Austria: Unitherm Cemcon has launched the MAS DT rotary kiln burner, a new product in its Mono Airduct System (MAS) product line. The new burner is already in operation at six cement plants in Austria, Germany and France.

The new design uses a more efficient primary air injection, resulting in higher effective momentum and optimised combustion. Placing the adjustable primary air openings directly at the burner tip leads to unobstructed injection of the air jets into the kiln. With minimum losses at the air nozzles, the entrainment of secondary air is improved by approximately 15%.

The new primary air system, with discs instead of flexible hoses, requires less space inside the primary air channel. Therefore, the burner is smaller in diameter and lighter in weight, which reduces investment costs. Unitherm Cemcon says that the cooling of the outer jacket tube with the MAS system (hose and disc design) is superior to that of other rotary kiln burners, as 100% of the primary air is used for cooling. With the new disc system, the cooling of the burner tip is improved even further. The producer added that all new MAS DT burners showed improved lifetime of the refractory lining at the burner. On average the refractory lifetime is extended by approximately 20%.

Mexico: Cemex Ventures has invested in Linkx, a company that offers software to optimise goods delivery. The company’s software solution allows control of deliveries and vehicles in real time, allowing for data-based decision-making and facilitating communication and information among all involved parties: shipper, carrier, and receiver.

“This investment is a clear example of our offer. Linkx came to us at a very early stage, and together, we worked on continuous improvements by reinforcing their minimum viable product and offering continuous feedback on our knowledge of industry and technology. After numerous optimisations, we have piloted this solution with several Cemex clients to achieve a very robust solution for the supply chain management challenge," said Gonzalo Galindo, chief executive officer (CEO) of Cemex Ventures.

Cemex Ventures is the corporate venture capital wing of Cemex that was launched in 2017. It invests in startups with potential in the construction industry and works with entrepreneurs, universities and other stakeholders.

Brazil: Data from the National Union of Cement Industry (SNIC) shows that cement sales rose slightly to 12.7Mt in the first quarter of 2019 compared to 12.6Mt in the same period in 2018. Regional sales fell slightly to 6Mt in the southeast of the country including the major markets of Minas Gerais, São Paulo and Rio de Janeiro. However, most of the other regions reported growth, particularly the centre-west. SNIC president Paulo Camillo Penna said that March 2019’s performance was better than expected and that it was forecasting growth of 3% in 2019.

Brazil: The National Union of Cement Industry (SNIC) and the Brazilian Portland Cement Association (ABCP) have launched a Cement Technology Roadmap to 2050. SNIC president Paulo Camillo Penna said that the document would help the local industry cut its carbon footprint in the medium and long term. The roadmap was developed with the International Energy Agency (IEA), the Cement Sustainability Initiative (CSI) of the World Business Council for Sustainable Development (WBCSD), the International Finance Corporation (IFC) of the World Bank and a group of academics led by José Goldemberg.

The roadmap intends to reduce specific CO2 emissions by over 30% to 375kg CO2/t of cement in 2050. Key actions to 2030 include strengthening national and international cooperation, promoting new cement standards, raising the clinker substitution rate, promoting the use of alternative fuels in compliance with the National Policy on Solid Waste (PNRS), sharing best practive in energy efficiency and promoting resaerch and development in new greenohuse has mitigation technologies.
