Switzerland: Dürr is supplying a regenerative thermal oxidation system (RTO) to Jura Cement Fabriken integrated plant in Wildegg as the main stage in its air pollution control system. The upgrade is intended to enable the cement producer to comply with anticipated lower gas emission limits for carbon monoxide, hydrocarbons, and ammonia (NH₃). The supplier says its solution combines Dürr’s Ecopure RTO multiple-chamber principle with an optimisation of the existing process technology in the calciner. It is scheduled to start operation in 2022.

Jura Cement operates two integrated plants in Switzerland. It is part of the Switzerland-based Jura Materials Group, which has been part of the Ireland-based CRH since 2000.

France: Vicat has joined US-based Schlumberger New Energy, clean energy specialist CEA, Vinci Construction and the Occitan Regional Agency of Energy and Climate (AREC) in a hydrogen production technology joint venture called Genvia. The partnership will establish a ‘gigafactory’ at which to develop high-temperature reversible solid oxide electrolyser technology. The gigafactory will be situated in Béziers, Occitan. Deployment will take place via CEA’s Grenoble, Auvergne-Rhône-Alpes site.

“We are very pleased to be working alongside such experienced and strong partners as we strive to develop technologies that enable decarbonisation,” said François Jacq, chairman of the CEA. “Together, building on a set of technologies developed by the CEA over the last decade, we have ambitious growth plans for a technology that we expect to be a game-changer in the production of clean hydrogen. This initiative demonstrates an alignment of environmental and economic growth ambitions that is important for France and Europe in support of the government's and the commission's recovery plan.”

The technology Genvia plans to use is intended to achieve a high system efficiency, resulting in less electricity use per kg of hydrogen produced. The venture says that the technology is the first of its kind that is fully reversible, giving it the flexibility to switch between electrolysis and fuel cell functions.

Spain: Cementos Molins has dismantled kilns 3, 4 and 5 of the Sant Vicenç dels Horts cement plant in Catalonia. The company says that it will use 48,000t of waste material from the demolition process in cement production in kiln 6 at the plant. The material consists of 35,000t of concrete, 10,000t of scrap metal, 1450t of refractory material and 1500t of other waste.

The total investment cost of the dismantling work was Euro2m. The company said that the demolition of silos presented the most complex challenges of the 24-month process.

The plant mothballed lines 3, 4 and 5 upon the opening of line 6 in 2010.

Switzerland: CemSuisse, the Swiss cement association, says that cement deliveries fell by 1.5% year-on-year to 4.15Mt in 2020. Deliveries remained stable in the first quarter before falling by 3.3% year-on-year in the second quarter at the same time of the first wave of the coronavirus pandemic. They subsequently recovered to a small increase in the third quarter before falling by 3.1% year-on-year in the fourth.

Argentina: Data from the Asociación de Fabricantes de Cemento Portland (AFCP) shows that cement shipments fell by 11.1% year-on-year to 9.87Mt in 2020 from 11.1Mt in 2019. They fell significantly in the first half of the year but subsequently recovered. Overall shipments - including local sales, imports and exports – last rose in 2017. Despite this, exports rose by 31% to 0.13Mt in 2020 from 0.10Mt in 2019.
