Milestone breakthrough | Holcim ECOCycle technology landed in the world's first fully recycled concrete building

The Recyg Recygénie housing project, built by Holcim and Seqens, a social housing provider, was officially opened

in Jeannevilliers, north of Paris, France. This simple affordable housing community is the first building in the world to be built with fully recycled concrete, which is a milestone achievement in the field of building recycling and sets a new benchmark for low-carbon sustainable buildings in the world. The core of this

project relies on Holcim ECOCycle recycling technology to realize the large-scale application of fully recycled concrete, save 6000 tons of raw materials, and achieve a leap-forward breakthrough in the recycling of building resources. The core highlight

of the

project is the world

's first fully recycled concrete residential building

, which has saved 6000 tons of raw materials. Practicing the core technology

of low-carbon development

, relying on Holcim ECOCycle technology to enable landing

based on urban pain points, exploring a new path

of recycling construction, the current global urbanization is advancing rapidly, and housing demand continues to grow. The pain points of construction waste accumulation and high carbon emissions are becoming increasingly prominent. How to balance the quality of human settlements and low-carbon development and achieve waste reduction and carbon reduction in the construction industry has become the core development issue of global infrastructure. In this context, Seqens is determined to build the world's first fully recycled concrete residential project and explore a replicable landing model for sustainable urban architecture.

With cutting-edge technology and proven recycling solutions, Holcim is Seqens' partner of choice. No Noémie Bernard, director of planning and architecture at Seqens, said: "Holcim is the only company in the industry to implement fully recycled building technology, and its exclusive solution makes the vision of large-scale building with fully recycled concrete a reality." The core innovation of

this project is derived from the world's first 100% recycled concrete developed by Hollyon Innovation Center. All that component of the concrete, such as cement, aggregate, water and the like, are proces and prepared from recycled materials. Through Holcim's core ECOCycle recycling technology platform, the project converts waste building demolition waste (CDM) into high-standard building raw materials, realizes closed-loop regeneration of construction waste, and bids farewell to the traditional landfill waste mode.

Holcim, in conjunction with the French Center for Architectural Science and Technology, has carried out long-term special monitoring to comprehensively verify the compliance, stability and durability of concrete. Finally, this innovative building material has been successfully applied to all the main structures of the project, such as foundation, wall and roof, which fully proves that ECOCycle has excellent performance, high cost performance and can be promoted on a large scale, providing a mature path for the low-carbon transformation of global buildings. The core path of building decarbonization is to

deepen the recycling strategy and build up the hard power

of sustainable development. As a global benchmark enterprise of recycling building materials, Holcim incorporated recycling building into its core strategy "NextGen Growth 2030", and continued to drive the green transformation of the industry with technological innovation.

1. Annual average recycling of materials exceeds 30 million tons, and annual recycling of building demolition waste reaches 10 million tons

. 2. 2030 strategic goal: annual recycling of building demolition waste exceeds 20 million tons. Accelerate the implementation

of the recycling city industry benchmark, define the implementation of the next generation recycling building Recyg Recygénie project, and strongly prove with real cases that large-scale and standardized recycling buildings can be fully implemented and popularized.

From technical fortification to real landing, Holcim relies on ECOCycle cycle technology to continuously reconstruct the building cycle ecology. In the future, Holcim will continue to cultivate low-carbon technology innovation, build more benchmarking projects with mature and large-scale recycling solutions, help the world build a green low-carbon recycling city system, and promote the decarbonization transformation and sustainable development of the industry.
