The three principles of Cradle to Cradle
The Cradle to Cradle design philosophy is based on three core principles that redefine sustainability and help guide us in developing closed-loop, regenerative systems and products.
The Cradle to Cradle Certified® Certification
Cradle to Cradle Certified® is a prestigious certification standard for products designed for the circular economy. It evaluates products in five areas: material health, material reutilisation, renewable energy, water stewardship, and social fairness. Products are rated for their commitment to sustainability and continuous improvement.
Circular by design: Our BluRoX technology
The journey to our latest innovation was made of countless small steps. It has led us to completely rethink the cooling and freezing technology. The result is BluRoX, our revolutionary vacuum perlite insulation, which follows the principles of a circular economy. Not only is the technology extremely energy efficient but has allowed us to build a freezer where all essential components can be reused.
BluRoX – our vacuum perlite technology innovation
BluRoX is significantly more efficient than traditional foam insulation. Instead of the conventional polyurethane foam (PU), BluRoX uses a much more effective form of cold insulation: a vacuum. Finely ground lava rock, so called perlite, stabilises the vacuumed components. This approach ensures the best possible energy efficiency due to the vacuum's insulating properties and perlite's low thermal conductivity.
At the end of the lifespan of a BluRoX freezer, the perlite can be removed and easily reused. Additionally, the insulation is not bonded to surrounding components, meaning the outer shell and inner container can also be easily processed and reused.
The FNXa 522i – The first Cradle to Cradle Certified® freezer
Liebherr has pioneered refrigeration innovation since 1954. The latest testament is our FNXa 522i freezer with patented BluRoX technology, born from volcanic rock and a bold idea: to rethink freezing technology from the ground up.
Efficiency, recyclability, and repairability are designed into the product from the outset, aligning with the principles of a circular economy. This is also evident in the cooling module in the base, which can be easily removed, allowing for quick maintenance. Additionally, each essential component can be separated and reused at the end of its lifecycle, thus minimising environmental impact.
Awarded with Crade to Cradle Certified® Bronze
The Liebherr FNXa 522i freezer has proudly earned the Cradle to Cradle Certified® certification in Bronze, a testament to our commitment to sustainability and innovative product design.
