France: Lafarge has announced that it has completed a industrial-scale trial to make Aether®, its new generation clinker formulated for lower carbon cements and has 25-30% lower CO2 emissions than normal clinker.
 


The trial mobilised a team of around 100 people over a 10-day period at the group's plant in Le Teil, France. It allowed the production of 10,000t of Aether clinker and, according to a Lafarge press release, confirmed the feasibility of industrial-scale production using traditional raw materials. 



The result of several years of research by Lafarge's research and development teams, the new clinker offers similar properties to OPC and can be produced in traditional cement plants after minor process adjustments. However, it has a lower overall environmental footprint, which is derived from having a lower limestone content in the raw mix, a kiln temperature in the region of 1300°C and lower-energy grinding.


Following sustained CO2 emission reductions since the early 1990s, Lafarge says that the Aether project will help it to reduce CO2 emissions per tonne of cement by 33% by 2020, one of its Sustainability Ambitions 2020 targets.

The first Aether products will be launched in 2014.

Brazil: The French building materials giant Lafarge has announced a US$500m investment plan in Brazil. On 11 January 2013 Bruno Lafont, group CEO, announced the five year investment in a civil construction research centre in the country at a meeting with the Brazilian President Dilma Rousseff. The move follows a number of asset sales by the group.

The Brazilian research centre will be the group's fifth outside France. The others are in the Netherlands, China, Algeria and India. In the past five years Lafarge has invested US$1bn in Brazil.

Italy: Italcementi has inaugurated its new research centre, i.lab, costing Euro40m near Bergamo in northern Italy. Once complete the centre, which was designed by US architect Richard Meier, will cover 23,000km³ and will employ 1300 researchers.

Italcementi will focus the research on the development of new building materials and on the use of renewable and reusable raw materials. The centre will also research special products such as 'pollution' cement.

In 2010, Italcementi's ITCLab received the European Greenbuilding Award of the European Commission for energy efficient construction and now the centre can also boast Leadership in Energy and Environmental Design platinum certification. The centre allows energy saving of up to 60% compared to traditional buildings, director general Giovanni Ferrari said.
