSW) has also been successfully trialled and can reduce non-recyclable waste significantly and produce by-products for heat and energy generation.

Who can benefit from our test kiln process?


We’ve got an open mind and ask that you have too as there are so many waste materials that could be successfully processed. In partnership with Nottingham University, we are able to glean full understanding of each material and the benefits that using a pyrolysis process can bring in terms of processing that waste stream in a more responsible, sustainable and environmentally appealing way. Furthermore, there is the added value revenue streams that it may bring to your business.

Already we know that RDF, MSW, ELTs, plastic, wood and biomass material is successful through the process. Biomass would be plant or animal material that can either be purposely grown such as wood and forest management, or waste from horticulture, food processing, food crops and livestock farming. However, there are a diverse range of other materials that we are keen to understand.

Our test kiln is here to explore all those possibilities and provide you with the detailed information you require to highlight how investment in pyrolysis can bring environmental, recycling, energy and business benefits.

What does it cost?


As each process and test is bespoke, we ask that you give us a call or drop us an email so that we can discuss your individual requirements with you.

How do we make it happen?


Establishing lines of communication early on in the process is key so that we can determine the waste you have, what you hope to achieve and the long-term business strategy for commencing the test process.

We can then advise on the way we need to receive the waste, establish the financial element attributed to the process, and agree when the test will take place.

As this is our test kiln and research facility we are as interested in how material is processed as you, and look forward to exploring the detailed benefits of pyrolysis on a wide variety of waste streams.

What impact can it have on your business operations?


Exploring the opportunities through our pyrolysis plant will give you tangible data that can be utilised to develop a sustainable, carbon friendly recycling solution for the waste that your business generates. It will allow you to understand the quality of the by-products generated and how they can integrate into further energy generation, and what retail value the products may bring as an added value revenue stream.

Changing the way that your business manages its waste into an energy from waste (EfW) opportunity can significantly impact on business operations, both from a responsibility and financial aspect. In addition, it has the potential to set you apart from your competitors in a way that is truly aspirational and visionary and showcase to others in your industry an alternative way of dealing with hard to recycle or hard to treat waste streams.
