Advanced Plasma Power

Advanced Plasma Power Limited (APP) is the world leader in waste to energy and advanced fuels technology.  APP is revolutionising the way in which we treat waste sustainably by maximising the value from it as a source of materials and energy while minimising the impact of waste on the environment.

APP has developed the Gasplasma® process, a clean, modular and scalable advanced waste-to-energy and fuels technology which delivers high efficiencies whilst minimising visual and environmental impact.

APP’s Gasplasma® technology converts waste and/or the outputs from any waste gasification process efficiently and economically into two products:

  1. A clean, hydrogen-rich synthesis gas (syngas), which can be used to generate electricity directly in gas engines, turbines or fuel cells and can also be converted into substitute natural gas, hydrogen or liquid fuels
  2. An inert product (Plasmarok®) that has applications as a high value construction material


The technology is patented internationally.

Why Advanced Plasma Power (APP)?

The core Gasplasma® technology is a two-stage advanced conversion process, which combines two long standing and well proven technologies (gasification and plasma conversion) in a unique configuration. After the removal of valuable recyclates, the Gasplasma® process treats a wide range of non-recyclable feedstocks produced from residual municipal solid waste and commercial/industrial waste converting them all into two high value outputs (Syngas and Plasmarok®) each with multiple applications. Gasplasma® offers a genuinely game-changing solution for a zero waste future.

APP's sister company, Tetronics International, is the world leader in plasma technology and has a long and successful history deploying its patented plasma technology – a key component in APP’s Gasplasma® process.

As a group, we have five decades of experience in delivering plasma systems across four continents around the globe; many of them have been in operation in some of the most challenging industrial environments for over 20 years.

Why Gasplasma®?

The Gasplasma® process pushes the boundaries of waste-to-energy technology.  It outperforms other solutions, both in environmental terms and on electrical efficiency.  The innovative combination of two established technologies (gasification and plasma conversion) allows for the highly efficient production of a very clean syngas, the essential component for efficient energy generation through gas engines or turbines and for other downstream applications.

APP’s Gasplasma® technology offers numerous unique benefits over conventional thermal treatment technologies, which include:

  1. Maximum energy efficiency
  2. Maximum landfill diversion
  3. Low environmental and visual impact
  4. Local, low impact solution
  5. Rapid deployment
Why Gasplasma®?

Transforming Waste into Energy and Fuels

The Gasplasma® process produces energy and fuels from a wide range of waste streams including:

  1. Municipal Solid Waste (MSW)
  2. Refuse Derived Fuel (RDF) and Solid Recovered Fuel (SRF)
  3. Commercial Waste
  4. Wood Wastes and Biomass
  5. Mined Landfill
  6. Auto Shredder Residue (ASR)
  7. Hazardous and Special Wastes
Transforming Waste into Energy and Fuels

Energy from Municipal Solid Waste (MSW)

Municipal Solid Waste (MSW), which includes household waste, is the residual waste put into a black bin bag or wheelie bin. MSW contains a mixture of recyclable, organic, inorganic and biodegradable materials. We recover as many recyclable materials as possible before drying and shredding the remainder to make a Refuse Derived Fuel (RDF) for the process. Our energy from waste process, Gasplasma®, transforms the RDF into a clean hydrogen-rich synthesis gas (syngas).

Energy from Municipal Solid Waste (MSW)

Generating Energy from Refuse Derived Fuel (RDF) and Solid Recovered Fuel (SRF)

A full-scale Gasplasma® plant can make its own Refuse Derived Fuel (RDF) from MSW/Commercial Waste.  The waste is brought directly into a fuel preparation hall at the front of the building. Inside the fuel preparation hall there is industry standard equipment that can recover recyclable materials from the wastes such as glass, metals and hard plastics.

The remaining waste is then dried and shredded to make a (RDF) for the Gasplasma® energy-from-waste process. Clients who already produce RDF may not require a fuel preparation hall.  APP can design a plant without this facility, accepting the RDF directly from the client.

Secondary Recovered Fuel or Solid Recovered Fuel (SRF) is often confused with Refuse Derived Fuel because they are similar in nature.  However, SRF is produced to reach a clearly defined standard such as CEN/343 ANAS whereas RDF is not.

Transforming Commercial Waste into Energy

Commercial Waste is similar to Municipal Solid Waste (MSW) although it tends to have more biodegradable products. Commercial waste is defined as all wastes created by commercial businesses.  This can include, but is not necessarily limited to, solid or liquid wastes originating from offices, stores, markets, restaurants, shopping centres and other enterprises.

We receive Commercial waste into the Materials Recycling Facility (MRF) at the front end of the Gasplasma® energy-from-waste plant. Any recyclable materials are recovered and the remainder is dried and shredded to make Refuse Derived Fuel (RDF). The RDF is used as fuel in the Gasplasma® plant to generate clean, renewable power and heat.

Transforming Commercial Waste into Energy

Generating Energy from Wood Wastes and Biomass

Wood wastes include woods from forestry, railways (e.g. sleepers), telecoms (e.g. telephone poles), timber manufacturing processes and the construction industry. Many of these types of wood tend to be contaminated with chemicals and other materials.  This contamination can make the waste wood difficult to use in traditional biomass to energy processes and potentially hazardous to the environment.

Our Gasplasma® technology is able to efficiently transform the organic biomass into a pure, hydrogen-rich synthesis gas and safely destroys any harmful or hazardous inorganic chemicals. All inorganic materials are made inert and vitrified into an environmentally benign product called Plasmarok® which can be sold as an aggregate for construction, generating a revenue stream.

Mining Landfill to generate Energy from Waste

Mining landfill is an innovative practice, which is a paradigm shift in waste management, where landfills can be considered storage of feedstock for waste-to-energy plants such as Gasplasma®. The process works by:

  • Extracting buried waste
  • Recovering valuable recyclates: glass, metals, hard plastics
  • Returning land for alternative uses
  • Eliminating greenhouse gas emissions caused by decomposing wastes

Millions of tonnes of waste, going back many decades, are buried in landfill around the world.  This waste creates significant amounts of greenhouse gases, including methane, a potent greenhouse gas, which if it is not managed properly has serious consequences for climate change and can damage the regional eco-system. Gasplasma® energy-from-waste technology is ideal for landfill mining projects. The landfill to energy recovery process works by:

  1. Mining material from landfill
  2. Recycling glass, metals and hard plastics
  3. Creating a Refuse Derived Fuel (RDF) from the mined waste
  4. Producing a pure, hydrogen-rich synthesis gas using Gasplasma®
  5. Generating clean, renewable power and renewable heat

Generating Energy from Auto Shredder Residue (ASR)

End of life vehicle processing recovers valuable recyclates and removes all pollutants from automobiles for recovery. After this process, the remaining vehicle is shredded for further treatment into smaller parts called Auto Shredder Residue (ASR) sometimes referred to as Auto Shredder Fluff or Car Fluff. ASR contains a mixture of the different materials that make up the automobile, including metals, plastics, rubbers and textiles. This mixture of materials makes ASR a difficult waste to handle and potentially harmful to the environment. The Gasplasma® energy from waste process breaks down the ASR as follows:

  • Organic materials are transformed into a hydrogen-rich synthesis gas which is used to generate power
  • Inorganic materials are vitrified to become Plasmarok®, which is certified as a building product
  • Any remaining ferrous and non-ferrous metals are recovered
Generating Energy from Auto Shredder Residue (ASR)

Genereating Energy from Hazardous and Special Wastes

Gasplasma® uses a DC Plasma Converter to crack impurities from the raw syngas.  The intense heat and strong UV light produced by the Plasma Arc neutralises hazardous wastes, such as sludge and oils, creosote and other preservatives and chemicals.  Gasplasma® transforms the organic parts of the waste into a hydrogen-rich syngas that is used to generate clean, renewable power and renewable heat. The second stage Plasma Converter makes hazardous elements inert and all the inorganic materials are vitrified into an environmentally benign product called Plasmarok®.

Energy from Waste: Construction and Demolition waste

Advanced Plasma Power’s Gasplasma® technology is a two-stage thermal process, comprising gasification and plasma treatment, where conditions are controlled to maximise energy conversion from the largely organic fraction of the C&D waste to a clean synthesis gas (syngas).

The hydrogen-rich syngas possesses a high calorific value and has low levels of residual tars, heavy metals and acid gases and can used to generate significant quantities of power, or be used has a feedstock for liquid fuel or other chemical processes.

The ash residues associated with many thermal processes for treatment of C&D waste, are transformed within the Gasplasma® technology into an environmentally inert vitrified product called Plasmarok®. Plasmarok® can be employed in a range of applications, such as simple construction aggregate, thus enabling customers to extract additional value from their waste.

The patented Gasplasma® technology of Advanced Plasma Power is well proven for a range of C&D wastes.
