What is Gasplasma^®

Gasplasma^® is the world’s most efficient energy from waste technology:

• High net electrical efficiency
• 98% landfill diversion
• Negative carbon footprint
• Very low emissions
• Zero bottom ash
• Virtually no residues
• Combined heat and power
• Small physical footprint

It works using three clearly defined sections:

1. Materials Recycling Facility and Fuel Preparation Facility
2. Gasplasma^® technology
   • Fluid Bed Gasifier
   • Secondly, separate Plasma Converter
   • Gas cleaning equipment
3. Power Island

Heat is recovered from the Gasplasma^® process maximising the efficiency of the fuel.

Materials Recycling and Fuel Preparation Facility

150,000 tonnes of residual waste (Municipal Solid Waste) / commercial waste per year is accepted into our materials recycling and fuel preparation facility.

Recyclable materials (glass, metals and hard plastics) are recovered and then the non-recyclable materials are dried and shredded to create 90,000 tonnes of Refuse Derived Fuel (RDF).

The Core Gasplasma^® Technology

Fluid Bed Gasifier – first stage
The RDF is put into a fluid bed gasifier where it is efficiently transformed into a raw synthesis gas (syngas) that contains tars and chars. The bottom ash from the fluid bed gasifier is then transferred into the plasma converter.

Plasma Converter – second, separate stage
The raw syngas is passed from the fluid bed gasifier into a separate plasma converter which uses a plasma arc to crack the long chain hydrocarbons in the raw syngas.  A pure, hydrogen-rich syngas is created and all the bottom ash is vitrified into a product called Plasmarok^®.

Gas cleaning and condition
The pure syngas is then cooled, cleaned and conditioned in standard equipment before it is passed to the power island.

Power Island

Gas engines or turbines use the pure syngas to generate clean renewable power.
