Building Materials
Advancing next-generation building materials by supporting impact-driven innovators with market-proven solutions, helping them scale globally through strategic guidance, market development, and access to financing.
Neo-Eco has been pioneering solutions to the world’s waste problem since 2008, using unique methodologies to turn waste into re-usable materials that are re-injected back into local economies. Their expertise covers circular economy engineering, full waste processing lines, their valorization, and the development of eco-products including low-carbon, circular concrete using mature-technology that replaces Portland cement with other supplementary cementitious materials (SCMs) to deliver low carbon concrete at scale while reducing CO2 by 90%.

Reducing Costs and CO2 Emissions for the Grand Paris Express’s 200km of New Metro Lines
As part of the Grand Paris Express project to add 200 km of new metro lines, a circular economy strategy was implemented to reduce costs, waste, and CO₂ emissions from millions of tons of excavated soil and demolition materials. By analyzing waste streams, conducting site visits, and developing eco-materials—particularly from the project’s 45 million tons of excavated earth—materials were reintegrated into construction, including low-carbon cement and reused building components through intelligent deconstruction. The initiative engaged public and private stakeholders, supported industrial-scale rollout, saved developers hundreds of thousands of euros, generated over 80 reusable eco-materials, mobilized more than 100 local construction companies, and significantly reduced landfill use while setting a new sustainability benchmark for large-scale infrastructure projects.
Eco-Friendly Conversion of a Private Parisian Mansion Into Office Space with AEW and Theop
The renovation of an 18th-century Parisian mansion into 2,500 m² of office space for AEW, led by Theop, applied a strong circular economy approach to minimize environmental impact while preserving heritage elements. By prioritizing on-site preservation, organizing careful ex-situ reuse of removed components, and sourcing reused or recycled materials through circular procurement, the project integrated sustainability into every phase of rehabilitation. Local reuse stakeholders and suppliers were engaged, environmental impacts were assessed, circular economy requirements were embedded into tender documents, and implementation was monitored throughout construction—ultimately supporting the project in achieving Level 3 of the Circolab certification.
Deconstruction and Reconstruction of RATP’s Saint-Fargeau Train Maintenance Workshop in Paris
The Saint-Fargeau Train Maintenance Workshop in Paris is being fully deconstructed and reconstructed to support RATP’s new MF19 metro trains, as part of a long-term modernization program running from 2025 to 2035. Since 2023, Neo-Eco has supported RATP Infrastructures as Circular Economy Project Manager, integrating reuse, recycling, and environmental performance into every phase of the project—from material diagnostics and early design through demolition, reconstruction, and contractor procurement. As one of four demonstrator projects under RATP’s Circular Economy Roadmap, the initiative embeds circular principles into technical specifications, construction oversight, and final performance evaluation, setting a model for sustainable modernization of major transport infrastructure.
Turkey’s Post-Earthquake Reconstruction
Following the devastating February 2023 earthquakes in southern Türkiye, a comprehensive circular reconstruction initiative was launched to address massive destruction across provinces such as Hatay and Malatya. The effort combines detailed damage and debris assessments with advanced eco-material engineering to transform earthquake rubble into high-value construction materials, significantly increasing the economic and environmental value of recycling for local rebuilding. Alongside the design of scalable debris recycling platforms, the project has mobilized international funding and worked closely with public and private stakeholders to overcome regulatory and cultural barriers to using recycled materials—laying the groundwork for a more sustainable, resilient post-disaster reconstruction process.
