Every year, over 2.2 billion tonnes of solid waste are generated worldwide, with up to 40% remaining untreated. This leads to severe contamination of soil, air, and water. Traditional methods like incineration and landfilling release massive amounts of greenhouse gases — about 173 million tonnes of CO₂-equivalent emissions in 2023 while offering poor energy recovery.
At the same time, heavy industries such as cement, steel, and chemicals produce more than 30% of global CO₂ emissions, and current hydrogen production adds another 830 million tonnes annually. The result is a mounting environmental crisis demanding cleaner, more efficient solutions.
Plasma is generally known as the fourth state of matter. It contains a significant portion of charged particles – ions and/or electrons by further energizing gases through heating. At these extreme conditions molecular dissociation breaks apart any complex organic molecules into their individual atoms. Inorganic matter is melted and will end in chemically inert and safe to handle slag that can be used as a construction material.
Methane cracking for clean hydrogen production.
Transforming various waste into valuable syngas and carbon black with CO2 reduction.
Re-equipment of industrial gas torches with plasma torches.
PlasmaSun uses a DC plasma system, which achieves higher energy efficiency compared to AC systems. The DC plasma system also provides higher plasma densities and better control of plasma temperatures than AC and high frequency systems.
The starting material is pyrolyzed at temperatures of over 3,000 K using the plasma torch. Pyrolysis, i.e. the thermal decomposition of the chemical components without oxidation, breaks down the complex organic molecules into their individual atoms through molecular dissociation. The only residues are hydrogen and solid carbon, which can be used as a valuable raw material in industry.

Tonnes of waste are dumped every day, releasing harmful greenhouse gases such as methane (CH₄) and CO₂. The currently prevailing measures and national commitments are not sufficient to achieve the 1.5°C target. Our goal is to break down mixed waste and produce Syngas (H₂ + CO) minimizing production of CO₂. Further Carbon Black is produced, binding carbon from being released into the atmosphere.
The CO2 emissions need to drop significantly in the following years. CO2 intensive industries are challenged to implement new technologies transforming the current processes relying heavily on the burning of fossil fuels.
One example is the kiln process, where high temperatures are usually achieved by burning natural gas. Thus, the CO2 from this burning process is released alongside any additional CO2 formed in the kiln process.
Nonstationary Kiln (Batch Kiln)
Nonstationary kilns have an increased flexibility concerning sinter temperature and firing curve compared to a stationary kiln. Further, they can be easily shut down. However, nonstationary kilns exhibit a lower energy efficiency, increasing operational costs.
Stationary Kiln
(Tunnel Kiln) Stationary kilns require a constant sinter temperature and cannot be easily shut down for a short time span. In general, these kilns exhibit a higher energy efficiency and thus lower costs during operation.
With PlasmaSun we turn environmental challenges into sustainable & economical opportunities.
