Transform your decomposed SF₆ into ultra-pure gas and make your infrastructure the protagonist of a true circular economy. Our cryogenic plant regenerates waste gas to a certified purity of >99.99%, drastically reducing the company’s environmental footprint and blocking the need to produce new gas.
The strategic necessity of SF₆ gas regeneration
The regulatory and environmental landscape is changing rapidly. Continuing to rely on virgin SF₆ represents a strategic risk today that no company can afford to take anymore.
The 2035 deadline: the end of virgin SF₆
Driven by the strict EU Regulation 2024/573, virgin SF₆ is already in a phase of progressive phase-out for new Medium Voltage (MV) applications. The final milestone is set for January 1st, 2035, the date on which the use of brand-new SF₆ for the maintenance of all existing electrical infrastructure will be officially banned. From that moment on, regenerated or recycled gas will become the only legal standard allowed to operate on networks.
The environmental imperative: beyond thermal destruction With a GWP (Global Warming Potential) of 24,300, SF₆ is the most potent greenhouse gas in the world. Regeneration represents the only responsible answer to break the obsolete and wasteful model of thermal destruction (incineration of waste gas). By regenerating already existing gas, the need to produce new quantities of virgin SF₆ is eliminated, ensuring that the same molecule is reused indefinitely. This process transforms a huge climate liability into a sustainable closed-loop asset.
Why choose regeneration: the triple advantage of our patented system
1.Economic Value: structural saving of 50% The traditional model forces companies to pay twice: to buy virgin gas and to dispose of waste gas. Regeneration breaks this costly cycle. Switching to our circular model reduces the overall gas management costs of your infrastructure by up to 50%, transforming a passive expenditure item into a high value-added resource.
2.Environmental Value: complete decoupling Choosing regeneration means completely zeroing out the carbon footprint and SF₆ emissions into the atmosphere associated with thermal destruction and the production of new gas. By purifying and reusing the exact same molecules indefinitely in a true closed loop, your company eliminates entire dependence on the newly synthesized SF₆ market and its end-of-life disposal.
3.Social Value: future-proof leadership Protect tomorrow by changing the way you operate today. Radically eliminating the production of greenhouse gases and the complex management of special waste from your workflow represents an ethical responsibility. This approach leaves a concrete environmental legacy for future generations, positioning your company as a leader in sustainable innovation.

SF₆ Regeneration: performance superior to virgin gas
In the industrial sector, a false myth is widespread: the idea that regenerated gas is a compromise, a “second choice” alternative to brand-new SF₆. Synecom’s proprietary process technology completely overturns this perspective. Through our advanced closed-loop industrial plant, we do not limit ourselves to simple recycling: we purify SF₆ gas reaching quality levels that actively exceed common virgin gas. While the standard new gas available on the market merely meets basic regulatory requirements, the Synecom regeneration process pushes chemical purity to the absolute physical limit. The result is a gas with such extreme and safe performance that it can be used even in the most sensitive and demanding high-tech industries in the world, guaranteeing absolute reliability and zero compromises.
Virgin SF₆ vs. Synecom Regenerated SF₆: The Direct Comparison
Meeting legal minimums is the standard. But today, the circular economy makes it possible to achieve superior performance with zero environmental impact. For the same application, Synecom’s regeneration technology offers an immediate purity upgrade compared to the equivalent virgin gas on the market.
| Application Field | The Standard (Virgin Gas) | The Upgrade (Synecom Regenerated) | Operational Advantage |
|---|---|---|---|
| Standard Electrical Grids | Virgin Gas 3.7N Purity: 99.97% | Synecom Regenerated 4.8N Purity: 99.998% | Asset longevity: Greater stability under electric arc, reduced wear, and zero carbon footprint |
| High-Tech & Medical | Premium Virgin Gas 4.5N Purity: 99.995% | Synecom Regenerated 5.2N Purity: 99.9992% | Zero defects: Maximum chemical safety at the nanometric scale for semiconductors and advanced diagnostics |
The Two Key Comparisons
Electrical Grids (3.7N vs. 4.8N): Although the 3.7N grade is regulatory compliant and sufficient, Regenerated 4.8N offers a significantly higher level of purity. It drastically reduces micro-impurities (air and moisture) that accelerate equipment degradation, providing a more stable grid while enhancing corporate ESG parameters.
Precision Technologies (4.5N vs. 5.2N): In high-tech industries, tolerance for contaminants is zero. While premium virgin gas stops at the 4.5N grade, Regenerated Ultra-Pure 5.2N guarantees the absence of foreign molecules, eliminating the risk of waste in microchip production and medical use.
The Proprietary Process
Thanks to a proprietary cryogenic distillation and multi-stage molecular filtration plant, Synecom eliminates every trace of contamination from the exhausted gas. The result is a ready-to-use resource with physical characteristics superior to those of newly synthesized gas.
Synecom & Terna: 57,000 kg of circular value
Our partnership with Terna is a true benchmark model for industrial circularity. Integrated directly into the Group’s 2024–2028 Sustainability Plan, Synecom’s proprietary technology is the engine of the “Closed-Loop SF₆ Management” project. With a clear and concrete roadmap, the goal is to regenerate up to 57,000 kg of SF₆ per year by 2028. In this way, we transform a critical gas from an environmental liability into a high-value resource, drastically reducing the ecological footprint of the National Transmission Grid and accelerating Italy’s energy transition towards a truly sustainable future.
