Technologies

We supply innovative and robust engineering solutions which are relevant in recycling and resource recovery applications.  Our advanced systems, including Waste Tyres Pyrolysis Plants, Waste Oil Distillation Plants and Waste Plastic Pyrolysis Plants, are designed to provide efficient environmental solutions which are economically viable over long periods of time.

​

We have particular expertise in the mining sector where remote locations and the accompanying cost of logistics, present a challenge for the disposal of waste tyres, plastics and lubricating oils.  These waste feedstocks can be processed on-site to produce fuels which may be used in mine operations.

Waste Tyres Pyrolysis

Brief Process Explanation:

  • Waste tyres are prepared for the pyrolysis process.

  • Tyres are loaded using the Auto-Loader to the Pyrolysis Reactor.

  • The pyrolysis reaction is thermal decomposition in the absence of oxygen.

  • The waste tyres transition from solid through liquid to gas phase.

  • The gas is condensed and cooled back to form a liquid Tyre Pyrolysis Oil (TPO).

  • Carbon char and scrap steel are removed from reactor.​

 

Waste Tyres Pyrolysis Outputs:

  • Some TPO from previous batch is used as the initial fuel for the pyrolysis process.

  • Gas generated during the process then kicks in as a process fuel.

  • TPO is a suitable fuel for furnaces, incinerators, lime kilns or may be further processed at a distillation plant to produce a diesel fuel.

  • Steel can be baled and sold as scrap.

  • Char has similar energy value to mid-range coal and could potentially be used as a fuel in furnace-like applications.

  • There is minimal / zero process waste. 

Waste Oil Distillation

Brief Process Explanation:

  • Separation of the raw waste oil prior to distillation removes solids and reduces water content.

  • The distillation process generates hydrocarbon vapour in the absence of oxygen allowing the vapour to rise over the cracking catalyst.

  • The catalyst breaks long chain (heavy oil) carbon chains into shorter chain (diesel oil) lengths - precisely as in refinery cracking.

  • The vapour is then condensed to provide a raw or “Base Diesel”.

  • Base Diesel is further treated to remove moisture. 

  • A blending module introduces additives which improve quality.

​

Waste Oil Distillation Outputs:

  • Indicative yields of Base Diesel can range between 70% and 80% of the mass of oil that enters the process.

  • Waste oil will vary in type and composition, as well as the degree of moisture and contaminant levels, which may cause variations in the levels of fuel yield.

  • Base Diesel blended with RPS additives can in most cases be tailored to meet engine manufacturers specification.

  • Unblended Base Diesel can be used in kilns, furnaces, incinerators and where dirty or poor quality diesel is commonly used as fuel.

  • There is minimal process waste.
