The Cement Sustainability Initiative (CSI) has announced its aim to reduce CO₂ emissions by clinker producers by 20 - 25% by 2030. It made the announcement as part of a new action plan launched on 8 December 2015 at the 2015 Paris Climate Conference (COP21).

Most of the plan follows the CSI's existing aims announced to chime with the on-going COP21 negotiations. The plan depends on a long-term agreement being brokered successfully in Paris at COP21 as a whole. It then recommends policy in each of its key areas to achieve its goals. All of this sits beneath a general policy statement to, '...encourage policies for predictable, objective, level-playing and stable CO₂ constraints and incentives as well as energy frameworks on an international level.'

The Cement Action Plan is part of the World Business Council for Sustainable Development Low Carbon Technology Partnerships initiative (LCTPi). It puts together a series of measures to aspire to reduce CO₂ emissions by 1Gt by 2030 compared to business as usual. However this reduction is dependent on the entire cement industry getting involved, not just the existing 26 CSI members. Together these 26 members represent just a quarter of world cement production.

The drop in emissions is based on the so-called 'best-in-class' CSI company 2020 targets. To reach this the CSI is suggesting actions including focusing on recording Chinese cement industry emissions and energy usage, improving energy efficiency, promoting co-processing of alternative fuels, further lowering the clinker factor of cements, developing new low-energy and low-carbon cements, looking at the entire build chain to reduce emissions and considering other options such as carbon capture and storage. The plan had the support of the CEOs of 16 cement companies at its launch, with CNBM CEO Song Zhiping adding his assent at the event also.

The most prominent step is the clear focus on China for data capture using existing CSI tools such as the CO₂ and Energy Accounting and Reporting Standard for the Cement Industry, the Getting the Numbers Right (GNR) and the Cement Technology Roadmaps. As the CSI puts it, "What gets measured gets managed."

Given that China produces around 60% of the world's cement, according to United States Geological Survey data, the focus on China is essential. Currently the CSI has six Chinese members: CNBM, Sinoma, China Resources, Tianrui Group, West China Cement and Yati Group. Notable exceptions to CSI membership from the world's biggest cement producers include the Chinese producers Anhui Conch and Taiwan Cement, as well as Russia's Eurocement and India's Aditya Birla Group.

So, the CSI has set out its stall ahead of a hoped-for global agreement on climate change at the Paris conference. If some sort of legal agreement is reached then the CSI has its recommendations ready in the wings to hand to policymakers everywhere to promote its aims. If no agreement is reached then the plan loses momentum although pushing forwards makes sense where possible, starting with better CO₂ data reported especially in China.

Problems lie ahead for the CSI whatever happens in Paris given that the LCTPi Cement Action Plan is a series of policy suggestions from only 16 cement producers aiming for a non-binding target. For example, without some sort of world legal agreement there are clear commercial advantages for non-CSI members to burn cheap fossil fuels in their kilns and undercut their more environmentally pious rivals. The sustaining low cost of oil, dipping below US$40/barrel this week, can only aggravate this situation and distract the strategies of fuel buyers away from co-processing upgrades.

Colombia: The Cementos Argos board of directors has unanimously appointed Juan Esteban Calle as the new CEO of the company as of 1 April 2016. Calle will replace Jorge Mario Velasquez, who was recently named the new CEO of Grupo Argos.

Calle holds a bachelor's degree in business from EAFIT University (Medellin, Colombia) and has a master's degree in business administration (MBA) with emphasis in finance and economics from the University of Chicago.

Since January 2012, Calle has been the CEO of the Empresas Publicas de Medellin, a residential public utilities company with operations and subsidiaries across the Americas. Throughout his career he has held positions such as senior associate for Chase Manhattan Bank of New York (today JPMorgan Chase Bank), finance director for the Antioquia Department in Colombia, foreign investment director for Proexport in its Canada office, and investment advisor for the Bank of Montreal (today, BMO Financial Group), among others.

Calle is currently a member of the board of directors for Tigo-Une Comunicaciones, Empresas Varias de Medellin, Ticsa México and ENSA Panamá. He has also served on the board of directors for Isa, Isagen and Metro de Medellin, among others.

Iran: The National Iranian Gas Company has stopped supplying gas to a number of cement plants due to a wave of cold sweeping the country.

As gas consumption has peaked in the recent cold days, some cement plants, including those in the west of the country, have stopped receiving gas, according to Abdolreza Sheikhan, Secretary of Iran's Cement Association. He complained that with the shortage of gas, the plants cannot use the heavy fuel oil mazut either because a government law to provide the factories with mazut at the same price as gas has not been implemented. Despite the fact that the cement plants store enough mazut to run for 7 - 10 days, they are not using their reserves because they are not sure if they will receive mazut as the law has stipulated. Sheikhan said that, when the plants stopped working for 20 days under similar circumstances in 2014, the Oil Ministry refused to pay them from the income it had made by economising on gas.

Peru: Mexico's Mexichem has announced plans to acquire a Peruvian company in 2016 in order to participate in a new sector, diversifying its operations to achieve further growth. This will be Mexichem's fourth acquisition in Peru, as it has already purchased Plastisur, Interquimica and Comindustrias del Peru.

Mexichem's national operations are mainly focused on the infrastructure and construction sectors, in which it offers comprehensive solutions via its Plastisur and Pavco brands. Mexichem will also compete within the telecommunications and gas markets in 2016 and it plans to enter the cement industry with the company's existing product portfolio.

The aim in the cement sector is to import and sell fluorite. There is potential in the market as Peruvian companies use a different substance and fluorite can help to improve the mineralisation of cement, as well as reduce fusion temperatures. Mexichem is in talks with several local cement companies and progress is being made with respective tests for the use of this product.

Namibia: Ohorongo Cement Company has dismissed the construction of a US$343m plant by competitor Whale Rock Cement as a 'non-entity.'

Ohorongo Cement is, however, worried about the power generation challenges and drought. Marketing and Communications Manager at Ohorongo Cement, Carina Sowden, told local newspaper The Villager that new market players are the least of their fears. "Ohorongo Cement can already provide more than double the cement demand of the Namibian market. The question is raised as to why new investments are not rather focussed on the generation of electricity and energy, and the severe drought the country is currently facing," said Sowden.

"Competition is always a good thing, as long as the playing fields are level. The company has always had competition from both within the Southern African Customs Union (SACU) region as well as Angola and Zambia, where there is ample capacity," said Sowden.

In July 2015 Ohorongo Cement announced that it had invested another US$10.3m into a new composite cement plant, including new silo capacity and a packaging line. "Ohorongo Cement can now produce double the entire demand of Namibia and still absorb additional export volumes. All different types of packaging caters for both the local and export market, which includes 50kg bags, different sizes of big bags and bulk cement. Ohorongo Cement is able to produce various other types of consistent high-quality cement to differentiate itself from other cement manufacturers and more importantly, cater for the needs of its customers as well as for bigger projects. Some examples include the construction of the new container terminal in Walvis Bay, as well as the airport runway and wharf at St Helena Island," said Sowden. The new composite cement plant is expected to be completed by early 2016.

Sowden emphasised that as the Namibian economy is expected to see further growth, Ohorongo Cement has ensured in advance that it has the necessary production capacity to sustainably supply cement volumes for Namibia for the future. "This includes additional bigger projects that might materialise in future. The high-quality limestone deposits close to the Ohorongo Cement plant has been rated as the best available in Namibia and will last for more than 300 years," said Sowden.

Whale Rock Cement entered the Namibian market with its Cheetah Cement brand, which led to tough competition with existing cement suppliers, leading to a price war that drove it out of the market. Its new plant will be 245km from Windhoek and will be the second cement plant in Namibia after Ohorongo Cement, which produces 500,000t/yr.

Chile: Chile's environmental authorities have approved a plan of Cemento Polpaico for the construction of a 23.5MW photovoltaic (PV) park as part of the country's power grid.

The approval envisages the installation of 243,120 modules near Cemento Polpaico's Cerro Blanco plant in Tiltil, Chacabuco. The solar facility will require an initial investment of US$42m and its energy will be injected into the grid through the existing interconnection with the Punta Peuco substation. The annual output is estimated at 44GWh. The company will need around 112 workers during the construction phase, which could start at the end of April 2016, and up to 10 workers during operation.

Romania: Germany's HeidelbergCement has completed the merger of the three companies it owns in Romania. The three companies that are now merged under HeidelbergCement are Carpatcement, Carpat Beton and Carpat Agregate.

"The merger process takes into account our strategic position in relation to the economic environment, which is to overcome future challenges in order to use our resources to their full potential and to have a more efficient management of costs," said General Manager Florian Aldea.

HeidelbergCement is one of the leading manufacturers of cement, concrete and aggregates in Romania with three cement plants in Tasca, Chiscadaga and in Fieni. It also owns 19 concrete plants, seven quarries and six gravel aggregates units.

South Korea: A new solid recovered fuel (SRF) production facility is now fully operational in Wonju City, South Korea, thanks to global shredding company UNTHA and local partner PERITUS.

Korean waste management specialist Zion has built the SRF manufacturing plant to make smarter use of its residual materials. Now, with the new system in place, pre-sorted construction and demolition waste and commercial and industrial waste, is being shredded to produce a homogenous 50mm fuel for the cement industry.

The UNTHA XR3000C shredder with cutting concept was chosen following a series of trials at UNTHA's Austrian headquarters. Demonstrations showed that the technology could comfortably achieve throughputs of 60-70t/day, with scope to almost double that moving forward. The XR3000C's flexibility also means Zion can achieve a 40-50mm particle size from the single step shredding of plastic bales, which has further boosted the company's SRF production capabilities.

"South Korea may only be in the infancy of its waste-to-energy journey, yet the nation has formed a very sophisticated and disciplined approach to its waste roadmap relatively quickly. Legislation is in place to drive the production of <50mm SRF and the necessary infrastructure is fast evolving to accommodate this," said UNTHA's Head of Business Unit Waste Peter Streinik. "What we see here with Zion, however, is not just a company striving for compliance. They're prioritising energy efficiency, profitability and innovation too, to realise the wider benefits that come with smarter waste management."

Committed to principles akin to Europe's waste hierarchy, Zion extracts as many materials as possible, including bricks, metal, sands, glass and batteries, for re-use or recycling, prior to them entering the SRF manufacturing stream.

"Our family-run business is incredibly passionate about renewable energy, from solar power to alternative fuel production," said Zion's President Geumju Kim. "Now that our new SRF plant is up and running, with state-of-the-art configurable technology in place, the next step is to investigate relationships with different customers. We can satisfy varied specifications, and look forward to improving South Korea's resource agenda."

China: Shanshui Cement's major operating unit, Shandong Shanshui Cement Group, has said in a statement that the Shanshui Cement Board's removal of Management and Directors from Shandong Shanshui by Tianrui Group was illegal as it required government approval. Tianrui, the largest shareholder of Shanshui Cement, took control of the board at an extraordinary general meeting (EGM) on 1 December 2015, resulting in the removal of Shandong Shanshui management.
