Slovakia: Technology provider A TEC, in collaboration with raw materials company Ferro Duo GmbH and Holcim's Rohožník plant in Slovakia, are now able to provide a complete solution for the recovery of bypass dust in the cement industry for various conditions.

In recent years, A TEC has engaged in technologies for the use of alternative fuels, chlorine bypasses and the re-use and recycling of bypass dust in cooperation with Holcim. Ferro Duo has specialised in the recovery and processing of cement and steel industry dusts and has developed a patented process for treatment and recycling of bypass dust.

Nigeria: Ashaka Cement plc has come out against the Nigerian government's plan to ban the production of 32.5 grade cement in Nigeria. The Chairman of Ashaka Cement, Alhaji Umaru Kwairanga, said that rather than ban 32.5 grade cement, it should be produced alongside 42.5 grade cement. This would not only provide consumers with the freedom of choice, but also assist in securing jobs that have already been created through the production of 32.5 grade cement.

There had been arguments that the use of the 32.5 grade cement in the construction sector was a major reason for the increase in building collapse, which resulted in the formation of a technical committee to review cement standardisation by the Standards Organisation of Nigeria (SON).

"Cement is not responsible for building collapses in Nigeria," said Kwairanga." So much research has already been done and we have seen that building collapse is more related to issues other than the cement itself. It's either from the professionals or consultants that are handling the building jobs, who have not followed the specifications."

Kwairanga added that Ashaka Cement has approved plans to expand its operation with a US$606m investment in cement production in Gombe. The amount would increase the cement production capacity of the company to 2.5Mt/yr. Barring any last minute change, the ground breaking ceremony for the project will be performed by the Nigerian president Goodluck Jonathan in early April 2014.

Kwairanga said, "We are taking our US$606m investment to the north-eastern state of Gombe. The total value of setting up the 2.5Mt/yr cement plant and a power plant is US$705m.

India: The selection for the post of chief executive of the Cement Corporation of India (CCI), which is run by the state of New Dehli, has triggered controversy with regards to the preparation of the list of candidates and the criteria for selection, which was allegedly changed to include some names at the last minute. The CBI has taken note of complaints and is expected to order a probe soon.

The Public Enterprises Selection Board (PESB) issued a list on 11 March 2014 with the names of 15 candidates who has been shortlisted for the interview. After about a week, the PESB released a list of 16 candidates, allegedly flouting its own guidelines on the upper limit on the number of candidates. In the second list an external candidate was added, with no explanation given. The candidate who was seventh on the first list was moved to number one position on the second list. The only internal candidate was allegedly downgraded to the second position on the second list after being put on top of the league on the first list.

Canada: Mantra Energy Alternatives has struck a deal with Lafarge Canada to deploy an electrochemical reduction technology at one of Lafarge cement plants. The technology will convert carbon dioxide emissions into useful chemicals.

"This will be the first pilot plant of its kind in the world," said Mantra's vice president Patrick Dodd. If the system works as advertised it could be deployed at all of Lafarge's facilities.

The technology would convert carbon dioxide into useful chemicals like formic acid and formate salts. The pilot plant would convert 100kg/day of carbon dioxide emitted from the cement plant into concentrated formate salts. Colin Oloman and Hui Li of the Clean Energy Research Centre developed the technology at the University of British Colombia. Mantra Venture Group then purchased it in 2008.

Mantra plans to use the formic acid for use in its patented fuel cells, which it bills as a significantly less expensive fuel cell with greater power density.

Now that the deal between Mantra and Lafarge has been signed, work will begin on the detailed engineering for the plant and the purchase of custom equipment.

Uzbekistan: OJSC Akhangarancement, a subsidiary of Russia's CJSC Eurocement Group, has received a limestone and marl production license for the Shavazsay field in the Almalyk region of Uzbekistan. A special commission of the Uzbekistan government issued the license, which covers the extraction of non-ore mineral resources.

The Shavazsay field, which was opened in 1974, has resources of 36.4Mt of limestone. Preliminary data shows that these resources will last for 25 years given Akhangarancement's current capacity.

Akhangarancement is one of the largest cement producers in Uzbekistan, with a 30% share of the market. It exports mainly to Kazakhstan, Kyrgyzstan and Turkmenistan. The company is projected to produce 1.99Mt of cement in 2014. Cement production increased by 6% in 2013, while clinker production increased by 13% in the same period. The company's mountain division produced 1.64Mt of limestone in 2013, up by 19% on 2012.
