A new innovation in “waste-to-electricity”: We have developed a three-stage gasification know-how that produces tar-free, NOx-free and hydrogen-rich synthesis gas from municipal waste and tires. We design and build power plants in many countries around the world. The power plant's energy source is the synthesis gas from waste gasification. Our gasification technology not only reduces waste, but also paves the way for clean energy production. In the molecular recycling of organic waste, we see a storehouse of carbon, hydrogen and oxygen atoms – the same atoms that make up our fuels, products and built environment, e.g. methanol synthesis, energy storage in liquid hydrogen at ambient temperature and atmospheric pressure. The three-stage gasification heart of the technology is the gravity coal bed, a self-regulating reactor in which the following takes place: a) The hot syngas that flows out pyrolyzes the fresh feedstock b) Activated carbon is produced, the syngas is filtered through this bed c) The tar is already bound and degraded in this stage d) The tarry coal is gasified in the lower stage. Microwave steam plasma – Complete tar degradation - The plasma zone is directly integrated into the carbonization/filtration stage. - It generates temperatures between 1200°C and 1800°C. - It produces radicals that completely degrade the tar and heavy hydrocarbons. - The plasma here is not a separate reactor, but part of the filter carbonization zone, which is completely different from current plasma tar reformers. Properties of the resulting synthesis gas - Completely tar-free - Completely NOx-free - Hydrogen-rich >60% e.g. for methanol synthesis - Reduced CO2 content - Ideal for gas engines, gas turbines. - Stable and predictable composition Four main pillars of tar-free gasification in the system: 1. Hot coal bed pre-phase. Hot synthesis gas + steam → carbonization + tar decomposition + gas quality improvement before downward extraction. 2. Oxygen-free, reductive medium. No air, no classic combustion, only thermally controlled pyrolysis/gasification. 3. High-temperature zones. Locally up to 1200°C, but the bed average can be kept around 700–900°C → good tar decomposition, still acceptable carbon yield. 4. The coal bed as an active tar reactor It not only filters, but also works chemically: thermal cracking, steam reforming, adsorption. Competitive advantages of the technology: 1) Low investment cost (CAPEX) - no fluidization, - no catalyst bed, - no separate tar treatment unit, - no complicated air distribution, - the filter regenerates itself. The project offers a unique opportunity to create a scalable, commercially viable waste utilization platform that uses jointly developed Hungarian-European technology, ensures energy security, circular economy benefits and investment attractiveness.
