Celsius from the Netherlands has successfully developed a specific technology using screw heat exchangers to carry out various pyrolysis processes. The process environment is inert and there is no combustion involved.

Due to the reduction in fossil fuel reserves and the demand for environmentally friendly production methods there is a great need for a sustainable and efficient recycling method.

‘Pyrolysis’ is an old Greek word and means ‘decomposition caused by heat’. In the Pyrolysis process materials are broken down into separate usable fractions. The material is as it were thermally decomposed, a process also called cracking or (incorrectly) dry distillation. It is essential for this process that no oxygen is present. The process environment is inert. There is therefore no 'combustion' involved. What remains, the end product, is a pure product.

The Pyrolysis process is a very environmentally friendly and safe method of processing organic material (waste). As a result there is a minimal emission of hazardous substances. The clean product obtained is suitable for recycling and even the Pyrolysis gas given off during the process is recycled in the plant as fuel. Screw heat exchangers have been used successfully in the pyrolysis process for processing biomass, car tyres, coal and Bioliq.

The concept was developed in the Test Centre of Celsius, headed by process technologist, Engineer Martijn van den Hil. Together with MSc. Manuel Paans, chemical technologist, they scaled up and developed the concept further. What once began as a pilot plant for carrying out and testing pyrolysis processes on a laboratory scale has now turned into large-scale long-term projects for a number of clients.
