FAQs

What is plasma?

Plasma is an ionised gas, and is often described as the fourth state of matter, i.e. when energy is added to a solid (first state) and it becomes a liquid (second state) with more added energy it becomes a gas (third state) and when further energy is added it becomes a plasma.  Examples of plasma are lightning, sparks coming from static electricity, fluorescent lights, arc welding and the aurora borealis (northern and southern (polar) lights). Because formation of the plasma arc does not involve the direct combustion of fossil fuels, it is considered a clean heat source. Due to its compact and controllable nature, it provides unique opportunities for industrial processing.

Why is plasma different from incineration?

Unlike incineration, plasma does not require a mixture of fuel and air to create heat, and so it produces much smaller exhaust gas volumes. In addition, plasma converts nearly all the raw material into useful inert products, which makes it an almost zero waste technology.

Is there a way to test my waste stream?

Yes, Tetronics’ trials facility, the most comprehensive in Europe, has a unique suite of highly flexible pilot scale furnaces for conducting plasma trials across a wide range of material processes.

How much does a plasma waste recovery plant cost?

The capital and operating cost depends on parameters such as the volume of waste material and the type of material to be processed. Please contact Tetronics with an overview of your requirements to find out the likely cost of your project.

Are Tetronics’ plasma waste recovery plants cost effective?

When compared with other ways of treating waste, Tetronics’ plasma waste recovery plants are definitely cost effective. The economics of any treatment process will depend on the type and amount of waste being treated and local conditions, but the ability of Tetronics plasma systems to recover value from waste materials will normally ensure good cost effectiveness.

Tetronics can work with you to develop the commercial model for an application helping to quickly indicate its commercial viability.

What is Plasmarok®?

Plasmarok® is a safe inert strong, environmentally stable product that is recovered from the Tetronics waste recovery process that can be re-used as a building aggregate in a range of building applications so completing the sustainability cycle.

Can Tetronics’ plasma waste recovery plants treat my type of waste?

To date, Tetronics has processed a huge range of materials; therefore, it is highly likely the answer is yes. Visit our solutions page to find out more, or please contact us for further guidance.

How many commercial systems have you supplied?

Our technology has been tried and tested over five decades and has been used globally in more than 90 plants across a wide and varied range of applications.

What is the minimum and maximum volume of material for a plasma waste recovery plants?

Tetronics does not have a catalogue of ‘standard’ size plants because we design each plant to meet the client’s specific requirements. This means we have enormous flexibility to adjust the throughput of a plant depending on the amount of material to be treated. Ultimately, if we feel the required plant size is too large for a single plasma furnace then multiple lines can also be provided.

Can I recover energy from a Tetronics’ plasma waste recovery plant?

This depends greatly on the type of process being used and the type of waste being treated (influenced by its calorific value), but Tetronics’ commitment to environmentally friendly technology and our customer’s value for money means we are always seeking ways to re‐use the energy from the process where possible.

How safe is plasma?

Safety is paramount in our equipment design and operation. Plasma is a powerful and intense source of both light and heat and therefore needs to be treated with respect. Indeed, it is these properties that make it a useful industrial tool. Based on years of experience of plasma technology in the laboratory and in the field, Tetronics’ engineers take great care to ensure the equipment complies with all relevant regulations and is safe to operate, through a mixture of design monitoring, regular inspection and testing and thorough training of operators.
