End of Life Tyres - Pyrmin's Business

Pyrolysis is a technology that has recently matured to being efficient and non-polluting and is a way of returning plastic and other organic materials back to their constituent compounds. However, because different materials react in different ways at different temperatures, a consistent feedstock is required for the pyrolysis reactor. Tyres are an ideal source of such a material since there is a whole industry devoted to the collection and management of tyres which can supply tyres to Pyrmin.

Sold into metal recycling industry for use in new steel production

Refuse Derived Fuel (RDF)

Textile recovered from car tyres can be used as a fuel to generate heat and electricity

Tyre Derived Oil (TDO)

Can be further refined to produce diesel and other fuels. Can be certified as a part renewable fuel

Carbon Char (CC)

Can be used as an RDF or further refined to recovered carbon black (rCB)


Gas produced and left over from fuelling the pyrolysis process can be used to fuel a gas engine to produce electricity or burnt for heat.

Pyrmin has two main steps to produce the outputs of denatured tyres:


The shredding, separating and crumbing processes physically break down the tyres into their constituent materials: rubber suitable for input to the pyrolysis reactor, steel and textiles


The pyrolysis process heats the rubber crumb without Oxygen (more correctly called thermolysis) being present to break the rubber down into a syngas from which the TDO can be condensed and residual solids produced: carbon black

Pyrmin is focused on the conversion of tyres into the products of pyrolysis. Further processing is possible to add value but Pyrmin is not aiming to do this initially
