InterCement, holding of the cement business of Group Camargo Correa, will invest R$ 2.5 million over the next three years in the development of a debris-based cement technology. The study will be conducted by the Institute for Technological Research (IPT) of São Paulo, and the funds will be used to pay for salaries, laboratories and equipment.
The Brazilian National Development Bank (BNDES) will also grant the same amount of a non-refundable investment totaling R$ 5 million. IPT’s research seeks to identify the process for large-scale production. A few studies previously conducted on the subject have been inconclusive.
Cement from construction demolition debris (RCD, in the local acronym) is a novel technology that provides a low-cost and environmentally-friendly material, since no further CO2 emissions are caused, unlike in the manufacturing of the conventional cement. “InterCement endeavors to provide the best service to its customers, differentiating itself in the market by presenting innovative products and services”, says Adriano Augusto Nunes, Sustainability and Innovation Director.
RCD cement’s destination is also different. It may be used to coat hard floors and refill ditches opened for water pipes, sewage channels and telephone lines, for example. When launched in scale, the product will reduce the use of natural resources by replacing natural aggregates such as sand and gravel, and also reuse the material that would be sent to landfills from construction sites.
InterCement will be responsible for launching the product on the market if its feasibility for large-scale production is confirmed. InterCement is among the 20 largest cement and aggregate producers in the world, and has 39 cement factories in South America, Europe, and Africa.
