Aggneo® - Valorization of recycled aggregates from concrete waste in low-carbon concrete

Aggneo® recycles concrete waste by having dedicated platforms located near concrete plants and close to city centres (-2km). The process is a circular economy loop. An example is the LHB concrete plant in Lyon, transferring its waste to the Saint Fons platform, which recycles it into aggregates for the road and for concrete. The quality of the 4/16 materials is monitored. These materials are reintroduced into the concrete formulas of the concrete plants. These aggregates, stored in the open for a long time and with significant exposure, can further capture and sequestrate CO2.

Key features

  • Currently the 4/16 aggeo recycled gravel for concrete is introduced up to 150kg, which means as much as 250kg per cubic meter of natural aggregates saved
  • Reference building in downtown Lyon can include significant volume of concrete made with recycled aggregates, and obtain a better score within a sustainable construction labelling scheme
  • By 2025, LH forecasts to produce up to 70Kt in a single platform in France (allowing the storage of 900 tonnes CO2 per year)
  • The operation of one single platform can result in the saving of 100kt of natural raw materials
  • The integration of the solution into the urban areas provides answers to the issues of the construction sites located in the city, and the recovery of waste from deconstruction

Profitability

  • The development of cities such as Lyon is carried out by renovating and reconstructing low-carbon housing buildings on former industrial wastelands
  • LH intends to also treat and enhance non-inert, non-hazardous polluted soil, improving the efficient use of our natural reserves

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
  • Prototype testing 1:1 in the lab
