ML/AI-based maintenance to enhance energy efficiency

14 February 2024, Published under Cement News

Recently, CemAI representatives were invited to present to the United States Environmental Protection Agency’s (EPA) ENERGY STAR® division on the topic of machine learning/artificial intelligence’s (ML/AI) use in increasing energy efficiency. The ENERGY STAR programme was interested in the role that better maintenance and control of processes could play in cement manufacturing performance. By CemAI, USA. CemAI CEO Scott Ziegler outlined the benefits of machine learning and artifici...

Unlocking cement plant potential with digital twins

30 January 2024, Published under Cement News

Cement manufacturers operate in an increasingly complex environment, facing pressure to maximise production while minimising costs and environmental impact. However, leveraging data to optimise operations can be hindered by antiquated assets and disconnected data systems. Digital twins enabled by artificial intelligence (AI) present a solution. By Wizata SA, Luxembourg Cement producers operate under increasingly complex conditions, but by leveraging data to optimise operations thro...

Net zero shipping strategies

30 January 2024, Published under Cement News

As the maritime sector looks to reduce its greenhouse gas emissions, fostering collaboration between cement producers and cement carrier operators can be of benefit to both industries. Decarbonisation options for both existing and newly constructed vessels can also enable more effective and efficient shipping operations. By Lukky Prasetyo, PT Indobaruna Bulk Transport, Indonesia. The International Maritime Organisation’s (IMO) Carbon Intensity Indicator (CII) came into force on 1 ...

Grinding for green goals

23 January 2024, Published under Cement News

As a key decarbonisation path, the research and application of low-carbon cement grinding technology and equipment can help reduce power consumption and improve clinker quality. Research by Sinoma International Engineering Co (China) reveals how to improve the grinding efficiency of bed comminution and separator efficiency while achieving low system resistance and optimal particle classification. By Chuanjie Song, Hefei Cement Research & Design Institute Co Ltd and Anhui Key Laboratory of Gr...

Maintaining quality with emission limits

19 December 2023, Published under Cement News

The trend towards more sustainable cement production and decarbonisation has resulted in increased emissions control. While this has led to challenges in terms of maintaining quality, solutions are continually being discovered.

Cost savings on the road to net-zero

12 December 2023, Published under Cement News

The road to net-zero is long and cost intensive, particularly on the process side of the building materials industry. However, a quick win on this journey is often neglected: logistics and transport. In this article INFORM explores how AI can reduce costs, lower carbon emissions and enhance customer service in cement logistics. By Dr Lars Lambrecht and Karsten Horn, INFORM GmbH, Germany. Figure 1: contributors to decarbonisation (Source: INFORM ) Even though Large Language Model...

3D printing concrete: motivations, status and outlook

11 December 2023, Published under Cement News

While automating concrete construction is not a novel idea, its more recent adoption has been driven by a need for productivity and sustainability. But what is its future? By Timothy Wangler, ETH Zürich Institute for Building Materials, Zurich, Switzerland.     Figure 1: 3D printing technology enables considerable material and carbon footprint savings (right) with structures consisting of ribbed slabs, reminiscent of Pier Luigi Nervi’s designs (left) M...

SNCR: when the equation no longer holds

28 November 2023, Published under Cement News

There are plants where selective non-catalytic reduction (SNCR) does not achieve the expected DeNO X results for no apparent reason. Often a look at the chemical processes in the background provides a clue as to why successful denitrification is failing.  By Karin Koglbauer, DyCarnica, Austria. Figure 1: chemical DeNOx behaviour-ammonia vs urea (© DyCarnica) Selective non-catalytic reduction (SNCR) refers to selective flue gas denitrification without a catalyst at 800-1100˚C. G...

CO2NTESSA’s net-zero vision

27 November 2023, Published under Cement News

The CO 2 NTESSA project will implement an innovative carbon capture (CC) technology at NEXE’s cement plant in Našice, Croatia. The existing plant will be modified based on the polysius® pure oxyfuel process, enabling it to capture more than 700,000tpa of CO 2 and a store it onshore in the Bockovci-1 saline aquifer. By NEXE Group, Croatia. The co2ntessa project will see the implementation of oxyfuel-based carbon capture at NEXE’s cement plant in Našice, Croatia (© NEXE) NEXE ...

Business models for utilisation of non-recyclable plastics in the Indian cement industry
