India: Villagers living near an ACC Cement plant in Orissa have accused the company of mismanaging its fly ash. According to the villagers living in Khaliapali, crops have been damaged by runoff fly ash created by a captive power plant at the nearby Bargarh cement plant. The resultant slurry has also spilled into the fields of the neighbouring villages of Banjibahali and Baragad.

Khaliapali villagers have accused ACC Cement of taking over 12 acres of land in the village and forcibly dumping fly ash on it despite protests. They said fly ash has become a nuisance in the village as it covers the houses and village water tank rendering water unfit for human use.

Additional District Magistrate Srinibas Kabi commented that the Regional Office of the Odisha State Pollution Control Board (OSPCB) had noted the villagers' concerns. However, OSPCB Regional Officer S S Mishra said they had not received any complaint from the Bargarh administration.

Coal ash seems to be in short supply in the Philippines. Lafarge Republic has signed a deal with a local energy producer to buy coal ash from a new 600MW coal plant.

Although the cost of the deal was not announced, the agreement will run from when the plant starts operation until 2019. This move follows a similar arrangement by Cemex Philippines in June 2012. In that instance Cemex agreed to purchase coal ash from the 200MW Kepco SPC Power Corp plant in Naga, Cebu for US$0.95/t.

Distinctively both arrangements were set up in conjunction with local government. For the Lafarge deal part of the agreement involved donating at least 10,000 bags of cement per month for use in various infrastructure projects of the province. Bataan governor Enrique Garcia put the value of the deal at US$1.19m/yr. For the Cemex deal the Cebu Provincial Government signed the agreement. In November 2009 Cebu Province and Kepco entered into an Ash Disposal Agreement, where Cebu Province was granted exclusive rights to the ash produced by the power plant.

Adding to the suspicion that the Philippines lacks sufficient coal ash, back in the autumn of 2011, the Cement Manufacturers' Association of the Philippines (CeMAP) asked the Department of Trade and Industry (DTI) to impose mandatory quality standards on raw materials, such as coal ash. This followed accusations by CeMAP that poor quality coal ash might be behind complaints from contractors working on infrastructure projects. In 2009 a DTI profile on the cement industry placed the demand for Portland cement at 73% and the demand for pozzolan cement at 27% of the total.

Cement sales in the Philippines have been steadily growing over the last decade. Lafarge Republic announced in August 2012 that it was increasing its capacity to just below 9Mt/yr in 2013. Around the same time CeMAP released data showing that sales were up 20% year-on-year for the first half of 2012. The local industry reported combined sales of 15.6Mt in 2011. Previous to this, Holcim Philippines announced the US$9.46m upgrade to a previously closed mill in Batangas.

Philippines: Lafarge Republic has signed a deal with the provincial government of Bataan and GNPower Mariveles Coal Plant to buy coal ash from the latter company's 600MW power plant.

Lafarge Republic, formerly Republic Cement, said the deal will start once the power plant begins producing coal ash. It will expire in November 2019. The company didn't provide financial details of the deal.

In a transaction announced in June 2012, Cemex Philippines said it will buy for around US$1 each ton of coal ash to be produced by the 200MW power plant of Korea Electric Power in the central province of Cebu.

India: One of the leading cement makers in India, Ambuja Cements Ltd., has announced that it has acquired a 60% equity stake in fly ash maker Dirk India Pvt Ltd for USD3.5m. Ambuja Cement said that after the transaction is completed, Dirk and its subsidiary Dirk Pozzocrete will become units of the company.

Fly ash, which is produced by burning coal, can be added to cement as a supplementary material, enabling reductions in both production cost and the amount of carbon dioxide produced from cement manufacture.

US/Colombia: Ceratech, Inc., a producer of alternative, non-OPC cementitious materials, has accepted another strategic equity investment, this time from Colombian cement powerhouse Cementos Argos. The Ceratech investment follows Argos' recent expansion of its US presence through a USD 760m purchase of Lafarge assets in the south east of the country. The strategic investment will help Argos meet its goal of building a competitive advantage based on sustainability and innovation.

Ceratech's manufacturing process produces technologically advanced, more durable, 'sustainable cements' comprising 95% waste fly ash generated by electric utilities. Its production does not generate any CO2 and the product is well-positioned for adoption by contractors, distributors and companies that are looking for new solutions that better conform to green building initiatives.

The two companies will cooperate to develop and distribute Ceratech's cement through Argos' established ready mix channels throughout the mid-Atlantic, southeastern and southwestern US markets.

"This strategic investment being made by Argos shows how important innovative, sustainable construction products are to the industry," stated Jon Hyman, CEO of Ceratech. "Ours is the only cement on the market composed of more than 90% fly ash. As the industry's only carbon-free cement, we exceed the requirements for green building practices such as USGBC's LEED rating system."
