This paper explores the impact of international acquisitions on the efficiency and productivity of the cement industry in an emerging economy.

The data envelopment analysis (DEA) and Malmquist index (MI) are used to calculate the partial efficiency and productivity of individual inputs (materials, labour and fixed assets), as well as the total factor efficiency and productivity during the period 2000–2018. DEA and MI are combined with bootstrapping to perform succinct statistical inferences for determining the accuracy of results. In this paper we apply the input-oriented CCR DEA Window model. With respect to the level of analysis, data was collected from individual companies and then aggregated data at the industry level.

The research results show that international acquisitions positively affect efficiency of the cement industry in the long term. Efficiency of capital is lower in the short period after acquisitions. Additionally, international acquisitions positively affect partial productivity, as well as total factor productivity of the cement industry.

The results of the study may be significant for managers and policy makers to design appropriate strategies for the improvement of the cement industry performance over time.

Research in emerging economies related to subject matter is limited, and this is one of the earliest research studies which explore change in efficiency and productivity at the level of Serbian cement industry.

Industrial heritage is considered an essential part of cultural heritage in the world. This heritage suffers from continued marginalisation in the Arab world, particularly in Jordan, where many industrial heritage sites have not been protected or studied well due to the lack of a clear definition of cultural heritage. Most of these sites, built in the 20th century, are gradually disappearing or scheduled for demolition. This paper explores the de-industrialisation discourse and the loss of modern industrial heritage in the Arab world, especially in Jordan.

This research investigates the modern industrial heritage in Jordan as a case study in the Arab world. A comprehensive understanding of the industrial heritage has been obtained by adopting a case study approach and using a reconnaissance survey of potential industrial heritage sites in Jordan.

Seven categories were used in the analysis of the de-industrialisation phenomenon of heritage sites: ownership, location, design and types; structure, significance, deterioration and physical condition and conservation attempts and alterations. Three main approaches to industrial heritage were identified: demolition, occasional maintenance and rare examples of conservation and adaptive reuse.

This study sheds light on the ownership issue of industrial structures in Jordan and invites policymakers, relevant authorities, private organisations and the public to consider the challenges and impact of de-industrialisation of such sites.

This research raises awareness of the de-industrialisation discourse, and highlights the value of industrial architecture dating back to the modernity period, which was short-lived in Jordan. It also calls for serious consideration of these sites to support sustainable development in the Arab World.

The purpose of this paper is to describe sustainability of hollow and solid blocks in sub-Saharan Africa.

Indicators of stakeholder value are proposed for measuring block sustainability based on comparisons of user building value price and carbon emissions. Block manufacturing processes in Tanzania and Uganda are described and assessed in this context.

The results from Uganda indicate that there are economic and environmental advantages in using hollow blocks as long as they are produced to statutory compliance levels. However, where blocks are not produced to standard requirements, the results indicate that it is better to use solid blocks. This surprising result seems to indicate that blocks prepared using low additions of cement might have sufficient functional quality for simple residential building applications even though they might not meet current standard strength requirements and have low cement productivity. These results also indicate that the improvement potential indicated previously cannot be realised when hollow blocks are used for simple construction needs.

Clear benchmarks for the best practical level of cement block sustainability seem to be missing. The first reasons is that the lowest acceptable compressive strength has not been defined since standard requirements might not be relevant in the studied context. The second one is that the lowest possible practically achievable cement content with acceptable cement productivity has not been established.

Understanding sustainability can be very difficult and substantial work needs to be done to introduce operational sustainability indicators.

The results contribute to the discussion of understanding, defining and measuring sustainability.

Designing a sustainable bituminous concrete with long-term performance is a challenging problem. In addition, strength of the subgrade has a crucial impact on pavement design. This paper aims to concentrate on subgrade soil stabilization with granite dust powder (GDP) and crumb rubber powder (CRP) to improve the engineering properties of the soil. Further design of bituminous concrete pavement with cement-treated layers in base and subbase course layers was carried out with life cycle cost analysis and life cycle assessment for 1 km of a four-lane national highway.

Subgrade soil stabilized with GDP and CRP is characterized as per Indian Standards (IS)-2720 to determine the optimum dosage. Further, the mechanistic-empirical pavement design was carried out using Indian Road Congress-37 (2018), analyzed using IITPAVE software and validated with ANSYS software. The life cycle cost analysis is carried out using the net present value method, and the life cycle assessment is performed according to the cradle-to-grave approach.

A soil mix comprising 10% GDP and 2.5% CRP yielded a soaked California bearing ratio value of 6.58%. In addition, the design of bituminous concrete pavement with cement-treated granular layers showed a 26.9% reduction in life cycle cost and 59.4% reduction in total carbon footprint per kilometer compared to the pavement with traditional aggregate layers.

The research on subgrade stabilization with sustainable materials like GDP and CRP incorporating mechanistic empirical pavement design, life cycle cost analysis and life cycle assessment is limited. Overall, the study recommends the use of GDP and CRP to stabilize soil for subgrade application and incorporate cement-treated granular layers, which offer economic and environmental benefits compared to traditional pavement construction.

The purpose of this study was to improve the overall equipment effectiveness (OEE) of the production process of the shredder operation of ABC company, an industrial waste management company which supplies pre-processed industrial waste as alternative fuel to a cement plant.

This case study investigated all possible availability and performance losses that caused the shredder system’s OEE and various problem-solving techniques, such as root cause analysis and Pareto analysis, were used to find the root cause of the reduced OEE.

After analysing this case study, three significant loss factors were identified from all the availability and performance losses, which caused the shredder system’s OEE losses. Practical solutions were found for the effect of those loss factors to improve the machine’s OEE and productivity.

This case study has been concentrated on only analysing of losses and improvement of OEE in the production process and not about cost analysis between loss and improvements.

This paper shows how to improve the OEE of a production process through various problem-solving techniques by identifying its losses and how to achieve the best solutions for those losses in a practical manner.

The study enables students to critique the internationalisation strategy of an African business including elements of macroeconomic analysis, company fit with jurisdictions, non-market strategies and mode of entry.

Roland van Wijnen was the chief executive officer of Pretoria Portland Cement Company Limited (PPC), a 130-year-old cement maker based in South Africa. He joined after the business had embarked on an international expansion strategy that had taken the business to countries of Rwanda, the Democratic Republic of the Congo and Ethiopia in a matter of years. This expansion caused the deflation of the Johannesburg-listed company’s share price. The company failed to appreciate a number of success factors in each jurisdiction. The challenges included cultural misalignments, macroeconomic analysis and mode of market entry. The case dilemma involved the choices that van Wijnen faced in re-evaluating the international footprint of the business.

The purpose of this paper is to develop the efficiency of styrene-acrylate (SA) emulsions for polymer cement waterproof coatings with improved bacteria resistance and mechanical properties.

For effective bacteria resistance and excellent mechanical properties, various concentrations of methacryloxyethylhexadecyl dimethylammonium bromide (MHDB) were synthesised and incorporated into SA emulsions. The properties of SA emulsions modified with MHDB were characterised and compared with those of unmodified ones according to the formulations of polymer cement waterproof coatings.

The SA emulsions modified with MHDB exhibited significant enhancement of bacteria resistance and mechanical properties over the unmodified ones. The positive quaternary nitrogen and long-chain alkyl groups of MHDB in SA emulsions could attract phospholipid head groups of bacterial and insert them into the cell wall, which results in biomass leak and bactericidal effect. Moreover, MHDB as a softened monomer was beneficial to the synthesis of SA copolymer with low glass-transition temperature (T_g), then the copolymer and cement would form a more compact film which was the main reason for the enhancement of mechanical properties.

The modifier MHDB was synthesised from diethylaminoethyl methacrylate (DEAM) and 1-bromohexadecane. Besides, the congeners of MHDB could be synthesised from DEAM and 1-bromododecane, 1-tetradecyl dromide, 1-octadecyl bromide, etc. In addition, the efficiency of other modifications into SA emulsions for antibacterial polymer cement waterproof coatings could be studied as well.

The method provided a practical solution for the improvement of water-based antibacterial acrylate polymer cement waterproof coatings.

The method for enhancing bacteria resistance and mechanical properties of the waterproof coating was novel and valuable.

After completion of the case study, students will be able to understand the putty industry, consumer behaviour for putty, comparative advantage of putty to different industries and within industry and market entry strategy for newly introduced product.

Putty market in India grew at a compound annual growth rate of 15% over the period FY07–FY20. Many organized and unorganized players entered the putty market since its introduction. Putty was invented by cement companies to increase offtake of cement which otherwise declined owing to reduced use of marble. Painters are purchasing putty to be used before the paint to improve the texture of the walls and to fill cracks. Therefore, to take advantage of distribution channels and dealers’ network, paint companies introduced putty. Consumers, who use putty to improve aesthetics of their home, have very less knowledge about putty. They depend on painter or contractor for it. XYZ colourant company wanted to enter the white putty market to use the market opportunity along with coloured putty for economic project where cost is the constraint. This case study culminates with the probing question about the peculiarity of industry where two different industries are involved for the same product. This case study is designed to understand the target consumers’ behaviour and the entry decisions of the company to the growing market.

This case study is designed for use in second-year management programmes, especially for the students of strategic management and marketing strategy courses.

Upon completion of this study, students will be able to define, explain and describe sustainability and its application in the business context; learn and demonstrate their understanding of current practices, processes and operations in companies that are aligned to business sustainability by identifying such in the case study to enable them to provide relevant examples; discuss and describe sustainable operations and practices across different industries; identify sustainable themes in manufacturing sectors and other related industries; and identify sustainable strategies for production and manufacturing processes.

This case study focused on Gunung Raja Paksi (GRP), a steel manufacturing company in Indonesia, with a portfolio in steel trading, cement plants and carbon markets. The case study covered the COVID-19 crisis period, especially the year 2020, which disrupted the normal operations of businesses and subjected the community to economic challenges. The emergence of GRP’s prominence in sustainable business attributed to the initiatives advanced by Kimin Tanoto, the chief executive officer (CEO) and chairperson of the Indonesia Iron and Steel Association (IISIA). Kimin Tanoto assumed leadership of GRP, a family-owned business, in 2018, despite being the second son. At the time of Kimin’s induction into the board of commissioners, two main challenges – the impacts of the COVID-19 pandemic, which disrupted the supply chains, and the company culture that resisted sustainable business approaches – acted as detriments to profit-making. Sustainable efforts, however, contributed to noticeable success during and after the COVID-19 crisis.

The case is suitable for instructions in undergraduate courses in Bachelor of Engineering (BEng) in Sustainable Resources, Engineering and Management, Bachelor in Sustainable Environmental Management, Bachelor of Culture and Arts in Smart and Sustainable Design, Bachelor in Sustainable Solutions and Bachelor of Science (BSc) in Sustainable Use of Natural Resources, and other instructions on sustainable practices.

The green aspects in current management practices are strongly emphasized for sustainable and environment friendly business operations. Thus, building on ability-motivation-opportunity (AMO) theory, this study aims to test the mediating role of green absorptive capacity in the relationship between green human resources management (GHRM) practices (i.e., green training and development, and green performance management) and organizational citizenship behavior towards environment (OCBE).

Using a paper-pencil survey, the authors collected data from 170 middle-tier officers working in cement industry of Pakistan. Structural equation modeling technique was applied for data analysis through Smart-PLS.

Results indicated that GHRM practices significantly influence OCBE and green absorptive capacity partially mediates the relationship between GHRM practices and OCBE.

This study offers new theoretical and practical insights by empirically investigating the mediating role of green absorptive capacity between GHRM practices and OCBE through the lens of AMO theory. Furthermore, this study contributed in disclosing the predictors of OCBE through intervening mechanism in manufacturing sector of developing country for sustainable outcomes.
