The oleochemical industry offers products based on renewable feedstocks like natural oils and fats and, therefore, is one of the oldest industries of the European bioeconomy.
Claus Weyhofen explains how Beumer Group’s determination to reduce backfall in lifting operations led them to reassess and optimise the design of the elevator bucket, resulting in a far more efficient machine that delivers major benefits for the global cement industry.
This article explores the current state of decarbonization in the global cement sector, including innovative strategies, challenges, and the differing approaches between the Global North and Global South.
The topic of sustainability is not only a key issue in the cement, lime and gypsum industries, but is also of immense importance to publishers - including Bauverlag. At the company’s internal B.connect event on 22.08.2024, Bauverlag Managing Partner Michael Voss gave a keynote speech on the “great challenge of our time”.
Once a year, ZKG CEMENT LIME GYPSUM is published with a green logo. Once a year, ZKG CEMENT LIME GYPSUM is dedicated to the topic of sustainability, future-proof cement production and ways to fulfil the various roadmaps of the cement and lime industry.
The cement industry still earns a huge amount of money. But it is getting more difficult to make money with cement because of the industry’s carbon footprint and the necessity for a transition to a green industry.
In the cement production process, CO2 is not just a footnote, but is now a challenge
that the industry is facing. The main source of CO2 emissions is the calcination
of limestone, a key step in the production of cement clinker.
Vecoplan presented its latest solutions for material handling at the IFAT trade fair. The engineering company has expanded its product line and now offers its customers end-to-end solutions.
The building materials industry faces the challenge of significantly improving not only its efficiency, but also the sustainability of its processes. Life cycle assessment and CO2 emissions play a central role here, as customers are increasingly demanding transparent and comprehensible information on this topic.
As the largest source of industrial greenhouse gas emissions and a key material in modern infrastructure, decarbonising cement production is crucial for tackling the climate crisis.
To support the initiative of becoming a climate neutral economy and thus contribute to strengthening the competitiveness of German industry, Open Grid Europe GmbH (OGE) presents a CO2 pipeline infrastructure for Germany.
Planeteers, a Hamburg-based Climate Tech startup, is pioneering ocean alkalinity enhancement (OAE) for carbon dioxide removal and decarbonisation of hard-to-abate industries, such as lime or cement.
Landfill diversion, lower consumption of virgin fossil fuels, lower CO2 emissions –
alternative fuels derived from municipal solid waste (MSW) offer many advantages,
but they are rarely adjusted to the needs of the customer. The Eggersmann FUEL is
different.
The German lime industry is facing particular challenges on its transformation path. It is now setting a decisive milestone on the path to carbon-neutral production with the publication of the new roadmap for CO₂ avoidance.
Europe’s largest limestone plant, the Flandersbach plant of Lhoist Germany Rheinkalk GmbH in Wülfrath, is preselected to receive funding in the amount of millions from the EU Innovation Fund.
It is perhaps the greatest challenge in the history of the cement industry: the significant reduction of CO2 emissions. An important step in this direction is the increased use of refuse-derived fuel (RDF).
stela Laxhuber Trocknungstechnik regularly trains its engineering team in the respective fields of application. For some years now, the drying of alternative fuels (AF) and refuse derived fuels (RDF) has been increasingly in focus, and not just in the cement industry.
In the production of porcelain objects, gypsum moulds are disposed of after their wastage. A process for recycling these moulds and returning them to the porcelain production is being developed and tested under practical conditions.
The utilisation of recycled gypsum is becoming even more important with the upcoming loss of FGD gypsum. While RC gypsum (mainly from recycled gypsum plasterboard) is already being used in some cases for plasterboard, its use for other gypsum products is almost unresearched. Research results on a RC gypsum plaster will be presented.
Not far from the North Sea and the city of Neumünster in the north of Germany, one of the most modern cement plants in Germany is located directly on the A23 in Schleswig Holstein. And the goal is clear: Lägerdorf wants to become the world’s first climate-neutral cement plant in 2028.
The consequences of failing to control fugitive materials include unplanned downtime, excessive cleaning costs, regulatory actions, poor public relations and safety incidents. Addressing the issues with workable long-term solutions improves availability, housekeeping and safety, ultimately enhancing the company’s cash flow.
The use of calcined clay in cement production has been around for decades, but the method has been attracting increased attention in recent years due to the associated environmental benefits. A key contributing factor to the delay in widespread commercial uptake has been the pursuit of an adequate color control strategy to minimize the reddish hue that can be present in calcined clays, to instead retain the traditional ‘cement grey’ coloring.
In the global push towards net-zero emissions, optimizing the use of coal combustion residuals (CCR) is crucial. Repurposing coal ash, a byproduct of thermal power plants, within the cement industry offers both environmental and economic benefits.
Future green cements will be produced from less clinker; and the clinker will be produced with new technologies releasing less and at someday zero CO2. Cement suppliers will be challenged to maintain consistent clinker reactivity at a lower CaCO3 content in the raw materials and with fuels emitting less CO2.
As cement is the most widely consumed building product in the world, a huge volume is produced. Cement production is responsible for about 8% of man-made CO2-emissions. The International Energy Agency (IEA) has highlighted four principal CO2 reduction levers.
