France: Switzerland-based LafargeHolcim and Netherlands-based Witteveen + Bos have launched the 3D Printing Hackathon, an event in which engineering, architecture, and materials science students will compete to develop a new product leveraging 3D concrete printing technology to solve major problems in construction.

LafargeHolcim will supply concrete and provide technical mentorship to contestants. The company said that, while construction accounts for 40% of global carbon dioxide (CO₂) emissions, 1.6bn people are altogether without adequate housing. “Building more with less accelerates the speed of construction and reduces a building’s footprint. Leading the way in green building solutions, LafargeHolcim is actively deploying 3D printing towards addressing these challenges.” Research and development head Edelio Bermejo added, “We need to join forces to make this ground-breaking technology a reality. Join us on this exciting adventure!”

The group is offering a prize pool of Euro15,000 and operational support for full-scale implementation of the winning 3D printing solution.

Spain: HeidelbergCement subsidiary FYM has partnered with the University of Malaga (UMA) to create a chair on climate change at the institution. The position aims “to create and promote the study, research and development of new solutions to the climate emergency and its consequences for nature and daily life.” The company said that this consists in: “deepening the knowledge of the causes and consequences of climate change in Malaga Province, investigating the possibilities of its mitigation, especially through circular economic processes, encouraging research, development and innovation within the different lines of action in the fight against climate change, setting and substantiating industry targets and promoting understanding of the effects of climate change and the different forms of mitigation and adaptation.”

Pakistan: Cement producers dispatched a record 5.74Mt in October 2020. Exports rose by 12% to 875,000t from 784,000t. The Nation newspaper has reported that the figure brings Pakistan’s total dispatches for the first four months of the 2021 financial year, from 1 July 2020 to 31 October 2020, to 19.3Mt, up by 20% from 16.1Mt in the first four months of the 2020 financial year.

The All Pakistan Cement Manufacturers Association said that cement consumption may increase further if the government rationalises duties and taxes and withdraws excise duty.
