How Xella reduces CO2 emissions on a large scale

We prioritize sustainability by developing products and processes that use less CO2 emissions, eliminate waste and increase the reuse or recycling of products. We're also committed to providing a safe and inclusive workplace. Today's focus: our efforts to reduce our CO2e emissions.

The raw material autoclaved aerated concrete

Whether autoclaved aerated concrete (AAC) powder, which is recycled from production, or AAC from demolition projects, which is recycled according to type, is used in the production of new blocks makes no difference in principle.

Recycling without quality loss

What can be used in the recycled end-product and what cannot? The decisive factor for our quality standard in the use of post-demolition autoclaved aerated concrete (AAC) is the sorting accuracy.

Sorting is where it all comes down to

Xella's cooperation with Otto Dörner and Holcim shows how autoclaved aerated concrete residues are processed and reused in the manufacture of new products.

Close the circle: Recycling of autoclaved aerated concrete

Xella pursues three circulation models to return autoclaved aerated concrete (AAC) residues to the production cycle: This involves residues from production, from the construction site and even AAC residues from demolition and dismantling projects.

Cradle to Cradle: Recycling at Xella

For Xella, the circular economy is of enormous importance. The motivation for this are the legal framework conditions of the EU as well as the environmental aspect and the economic factor. The core of the circular economy is the Cradle to Cradle concept.

Economical and ecological: Ytong Big Bags benefit the Circular Economy

Ytong cellular concrete can be processed on site with comparatively little waste. As a rule, less than one percent of the delivered quantity is left over as cut waste, which was previously disposed of with the construction waste

Environmentally friendly and economical: recycling management in practice

Together with our partner company Otto Dörner, Xella Technologie- und Forschungsgesellschaft has started a project to reuse aerated concrete residues from mixed construction waste for the renewed production of aerated concrete.
