When Sustainability Becomes a Material Fact

Sustainability is often discussed as an ambition. Rarely does it become a measurable material reality. That is why the recognition of Hydro CIRCAL 100R at the Dezeen Awards 2025 matters. Awarded Sustainability Project of the Year and Material Innovation of the Year, it signals a clear shift for the building industry: circular aluminium is no longer a concept. It is proven, scalable, and ready for architecture. Read the full recognition on Dezeen

A Material That Changes the Rules

Hydro CIRCAL 100R is the first aluminium produced at industrial scale using 100 percent post-consumer scrap.

Not production offcuts. Not theoretical recyclability.

Real aluminium recovered at end of life, recycled back into high-performance material.

The result is a verified carbon footprint of around 0.5 kg of CO₂ per kilogram of aluminium, representing up to 97 percent lower emissions compared to the global average for primary aluminium.

The Dezeen sustainability jury described it as a breakthrough that demonstrates “infinite recyclability with no waste”.

That statement captures the shift. This is not about reducing impact at the margins. It is about redefining what aluminium can be.

Why This Matters for Architecture

For years, sustainability in construction came with trade-offs. Lower carbon often meant reduced performance, limited finishes, or restricted applications.

Hydro CIRCAL 100R proves the opposite.

It delivers the same mechanical strength, durability, surface quality and design freedom as primary aluminium. It can be extruded, anodised, coated and integrated into complex architectural systems without compromise.

From façades to windows and doors, performance remains unchanged. Only the carbon footprint is transformed.

That is why this recognition goes beyond a material award. It validates circular aluminium as a credible, future-ready building solution.

What It Means for TECHNAL Projects

At TECHNAL, sustainability is engineered into our systems, not added as an afterthought.

Our approach goes beyond material selection. It covers lifecycle thinking, circular design, responsible sourcing, energy efficiency and long-term performance across windows, doors and façade systems. Learn more about TECHNAL’s sustainability commitments

By integrating Hydro CIRCAL into our aluminium solutions, we enable architects, developers and homeowners to:

• Design high-performance façades, windows and doors with significantly reduced embodied carbon

• Meet evolving environmental regulations and green building requirements

• Specify materials with verified data, traceability and transparency

• Support true circular construction, where aluminium can be recycled again and again without loss of quality

This is sustainability that performs. Sustainability that scales. Sustainability that can be specified today.

From Recognition to Responsibility

Awards matter when they confirm direction.

The recognition of Hydro CIRCAL 100R by Dezeen confirms that low-carbon, circular aluminium is no longer experimental. It is ready to become mainstream.

For TECHNAL, this is both validation and responsibility. Validation that our commitment to circular materials is the right path. Responsibility to make these solutions accessible, credible and relevant for real projects across India and beyond.

Because the next generation of buildings will not be defined only by how they look or how they perform.

They will be defined by what they are made of.
