A Strategic Alliance with Tangible Results

The collaboration between Cortizo, Spain’s leading aluminium and PVC systems producer, and residential developer Neinor Homes has reached a new milestone. Launched in 2023, their partnership has already prevented the emission of 4,280 tons of CO₂ in the construction of more than a thousand homes – equivalent to the annual emissions of 3,300 petrol-powered cars, according to calculations by the US Environmental Protection Agency.

Recycling at the Core

This achievement stems from the use of Cortizo’s Infinity billet, a raw material produced entirely from post-consumer aluminium. Windows, doors, façades, balustrades and other products are collected at the end of their life cycle, melted down and reintroduced into production. The process carries an Environmental Product Declaration confirming that every kilogram of Infinity aluminium generates just 0.92 kg of CO₂ – an 86% reduction compared with conventional billet. Energy consumption is cut by as much as 95%.

Industry Leaders Signal a Shift

For Cortizo, the agreement demonstrates how industrial partnerships can accelerate the decarbonisation of housing. “Establishing a strategic alliance like this with one of the leading real estate developers in our country represents a turning point in our commitment to sustainable construction,” said Daniel Lainz, General Manager for Architectural Systems. He added that Infinity has become “a crucial player in the decarbonisation of the Spanish housing stock” within just two years.

Neinor Homes also highlighted the impact. Lucas Galán, Director of Product and Innovation, said the results strengthen the developer’s leadership in efficient construction. For him, the partnership provides “measurable outcomes” while also setting “a realistic and replicable precedent” for more circular and environmentally responsible building.

Towards a Circular Future

The outcome underlines the potential of secondary aluminium to support Europe’s climate goals while meeting the growing demand for sustainable housing. As both companies stress, measurable CO₂ savings and replicable models are no longer aspirations but practical steps now being integrated into Spain’s residential sector.
