Energy Efficiency & Sustainable Interventions at SIGMA
Powering a cleaner, smarter future for glass manufacturing
A Greener Horizon for the Glass Industry
The glass manufacturing sector is entering a pivotal era. With energy costs rising and climate regulations tightening, companies are racing to rethink their energy strategies. At SIGMA, we’re not just adapting—we’re leading.
Our investments in renewable energy, intelligent controls, and electrification are transforming how we produce, what we consume, and how we impact the planet. And today, these aren’t just plans on paper—they’re real, operational, and already delivering results.
The Electric Furnace Is Live—and Leading
Just a few months ago, we reached a major milestone: the commissioning of our fully electric furnace at the Plovdiv facility. Designed to reach 1750°C without compromising performance, this project represents both a technological breakthrough and a bold environmental commitment.
Thanks to direct integration with our photovoltaic system, this furnace is now running entirely on clean energy—and the impact is significant:
- Over 200 tons of CO₂ emissions eliminated annually
- Improved firing precision, leading to higher dimensional accuracy and material consistency
- Energy synergy: clean solar energy now powers the very core of our refractory production
What once seemed like a risk has become a success story—and a new standard for sustainable manufacturing.
Smarter Systems, Cleaner Operations
Our journey toward sustainability doesn’t stop at electrification. At both our Locate Varesino and Plovdiv sites, we now generate nearly 1 million kWh of solar power per year—avoiding more than 480 tons of CO₂ emissions annually.
We’ve also modernized key systems across our facilities:
- The revamping of dryers and Furnace 7 introduced PLC-driven controls, inverter-regulated fans, and real-time process monitoring.
- A centralized compressed air system optimizes energy usage and ensures operational continuity.
- LED lighting with motion sensors minimizes unnecessary consumption.
- Infrared heating and condensing boilers enhance efficiency while improving working conditions.
Each upgrade is digitally connected, energy-efficient, and designed for both performance and environmental impact.
Why It Matters—for You
If your organization is working to reduce Scope 3 emissions or align procurement with sustainability goals, SIGMA can be part of that journey. Our products now carry a significantly lower embedded carbon footprint, without compromising quality, durability, or reliability.
And in a market where sustainability is often treated as an afterthought, we’ve proven that responsible innovation can deliver superior performance—not just greener credentials.
Leading by Example
We believe sustainability is more than a corporate goal—it’s a challenge to the industry. SIGMA has demonstrated that electrification, clean energy, and advanced process control can coexist with uncompromising product standards.
Our message is simple: you don’t have to choose between values and performance. At SIGMA, they come together by design.
“We didn’t wait for sustainability to become mandatory—we made it real. Our electric furnace is a statement of what’s possible when you combine innovation, responsibility, and the will to lead.”
