Brazil: FLSmidth has received two new orders in Brazil. The first is for a 3300t/day line for Pitimbu Plant, a greenfield project by Companhia De Cimento Da Paraíba in Paraíba state. The Danish cement plant supplier previously built a plant at Sete Lagoas for the client.

The second order is for an OK-33 vertical roller mill. Cimento Itambé has ordered the mill for cement grinding at its Balsa Nova Plant located in Paraná state. This is the 19th OK mill sold in Brazil.

"The awarding of these orders to FLSmidth is a consequence of a high market demand and has been given to FLSmidth in spite of great competitor interest in the same area," said President, Cement Division, Per Mejnert Kristensen.

Peru: Peruvian industrial conglomerate Grupo Gloria plans to invest US$217m towards upgrading production at its Yura cement plant near Arequipa. The plant currently has a cement production capacity of 3.5Mt/yr and the upgrade is expected to double production by 2016.

The project will include the installation of a new clinker line with a capacity of over 4500t/day, a new cement mill and bagging, pallet and loading equipment. The work will create more than 3000 direct jobs and over 9000 indirect ones.

Construction is set to start in 2013 with the mill complete by mid-2014 and the new clinker line ready by the end of 2016. Grupo Gloria is targeting the additional cement capacity at the south of Peru and Bolivia.

Switzerland: Global cement producers have reduced CO₂ emissions by 17% per tonne of cementitious product since 1990. Participating cement producers reduced their specific net CO₂ emissions per tonne of cementitious product to 629kg/t in 2011 from 756kg/t in 2011. The World Business Council for Sustainable Development (WBCSD)'s Cement Sustainability Initiative (CSI) has published the data in its 'Getting the Numbers Right' (GNR) database update for 2011.

"GNR has become established as a valuable source of independently-verified emissions data, which is now used globally by the cement industry to improve energy efficiency and further reduce emissions," said Philippe Fonta, WBCSD managing director. The WBCSD added that the GNR figures provide evidence of the gradual decoupling of emissions and cement output, which demonstrates the significant progress made by the cement industry.

According to the data, the four main drivers for the reduction in emissions have been investment in more efficient kiln technology, increasing use of alternative fuels such as biomass, reduction in clinker content and an 8% decrease in electricity use per tonne of cement since 1990.

The 2011 GNR data comprised 55% of cement production outside of China, with 96% coverage in Europe spanning 967 individual facilities. The 2011 report included data from Thailand, Morocco, Philippines and Egypt for the first time.

US: VHSC Cement has announced the commercial release of Pozzoslag 1.2, a cementitious material made using coal fly ash as a raw material. VHSC promotes its product as a partial replacement to Ordinary Portland Cement (OPC), offering early set times, greater long-term strength and enhanced concrete durability. Users are also able to reduce their chemical additive packages and lower the total amount of cementitious binder material.

"Pozzoslag 1.2 is created using a patented process that was introduced into commercial operations in November of 2012. This new product uses raw fly ash as a base material to produce a cementitious blend of material that meets grade 120 slag strengths based on ASTM 989 testing protocols. Using Pozzoslag in concrete allows very high durability at routine replacement factors in the 55-65% range," said Buddy Pike, president of VHSC Cement.

VHSC Cement developed Pozzoslag to overcome the early set time issues that have historically hindered the use of higher volumes of fly ash and slag in many cement applications. Currently this process is used to produce materials that are currently being used in ready mix concrete, highways, roads, building foundations and precast and concrete products.

Pozzoslag 1.2 from the Limestone facility in Texas meets ASTM C989 performance specifications as a Ground Granulated Blast Furnace Slag (GGBFS). These products meet Grade 120 slag requirements.

US: Holcim (US), the current owner-operator of the Hagerstown cement plant in Hagerstown, Maryland and St. Lawrence Cement, which previously owned the same facility, have agreed to pay a US$700,000 fine and improve emission controls at the facility to settle alleged air pollution violations, according to the US Environmental Protection Agency (EPA). The action against the Hagerstown plant is part of an on-going nationwide EPA effort to tighten pollution controls in the cement industry.

The proposed federal court consent decree requires Holcim to install 'advanced pollution controls' at the plant, Holcim also pledged to spend at least US$150,000 to replace outdated environmental protection equipment.

"It has been a long standing issue and now the company feels that it really is in its best interest to find a resolution," said Holcim spokeswoman Robin DeCarlo.

The Department of Justice filed suit on behalf of EPA in 2011 accusing Holcim and the plant's prior owner, St. Lawrence Cement, of violating the federal Clean Air Act from 2003 to 2007 by modifying the facility's cement kiln in a way that produced 'significant' increased emissions of SO₂.
