Are carbon costs transmitting to the building materials industry?

IntroductionReconciling economic development and emission reduction of polluting gases requires balancing long-term and short-term goals across various markets. As a new production cost, the price of carbon allowances is assumed to affect the supply and demand of carbon-intensive sectors. Therefore, this study examines the dynamic price spillover effects between China as the largest carbon emission market and the carbon-intensive building materials industry in a unified time-frequency framework.MethodsThis study measures the dynamic overall and directional spillover effects of carbon and building materials markets in three frequency bands, considering eight carbon pilots and the national carbon market in China and four important building materials.ResultsThe empirical results show that the bi-directional spillover between carbon and the building materials market shows pronounced characteristics in the time-frequency domain, especially in the short-term frequency band of one day to one week, with strong connectivity. After the launch of the national carbon market, the information spillover from the building materials market to the carbon pilots become stronger. Both the carbon pilots and the national carbon market have significant short- and long-term impacts on the building materials market. In addition, there are differences in the impact of carbon markets on various types of carbon intensive building materials.DiscussionCompliance cycles in carbon markets are likely to induce sharp fluctuations in spillovers between the two markets. Therefore, balancing industrial development and stabilizing carbon prices requires a refined policy design that considers the diversified impacts of carbon markets on different industries at across frequencies.

STATE AND PROSPECTS OF THE DEVELOPMENT OF UKRAINE'S BUILDING INDUSTRY IN THE CONDITIONS OF THE ECONOMIC CRISIS CAUSED BY THE FULL-SCALE AGGRESSION OF THE RUSSIA, FROM THE POINT OF VIEW OF ECONOMIC CYCLICITY

The article is dedicated to examining the specific manifestations of economic cyclicality in Ukraine's building materials industry under martial law conditions. The analysis reveals that the full-scale war has led to the destruction of approximately 20% of enterprises, while others have experienced significant declines in production volumes, market access, raw material sources, and human resources. The features of war-induced economic crises are compared with cyclical overproduction crises, showing that military actions immediately push the economy into a recession phase. However, recovery may commence even before the end of hostilities due to the economy reaching the trough of the economic cycle.The article explores various approaches to defining and understanding the concept of "economic crisis," highlighting the importance of identifying its causes and characteristics. Key factors influencing the transition between different phases of economic cycles—recession, depression, recovery, and expansion—are identified. It is noted that the moments of phase transition are critical to economic development, as they represent the shift from quantitative changes in one phase to qualitative changes in the next.The dynamics of real estate prices are analyzed as one of the key indicators signaling the onset of the recovery phase. Additionally, the article formulates the components of a development strategy for Ukraine’s construction sector during the recovery period, taking into account the consequences of the war. These components include the localization of building materials production, improving housing comfort, ensuring the environmental sustainability of building materials, conserving resources in their production (particularly energy), involving foreign aid in the reconstruction process, and recycling demolition waste into building materials. It is determined that the future development of the construction industry must also address the issue of effectively insulating protective structures and bomb shelters with eco-friendly materials, necessitating further development of domestic building materials that meet the urgent demands of wartime. The article concludes with the prospect of utilizing hemp-lime building materials in the reconstruction process, as they fully align with the proposed development strategy

Objective: To survey the impacts of implementing new technologies with the Industry 4.0 concept in a large building materials and related products company and propose sustainable guidelines to minimize negative impacts. Theoretical Framework: Industry 4.0 technologies provide improvements in the product manufacturing process and industry performance through the use of data, but it is necessary to consider the integration of business with social, environmental and governance issues. Method: The methodological approach is a single case study, qualitative in nature, applied and exploratory in purpose. In developing the method, a list of impacts caused by the implementation of Industry 4.0 technologies was created from the theoretical framework, which gave rise to a questionnaire applied to the building materials and related products company by means of a field survey. Results and Discussion: 11 impacts were “observed” by the interviewee, 45 impacts, i.e. the majority of them, were classified as “not observed” and 10 impacts were considered to be “not applicable” to existing technologies due to the fact that the company is a retailer. After analyzing the impacts, sustainable guidelines were suggested for each negative impact. Research Implications: It can be concluded that in most of the literature searched, the economic pillar of sustainability was the most commonly found, thus highlighting the lack of analysis focused on environmental and social issues in the implementation of Industry 4.0 technology in the building materials industry. Originality/Value: It was observed that with regard to sustainability, the building materials and related products company has several very important practices, however, no studies applied to other companies were found in the scientific literature, a fact that makes the proposed work very important.

The influence of addition of fly ash from biomass combustion on selected properties of red building ceramics

The paper characterizes waste in the form of fly ash generated in a power plant during the combustion of biomass in a fluidized bed in terms of its possible use in the ceramic building materials industry. This is important from the point of view of environmental protection. In order to assess the possibility of using ash in the production of red ceramics (e.g. bricks), two different clay raw materials (Clay I and Clay II) were selected to prepare the raw material sets. First of all, the investigated fly ash was subjected to thermogravimetric TG-DTG analysis and its basic chemical composition was determined. Then the specific density was determined for all the raw materials, XRD analysis was also performed and finally characteristic temperatures were determined by means of a high-temperature microscope. The basic raw material sets included clayey raw material and fly ash in various contents: 5 wt%, 10 wt% and 15 wt%. Samples were pressed from the ready sets and fired at the temperature of 1000℃. Afterwards, the obtained samples were subjected to XRD and microstructural tests, then selected physical properties were determined, i.e. water absorption, porosity, apparent density, and compressive strength. Based on the research and analysis of the results, it was found that the introduction of fly ash from biomass combustion into the raw material set in the range of 5–15 wt% has a positive effect on the insulating properties of red ceramics. In addition, the density of the red ceramics decreases with the increase in the addition of fly ash, while its porosity and water absorption increase. Furthermore, the addition of fly ash decreases the compressive strength and visually brightens the microstructure of the products.

Operational Decisions of Construction and Demolition Waste Recycling Supply Chain Members under Altruistic Preferences

How to efficiently and greenly dismantle abandoned buildings and reuse them is a dilemma facing the building material industry’s low-carbon objective. However, relevant studies ignore the influence mechanism of altruistic preferences of enterprises on green dismantling technology in supply chains. Driven by filling this theoretical gap, this paper firstly integrates reciprocal altruism theory and the Stackalberg game method and constructs a construction and demolition waste (CDW) recycling supply chain system consisting of a recycler and a remanufacturer, in which enterprises’ altruistic preferences are considered. The main theoretical outcomes of this paper are as follows. (1) In the case of unilateral altruism, enterprises’ altruistic preference behaviors help in increasing the green dismantling technological level and the amount of CDW recycling. Under the mutual altruism model, the influence of the recycler’s altruistic preference degree on the amount of CDW recycled hinges on the remanufacturer’s altruistic preference degree. (2) The utility of the enterprises and the green dismantling technological level are optimized under the mutual altruism model. (3) In a system of unequal power, unilateral “goodwill” by the follower will have a negative effect on their own interests; the leader plays a crucial role in facilitating equal cooperation and realizing win–win situations. This paper enriches the reciprocal altruism theory in waste management. It also helps in providing guidance for the recycler and remanufacturer in making operational decisions.

Saponitecontaining Waste from Mining and Processing Companies as a Raw Material Reserve for the Building Materials Industry

A new promising direction for recycling the large-scale saponitecontaining waste from the JSC Severalmaz mining processing company is presented, the storage of which can negatively affect the ecological situation of the region and increases the risk of environmental pollution. It has been found that saponitecontaining material (SCM) in terms of MgO content can be considered as a medium-magnesian technogenic raw material for the production of magnesium cement. It has been shown that the main conditions for obtaining effective solutions based on saponite binder are as follows: the sealer is an aqueous solution of magnesium chloride at concentration of 8% and the water-to-solid ratio of 0.4. Cube samples were obtained based on a binder made from thermally modified saponite powder, taking into account the above factors, with a compressive strength of 5.78 MPa at density of 1600 kg/m3. It has been confirmed that the implementation of the above technological methods makes it possible to obtain structural thermal insulating concrete that meets the requirements of the relevant GOST.

A STATE OF ART AND PROSPECTS OF RED MUD MANAGEMENT

The basic data on the global volumes and composition of red mud, which is a highly alkaline waste of the aluminum industry, namely the Bayer process – technology for the extraction and purification of alumina (aluminum oxide) from bauxite are presented. The analysis of the current state of red mud management allows to distinguish the following main directions: physical-mechanical, physical-chemical, biological and combined methods of handling it, which are used in agriculture (chemical land reclamation (increasing soil pH), use as fertilizers); building materials industry (cement, construction mortar, expanded clay, fireclay, bricks, building blocks, ceramic tiles, concrete alkali-acid-resistant products, refractories); road construction (soil strengthening for the lower layers of the road surface, asphalt); production of other materials (sorbents, catalysts, flocculants, pigments, caustic soda, filler for polymer composites); ferrous and non-ferrous metallurgy. Currently, the most common methods of red mud utilization are its direct use, use in the construction materials industry, as well as pyrometallurgical technologies, as a result of which iron or its alloys are obtained, as well as slag, from which alumina, titanium, rare earth metals can be extracted or which is processed into various building materials. The most expedient method of red mud disposal is either direct use of red mud with minimal changes in its properties, or complex processing with maximum yield of target components and minimization of new waste generation. At the same time, one of the promising ways of red mud management can be its biological processing with the help of plants and microbes, which will help reduce the dangerous man-made load from red mud in the territory adjacent to bauxite processing plants.

Energy-saving technology of silicate pressed material with use of micro-porous silica-earth raw materials

Purpose. Research on the possibility of producing a silicate material that hardens under reduced parameters of autoclave processing, due to the introduction of natural zeolite into the raw material mixture. The methods. To solve the problems set in the work, following methods were used:generalization and analysis of theoretical and experimental data of domestic and foreign authors; analytical studies of raw materials (chemical, mechanical and physical-mechanical methods); laboratory experiment using physical and mechanical tests. The study of the properties of raw materials was carried out according to standardized methods. Findings. It has been proven that natural zeolite is an effective component of silicate pressed materials for reducing heat energy consumption during their autoclaving. It was established that with a low zeolite content, the compressive strength of lime-zeolite stone practically does not differ from the strength of limestone-sandstone. A study of the influence of the autoclave treatment regime on the strength of silicate pressed concrete, which was made using a lime-zeolite binder, was carried out. It has been experimentally confirmed that the strength-to-strength ratio of pressed silicate material on a lime-zeolite binder (compared to a similar pressed silicate material on a lime-sand binder) depends to a lesser extent on the water vapor pressure during autoclaving. The originality. The dependences of the compressive strength limit of samples-beams made of lime-zeolite binder at different mass ratios of lime:siliceous component, as well as the dependence of the compressive strength limit of silicate pressed materials on a lime-zeolite binder on water vapor pressure during autoclave processing. Practical implementation. The results of the research can be used at enterprises of the building materials industry in the production of silicate bricks. Replacing natural quartz sand with natural zeolite reduces the production cost of lime-zeolite binder, and the reduction of water vapor pressure during autoclaving of silicate pressed material on lime-zeolite binder reduces the consumption of high-value natural gas.

Comparative Evaluation of Gypsum-Based Plasters with Pistachio Shells for Eco-Sustainable Building

Agri-food waste represents a serious problem that can be overcome by converting it into added-value material for the production of plasters for green building; in fact, it can be used as a reinforcement additive in the building material industry. In this study, the performance of gypsum-based plasters with pistachio shell additives was evaluated. Before being used as additives for gypsum-based plasters, pistachio shells were ground at three different grain sizes in order to verify how grain size influences the performance of the material. Tests were then carried out on all the produced mortars to evaluate their chemical and physical characteristics, and interesting results regarding the mechanical resistance of some of the produced materials were obtained. The results showed that the addition of pistachio shells improved mechanical performance in all cases and that the best mechanical performance and water absorption by capillarity were achieved with the 0.5–2 mm pistachio grain size, while the best thermal conductivity was achieved with the 2–4 mm grain size. Summarizing, the best results were obtained with a pistachio shell granulometry of 0.5–2 mm, sand, and a water/gypsum ratio of 0.86–0.74.

An agent-based evolutionary system model of the transformation from building material industry (BMI) to green intelligent BMI under supply chain management

The building materials industry ranks first in terms of carbon emissions and energy consumption within the industrial sector. To achieve the goal of reducing carbon emissions, the development of the green intelligent building materials (GIBMs) industry has become a strategic priority and major demand for the country. Government support plays a vital role in promoting the growth of the GIBMs industry. This paper utilizes evolutionary game theory and Matlab software to analyze the impact of government regulations on the development of the GIBMs industry. The research findings indicate the following. i) Appropriate government control over building materials enterprises is beneficial for the advancement of the GIBMs industry. A balance is necessary, as both excessive control and weak control hinder the industry’s development. ii) Increased financial assistance from the government to enterprises producing GIBMs has a positive influence. This support enables building materials enterprises to overcome technical barriers, drive technological innovation, and encourage construction developers to actively purchase these materials. iii) Stronger government punishment for pollutant emissions by building materials enterprises serves as a catalyst for the production of GIBMs. Stricter penalties motivate these enterprises to adopt more environmentally friendly practices. iv) Moderate to strong government investment in infrastructure has a significant impact. It prompts construction developers to actively choose and purchase GIBMs. In response to government regulations and market demand, building materials enterprises are inclined to produce these environmentally friendly materials. This study emphasizes the importance of government regulations and support in promoting the growth of the GIBMs industry. By implementing appropriate control measures, providing financial assistance, imposing punishments for pollution, and investing in infrastructure, the government can effectively encourage the development of the GIBMs industry. These measures contribute to achieving the double carbon goals and fostering a more sustainable built environment.

New strategy for closing the plastic loop: Lightweight concrete by the waste of recycled synthetic fibers

Environmental protection related to the mismanagement of plastic waste and rational consumption of natural raw materials is an essential goal of the building materials industry and the production of structural lightweight concrete. Plastic waste is not a degradable polymer and increases severe environmental burdens each moment due to its significant quantity. In addition, the recycling of plastic materials is lower than that of other materials. It is usually described as an inefficient and complex process. The textile industry offers an eco-green, effective part of the recycling loop of plastics. Therefore, many textile mills consider recycled plastics as synthetic fiber raw material, particularly for household applications. Unfortunately, such a process results again in another waste known as popcorn. This study aims to introduce an end-of-life management option for the waste of synthetic textile fibers manufactured from recycled plastic materials in construction. Furthermore, the study presents a novel approach to develop an eco-green lightweight structural concrete by incorporating a unique type of lightweight aggregate (popcorn aggregate) as a 100% environmentally friendly product. To achieve that, fourteen mixes of fine and coarse popcorn aggregate contents (25%, 50%, and 100%) are considered to replace the fine and coarse natural aggregate by volume. In addition, the workability, compressive, splitting tensile, flexural strength, microstructure analysis, and Energy Dispersive X-ray Spectrometry are assessed. The results revealed that the higher the substitution ratio of ordinary aggregates by popcorn aggregates, the higher the slump value. Meanwhile, the unit weight of hardened concrete exhibited a tangible decrease at a 100% replacement ratio of fine and coarse natural aggregates; a 56% reduction achieved a dry density of 1059 kg/m³. Moreover, the compressive strength results indicated a decrease of 32% for mixing 25% fine e popcorn aggregate with 100% coarse popcorn aggregate, resulting in a compressive strength of 45 MPa. Fine ally, no evidence of chemical interactions between the popcorn aggregate and the cementitious element during hydration is found.

It is offered to consider the given phenomenon in the economic context through the reproduction component. The offer made it possible to formulate an approach to the creation of a mechanism for this occurrence based on the resource potential formation, the use of which should lead to increasing returns when changing a business model of a set of enterprises. The mentioned model of interaction between enterprises is oriented towards sustainable industrial development, contributes to application of new approaches to reproduction of basic funds, distribution of resources and resource base formation. The usage of the ecosystem approach while considering the issue of sustainable economic development of building materials industry stipulated interaction of related sectors as the main priority. This is done to increase competitiveness and provide the strategy of building materials industry development.

Artificial intelligence-driven photovoltaic building materials industry: Greenization and digitization innovation conversion of photovoltaic technology based on a novel interval fuzzy field theory decision-making model

Digital technologies, such as big data, the Internet, and artificial intelligence, are rapidly advancing. Photovoltaic building materials enterprises (PBMEs) have been leveraging digital transformation to enhance their technological innovation capabilities and gain a competitive edge. In the global context of transitioning towards a low-carbon economy, the deep integration of digital technology offers a new solution for the green transformation of PBMEs. The synergy between green traction digitalization and digitalization enables green practices, making collaborative integration crucial for the far-reaching development of PBMEs. Within the framework of China’s “double carbon” policy, domestic PBMEs are experiencing exponential growth, where digital green innovation (DGI) has become their primary objective. In this DGI context, selecting the right partners is the first step that significantly impacts the efficiency and effectiveness of DGI implementation. Therefore, the purpose of this study is to assist PBMEs in selecting high-quality partners, promoting the DGI process, enhancing technological innovation capabilities, and gaining a competitive advantage. To achieve this, the paper proposes constructing a theoretical framework for evaluating the DGI cooperation ability of PBMEs using the theory of ecological reciprocity. Based on this framework, an evaluation index system is established to assess the DGI cooperation ability of potential partners The interval intuitionistic fuzzy evaluation method, combined with a double combination weighting approach, is employed to evaluate the DGI ability of selected partners. Furthermore, by applying field theory, a dynamic selection model for strategic alliance partners is developed to aid PBMEs in selecting high-quality partners for DGI and facilitating the DGI process. The research findings indicate that: i) The evaluation standard framework for DGI cooperation ability of PBMEs encompasses “symbiosis,” “mutualism,” and “regeneration,” along with the crucial environmental element of mutual trust. ii) The evaluation method based on double combination weighting effectively assesses the comprehensive DGI capabilities of selected PBME partners. The application of field theory enables scientific and effective dynamic partner selection for PBMEs through resource complementarity. iii) The proposed framework and partner selection model can be employed in real partner selection scenarios for PBMEs, allowing them to choose high-quality partners, enhance their DGI capabilities, and attain practical selection outcomes. This paper presents novel partner selection model that integrates decision rules and resource complementarity, enabling PBMEs to efficiently select DGI partners from a pool of potential candidates and improve their innovation efficiency. The utilization of the double combination weighting method and field theory in the partner selection paradigm of D extends the theoretical foundation, while the establishment of the DGI capability evaluation index system for PBME partners contributes to empirical applications.
